Today I only had time for few things:
Rom port, sockets for buffers, and floppy mod, 16mhz osc, dac and the other 3 smd ics, simm socket, few jumpers.

Yes waiting on snail mail and our post is not fast in the best of times. I must say exxos mail comes from the UK to the west cost of Canada in about 3 days

Hmm not what I expected, seems like troubleshooting times. I got white screen & no other output (on serial and such) and the DAC runs really hot. Can't keep my finger on it after 10-20 sec. Connections seem to be ok, though.
I took it off, put back on, no change. might be faulty?
I think the mono switch should work because if I switch the jumper the output goes black.

Got the DAC from @exxos so not sure what's your exeperience with this batch?

Using the diag rom at the moment but same with test cart.
