The attached file will generate TSLOAD. Quite a small Basic program that loads the file into memory, the .do file can be deleted after loading.

Re: [M100] Ultimate Rom II TS-Dos
I don't have TS-Load but here is a DO file that will load it into ram. It's large, but once loaded you can delete the DO file and TS-DOS will be in RAM ready to use. This is one of the three loaders I put together for mComm.

Re: [M100] REX + Ultrascreen100
Oh wow, thanks for making me aware of this thing. Ultrascreen100 is really neat! I'm not quite sure how to turn it back off, though. I'm not sure where Rexmanager loads, but the USC zip seems to have a program "LOADER.BA" for generating the CO at a different load address. Maybe it would be possible to move it out of Rexmanager's way? I don't have my REX (yet! It's coming!) so I can't test this, but I think maybe regenerating the CO to be somewhere other than 60171 might help, if rexmanager lives in an overlapping region.

Re: [M100] Tweaking the space bar
So it turns out the left side catch is missing. There seem to be two holes where the catch was mounted, does it sound rational to perhaps tie the metal bar down with a little piece of wire through those, as a kind of substitute catch? I'm lucky that this is purely aesthetic. The space bar actually works really well. > On Mar 5, 2020, at 12:39 PM, Josh Malone wrote: > > > Possibly the metal bar under the space bar is bent, or one of the plastic > catches is broken.

Re: [M100] Ultimate Rom II TS-Dos
You need DOS100.CO which is about 6k in size. UR-II loads it from your TPDD device (Original floppy disk, or emulator such as mComm, Laddiealpha or Nadsbox) The Sardine spell checker can also be loaded in the same way.

[M100] REX + Ultrascreen100
I was excited when I came across Ultrascreen100, and it worked great when I loaded it, but after loading it if I try to run the Rexmanager the screen blanks out and the only resolution seems to be cold starting it. Is Ultrascreen100 incompatible with REX or am I doing something wrong? -Jason
Re: [M100] MIDI with the Model T
Yes, you could do it with a Teensy. The only issue is that the ready made MIDI shiields won't fit on a Teensy, since the Teensy is a different shape than Arduino. So you'd either need to figure out the pin assignment or roll your own I/O board.

Bryan Lunduke just put out a video covering the TRS-80 Model 100 from an OS perspective. Here's a link to it on YouTube: https://www.youtube.com/watch?v=Vs8PWhdoouU Just started watching it as I am posting this email...
Re: [M100] MIDI with the Model T
Thanks for all the info! My PMA-5 does have the serial connector, but it's a mini-din and I have no clue what its pinouts are. But even though I'd like to use the M100 with the PMA-5 portably, I'd still like to be able to talk to my MT-32 from the M100. I have a couple of Max232 TTL/9 pin adapters I got for Rasberry Pi projects, so I guess I could adapt one of those. Pardon my Arduino ignorance, but could this connection be made using an Adafruit Teensy? I've seen projects for connecting keyboards, such as the M100's which use the Teensy.

You can power an Arduino from a 9v wall wart or a USB power supply. If this needs to be portable, a USB power pack works great (although you may have to add some LEDs to keep the load high enough to keep the pack running.)

How often it works is a different question. " Devices like the Sound Canvas and Yamaha XG synths can accept data on the serial port at 38,400, but that's a special case and based on the firmware of the device setting its internal UART to that speed.

There shouldn't be any issues with flow control: MIDI is about the simplest serial interface there is: it's a 2-wire current loop. The specification calls for 1% tolerance, so the most you can vary is 312.5bps. That makes a maximum of 31,562.5 and a minimum of 30937.5. So 30720 is out of spec. Devices like the Sound Canvas and Yamaha XG synths can accept data on the serial port at 38,400, but that's a special case and based on the firmware of the device setting its internal UART to that speed. I've been thinking about this, and what I'd probably do is use an Arduino as a translator. You can connect the T-100 to an Arduino through a serial connection using a simple MAX232 level converter, or your can use the parallel port to send 8 bits at a time. From there, you can use a MIDI shield to connect to a synthesizer. You don't need a large program; it's basically just relaying data with a small amount of buffering. So even an Uno can do the job. Here's another summary I found: http://www.personal.kent.edu/~sbirch/Music_Production/MP-II/MIDI/midi_physical_layer.htm Although note that his cabling diagram is wrong. MIDI cables should only have the shield connected at one end. Never connect the grounds of two audio devices together through the MIDI cable, as this causes ground loops and hum. So properly designed MIDI cables (as opposed to generic DIN-5 patch cables or PC keyboard extensions) only connect the shield at one end. Tom Wilson wilso...@gmail.com (619)940-6311 K6ABZ

Re: [M100] MIDI with the Model T
We had a discussion about MIDI a few years ago and it was feasible; there was a fairly simple interface and some proof of concept software but I don't recall any actual serious software. Possibly some MIDI devices are more particular about baud rate than others but it worked with my keyboards at the time. I wonder if that discussion can still be found in the archive... m - Original Message - From: Alex ...
