blimey, you -knew- the designer , ask him why he didnt add video wait states as standard :) still, one 74ls02 later and its there.

i still have my trash 80 in the garage, refuse to throw it away despite the wifes complaints.

think i might ressurect it when my kids get a bit older so i can show em how a real computer works (all that discrete logic and the VSLI! Z80 :).

i had hear summit about THOR, not a lot though, i worked in a tandy approved repair center as my first job, repairing trash 80s from model 1 to 4p.

made some neat gizmos like 8 bit sound I/O with assembler code etc.., gee wish i had patented it :(, would of given the likes of creative a run 4 there money aye.

anyway, thanks for replying.
