Sorry 'bout that ;(
Yeah, I've wished for a time machine myself a few times recently; been kicking myself
as well
over some of the stuff I've tossed.

Three more books available:
RS TRS-80 Color Computer Technical Reference Manual 26-3193, 69 pages
RS TRS-80 MC-10 Micro Color Computer Service Manual 26-3011, 47 pages
(Photocopy purchased from RS)
MOS Technology MCS6500 Microcomputer Family Programming Manual, Jan '76,
8 1/2x11, approx. 200 pages. Will throw in Synertek 6500 & 6500B data
sheets full of timing and cycle time info so you can join the
fascinating (!) discussion presently raging among Dick, Allison & Ben.
Sure now you tell me 10 years I last had a COCO. You would not believeb
the old computers I have thrown out do to 1) lack of software. 2) lack
of docs when they break. Mind you most of the computers have been $10
specials but they would have been nice to keep. Also a lot of data-books
and old byte and kilabaud magazines that I would have liked to keep got
too wet in storage.
The 6809 is the cleanest cpu for opcodes and for timing too. And to add
to the chaos the
FPGA cpu's I am building have even another variation in memory access -
a 6809 style access with good setup and hold characteristics.
