I think its similar to the Ti protocol, only different, IYSWIM ;-)

The .cas format is simple, similar again in design to the Ti format.. just
uses different headers and stuff :-)

Hum, anyone feel like teaching me asm then ? :-) I only need to know
about waiting on a chr from the port, and sending a chr.. oh, and
accessing Ti List memories.. oh, and asm in general ;-))

The whole idea, or just the adding extra power IREDS ?
