On Recovering From Disaster

Just before disaster struck with my 68030 homebrew, I had a plan to fork the project and take it in two directions in parallel.

The first would be my minimal Multibasic setup which was running great and was something I would be proud to exhibit at VCFSW '25.

Since that was working well, I didn't want to do anything that might make it not ready for the show. So I had assembled a second main board that I could use with other peripheral cards to continue development. My plan was to rework the memory map to move ROM and I/O addresses to the upper half of the 32-bit address space, which would allow me to use a DRAM card for up to 16MB of contiguous memory starting at address 0 — a perfect setup for running a proper OS

And then I burned up my good mainboard.

I had a spare CPLD on-hand, and I was able to get another 40MHz 68EC040 for cheap. But the 4Mbit SRAM chips are expensive, and I thought that if I was going to be paying for more SRAM, I should get the 12ns parts that would allow me to run RAM with no wait states at 50MHz. Which would require adapter boards, and more pin headers, and would have just driven the cost up even more.

Paralyzed by indecision and the rising cost, I decided to switch gears. I already have the DRAM board I built years ago, I just needed to get it working. And if I'm doing that, I may as well do the work on reorganizing my memory map.

So that's what I did. I made a new branch on my newly cleaned up repository, and set to work. I updated the mainboard bus controller logic to remove the no-longer-needed SRAM control, adjust the ROM address to start at 0x8000,0000, and move the 6850 UART address to 0x8008,0000. This freed up the entire 2GB space between 0x0000,0000 and 0x7FFF,FFFF for the DRAM card to use for main memory (my bus connector layout only allows for up to 16MB main memory, but that's plenty for my purpose).

Next, I needed to build the control logic for my DRAM board. I've done this once before on my Wrap030-ATX project a couple years ago, so I used that logic as a starting point. It … kind-of worked. Sometimes. Maybe.

I was getting random errors all over the place. Sometimes it was able to copy all of ROM into RAM and verify the copy without error, but it would fail when running code from RAM. Sometimes it wouldn't even pass the first two simple tests of writing a longword to RAM and reading it back.

Back to the data sheets to plan out the logic. I drew out a new timing diagram down to 1ns resolution, accounting for the specified propagation time for my CPLDs, and the measured signal delays for my CPU. This gave me the information I needed to build out a new state machine for the DRAM controller. In the process I also caught a few other bugs in my original logic, such as not ensuring the DRAM Write Enable strobe did not get asserted during refresh cycles.

The new state machine worked much better, but I got my timing off a bit. It worked reliably at 16MHz, but not at the intended 25MHz. At least it was working though; I can move forward with 16MHz.

The next thing to do was get my 8-port serial card working with this new setup. Every time the computer tried to access one of the 8 serial ports, it would get a bus error. This was a tough one that had me stuck for a while.

It looked like the serial card was getting addressed and asserting DSACK0# as expected, but I couldn't confirm the signal was making it back to the CPU. Every time I tried to measure the DSACK signals, the probes would increase the line capacitance (I think) too much and cause the whole computer to fail before it even got to the point of trying to address the serial ports.

I have the DSACK signals in a wired-or configuration. The logic on each card connects to the proper DSACK signal via an open-collector buffer, and is able to pull the signal low to signal that card acknowledging the bus cycle. The signal is then pulled back up to +5V by a 1kΩ resistor. This works well enough for small, slow systems, but with long bus wires or lots of chips on the bus, the extra capacitance means it can take a long time for that pull-up resistor to get the signal back up to +5V.

I made a change to my DRAM controller to actively drive the DSACK signals to +5V briefly at the end of a bus cycle before setting the pin to high-impedance. This helps ensure a fast rise time at the end of the cycle so it doesn't disrupt the next bus cycle.

It didn't fix the problem with the serial card, but it did allow me to actual probe the signals live to see what was happening — the Bus Error signal was getting asserted immediately after the CPU addressed the serial card. This didn't make much sense to me. My main board logic will assert Bus Error if no peripherals acknowledge a bus transaction within 64 clock cycles. Nothing should be asserting Bus Error so quickly.

Except … the main board bus controller. My original memory map used the lower half of the address space for the main board, and peripheral cards used the upper half. So my original main board logic was built to assert Bus Error immediately for an unused address in the lower half of the address space. I hadn't properly removed that bit of logic, so it was now asserting Bus Error for any accesses to the upper half of the address space that weren't used by the main board.

The challenges of working on a project after six years. I had forgotten that bit of logic was even there.

With that erroneous Bus Error assertation removed, the machine was finally able to properly load my Multibasic kernel and run BASIC for 8 users again.

At the moment it is running stable at 24MHz on my 25MHz-rated full 68030. It may not be the 50MHz high I was at, but after the frustration and disappointment of the past few weeks, I'm absolutely taking that as a win. 24MHz is incredible.

Espressif programmer test success! 💻✨🔧

While developing boards, there are oftentimes we want to program ESP chips without going through the onboard USB port; this adapter will help us (and others) do that! It has a CP2102N USB-serial chip

https://www.digikey.com/short/bm7n3p5z

...with RX/TX signal LEDs and two transistors wired up to the DTR/RTS line for the 'esptool standard' reset procedure technique. The output IO, plus a 3.3V 500mA regulated output, is available on a socket header, so you can plug wires in for quick programming and debugging. You can use this for everything from an ESP8266 up to the ESP32-P4! Here, we are testing it with a HUZZAH ESP8266 breakout board

...one of our first Espressif chipset products.

An invitation to a “candlelight” dinner held this past Saturday at President Donald Trump’s Mar-a-Lago club asked prospective guests to spend $1 million per seat. Trump attended the dinner along with Elon Musk, according to multiple photographs and videos of the event viewed by WIRED.

Elon Musk, wearing his standard uniform of a black sport coat over a black T-shirt, was seen shaking hands and waving to other attendees. He was with a woman wearing a floor length gown who appeared to be Shivon Zilis, according to Instagram Reels posted by multiple guests. Zilis, a Neuralink executive who previously sat on the board of OpenAI, is the mother of four of Musk’s 14 known children. (Zilis did not immediately respond to a request for comment.)

Musk, whose so-called Department of Government Efficiency has spent the last six weeks ransacking federal agencies, sat next to Trump at the dinner.

WIRED previously reported on another candlelight dinner held on March 1 where guests were also invited to spend $1 million per person. That event appeared on the president’s public schedule with a note reading “the President attends the MAGA INC. Candlelight Finance Dinner.” The March 15 candlelight dinner did not appear on the official schedule.

“You are invited to a candlelight dinner featuring special guest speaker President Donald J. Trump,” states the invitation, obtained by WIRED. “$1,000,000 per person.” The invitation has a “MAGA INC.” header and a note at the bottom of the invitation reads, “Donald J. Trump is appearing at this event only as a special guest speaker and is not asking for funds or donations.” MAGA Inc., or Make America Great Again Inc., is a super PAC that supported Trump’s 2024 presidential campaign.

WIRED has also reported that business leaders could secure a one-on-one meeting with Trump for $5 million at Mar-a-Lago. The $5 million meetings have become a “hot ticket” in the business community, a source familiar with them previously told WIRED.

The White House did not immediately respond to a request for comment about the event or the lack of the event’s inclusion on the president’s official schedule.

Experts WIRED has spoken with about these candlelight dinners have noted concerns about their unusual nature. “I can’t recall a sitting president in the first weeks of his administration asking for millions of dollars in fundraising,” Don Moynihan, a professor of public policy at the University of Michigan, previously told WIRED. “The concern is less about fundraising and more about access and influence. People hoping to get favorable treatment view it in their interest to donate money to Trump.”

The candlelight dinner occurred over the same weekend as the Palm Event, an annual celebration of motorsports in Palm Beach, Florida. One of the celebration’s weekend events occurred at Mar-a-Lago on Sunday afternoon and featured “street sportscars and cars with a motorsports heritage, one-of-a-kind, concept cars, celebrity-owned and cars with a racing history,” according to the Palm Event website. A number of these cars appeared the night prior at the candlelight dinner, according to Instagram reels that featured guests milling around a Rolls Royce, Bugatti, and Lamborghini, among other luxury vehicles displayed on the lawn.

The evening also coincided with a serious escalation in Trump’s crackdown on immigration. On Saturday, while Trump and Musk dined with MAGA donors, a federal judge ordered the White House to stop the deportation of people the Trump administration alleged were Venezuelan gang members. Despite that ruling, two planes carrying the alleged gang members flew from Texas to El Salvador. Senior officials reportedly told Axios that the ruling held no force “because the flights were over international waters.”

DIY: Making A Pwnagotchi

Yes, I know I am very late to the game ... LOL I was meddling with Flipper Zero and war driving, then I came across the Pwnagotchi project. Since I already had the parts to do this lying around in my workshop, I decided to put together my own Pwnagotchi just for fun. Started by hooking up the Waveshare 2.13" Black and White E-Ink Display to a Raspberry Pi running a fresh Raspbian image and downloaded the Waveshare demo code to test the display to make sure it's working properly, since I have not actually used it before. This is a v4 display.

After that, I just followed all the instructions over here to put it all together, including adding a real time clock. I used the DS3231 RTC module designed for Pi, but in order to make it fit into the space between the display and the Pi board, I had to make some modifications. The female header pins on the RTC module was desoldered and short wires were soldered on. The battery also had to be desoldered and resoldered on in a new positionlike below to make the module thin enough. The module was then wrapped in wire tape for insulation. Now, we can just slot the wires into the female header pin holes of the display before we snap it onto the Pi board.

Below, you can see the RTC fits comfortably between the boards. I also attached a UPS Lite v1.2 board. Apparently, the UPS Lite board I had was a clone/knock off. It uses I2C address of 0x32 instead of 0x36 that was used in the original product, so the UPS Lite plugin in Pwnagotchi won't work. Oh well, I will just use it like a normal battery pack.

Now, for the software. The original Pwnagotchi project has not had any new updates for over 2 years, so it's kinda out of date and it doesn't support the newer Waveshare displays. Luckily for us, someone had taken the effort to fork the project and released new versions of Pwnagotchi over here. Note that this requires Raspberry Pi Zero 2 W.

The Waveshare 2.13" E-Ink display that I had was v4, but I found that I had to set the display type to "waveshare_3" in Pwnagotchi settings for it to work properly. Next is to 3D print a case for this, but in the mean time, I used some nano bricks to build a temporary case for it.

That's it for now. Happy hacking!

fanfic writer ask game -> 85!

85. what would be on a moodboard for your current wip(s)?

Ooh! This a fun question, but very difficult for me, because my brain is really not wired for all the visual stuff…I love seeing everyone’s fic covers and moodboards, but I don’t have the skills to make one myself.

But let’s talk about Hosie Historic Preservation, my Hallmark-style fic idea for this year’s Christmas fic (hopefully 🤞), which I’m trying to write on for as long as my brain’s up for it right now 🤞

So we’re gonna have pictures of the Salvatore Boarding House—the exterior, the library, the fireplace. And since it’s winter and Christmas, small-town town square in the snow and/or decorated from Christmas (probably some screencaps from TVD would have this from Covington/Mystic Falls?) A ski slope nestled among verdant trees. And some stills or screencaps from 2x08 “This Christmas Was Surprisingly Violent”—especially this one:

Some more baked goods (a basket of muffins?). A clean yet homey, cozy bedroom, quilt on the bed. A radiator. But also some images of peeling paint and cracked plaster, that sort of thing.

A businesswoman in a powerful blue pantsuit, maybe a Louboutin seen from behind. A shot of some part of the NYC skyline with high-rises and skyscrapers (again probably in the snow). Part of a deed or contract, worn and faded somewhat by time (but not too much…it’s not necessarily that old). Maybe a ledger showing lots of red? A black limo. A bank safety deposit box on a table, with its lid leaning against it. A section of cemetery with several headstones.

The Talisman of Sound.

I’m not sure what sort of image of Hope specifically I’d choose (unlike Josie, where I’d seen that specific one recently). Aurora looking shifty or menacing. Maybe Maya looking excited or Landon looking goofy in love? Sebastian looking very old-timey. Penelope with a smirk. Grandma Mary. Lizzie…I don’t have a specific idea for her, either…happy and free, but beyond that?

And then some tender, intimate, dim/poorly-lit (😂) Hosie scene, because Hosie endgame, of course! (If all else fails, the one I’m using as my header image, even though there’s no magic in this fic.)

I’m only about 5K words into this, Hope and Josie haven’t met yet, so I don’t know more than the skeleton of the story arc (I don’t even know what the role of the talisman is going to be), and it’s possible that I’d have other things I’d add later…but these are the kind of vibes (and a few spoiler-ish references 😂) I’m working with so far.

Thanks for the Ask! I hope the answer was interesting 😀

Prelude - 3

The floodlights began to brighten as minutes ticked by. The lone occupant of the small balcony-turned-workstation looked up, watching the artificial light stream through the metal mesh above her head, and sighed.

Layan Rizk had stayed up all night again… thankfully tomorrow was a weekend.

She stretched her arms, leaning back in her seat before leaning back towards the desk. The PCB she was working on had no eyes to stare back, but the soldered pins glimmered in the dim light nonetheless. She picked it up gingerly, trying to avoid stirring the connections too much. Thankfully she remembered to put on her gloves this time— she couldn't have this board short out and fry the processing chip again. Nujum needed this whip-blade for her breaker training on Sunday, lest she get scolded by the teachers again. Last time that happened, she had come back to the little apartment they shared, crying— and was inconsolable for days.

Layan shook her head, dismissing the image out of her head. She hated seeing her younger sister crying like that. Busying herself with her work again, she took a glance towards her computer, busy flashing something onto a USB drive. The terminal log breezed past, text flying across the screen far too quick for her eyes to comprehend anything past "units" and "gtx_ctrldrive"—

The racing terminal freezes in its tracks. The cursor apologetically blinks at the end of a red line of text.

[USB_MSU61527] Could not install loader – you have held broken packages_

The girl stared at the screen, blue eyes narrowed in confusion. "Wha… broken what now?!"

Layan scrolled up in the log. It had been writing just fine to the drive earlier when she had used it to flash a new bios to the main board, just what was wrong with it? Had the drive finally given out after years of use?

Her phone pings with a message, and she fishes it out of her pocket. With the electrical gloves still on, it doesn't respond to her touch, but she can see she's got a message. Her friend — someone she's met on the Axia xenocryst modding forums — had sent her a picture of a Buuma gauntlet in atrocious shape. The gauntlet in the image looked completely busted, finger compartments bulging, capacitors drenching the boards with now caked-on fluid, wires blackened with electrical overflow. Even without the electrical damage, the gauntlet had holes in it; square edges with the aluminium bursting outward like the blooming petals of a flower. Her friend had captioned the image, too;

fluxnux: look @ what i found in my dads bodydock wastebin

blown axia serie 16 buuma, who wants it

think it belonged to a lcient or smth

cliwnt*

yk what i mean --

Layan quickly typed a response, intrigued enough to forget her own mechanical woes for a second. She exited the installation process and let her PC idle as she looked over the latest offering from Fluxnux, seasoned anonymous xenocryst modder. Most of what Nux gave her tended to be already dead implants, but they were possible to use for parts or, in one bionic arm's case, repairable into test benches. This one was quite a sight however. Layan found herself more intrigued by the story behind this than its capabilities.

rzk81: Holy shit. That's frightening

Is it salvageable?

fluxnux: r u kidding?? total ewaste

wanted a regulator chip off it but no luck. shield headers are still functional somehow and i think u can MAYBE get cords + heatsink + ports off it

but thats it

everything else is either blown or busted.

rzk81: What happened to it?

fluxnux: overcharging

The girl tensely swallowed, that one word sending a shudder through her that definitely wasn't the fault of the cold. She's never seen anyone actually experience an overcharging incident in-person, but she's heard enough horror stories through her older sister, Dani, to know they were caused by overuse of xenocryst equipment.

Seeing the way this buuma was all but torn to pieces, though… it made the fear a lot more present, the danger a lot more tangible. She examined the image a lot more closely as her friend continued typing away. Zooming in, she could see the muted brown of the capacitors, realizing those were made for a Yellow serotype. The blackened parts of the aluminium seemed to spread out from the wrists, like the user had been engulfed in flames… or worse.

She glanced at her own hand, blue ripples of marble shining from underneath her sleeve, running up her palm, and swallowed thickly.

Can't think about that right now.

fluxnux: i think dad got it off a invil

explains y its so fuckin wrecked

probably got into a huge fight lol

An invigilator overcharging? Now that wasn't good. Layan found herself thinking of Dani again, of the invigilators' cadet academy submission forms on her eldest sister's desk, papers of relocation and medical records stapled to them. The worry came to the surface again, and she couldn't help but type out a tense reply to Nux, the sound of idling fans now deafening in her ears.

rzk81: Invigilators have overcharging training though, don't they?

fluxnux: guess yhis one was just stupid ┐⁠(⁠´⁠ー⁠｀⁠)⁠┌

She couldn't help but snort, despite her mounting anxiety.

rzk81: Very classy, Nux.

fluxnux: you want it or not?? dads taking it to the processing center today

rzk81: I do need replacement USB-X ports. Send it over

fluxnux: 👍

btw

hows ur project going

Layan pursed her lips, glancing towards her computer, still idling. The computer continued to hum as she set it to hibernation mode, and Layan rotated the USB stick between her fingers as she read the messages. She let out a tired exhale, leaving her desk as the floodlights came into full power. She'll work on it… tomorrow, but advice in the meantime won't hurt.

rzk81: horrible.

Ever heard of a "you have held broken packages" error?

fluxnux: reinstall dependencies + system updates

should fix it

rzk81: Thanks

fluxnux: whats this hanash for anyway?

never saw anyone attempt shaving a board like this before

challenging urself with a small form factor?

Now on her bed, the girl's blue eyes drifted shut as she thought. Nux knew she was working on something— she had been enjoying their attention to her work and the free tech support that came with it. Guess she should've known it wasn't entirely free.

Still, Nux has been trustworthy so far. Would it truly hurt to actually say what she was working on this whip-blade for? That she was just helping out her younger sister when they didn't have the means for proper equipment, and Dani wouldn't touch any xenocryst tech with a ten foot pole?

She tensely hovered a finger over the message, before steeling her resolve and holding down to reply. They didn't need to know.

If there was anything her parents had taught her, it was that she couldn't trust anyone in Amon.

rzk81: You can call it a commission I guess.

fluxnux: damn get that bread

gl

Despite her better judgement, Layan found herself smiling, if just a little.

…she would be lying if she said Nux wasn't growing on her.
