Tandy TRS M-100 / Kyocera KC85 etc

Post by dom »

I don't think we've got a post for this family of portables.

The base TRS M100 has been supported for a few years and we've had a big disclaimer that other members of the family aren't supported.

Following a bit of ROM digging over the past week, the same code can be used to support the following derivative machines:

- Olivetti M10
- Kyocera KC85
- NEC PC-8201

The PC-8201 firmware differs more than the others, so has different loading instructions and option ROMs aren't currently supported. The wiki page, https://github.com/z88dk/z88dk/wiki/Platform---M100 has been updated with the new info.

Much appreciated, for some reason I'm stuck in my comfort zone of the z80 world, which is totally wrong.
I hope that the rom locations map saved you some effort ?

Yes the re-assembly made it pretty easy.

Thankfully someone had mapped the 8201 ROM to the m100 so that bit was easy too.

In theory the m200 should work with the same libraries if I can find the entry points.

I remember these machines in the Tandy catalogue complete with an acoustic coupler. Sadly the ones that have been scanned are a little bit too early to test my memory.

The T200 machine is now supported as well (no option ROM).

It feels like a target in need of a bit of love, driving the LCDs directly would improve the capabilities considerably.

No promises but I will have a try on it.
Is there a usable math library already ?
