John Bell Engineering was a small firm producing microprocessor many boards between 1980 and 1990.
The early boards were 6502 and Z80 SBC’s, later boards were for the Apple II, and the last ones for the IBM PC bus.
I present here, what I have found, of John Bell 6502, Z80 and Apple ][ boards.
- John Bell PN 80-153
- John Bell PN 81-260
- John Bell PN 82-300
- John Bell PN 80-Z80
- John Bell Apple 6522 card
- John Bell Apple 16 bit A/D
- John Bell Apple Cards
