Absolutely a must for the SYM Tinkerer!
For SymDOS I/O board for SYM-1 SBC
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.
