Title: Joust - Replacement for a 4164 RAM
Post by: ckong on July 10, 2017, 08:30:51 PM

Guys, my Joust gives a Ram error 34, and a Ram error 38 when I swap Ram 34 with 38 (So defintely a faulty RAM). The game has been modified in the past to use 4164 RAM and now I need one or a few (spare) 4164 rams. The present ram is TMS4164-15NL, 150ns. Question: can I just use any 4164 replacement RAM or does it have to be 150ns etc.?

Thanks.
