There were variants of the 6502 with mask-programmed ROM on board (I 
have a Micropolis floppy drive with one) and 3M Iomat quarter-inch 
tape drives had a controller that's not much bigger than a file card 
that holds a 6502, EPROM, a little SRAM and a VIA.  So the thing 
*was*  suited to what we'd call microcontroller use. 

The $25 price tag may be a red herring.  ISTR that MOS started a 
price war at Wescon, and the other exhibitors soon followed with 
severly reduced pricing.  Within one or two years, a Wescon attendee 
could go home with not only a sample CPU, but databooks as well, for 
free.  I used to have a National PACE that I received in that way.  I 
think my GI CP1600 was a Wescon freebie.  The microprocessor war was 
heating up fast...
