In one of my 1050's I found a green PCB with on it a 6502 CPU and a 6264 RAM chip.
I guess this is some kind of Happy print, where the 6264 is a track buffer and the 6502 is a replacement of the 6507.
On the PCB is also an eprom and a few TTL. I can not identify the TTL's since the creator of this card scratched of the numbers on it.
On the print i read Copy Card 7.0
Somewhere it does ring a bell... I believe it is a 'special' version of the Happy, but I'm not sure.
Strange enough it appears to be very incompatible with the HS routine, since both the BlackBox and the IDE+ do not want to boot this 1050 on High Speed with it (I get an error).
