[M100] Model 100 Backup Battery Replacement

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, Paul Paul

Re: [M100] DVI cable for 102

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

Re: [M100] DVI cable for 102

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 paper about the

[M100] Power Adapter Questions

 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

Re: [M100] DVI cable for 102

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

Re: [M100] Power Adapter Questions

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

Re: [M100] DVI cable for 102

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. On Fri, Mar 16, 2018, 6:57 AM Chris Kmiec wrote: > None have any twisted pairs

Re: [M100] Power Adapter Questions

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. On Fri, Mar 16, 2018 at 12:19 PM, John Gardner wrote: > I've

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. On Fri, Mar 16, 2018 at 11:32 AM, Josh Malone wrote: > The 102 (only tech ref I have handy - see p. 30) uses a

Re: [M100] Power Adapter Questions

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). ... On 3/16/18, Kurt McCullum

Re: [M100] DVI cable for 102

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

Re: [M100] Power Adapter Questions

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

Re: [M100] DVI cable for 102

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
