Does anyone have a copy of the DEC VT125 Maintenance
print sheet set?
The mp sheets are DEC part number #MP-01053-00
These should hopefully be slightly easier to find than the VK100 MP
sheets.
These are needed for repairing a VK100 and for a project
reverse-engineering how the hardware worked, since it turns out the
VT125 uses an almost but not exactly identical state machine "engine"
for drawing vectors to the VK100. This VT125 information should be
extrapolatable to the VK100 hardware which preceded it.
The Tech manual for the VT125 is on bitsavers as part of the VT100
Tech manual revision 3 (
http://www.bitsavers.org/pdf/dec/terminal/vt100/EK-VT100-TM-003_VT100_Techn…
starting on page 6-70, pdf page 316)
I'd be more than willing to scan (at high quality) or photocopy the MP
sheets if anyone has a copy they could lend me. A good quality 11x17
1:1 photocopy of the originals is better than nothing, as long as the
tiny labels on the schematics are still readable. (If all you have is
a poor photocopy, though, let me know! A poor copy is better than no
copy at all!)
I am fine paying for shipping, handling, finding/digging out of a
pile, etc.
P.S. Does anyone have a VT125 and the means to dump the three code
roms on it? I'd love to get my hands on a copy of those as well.
P.P.S. Does anyone have a VT125 and a desoldering station/know-how to
remove and dump the ?five? proms on it? They're not immediately
necessary but it would be convenient to have copies of their data for
the future and to help with potential repairs.
P.P.P.S. If anyone has a not-installed VT100->VT125 upgrade kit which
they are willing to sell, let me know off-list.
