A personal collection of programmable retro computers, largely from the 1980s and 1990s, along with some bits of code.
Most of the computers are from the 1980s when I started coding, mainly Sinclair and Acorn BBC machines. I've also collected more from the 1990s, mainly Psion Organisers, some of which I used quite a bit in their day, and others which I would have liked to own at the time.
While not an electronics engineer, I will have a go at mending many things and have had some success with BBC Model B and Master 128 and have brought a lot of Psion Series 3 organisers back to life too. You'll find some theres adventures in the Blog, and on Twitter.
Still to be added are my Psion Organiser II, another couple of Sharp handhelds, two Casio computers and my Acorns: Electron, BBC Model B and Master 128, as well as few peripherals and a reasonable collection of books.
The Texas Instruments TI-99/4A followed the TI99/4, which was let down by a poor keyboard, and was released in 1981. Based on the TMS9900 microprocessor, the TI99/4 was the first 16-bit home computer.
