Yeah, I guess I'm getting it confused with the 1620. The
1130 and 1800 are supposed to be mostly the same, and the
1800 is definitely SLT. Well, that may be a real challenge,
then. SLT is simple logic, but the art of chip passivation
was not totally figured out back then, and so the chips
degraded from moisture and oxygen exposure. Do you have any
idea what shape the CPU is in? Have you powered it on?
