Like the BBC Micro, it runs a 6502-based processor but at half the clock speed. AppleĪ compact version of Apple’s famous Apple II line of computers, originally released in 1984. I haven’t needed to modify or repair it at all except to re-seat the ULA which had come loose. I also have an ElkSD128 installed in the back which gives a whopping 128KB RAM upgrade, a joystick adapter, and an SD card interface. This is a cut-down version of a BBC Micro B with a much slower memory bus and most separate chips consolidated into a single ULA chip with only one-voice sound and no Teletext mode, originally released in 1984. The game still works beautifully, and I imagine it is quite valuable now on account of the ROM chip. I also have the ROM chip for the amazingly complex (for the time and system) game Dr. Who and the Mines of Terror, as well as the disks and the rest of the original packaging. I also have a joystick adapter installed in the back. I believe the previous owner had recapped the board already. This has not needed modification or repair beyond the SD2BBC ROM installation and adjusting the potentiometer for the speaker to not be so deafeningly loud.

There is also some interWORD software installed via ROM that I haven’t messed with much. I also have a BBC-branded Watson disk drive and an SD2BBC installed. It features a blazing-fast 2MHz 6502 processor and 32KB of RAM.
This is the most popular variant of the BBC Micro, a computer first released in 1982. The system works well but I’d still like to perform more modifications to reduce screen noise and improve functionality. I also bypassed the RF output and installed a wire to produce composite output over the RF jack. Because I couldn’t locate a power cable that fit, I removed the 9v voltage regulator circuit and installed a new 5v power socket that supplies power directly to the main logic board. This rare precursor to the BBC Micro was released in 1980, with the same 6502 processor, but a simpler video chip (the same as the Dragon 32 and other early micros).

Portable devices, specifically Game Boys, Game Gears and Atari Lynxes.Apple ][ Europlus (and other Apple II models and hardware).If you have one you’re willing to sell/donate to me, please get in touch ( me at this domain). I am still actively looking for the following items (in rough order of priority). I will be adding an Acorn A410/1 and a Panasonic MSX2 machine at some point in the coming months. I also pursue projects writing games and software for a wide variety of these machines.

I maintain these machines and upgrade them to use modern storage solutions.
I am a collector of old computers, particularly those used in the home in the 1980s and early 1990s.
