Re: [M100] call for programs and games

If you could make room for only one thing in the main rom, would it be a tpdd dos, or xmodem? Remember, tpdd was only one of a few different kinds of disks, it's only a sort of defacto standard now because of various reasons, probably mostly because it works over the serial port and the protocol

You know... thinking about that problem of needing a way to get a dos back if you wipe ram, why can't we have multiple roms? Would it be theoretically possible, assuming some new hardware, to break up the 32k rom address space into smaller seperate chunks, so instead of having to choose ts-dos rom

Re: [M100] Tandy Portable Disk Drive...

The "M100SIG" archive contains a few programs just for dealing with the incompatibility of different dosses. There is at least one or two programs just for loading and unloading the dvi dos and a tpdd dos so you can switch between them without actually wiping and reinstalling each time. > There

Re: [M100] Can't format a disk with DVI

One of mine had that too, (original dvi drive with bad caps underneath) but it also had other problems because replacing those caps and replacing the corroded traces with jumper wire didn't fix it. It lights up at the right times and the dvi detects the door open/close, but the motor runs too

Re: [M100] batteries...

nimh chemistry is ok for the circuit, but there is always still the separate issue that the cheapest no-name manufactured ones are a risk simply because of unknown construction quality and longevity. So, try to get Yausa or Varta or Panasonic etc, and generally pay more than $5 per batt not $2

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

Ah! These are good, thank you! Already I can see why you have no twists. I won't be able to show you what I mean for a little while but I have pictures of at least 5 or 6 different manufactures of dip40 idc connector (the blue one in your pics) and I can show how the pins on yours are different

Re: [M100] 8K RAM Chip

There are at least a few different "build your own ram upgrade" articles on club100 and other archives of old forum posts, and in magazines too I think but those are hard to search. Here's one that is not one of the old original ones I was thinking of, but looks ok.

Plus when you search for the original part number or generic size code, you get nimh batteries that claim to be drop-in replacements for the size/form/terminals code. They can't know the details of every possible circuit the original parts were used in, and yet they feel safe saying that the new

I meant to say, the only harm it does is, it harms the next owner, in that they may or may not like the idea that their M100 has been modified in this way.​ It's arguable both ways though. You could say that by removing the battery, you are removing all possibility of it leaking an corroding the
