Sold [US] Expansion boards for Netronics ELF II Computer
« on: July 15, 2019, 08:26:30 pm »
Boards are free.  Available for shipping costs only.  For fans of the vintage RCA 1802 processor.  Three boards available.  Unfortunately the ELF II is long gone.

1.  4 kbyte memory expansion board.  Worked when last used several decades ago.  7805 regulator clearly has broken pin from storage.
2.  Digital I/O board.  Parallel and serial interface.  Again worked when last used, but shows storage wear.  One capacitor attached via 1 lead only and evidence that flux was not cleaned on this board.
3.  Color Music board.  Don't remember if the video section was ever used.  Appears intact except for missing speaker (similar to standard speaker in transistor radios of the era.

These have no real use except for nostalgia or reconstructing history.  From the days when it took 32 chips to make 1 kbyte.  They will be tossed if no one has an interest in them.
