Re: Microscopic chip analysis

Oh wow, this explains how the current state of emulators and fpga-implementations is as good as they are. I guess that eventually, all secrets will be uncovered this way. If smaller fpgas become available, drop-in replacements of the chips might even be possible but I guess it will always be more ex...

Microscopic chip analysis

I saw this tweet today: https://twitter.com/martinlukasek/status/1064983451915485191 The GDG is the Sharp MZ-800's equivalent of the ST's glue/mmu/shifter (don't know exactly the mixture) I wondered if this technique could help us get less dependent on original custom chips from Atari...

Re: Tip restorer testing

Funny, all I ever use is a damp sponge every time I solder, and the iron tip is always clean as a whistle, with no oxidisation.

Re: Tip restorer testing

Re: So need to get one of these...
