the difference that is no difference makes no difference
It’s summer here, and I was trying to think up interesting projects I could do with my son over the xmas period, and one idea was to put together a Dick Smith Funvision on a breadboard. Before you get too excited, this project was more about the process of making a computer, rather than trying […]
For the past few months I’ve had two Acorn Electron’s. One is a fully working one I bought from the UK earlier in 2015. The other is my brother’s one which was broken. I thought I would attempt to fix it … but all I’ve confirmed is that it has a very dead ULA. Spare […]
So I’ve been busy lately making some homebrew microprocessor systems. When you make a system from scratch you have to figure out how to get it to boot some code. There is no built in flash or ISP mode in these old school microprocessors, so you need to figure out how to get some code […]
I’ve added yet another room cluttering object to the office; an Atari 520STFM. The ST was always ‘the other one’ in the 16 bit era that the Amiga tended to dominate. Both the ST and the Amiga had a similar speed 68000 CPU, similar amounts of RAM, but big differences when it came to the […]
So I am quite enjoying playing around on my new C64. Loading stuff onto it is either by using uno2iec or using real floppies. uno2iec has the major convenience of ‘you just need an arduino and some wires’, but you still need a real PC (or rPi) attached. There’s also limitations to what uno2iec can […]
So I’ve finally got the ZXMore together. Here it is with all chips in, and just about to start doing the SMD tactile switches for the keyboard;
So, next in my long list of computers I wanted but never could afford as a kid is the Commodore 64. I can’t quite remember how much they cost in the early 80s in Australia. Definitely in the $300 or $400 region early on … and this was at a time when I could barely […]
I spend a bit of time looking at ebay.co.uk in the ‘Vintage’ computer sections. The UK was really the centre of interesting 80s home computers … so there is a lot of variety. However I recently came across www.sellmyretro.com which is an auction site purely for the retro computing community. Not only are their old […]
So not only did I retrieve a 5 1/4″ floppy drive from my parents recently, but I also grabbed the family Colecovision and my brothers old Acorn Electron. Since this was all fitting in my luggage going from Australia to NZ, the Colecovision was mostly disassembled to bring back. In fact I only bought back […]
So, all Amigas came with 3 1/2″ floppy drives back in the 1980s/90s. Initially when the Amiga 1000 came out 3 1/2″ diskettes were quite expensive compared to the then older 5 1/4″ diskettes. I had two older brothers with Amiga 1000’s, and I later bought my A500 in 1988. Given that we were all […]
