Re: [M100] Talking over serial port
1. The two can talk to each other if that's what you mean. If you try and dump a text file to the m100 you can lose stuff if the baud rate is too high. I've logged into a raspberry pi from my m100 but I don't know how a mac reacts to logging in from a serial terminal. I did command line stuff, like ls and shutdown things. Didn't try anything fancy because I didn't have the right termcap but it's out there.2. Going the other way, I've never heard of anyone running their m100 from another computer. CPM??Sent from Samsung tablet Original message From: Will Senn Date: 10/6/22 20:21 (GMT+01:00) To: Model 100 Discussion Subject: [M100] Talking over serial port I have TEENY.CO working on my M100 and DLPlus on the Mac side of things and they work great. I plan to use it for all of my file transfer needs. However, now that I have the cadillac version running, I want to try more crude (cerca 1983) methods. In particular, I want to try using TELCOM. If the former works, should TELCOM work over the same physical configuration? i.e. M100->DB25-DB9 (NULL MODEM)->SerialUSB->Mac.I've got a couple more questions, too...1. What kind of connection can I have with the remote system? I mean, can I log in and run commands? (I've done serial and TTL on my BeagleBone and Raspi systems)...2. Can I run M100 stuff from my remote?Thanks,Will
Re: [M100] QWERTZ ROM for T102

Then I copied the ROM to REX to try similar what is written in the installationdescription, loading QWERTZU ROM from REX is ok and can be enabled by a CALL63012, but followingthe further instruction to run another ROM fails. Have you any idea how to get the above working, means installing QWERTZU ROMand run i.e. MULTIPLAN from REX? I´ve attached ROM dump and installation instruction for you reference.

Re: [M100] Modifying TELCOM
I know this is off topic but which Psion do you have?

I just pulled out the parts from the TELCOM entry point to the next entry point. I’ve been going through it and replacing addresses with labels, such that it can be compiled run in high memory. I haven’t spent much time with it lately, got hooked on the Psion Organiser and that’s been eating all my hobby time. Neat little machine, kind of the Model T of handheld computers. —mark
Re: [M100] Model 100 Scientific Case ?
Back in the 80's I used a model 100 to field program data loggers made by Campbell Scientific.

Re: [M100] An article about the TRS 80 Model 100
Hello, It was that article that got me to dig out my M100 and a 'spare' raspberry pi (a B+) I had sitting around. I had played with the m100 and the first pi I had but that project fell by the wayside. I connect in a slightly different way since I had been connecting the pi to my other machines via the GPIO bus and a USB to serial adapter. So (to me) it seemed logical to try the M100 and the GPIO bus. This meant using a level shifter (the pi is 0/3.3 v, I think) and RS-232 is -12/+12. I found a couple of pi sites that talked about the MAX232 chip, and I built a little adapter using this chip from a kit. The pi and the M100 work fairly well together. There is no hardware handshaking, but at least raspbian and a recent version of arch both had xon/xoff handshaking as default on /dev/ttyAMA0 (the GPIO bus serial port). At 19200 baud things still got garbled but 9600 is just fine. I made my own null modem with some db9 and db25 connectors and a soldering iron. I even compiled dl (the linux version of desklink) and I can use the pi as a mass storage device. I still haven't figured out how to end the dl program from the M100, but the pi is fairly robust and with another pi (my 3g modem/wifi hotspot) we just unplug it when we want to turn it off. I could probably also use a timer to automatically end dl after a fixed time but I haven't gotten around to trying this.

Re: [M100] An article about the TRS 80 Model 100
Hello, I had the dlplus.zip lying around for a long time, but I see that it is at the bitchin100.com web site (DLPlus for Linux etc.). I'll try and do some proper documentation for this and a web page but the short version (from memory) is The Sparkfun converter seems to let the M100 talk to the pi but it can't convert the ttl signal to RS232. I gave up on that one... The converter I have with the Max232 works OK and I have the pdf for it but the web address on the pdf (www.anykits.com) doesn't work anymore. I thought I bought it from electrokit.com in Sweden but they don't seem to list it now, either. Googling Raspberry Pi and Max232 gives a lot of results that look promising. Some look like they plug right into the GPIO connector. There are only 4 wires connecting the pi (GPIO connecter) to my level converter. I used an old CD-ROM audio cable and moved some pins around. You need tx,rx,gnd, and 5v. The level converter gets its power from the pi. No hardware handshaking. I tested it both with arch and raspbian but raspbian had a C compiler etc. so I stuck with it (Jessie). You need to configure Raspbian to start in command line mode, and while you're at it, edit the file in cmdline.txt (in boot) so that the baud rate after ttyAMA0 is 9600 (default is 115200). With a null modem between the level converter and the m100, it should work at 9600 baud. Xon/xoff seems to be the default for ttyAMA0. Unzip dlplus.zip somewhere and type make. I don't think I changed anything in the source. dl seems to set the baud rate for the transfer to 19200 (I can see it in the source) so I've set TINY to 19200 for transfers. I've been meaning to change everything to 9600 but I haven't gotten around to it.
