Main repository is here: TI99/2

git clone https://gitlab.com/pnru/ti99

here are only additional files for easier compling ti99_2 on my trellis installation and some helper files for ESP32 standalone operation to load bistream and run the hexbus server

create directory /sd/hexbus and upload "hexbus.py" and bistream compressed with gzip -9 "ti99_2.bit.gz"

ftp> mkdir sd
ftp> mkdir sd/hexbus
ftp> put hexbus.py
put> put ti99_2.bit.gz

from python console this will load bistream and start hexbus server. Serial link to commandline prompt will be lost but hexbus server should keep running

>>> import ti99

Connect PS/2 keyboard to US2 port over OTG adapter and try load/save from TI99/2 with file names prefixed with "HEXBUS.1."
