After a couple rounds of final tweaks by myself and Nate Lawson, I’ve released the ZoomFloppy PCB to production. The board has been designed to fit inside a standard Hammond 1591XX Black ‘S’ or Translucent ‘TBU’ case. In addition to the normal IEC connector and the Mini USB Type ‘B’ connector, you’ll find a number of additional connection options:
- A DB-15 “Parallel” socket. This uses the defacto standard pin mappings
- A 2×8 Header. This uses RapiDOS/ProfessionalDOS pin mappings
- 2×20 Debug Header. This provides access to each pin of the interface and was designed to allow use of industry standard IDE cables
- 2×12 IEEE-488 Header. Since the IEEE-488 Centronics connector can be hard to source and expensive, this connector offers a much cheaper alternative.
- IEEE-488 24 pin Centronics connector. The industry standard GPIB/HPIB/IEEE-488 connector.
- User Port Edge Connector. This allows the use of older parallel drive cables that assume a connection to the C64 user port.
Only the Mini USB, IEC, and DB-15 connectors will be populated standard. The IEEE-488 connectors will be stocked when ZoomFloppy adds IEEE drive support, though they will be optional.
