Hi.
Are there any equivalent, Direct replacement ICs for the SDX FDCs
MB8877A DIP40
WD9216 DIP8
Are any of these pin/hardware compatible WD1772/WD1770/uPD765 etc ?
If so give my a list of direct replacement FDC ICs and I'll keep a lookout for them on my travels !

Hi Lez,
FDX Used a 1791
The original SDX Used the MB8877A
The "new" SDX Used a 1793
The MB8877A is compatible with the 1791-02 and 1793-02, so should do all Memotech disk controllers
The earlier controllers user the FD9216 data separator
The "new" SDX used UM8326B which should be compatible with all controllers
regards
Dave
