My 8041A/8641A/8741A data sheet says
"interchangeable ROM and EPROM Versions", "Single
5V Supply" and "Vdd (Power): 5V during normal
operation".
I'm pretty sure I've read 8741s without any 25V
supply; AFAIK Verify mode is not the same as Read
('normal') mode.

I was an Intel salesman and have this board...I have lots of docs,
serial monitor, chess PROMs but no keyboard monitors. Do you have
the BIN files for them to fit in 2716s? I can scan, copy eproms,
anything to help you if you can help me. Thanks, Dave

These docs would be great to have then archived...

WikiP under the "PDP-10" subject claims that Don Daglow wrote the first
computer baseball game in 1971.
I don't think that this is accurate; do any old CDC-ers out there
remember the BAT PP program on every CE's MACE deadstart tape? I
believe that it preceded Daglow's game by a couple of year

Like what? Like most people on this list, I'm far enough away that I can't
just drive over (especially on such little notice), but if there's something
good there, perhaps a local DEC collector can help, or I could pay someone to
go get it. B
I followed up with Cindy and got more info:
"Sperry mainframe? Size of washing machine" is blue and has never been turned
on (no more info but if you are interested she may be able to get a part number)

Dec Station
Dec mate 200
Several small Dec systems the size of 486 desk tops
She mentioned some DEC cables. Very thick with 15 pin connectors. Not very
helpful I know but if it's close to what someone is looking for you may be able
to get more info from her directly.

The Intel AFN-00188B Datasheets for 8041A/8741A specify that EA max is
24.5V. The verify mode for "PROM/ROM" holds EA high at 23V.
The 8048/8748 Datasheets say EA is 32V for 8748 Verify but need only be
+12V for 8048.

Thank you for looking that up. I have several different 8041 and 8041A
datasheets, but apparently no

No rubber. The tapes got stuck to the read-/write head.
