Re: Problems with/after ROM replacement, vDrive and Exapanderam

Thanks Derek, will fix Minerva and put the resistors on the top of 8302 - hope that will solve the problems. Hi, just to add my five cents as I am the perpertrator of the aforementioned mods.

Re: Iss. 5 resurrected, but flickering/freezing

That is an excellent Idea. I checked the connector and solders, they are solid. But then it dawned on me to recheck the voltages and all sorts of fun was happening on the 12V rail. In the end it was my silly idea to socket the 1488, in orderr to redo a "clean" spider mod on the ULA, that w...

Iss. 5 resurrected, but flickering/freezing

P.S. I also replaced all the capacitors...

Re: Microdrive spinning ad infinitum...

Thank you, Derek and everyone else, for your valuable input. In the end it was me again - I actually switched GAL's 1 & 2 :shock:

Now I REALLY need to find me a working IDE device. Got a DOM inbound from China, but that's weeks away...
