This project has 2 facets : Arduino to TI protocol & Serial Term ASM program for the TI92.
Note that as it is a -1st version- of the TI92, it doesn't run ASM programs directly, so I had to implement patched backup file (FARGO & .92b) sending to TI (it took me a while).
Now I use the arduino to send backups, send SerialTerm Application & use as SerialTerm "cable" to adapt TI protocol to Serial protocol (RX/TX TTL)
This is how I received my out-of-order TI, it was dusty & oxide...
I started to disassemble mother board & clean it with white vinegar...
I checked for the batteries crossing line, found the +5vcc & choosed a GND from anywhere on the motherboard, then soldered a micro-usb plug to POWER it again
TI - USB powered... It's ALIVE !!!
