Spent a lot of time getting TRS-80 emulator working…finally did!
They make it hard because of the legality of owning the ROM.
But I legally own a Model 1 & 4P
Found and downloaded the TRS-80 emulator xtrs-4.9d.tar.gz
Decompress
Then in that directory…
Type make
Type sudo make install
Next you need the proper ROM…
Found level2.rom at https://github.com/lkesteloot/trs80/blob/master/roms/level2.rom
Create ~/xtrs/ROMS/
Place the above ROM in that directory
Finally
Run…
xtrs -keystretch 400 -autodelay -model 1 -romfile ~/xtrs/ROMS/level2.rom -diskdir .
