[WTB] EF68B09EP/MC68B09EP

Hi,

I'm looking for microprocessor:  EP68B09EP  or  MC68B09EP

Preferably NOS in quantities of about 50 pieces.

I don't know how many he has left but I bought three MC68B09EP (the version where Q/E pins are inputs) that either free-run or actually run code (ASSIST09 monitor @1.75MHz Q/E clock speed).

He doesn't ship to Europe.
The chip doesn't look original either, rather sanded and then  laser remarking.

Maybe look at the Hitachi HD6309

Ebay search : hd6309 hitachi

Should be MC6809 compatible
