    Well no matter what I'd say it needs a replacement.

    The last five are kinda funky to very funky. I'd probably replace that 74ls

    If those readings are from with all chips installed, then I'd say for sure that 74LS needs to be replaced.

    You need all chips in their sockets. This would be potentially caused by the CPU R/W line not being there so it's just floating.

    Awesome, that's exactly what I was looking for, I'd replace that 74LS32.

    Can I see the schematic? You need to trace pin 4, the WE pin, it's got some issues in the write enable circuitry

    I guess it's time to look at replacing chips

    If I were you, I'd socket the RAM chips. Dual wipe I'd go with these https://www.mouser.com/ProductDetail/3M-Electronic-Solutions-Division/4818-3000-CP?qs=IGgAdOvCTsRPXNYrGw8EYA%3D%3D For machine pin I'd go with these...

    Best OS for Kanga?

    Looking at EveryMac it's specific to the G3 apparently.

    Best OS for Kanga?

    I'd upgrade the RAM personally, but it appears it's special. 32MB isn't too much RAM so I'd say 8.5 or 8.6 as well.

    SuperMac Spectrum can’t enable acceleration

    I thought it was just 1.0 that was like that but 1.2 allowed QuickDraw

    SuperMac Spectrum can’t enable acceleration

    Awesome. Thank you. I know the TMS34020 and stuff is actually a CPU so that’s why I got confused. So I’ll have to fix my Radius

    SuperMac Spectrum can’t enable acceleration

    No sockets, I’ve reflowed the card before and no fix
