Re: [M100] nec- pc-8401 *b*

[Tom Dison]

I think the A and B might refer to what country it was sold in, though it
usually is listed as BM. The guide for the BM mentions 240 AC input, so I
think it might be the UK. Mine is the PC-8401A-LS that has the larger
vertical sized screen so the font isn't squished.

Re: [M100] Cables for my TRS 80 Model 100

[Tom Dison]

I love the GuruModern. Even though I know how to make one via Arduino
myself, it's become unwieldy as separate components wired together (board,
sd-card, etc). I created one with a small LCD that showed the wifi
connection and the current BAUD rate, but it was bulky. Especially for my
NEC PC-8300 and my PC-8401, it's so easy to just attach the GuruModem, and
use the SD card to store frequently used files. I have files for Basic, DOS
and CP/M on it so it's ready for whoever needs it.

Re: [M100] REXCPM orders update

I think I need a new internal battery, so I ordered one and I'll replace
it. Especially now that I have a good RAM backup. In think that's why
memory kept resetting. I just bought this M100 off eBay.

Quick question - in the directions it says install, restart and ensure Rex

63012. That didn't work with this. Is there a similar call statement for
this?

Re: [M100] Off Topic: NEC PC-8500/Starlet

[Tom Dison]

As an owner of a Starlet, I have a 32k cartridge that lets me use the full
64k for CP/M. That's the only change I see.

I also have the expansion cartridge that lets you connect a monitor and a
floppy. I don't have the floppy (yet?), but I do have the monochrome cable
and have connected it to a composite monochrome monitor.

The major mistake they made is to only allow the memory cartridge OR the
expansion cartridge, not both. Of course, if I can every find the floppy
drive then I wouldn't need the RAM cartridge to give 64k to CP/M.

What kind of term/comm program are you including with CP/M?

Re: [M100] Undocumented hardware

Thanks, I’ll keep the changes to myself. I want to add an interface for
simplicity, maybe even a “disk-drive” look to it. I have it on a RPI in a
case with a screen top. I think a full-screen Drive Image with blinking
activity light would be cool.

I have to say I really like LaddieAlpha, I have it running on a Raspberry

Re: [M100] Prepping for CP/M on the Model T

[Tom Dison]

I use RunCpm on Linux. I also just installed in on an Adafruit Grand
Central M4 Express microcontroller. Just connect a micro-USB connector and
use a terminal program like Putty at 9600. It uses a MicroSD card so I can
just copy apps to the SD card.

I don't think so, but you can transfer stuff back and forth with the
term program - I think it is qterm.

As for the font, yup it is a little dubious, but for playing around it
is serviceable.

I put rubber bands on mine in the early 90's because I wanted to take notes

otherwise. Asking the rubber bands was something I have up by myself, I
didn't know others did that too.

I have it running on my NC200, it works well, mostly. I also have a NC100
I'm going to put it on. It has a little better support for the 100 than the
200. Some of the graphical apps only work on the 100.

A serial port normal does supply power, so it does produce a drain.

Re: [M100] Tera Term help

[Tom Dison]

Yeah, I just did that same thing, and added a cheap Null-Modern adapter
in-line and all was good. I keep an set of male-male and female-female
Null-Modern l adapters, plus a bunch of gender adapters around just in
case. So far I've connected M100, Epson PX-8, Cambridge Z88, Amstrad NC200
running CP/M and a bunch of DOS palmtops. The USB serial adapter has lights
for RTS, CTS, TxD, RxD etc. I highly recommend that for troubleshooting. My
hardest was a Poqet PC Plus where I had to build a custom cable from an old
Toshiba External floppy. I connect it to a RPI Zero and surf the modern web
with Links2.

I definitely agree with you, that's what I use my RS232-Wifi for. I've

I also know there is a Plato project, Irata Term (or something like that).

Re: [M100] ebay seller

There is a model 600 for sale at a good price on eBay, but I'm kind of
hesitant. It seems to be quite the oddball model in the series. Does anyone
have experience with it?

Re: [M100] Tandy 200 RAM modules

Check eBay. There is a gentleman who makes them and sells them on Ebay. I
bought 2 earlier this year and they work great.

Re: [M100] Ask a silly question

[Tom Dison]

Don't forget the Video part. Many moons ago I had a DVI with a model 100
and a monochrome monitor. Suddenly you had 80-column text. Combined with
the extra storage of a floppy I felt like I was in heaven.

And where do I find a Rex? I've really been looking but haven't found one.

So I don't need any software installed on my M200 for one of these? I have

Re: [M100] TPDD Utility Disk

[Tom Dison]

I don't believe you can create one with a PC floppy controller. I'd buy a
copy off of someone is I could. For now, I'm planning on using the python
library on Linux box connected to the drive to create the disk. I'd much
rather just have the floppy.
