Re: Electron IC18 & IC17

Re: Faulty Issue 7 upgraded model A beep black screen no cursor

the 555 is where the break key is connected and you say the RST is fine and take it the RST (not) (output of IC33 pin 4) is also okay?
and there is also the RSTA (not) which is used to reset the 6522 VIA ?

Re: Open Source Logic Analyzer Experiments

I end up with a zero byte txt file, guess more playing around is required. No output typically means an issue with clocking. How exactly did you create the capture file? i.e. what signals are connected, and how was it clocked? There are two options for clocking: 1. You capture syncronously (one sam...

Re: Lunar Jetman protection

The last 3 parts are all continues data streams this is 100% perfect copy reproduced from the game (the wav is 31Mb if anyone is interested).
I also have a Lunar Jetman Special Version, it says this version was fixed by Verysoft 1986 on disc.
