the difference that is no difference makes no difference
So I was pretty chuffed with setting up my Frankenstrad using just a CPC-464 motherboard and a homebrew keyboard. However, as luck would have it, a few weeks later, the local auction site had a couple of real CPC-464’s for sale … so I bought one.
So I bought the motherboard out of an Amstrad CPC-464. This was like my Oric Atmos rationalisation . It’s cheaper to just buy the motherboard of some of these old computers, rather than the whole computer (especially when I add in postage from the UK to NZ). And I am more into these old computers […]
So, I have a SIO2Arduino setup hooked up to my Atari 800XL as a virtual floppy drive image thingee. It works pretty well and was really easy to make; one Arduino Uno plus one Arduino SD card adapter plus a few wires. Another popular one is SIO2SD. You can buy prebuilt SIO2SDs from Lotharek , […]
So I ended up buying an Oric Atmos motherboard on ebay.co.uk. I don’t have an Oric Atmos to repair. I somehow rationalised this as ‘this is cheaper than buying a whole Oric’. Of course a key problem with buying an Oric motherboard is ; “There is no keyboard”
Ages ago I read this shmups post about hooking up a Raspberry Pi to an GBS-8200 to ‘get better control of the Gonbes’. I remember trying it. Had a bunch of problems … kind of got it working .. . and kinda concluded it was too much hassle, but had enormous potential. To me the […]
I have a Willem parallel EPROM programmer (or clone). I bought it when I was trying to burn Amiga Kickstarts, but I’ve used it for burning 27C256’s and 27C512’s as well. I’ve had a lot of weird problems with the Willem. Sometimes it ‘just works’. Other times you tear your hair out trying to figure […]
So as well as my C128, I recently picked up an Acorn RiscPC. This is my first Acorn ARM machine (I’m politely ignoring all the phones and other modern ARM chip licensed devices everyone typically has). I’d been on the lookout for an old A3000, but they are so rare these days. But the RiscPC […]
So I succumbed again, and bought a Commodore 128 off the local auction site. It was very yellow, advertised as ‘untested’, but came with a power supply. I bought it more for curiosity. I know most C128’s were simply used as C64s … and well .. I already have a C64C.
OK, the Funvision was fun to do on a breadboard, but I thought I’d have a go at a Colecovision. From my distorted view of the early 80s, it’s similar to the Funvision (same video and sound chips), but actually has a lot more chips than the Funvision. More importantly it has a lot more […]
So I seem to be a bit obsessed with trying to get nice component video out of my recreated Funvision. I thought I might be happy just getting black and white working, but component video output is an interesting puzzle. Poking around the net you can find an op-amp based colecovision component mod and an […]
