23	23	*  - memory modes with IOCNT0, currently ignored
24	24	*  - timer event counter mode (timer control register, bit 6)
25	25	*  - TMS70x1/2 serial port and timer 3
	26	*  - TMS70C46 is same as TMS70C40, except with support for memory mapped I/O?
26	27	*  - when they're needed, add TMS70Cx2, TMS7742, TMS77C82, SE70xxx

	49	CC-40 is powered by 4 AA batteries. These will also save internal RAM,
	50	provided that the machine is turned off properly. If a program is running,
	51	you may have to press BREAK before turning the CC-40 off.
	52
	53	To run a cartridge that doesn't automatically boot, use the command
