to Dieter and to Anyone who could help---

I replaced the blown S-80C32 with the P80C32SBAA but nothing has
changed...
if the two microcontrollers are compatible (i think they are more or
less the same...) what else can be the problem the EPROM with the
firmware in this case, is it possible to re-program the EPROM or to
obtain a new EPROM for the A190

TIA

Antonio
