Trying to clear out the generation 1 SymDOS I/O Boards. The only difference between generation 1 and 2 is that generation 1 uses a now discontinued microcontroller for TTY to RS-232 communication. These are functionally identical to the newer SymDOS boards.
The SymDOS I/O board is custom I/O board for the SYM-1 single board computer that provides SymDOS functionality which allows for floppy disk access using Commodore IEC disk drives.
- Commodore IEC floppy disk drive, or SD2IEC, access via SymDOS
- TTY over RS-232 communication via a micro-USB connector
- Cassette audio out (jumper configurable HI or LOW) via a mono 3.5mm jack
- Cassette audio in via a mono 3.5mm jack
SymDOS functionality requires SYM-1 Monitor version 1.1 (available for purchase separately) and either RAM at $9000 or a burned EPROM addressable at $9000. I recommend Corsham Tech’s SYM-1/AIM-65 RAM Board.
Includes full color manual, a single dupont jumper cable (color may vary) and USB flash drive with SymDOS software and original manual.
