Are 7489 ram and 74S189 ram the same thing?
I noticed in the Qbert manual that this is referenced as 7489 for G13, G14 and G15 and as 74S189 for H1-H4. Are these different RAMs? I called my parts souce and they only had 7489 and they did not know if they are the same thing. Seems like they are both 64 bit rams.
Thanks.
