Failing that, I could probably detour after the show. Once mbi I have them, they can come to the Les...

Re: BBC Model B takes up smoking

The caps are quite easy to replace, even with just a soldering iron, but disassembly and reassembly of the PSU can be a little fiddly. The worst thing about the popped caps and continued use is that it will add a new aroma that you may not want your beeb to have - quite distinctive. [looks for the s...

Re: A new Warlords emulator for the beeb (was Writing a ...)

The point of this is that you don't have to modify the joystick. In an Atari joystick, at the plug end, you have a wire for each direction and fire, which are all floating unles you press then, then they connect to a single common ground. There is an adapter with many resistors and transistors on it...

I've been thinking about ways to connect atari joysticks to the beeb and think I may have a simple(ish) solution. My cunning plan is to use a 74LS139 dual 2 to 4 line decoder to convert the on/off of the up/down into four bits where only one can be on, the fire button connects as usual. I don't know...
