I have a project I'm in the middle of, hopefully I'll successfully complete it on Wednesday.
Next step: Trying to remember how to program the 1284P with the GROM routine!
If this project works, I'll never have to deal with the color bar screen or selection screen again when this cartridge is installed, as it will always go straight into 4A/DOS, even from a power up!
After that, I'll make an BATCH file that does all my TIPI stuff upon boot-up, THAT will be a HUGE time saver!
For step one, I turned 4A/DOS into a 512K image for the UberGROM cart. Once the GROM routine is programmed into the 1284P, it should immediately take over the TI and load 4A/DOS from the 49F040.
I'll be giving my public thanks for the help once it works!
