Brian, that DVI Wiki is awesome, thank you. I've ordered some
gender-changer male pin headers, so next weekend I should have a working
102 setup.
On a side note, LCD on the 100 that came with the DVI has started
flickering and dimming, but the computer itself has also started crashing,
after using
Thanks everyone. Think I'll take Mike's advice and just mark them. I was toying with the idea of using only one but there really isn't a good reason to do so.

Ubdervolting draws more current, which may be stressing some part even if
it still works.
Both under and over voltage are bad for different reasons.
The only spec that you can exceed harmlessly is a ps that can deliver more
current (not voltage) than needed is harmless.
A ps that can't deliver e

Hi Frank,
Any chance you'd share the PCB files for your RAM modules so we can build some?

I think it would depend on the adapter type; I would measure the *actual*
voltage of both adapters, both unplugged and plugged in with the computer
turned on.
They do have regulators, in fact they have complete regulated switching power
supplies. I really wouldn't recommend using the 8.5V suppl

I've used both and it's all good. We just have to remember that the
polarity is negative center, unlike most electronics, when we use strange
power supplies.

The 102 (only tech ref I have handy - see p. 30) uses a DC-DC
converter to regulate the 5v supply. I'm not good enough with power
circuits to guess what the maximum safe input voltage is, but I'll bet
8.5 is fine.

Interesting; yeah, that's what I thought it had to be to explain what's
happening. Here's what I think:
The 'long' cable is probably the standard M100>DVI cable that came with the
DVI, and it would presumably work if you plugged it into the M100.
The short M100 cable is probably a home-made sho
That's a possibility, but as far as I can tell no combination of what Chris has

or just go to your local dollar store and pick up a 3.6V portable phone
battery; it'll be a little larger but last longer.

I've used rechargeable NiMH (Eneloops) in 8201a packs
for many years. In practice, I have'nt noticed a downside
to plug-in cells, & there is one distinct advantage - It allows
use of a purpose-built Eneloop charger (Maha C9000).

A quick power question for those who may be able to answer this question. On
my NEC 8201 the AC power adapter is rated for 8.5 volts. The AC power adapter
for my 100/102/200/TPDD2 is 6v. I have both on my desk but get them mixed up at
times even though I try not to. The units seem happy with ei
I thought we'd discussed this to death a few months ago...
I don't know where this idea of a third cable comes from; when I bought my DVI
brand new many years ago it came with two cables just as the insert shows, one
with a 40-pin DIP Plug at the computer end for the M100, and another with a

Probably someone ends up with 3 cables because probably a single long,
100-only cable (and a 100-only system disk) came with the DVI, and the two
short ones came later with the 100/200 system disk.

None have any twisted pairs - both the long cable and two short cables that
connect together are straight through.
Interesting trivia - found a resume on a disk that came with it -
apparently this unit belonged to a Radio Shack store manager in OH in the
mid 80s :)
Let me know if you guys need me
Can anyone please recommend a source for the correct internal backup battery
for the M100? I want to be sure I purchase the correct one.
Thanks,

There is a single sheet insert that came with one of my DVI manuals that
shows a two-part cable, where I think the deal is there's really 3 total
parts, one for 100, one for 102 & 200, and one for the DVI.
I scanned it and uploaded it to Archive.org a few weeks ago. It's a little
