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. Generation 1 boards DO NOT require a Teensy 4.0 for TTY to RS-232 communication, they have a preinstalled Teensy 3.2.

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.

Features

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

TTY over RS-232 communication requires an installed Teensy 4.0 microcontroller.

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.

Absolutely a must for the SYM Tinkerer!

I absolutely LOVE this board! With it, I've been able to dump all my coworkers old cassettes to disk, as well as load on basic, the rae, his forth interpreter, and so much more!
Very easy to put together, the surface mount resistors are big enough for even a novice like me to solder on.
A+ for the variety of ways you're able to load SYMDOS on to the SYM, as well.

Whenever an issue arose, the seller was all too happy to help me troubleshoot.
