Ya, that's what I'm (trying) to do.  It's been 30 years since I've had
to deal with assembler, so I'm not willing to do that.

But, otherwise, it works.  The new project is on:
https://github.com/rlauzon/rdos

It implements a sort-of-TPDD protocol and the client programs are
written in BASIC.
But it does work and works quite well so far.

I removed the features of the TPDD protocol that I didn't need (like
format drive and drive status) and changed others ("previous file" is
"change directory" in my project).
I allow you to use all 24 characters of the file name field (for
naming the file on the disk - you still have to deal with the file
name limitation on the M100).
It will "boot" the loader program by doing a LOAD "COM:98N1D and
pressing a button.
Once the loader program is there, you can load the save, list and
utility programs.
I implemented directory handling, so you can use a nice, big SD card
and subdirectories.

I've booted up from a hard reset on my T102, loaded up all the
programs, and played for a bit.  I still need to really kick it
around, so it's in alpha test right now.

About $85 in hardware (I had the 32 GB SD card, drive activity LED,
boot button and 9-25 serial cable laying around).
I only needed to solder the headers to the SD Card shield.  Everything
else was just plug/play.
