Not close, exact. The 'MODEL TK02 80 COLUMN MONOCHROME CARD' has: UM 6845 8440 , TMM2016BP-10 , TMS2764JL-45 , a 10Mhz oscillator (may be 16 or 18 - can't quite read it and havn't put a 'scope on it yet) and fifteen 74LSxxx chips. Absolutely none but I'm not looking further than getting an OS at the moment - if it then doesn't work however, I'll remember your kind offer. John Honniball asked about the disks in the Einstein - having now taken them out of the steel box sleeve which every 3.0" drive seems to come in I can report that they are different to the Amstrad PCW8256/8512 drives - whereas the Amstrad are the 'infamous slack belt' drives, the drives in my Einstein are Teac direct drive (hurray!).
