[Coco] CPU speed in MIPS

[Joel Ewy]

I'd be interested to see how the CoCo would stack up against the 6502
machines doing multiplication...  Maybe sometime I'll dig out the
Kaypro, the Osborne, and the Morrow Decision Systems (all CP/M machines)
and see if I can figure out how to get their BASICs working (some have
several different ones.)  What CPU is in the T1100?  8088?  Do you know
what clock speed?  I have some Texas Instruments PCs that use the 8086. 
It would be interesting to try those out, and also compare with an
actual IBM PC (8088 @ 4.77MHz).  I've also got a TI/99 4A, a Timex
Sinclair 1000.  And somebody should try this out in BASIC-09.
