b00tdisk: well my guess is that theese chips and the cubo chips etc came all from the same place , and that was just after commodore went bust.
dont know how many cubo's was made nor access cards , but my guess is that there is more than 1 version of the access.
like cubo cd32 , it have 4 diffrent versions..
(1 extremly simmilar to the cd32 , 1 with 030 , 1 with fastmem onboard etc...)
