Sharing a Computer with More Friends

A few months ago I built an I/O expansion board for my homebrew 68030 project with a 4-port serial card to go with it, and got BASIC running for four simultaneous users. It worked, but not as well as I had hoped. I wanted to be able to run two of those serial cards to support 8 total users, but it had proven unstable enough that with just the one card I had to slow down the whole system to 8MHz.

So I designed a new serial card.

I had previously been running this computer without any issues at 32MHz with a mezzanine card with FPU & IDE as well as a video card. The main board by itself can clear 56MHz. Having to go all the way down to 8MHz just didn't sit well with me. I want this machine to run as fast as possible for its 8 users.

I put extra time into reviewing worst-case timing for all components and graphing out how signals would propagate. The 16C554 quad UARTs I'm designing around are modern parts that can handle pretty fast bus speeds themselves — easily up to 50MHz with no wait states on the 68030 bus — assuming all the glue logic can get out of the way fast enough.

Signal propagation delays add up quickly.

My first draft schematic used discrete 74-series logic for chip selection, signal decoding, timing, etc. At slower bus speeds this wouldn't have been a problem. But I want this thing to run as fast as possible. By the time critical signals had made it through all those logic gates, I was looking at already being well into one wait state by the time the UART would see a 50MHz bus cycle begin.

I needed something faster. I was also running low on space on the board for all the components I needed. The obvious answer was programmable logic. I settled on the ATF22V10 as a good compromise of speed, size, availability, and programmability. It's available in DIP with gate delays down to 7ns. Where discrete gates were necessary, I selected the fastest parts I could. The final design I came up with showed a worst case timing that would only need one wait state at 50MHz and none for anything slower.

It ended up being a tight fit, but I was able to make it work on a 4-layer board within the same footprint of my main board, putting some components on the back side. (It may look like a bunch of empty space, but there's actually a lot going on running full RS232 with handshaking for 8 ports).

New problem. I had blown my budget for the project. As much as I love those stacked DE9 connectors, they're expensive. And there's no getting around the $10 pricetag for each of those quad UARTs. Even using parts on-hand where possible, I was looking at a hefty Mouser order.

[jbevren] suggested using ganged RJ45 connectors with the Cisco pinout instead of stacked DE9, to save space & cut costs. [Chartreuse] suggested buffering the TTL serial TX/RX signals to drive the LEDs that are frequently included on PCB-mount RJ45 connectors. Both great ideas. I was able to cut 20% off my parts order and add some nice diagnostic lights to the design.

Two weeks later, I received five new PCBs straight from China. I of course wasted no time setting into starting to assemble one.

I really set myself up for a challenge on this one. I learned to solder some 25 years ago and have done countless projects in that time. But I think this might be the most compact, most heavily populated, most surface mount board I've ever assembled myself. (There are 56 size 0805 (that's 2x1.2mm) capacitors alone!)

After a few hours soldering, I had enough assembled to test the first serial port. If the first port worked then the other three on that chip should work too, and there's a great chance the other chip would work as well.

And it did work! After some poking around with the oscilloscope to make sure nothing was amiss, I started up the computer and it ran just fine at 8MHz.

And at 16MHz.

And at 25MHz.

And at 32MHz.

And at 40MHz.

And almost at 50MHz!

Remember what I said about my timing graphs showing one wait state for 50MHz? The computer actually booted up and ran just fine at 50MHz. The problem was when I tried typing in a BASIC program certain letters were getting switched around, and try as I might, BASIC just refused to 'RQN' my program. It was pretty consistently losing bit 3, likely from that signal having to travel just a tiny bit farther than the others. A problem that will probably be resolved with an extra wait state.

Good enough for a first test! A few hours more and I finished assembling the card.

I did have some problems with cleaning up flux off the board, and I had to touch up a few weak solder joints, but so far everything seems to be working. I've updated my little multi-user kernel to run all 8 users from this new card and it's running stable at 40MHz.

I need to update my logic on the 22V10 to fix a bug in the wait state generator. I would love to see this thing actually running at 50MHz — a 25% overclock for the 40MHz CPU I am currently running. I also want to expand my little kernel program to add some new features like the ability to configure the console serial ports and maybe even load programs from disk.

I hope to bring this machine with a collection of terminals and modems this June to VCF Southwest 2025 for an interactive exhibit that can be dialed into from other exhibits at the show.

DB9: The Little Prince of Ports

On Asteroid Tech-612, where copper vines twist like baobabs and circuits glow like stars, there lives a small connector with nine golden pins—the DB9. Though newer ports boast flashy speeds, this humble traveler guards factories and hospitals with the quiet wisdom of the Little Prince. Let’s wander the cosmos to learn why galaxies still whisper its name.

1. The Prince’s Humble Asteroid

The DB9 thrives where others fear to tread:

Volcanic Factories: Welding sparks fly like comets, yet its pins grip tighter than the lamplighter’s devotion.

Ice-Cold Hospitals: -40°C MRI rooms? “What matters is invisible to the eye,” it muses, steady as a heartbeat monitor.

Dusty Aviation Hangars: Guides planes through storms, unbothered by lightning’s tantrums.

Why USB-C’s planet fails:

“Too busy counting pins to see the stars.”

2. Journey Through the Planets

Planet of the Welding Robot: “Why do you spark so much?” asked the Prince. “To forge constellations,” DB9 replied, its RS232 voice cutting through EMI like a fox’s whisper.

Planet of the Retro Gamer: Between pixelated explosions, DB9 sighed: “Grown-ups rush; my N64 savors every frame.”

Planet of the Grumpy Engineer: Thumbscrews locked like secrets. “USB snaps. I endure,” said DB9, polishing oxidation off pin 5.

3. The Fox’s Secret

“Tame me,” begged the EMI interference. DB9 shook its head: “My shield is simpler: ±15V logic and a grounded heart.”

4. The Businessman’s USB-C Empire

“I have 24 pins!” boasted USB-C, drowning in dongles. DB9 watched a CNC machine carve roses: “Your speed is fleeting. My 1,000+ insertions? Eternal.”

5. Where Roses Still Bloom

Industrial Deserts: DB9 outlives touchscreens in forklifts, smiling as sparks dance like fireflies.

Medical Oases: EKG machines cling to its pins—steady as the Prince’s rose under glass.

Retro Gardens: Where GoldenEye 007 never dies, and USB adapters wilt like plastic baobabs.

Epilogue: The Connector’s Cosmos As rockets chase thinner ports, Asteroid Tech-612 glows gold. For what is essential—endurance, simplicity, a thumb-screw’s embrace—no algorithm can replace.

In the Beginning: The History and Evolution of Device Servers

Lantronix PremierWave EN dual band WiFi device server

In the beginning (well the 1980s), there were terminal servers. And they were good. These devices allowed for dozens of ‘dumb’ terminals to be connected to a mainframe or minicomputer over a single wired Ethernet connection. They were widely deployed at banks, automotive dealerships and insurance companies - anywhere a concentration of computer users was to be found. One of the main benefits was not having to run yet another cable all the way from the main computer to the new terminal location. As these terminal servers advanced, they allowed for another level of authentication to be implemented, via local username and password. Savvy administrators started finding ways to also connect printers to these servers and ultimately, terminal server designers added direct support for print queuing. This was a substantial timesaver, as now the printer could be placed near the user without a dedicated drop. Since some printers were installed remotely without associated terminals, it was a natural extension to create a terminal server dedicated to attaching printers to the network. With this, the print server was born.

With the explosive growth of microcontrollers in products, a plethora of equipment that had serial connectivity began to emerge. Asynchronous serial was a well-established means of communicating with a computer and with the addition of a UART and line driver, it became easy for a designer to allow a way to interface with their new products. The problem then was that serial only worked well over 50-100 feet, depending on data rate. Someone came up with the idea of using a terminal server to connect these products (alarm panels, industrial equipment, medical devices, etc.) to the network. Most of the available terminal servers had high port counts (16, 32) so it was rather expensive to use a terminal server on the shop floor to hook one or two machines to the network. Lantronix solved this problem by creating 1-, 2-, and 4-port ‘serial servers’ as they were first branded, later coining the term ‘device servers’.

Initially, device servers were external ‘box’ products consisting of a small plastic or metal enclosure, which contained the serial-to-Ethernet conversion circuitry, regulated power supply, led indicators, Ethernet connector (RJ45) and the requisite RS232 connectors. Over the years, these boxes have shrunk in size and added additional interface types, including RS422 and RS485. Originally, the software enabled basic serial-to-Ethernet conversion (often called ‘tunneling’). As technology advanced, the firmware became much more configurable and for some applications, became protocol-aware. This was important because if data was not properly packed into a TCP (network) packet, it could become fragmented when arriving at the other end of the connection. This fragmentation could cause timeouts and other bad behavior from products and software used to having a direct connection.

In the late 1990s, web servers were added to device servers, giving them a new way of being configured and for data presentation. At this time, OEM manufacturers inquired about embedding device server functionality onto their main boards. Small products specifically designed for being embedded were created. These dispensed with the power supply regulation and serial interface circuitry. They were ideal for integrating to a main board, requiring only logic level power and signals. True to device server technology, they handled all of the tasks associated with getting a machine on to the network. It made networking easy for an OEM. In 2002, Lantronix changed the face of embedded device servers when they came out with the ultra-miniature XPort. This was a complete serial-to-Ethernet device with web server in a standard sized RJ45 jack (about the size of two sugar cubes). Millions of these devices have been deployed worldwide.

The next logical step was to branch out to additional transport types including wireless 802.11. Both embedded and external device servers have been produced utilizing the ever improving 802.11 standards. 802.15.4 and Zigbee have also benefited from the creation of embedded modules.

While many additional customer interface standards have been created, asynchronous serial is still the most common way device servers are connected to equipment, both in embedded and external applications. More recently, SPI has become interesting for high-speed transfers from an OEM main board to an embedded device server, as well as 802.3 wired Ethernet (“bridging” to 802.11 wireless).

Where are device servers headed? Physical size reduction is always foremost on the list. Also having faster ways to interface to an embedded device (i.e. SPI, USB, etc) to improve overall bandwidth. It has been imperative to add additional compute power and memory resources for tackling increasingly complex encryption and authentication methods. This extra ‘horsepower’ has obviated the need for a main processor in some embedded applications. It’s funny to think that just eight years ago, a device server might be able to execute 30 million instructions per second. Now it is upwards of 400 million! Additional I/O capabilities allow a wider variety of sensors and other peripherals to be attached to a device server. And of course, keeping up with the latest standards in wired and wireless communications is a must. Device servers have come a long way, but the goal remains the same: Handle all communication tasks from A to Z, whether wired or wireless, and provide a very easy-to-implement solution that keeps the customer focused on their core business and gives them a huge time-to-market advantage.

I've also seen these on custom AV installations where a single large cable is used to run a number of different signals a decent distance, and then breaks out into a cable like this on either end. I've personally installed some that use a half inch thick cable terminating on both ends with a DB25 connector, and a breakout cable that has two RCA composite video, RCA mono audio, RJ45 PTZ camera control, RS232 terminating in a DB9. Here are some of the cable diagrams for those cables:

Cable T511 was 50 feet of 1/2" thick cable. It was a beast to run, and we'd usually have at least 2 of them.

Here's another cable diagram for another of the cables that came in the kit:

For those interested in learning more, this is from the Tandberg Educator MXP classroom video conferencing system. https://www.clarybusinessmachines.com/products/files/tandberg/tandberg_educator_mxp_user_manual.pdf

any idea what this cable is?

looks like 9-pin vga on one side then breaks out into 7 wires labeled composite? on the composite side, one red wire is labeled "Composite Sync Output", one blue is labeled "C/V Sync Output", one green is labeled "Y/H Sync Output", and the black wire is labeled "Composite Video Output". the cable itself has a tag that says "cable from splitter to monitor"

That's probably designed for some specialist video card that generates output for professional video production. That's why it's got separate syncs, because that's often needed to properly genlock all the stages.

No idea what specific card it is, or what device you'd plug it in, but this is the kind of cable that gets custom made for one specific card type and the next card will use a completely different cable, so both the cable and the card are useless when they get separated, as they inevitably do :(
