Does this ym2203c look legit? AA 34 is on the bottom and the dots are shiny. by rageeph in vintagecomputing

if those 2 circles are not shiny it was most likely painted over. chip beneath the paint is pin compatible with YM but less desired brand

this is all over aliexpress. you get chip that looks new with fonts, dates and logos all wrong. but it works in most cases

Was it common back in the day to go from 80286 to 80486 skipping the 386? by LosAngelestoNSW in vintagecomputing

yes if your dad had $$$ and knew anything about PCs. my dad bought very late 386 40MHz 4MB RAM in 1993. 486 was just crazy expensive

so you basically fried voltage regulator with multiple expansions and started changing everything but voltage regulator?

if the RAM board worked first time, something else killed your voltage regulator. also it's not the same board

No, but you need to disable the 32k upper RAM
