Okay - my tools order should get to me on Monday the 25th. I still haven't gotten TS-DOS sorted out on my 102 but I'll play with that this weekend.
Looking forward to building a few REX units! I'll post any QA issues I encounter in the instructions and also document my M100 load procedure in detail. -Josh On Thu, Sep 21, 2017 at 9:31 AM, Brian White <[email protected]> wrote: > I just recently made a digikey cart for quad too, but the memory chip I > picked is not yet proven.
