Z80 processors?

ZXNet echo conference «hardware.zx»

From Sergey Cherbynin To All 30 January 2003

Greetings, All! I have a yellow scorpion with SMAK, so the other day I decided to test a couple of processors for performance (I had Z80A and Z80B lying around in my stash), but on my board there is KR1858VM1, when installing these percentages, I can no longer detect screw (as if it was not there at all), but otherwise everything is fine. Who knows what the reason is? All the best, All! Best wishes *** Sergey ***! >>
