Commodore obviously used the EPROM adapter and an existing surplus 6530 rather than make more 6530s. But, the 6530s are fully functional, and there may be versions with ROM contents that we do not have. So check the part numbers on the 6530s with adapter boards. wlevak@sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org Message was sent through the cbm-hackers mailing listReceived on 2014-04-15 22:00:07
