Description

DSC_1634S

ICD provided several quality products to the Atari community over the years.  This particular board is a version of Claus Buchholz’s 130XE compatible upgrade for the Atari 800XL.  ICD’s contribution is that it is compatible with both the Atari 800XL and 1200XL computers.  It contains circuitry to add upto 192k-bytes of additional memory to a stock Atari 800XL or 1200XL.  DOES NOT INCLUDE THE NECESSARY 8 256K RAM CHIPS.  BOARD AND CABLE ONLY

My clone of the board is as faithful as I can make it.  That means it is subject to the same limitations as the original.
