[Coco] CoCo Model 1 Cartridge Port

[Charles Hudson]

I recently upgraded the motherboard ROMs to CB 1.4 and ECB 1.1. But I 
saw on Ian Mavric's site a "universal"  ROM that includ extra commands 
(and maybe a bug fix or two) and was wondering if that could be fitted 
to my controller.  Odds are that the hardware changed from CC1 to CC2 or 
CC3.
