TI-99/4A UCSD pCode on UberGROM Cartridge

This video does a quick demonstration in Classic99 running pCode from cartridge. It shows that the cartridge includes an 80 column mode (hopefully compatible with 9938 as well as F18A), as well as ROMdisk with the basic system utilities and a flash drive for user use (about 40k). I demonstrate building and running two test programs entirely on the cartridge with no floppies mounted. Note this is running in Classic99 with Overdrive enabled -- the real pCode, even on cart, is a lot slower. https://harmlesslion.com/software/pco...
