Parallelport Adapter U4 for Switchless 8x Multi-Floppy Speeder with 32KB/512KB RAM Expansion for the Commodore C128 DCR
The Parallel Port Adapter is a addon for the 8x Multi-Floppy-Speeder 32KB/512KB RAM Expansion for the C128CDR. The Parallel Port Adapter Board replaces the CIA2 6526 (U4) on the C128DCR motherboard. The CIA 6526 is then placed into the 40-pin DIP socket on the adapter board. This adapter replaces the user port’s board connector, which is usually used, leaving the user port of the C128DCR externally accessible and eliminating the need for an external parallel cable. The Parallel Port Adapter Board includes a 10-pin ribbon cable that must be connected to the Multi-Speeder Board. This adapter board and cable are only required if the 1571 floppy drive is to be operated in parallel port mode with DolphinDOS 3.
