I found a most useful table with the right capacitor dimensions ( here, link) so no fidgeting to put in slightly different new caps. But it did arrive within 36 hours, which was impressive.įixing the boardUnsolder, remove, stick in replacement, solder.

Would they be so degraded as the Recap Kids claim they all will be after 30 years? Let's see.Īn order to Farnell was quickly made - shockingly, the price for 16 medium quality caps plus shipping came out well above the price of the entire IIe. The scietifically robust experiment: I decided to recap the whole PSU and check the state of the removed 15 or so caps. Here's how it looks now - and with the DIY done, it is time to dive into VHDL. It was time to put the Multicomp in a proper box. You can find it on my main site, here: !multicomp-fpga-cpm-demo-disk/c1fom
#Arduino 6502 emulator software
I made a disk image with all major CP/M software for the FPGA Multicomp. It is extremely Cool, so many thanks to Grant for this project! I hope it will become the launch platform for many interesting homebrewing hacks. Develop things like MMUs, so I can port OS/9 perhaps.
#Arduino 6502 emulator serial
For a further $3 or so, I can add the VGA and PS/2 connectors so it does not need a serial terminal to operate. What does it do? Well, at the moment, it runs CP/M with a 10MHz Z80 and 128MB of mass storage.The wire end then gets soldered to the little SRAM or Serial perfboard, the other end has a neat connector to plug into the dev board. I used the single Female-to-Female breadboard wires by cutting them in half. The funny thing is that it takes so little effort.

Below is a TTL-to-RS-232 board containing only two readymade converter board with MAX232s on them. What's to see here? To the right of the FPGA, there is a 128K SRAM chip ($3 or so) that is connected to the dev board. This is the glorious end result of an evening with the soldering iron:

So ordered, waited two weeks and once the parts came in, picked up a cardboard box from the bin to put it together temporarily. Add a 128K SRAM, two DB-9 serial connectors and a 5V wall wart from the spare parts box, and that's it! You do not even pay shipping costs at DX.com. $2.56 for a SD card connector board: example at DX (link) although I used one from my old parts box.$2.51 for Breadboard wires: example at DX (link).$1.63 (x 2) for two TTL to RS-232 mini converters: example at DX (link).$15 Altera USB blaster, that's including shipping cost: example at Hobby Components (link).$23.59 Cyclone II dev board: example at DX (link).It is amazing how cheap stuff is these days. This 1-day project turned out to be a introduction in VHDL, sure, but also a lesson in the economics of deflation. There is little to add to his site, so this post is nothing more than how I replicated his project. He actually did it, and I stumbled upon his project site a few weeks ago. But in retrocomputing, you have boys, men, Great Men, and then you have Grant Searle. I had been wondering how it would be to create a Lego-like box of vintage parts in VHDL and make it into a sort of virtual electronics kit. shall I add a MMU to the 6809? Or add a replica of Cromemco's disk controller so I can maybe, someday, run Z80 Cromix on this thing? It is a great way to learn about programmable hardware, where you can start straight off with something interesting and then can climb the learning curve to extend it. Brilliant! A bit like a Lego approach to retrocomputing. Mix and match parts to create the computer you like - all in a simple VHDL file a beginner can understand. If you are in Switzerland, be there or be extremely square!Ī $35 FPGA board that can mimic capable Z80, 6809 or 6502 homebrew computers with serial ports, SD mass storage and even VGA & PS/2 keyboard connectors. But there's also going to be plenty of interesting things for people who do not necessarily inhabit Planet Dragon. It seems an earth-shaking innovation in the Dragon world will be announced that night, and I do not use the term lightly. March 12th, on hacking the Dragon microprocessor goodness in general. We'll also be reviving somewhere between 0 and 2 sickly KIM-I's depending on technical skill, time and spare parts availability. But there was a great atmosphere and some surprisingly interesting Vintage Computing people to meet!įebruary 12th, on replica's like the microKIM, the Apple-I replicates and it looks like, a PDP-8 replica. At least, I think it was really nice because it was about the N8VEM and Homebrew Computing. we had the first meeting of our brand new local Vintage Computing group in Lucerne, Switzerland on January 15th, and it was really nice.
