At a swap meet today, I picked up 9 VIC-20 cartridges as well as one program tape. Among the VIC cartridges was a 16k RAM expansion and one called 'Programmers Aid Cartridge' (VIC-1212). I popped the cartridge into the VIC-20 and the computer still boots right into Basic 2.0. Is this some kind of debugging cartridge then that helps with errors and such? None of the cartridges I picked up came with the docs but the ones I've tried seem to work ok so far. Also, can anyone explain the reasoning behind the different color schemes for the labels? The Gorf and Radar Ratrace cartridges I already had both have cream cases with cream/brown/black labels. The new cartridges I got today have brown cases with silver/black labels, though some have off-white cases with silver/black lables, while one has and off-white case with a silver/gold label! All of these are from Commodore.
