Same idea as the Introduce yourself topic, so our new members can introduce themselves.
There's no guideline for length of biography yet, so I guess I can do whatever I want. Please everyone, let's try to keep this as introduction only. For example, if you want to discuss a project someone mentions, please start another topic for it, instead of cluttering this one with things that are not strictly introductions.

Hi. My name is Chuck. I am a Commodore 64, 128 and Amiga user. The C-64 is the only fully working hardware I have left. I have many boards including AT Tiny, Arduino, Microchip Pic, Stellaris, Raspberry Pi and Gameduino.

Commodore went bankrupt and no one seemed to be doing anything to further development on their hardware so I have been surveying the available off the shelf parts that could be used to make a single board computer.

I have almost settled on the STM32F407 HIGH PERF DISCOVERY BOARD as my CPU of choice: ... N8XDBeCtgD

But it requires a ST Link or Jtag wire to program. I have some ARM chips in dip form that can be programmed with an FTDI cable or USB dongle using BASIC. I also have some development kits for the STM 32.

Progress has been slow as I am happily married and I am a busy person. I've built a joystick shield for my Gameduino, soldered a standard HD44780 LCD to pinheader for breadboard use, built a TV-B Gone and a Timesquare watch kit. I still have an LOL shield and a BoArdino to build for an LED cube.

I'm still transitioning from reading and learning to actually doing more as I am a beginner with a lot of inexpensive hardware stuff but I do have some basic soldering skills.

I'm interested in new boards, new solutions and new graphic and sound chips that can be used.

Im James Parsons. I do 6502 and 6800 work. Oddly, Im only 15. Most of my 6502 work is with the C64. My 6800 work is with the swtpc, and any thing I want to build

Hi, I'm Ed, and oddly I'm (only) 51... I'm mostly interested in the 6502, but also building custom CPUs or variation CPUs. I converted Arlet's 6502 core into a 65Org16 (see github) but I've actually done very little with FPGAs. If I had more get up and go I would have done something practical on the 65Org32 by now. To be honest I'm interested in most computer-related topics up to about 1980 - a lot of interesting stuff happened in the 50's, 60's and 70's. I wrote up a self-intro introduction over at too, and you'll find me over on gplus, co-authoring the mos6502 page and co-moderating the Retro Computing community.
I once bought a Vectrex which always springs to mind when I see a 6809 project - and I did a short course once which used the 6800 in a trainer system.

I am remiss in not introducing myself here earlier. I posted an introduction at, but really, I'm interested in all kinds of computer architectures. Like Ed, I'm fascinated by architectures from the '60s, and '70s, but I'm also interested in some of the newer microprocessors (like the MSP430, which may be as close as you can get to a PDP-11 these days).

My main "academic" interests are computer languages, operating systems, and computer architecture, which led me early on to an interest in the Forth language. My "practical" interests are embedded and small systems. I did design and prototype my own CPU from 7400-series TTL, which I'm hoping to turn into a PCB some day soon...time permitting.

1802, 6809, 8051, 8086, MSP430, Z80 -- there's a Forth for that:

Hi Brad - it would be great to see any pictures or info you have of that TTL cpu!

Hi! Just registered here having been on for some time. I'm interested in the 6809 CPU, as well as the 68000, although I do quite a bit with the Atmel AVR chips nowadays.

Back in the day, I wrote 6502 code on a Compukit UK101. We had a Commodore PET 2001-8 at school, too. I built an Acorn System One for the school electronics lab, also 6502-based. At Uni (Westfield College, London) I dreamed of building a 6809 machine and went as far as buying a CPU chip, but never got much further than that. After Uni, the Atari ST and its 68000 chip was popular, and I had one with a hard disk (ST225) attached. I wrote a 6502 simulator in 68000 assembler for the ST.

Work has taken me from 8086 coding in London, to working with the transputer at INMOS, to designing hardware and software for the AVR. Part of my work with the transputer led to sending them over the side of a ship in a sonar towfish system.

But now I'm keen on combining the AVR with a 6809 chip in some way. I've seen it done recently on Hackaday with a 65C02 and a PIC.

Welcome! Indeed, using a microcontroller to implement the glue and peripherals is a nice way to simplify the electronics. Just about feasible now to run at speed.

I'm river and I am from Australia, and I am in the last few working years of my life before I happily retire to lay siege on my hobbies: :D

My interests and knowledge in various processors is, depending on the device, shallow or fairly deep. Back in the late 70s when I was doing my Electronics & Communications certificate, I got a keen interest in microprocessors. We used TTL-based systems where I worked, but they soon got into microprocessor controllers. I was like a sinkhole back then and I sucked it all in and couldn't get enough.

The Intel 8085 was the first processor I got my hands on, as that is what the equipment had where I worked. Some had 8080 CPUs and I got dirty with that chip too. So, my main knowledge is the 8080/85 cpu and a few of their peripheral devices.

We used a KIM at tech college and that is how I got to meet the fabulous 6502. I wanted one so I forked out big money (at the time) for an AIM65. I ended up with a few of these and one of them I am modifying. I have wire wrapped up an expansion board, and it now runs 40K RAM, 6522, 6520, 8255, 6840 and 6551 devices. I am now looking at changing the ROM code to remove the RS232 bit-banging and use the 6551. Also adding code to allow downloading of hexcode.

Other processors I have programmed and built, and still have them all and they are operational include Z80, 6800, 6802, 6809, SC/MP, 2650, 8086/88 and 68000. These include home built as well as S100, Multibus I, Exorcsiser or STD bus stuff.

I guess the 8085 is my all time favourite cpu, with the 6502 being a very close second. I don't think a 6502 system is complete until it has an 8255 in it :)

Over the years I have set up a small electronics work room. Alas, the era of board level repairs is gone, but not for me. I still dabble and play around with this old kit. Over the years I picked up cheap chips to ensure I had a supply of spares and have enough stock to keep things going as well as build quite a few more systems.

I play around with the Atmel AVR processors, and I got some PIC stuff also but haven't used it yet. This is Mikroelektronika stuff, which I am enjoying.

I like vintage 70's audio so often my hobby time is split amongst fixing and restoring old amplifiers, receivers, tape decks or turn tables, and then when got some time I play with the old processors.

Won't bore you anymore :)

Hi. Stefan is my name, 40 years old, and I live in Sweden.

Been a software person since I was about 10, with BASIC on VIC20, C64, MSX and various other 8bit machines. After that I went on the Atari ST side (Amiga sucks!! :) (Ok, not really)), with ST, STe and Falcon. First BASIC (GFA-BASIC and STOS) here as well, but then on to 68k-assembly and some C. From there onto Linux, which I began using on 68k (the Falcon), and then PowerPC, but now on the boring x86's as everyone else.

It's only in the past 2 or 3 years I've started fiddling with things on the hardware level with Arduino and pure AVR's in the center. Currently I'm messing with a Z80, and Arduino and some memory. More of that in some other post later I think.

I also like collecting older computers, so my ebay account gets some exercise once in a while (far too often :)).

That more or less sums it up I think.

Welcome Stefan - look forward to hearing more about your Z80 project!

Hi, my name is Vic, and I've been addicted to computing since the 1970s... :-)

I'm not sure how much time I'll spend here, but it looks like a fun forum, thanks!

cheers, - vic

As well as a computer addict, Vic is a Forth enthusiast and an embedded-system designer. By email, he & I were discussing a document describing his own particular Forth variant -- what he removed from the model and what he added -- and I was hoping he'd post that here. (Uhh, well not here exactly; I mean over in the Software section!) How about it, Vic? :)
