WTT: My Amiga Mouse for your Atari ST Mouse!

Re: Q-bus I/O project

Quite a piece of work. I hope you can continue to plug away at it. I get that bit about mistakes. Even my simple PIC-based Documation card reader interface board had a mistake (fortunately, one I could easily fix without having to create a new board). Fortunately, my Mark-8 boards ended up

DEC H7140 (11/40) power supply revisions and general advice?

Hey all -- Once again, I find myself in over my head debugging a power supply, this time an H7140 from a PDP-11/44. Here's the skinny: I examined the supply physically before experimenting and found a capacitor on the Bias/Interface board that was leaking, bursting and rather burned-out
