Hi all,

i need urgently a service manual of the EX-8000. I have problems with
the SRAMS located nearly thh NEC-CPU (i believe they are numbered
with 74S189).

They work, but they all (8 pieces) get after a while rellay hot (they
also work but while they are getting hot they affect the resonance).
But the voltages and microamperes on their Pins are correct so i
believe they are accessed/clocked too fast. In first order i need the
voltages of the power supply (brown/yellow cables) and the frequency
on the "TP-clock"-Pin.

Thanks

Stef
