CUSTOM ENHANCED IIC ROM CHIP: $8 plus shipping

[Stephen E Buggie <buggie@unm.edu>]

I can burn the IIC enhanced ROM chip! It gives the older IIC the 
following: (A) checkerboard self-test,  (B) capability to operate the 
white-case  3.5" external disk drive, and  (C) the word "BUGGIE" greets to 
at the top of the opening screen at power-up!

Price, $8.00 plus $2.00 shipping within USA. (3.00 shipping to Canada).
(Shipping amount charged on only the first ROM chip; others shipped at 
same time no extra cost for shipping.). Installation instructions sheet 
included.)  GUARANTEED TO WORK IN IIC: each one will be pre-tested prior 
to shipping.   Long live the IIC!
