The MicroAce machine was one of the first clone computers ever made. It is a clone of the Sinclair ZX-80 (not the 81) and contained an identical ROM and 1KB of RAM. The 3.25 MHz Z80 CPU was quite powerful although the RAM really limited its potential.

The interesting thing about this machine is that its parent company (MicroAce) was sued by Sinclair over the machine, and the judge did finally find in favor of Sinclair Computer but only because the keyboard was identical. He could not see the ROM so he couldn't wrap his head around the fact that they were the same. Eventually, MicroAce licensed the technology from Sinclair prior to both companies going bankrupt.

"Comp Shop" in Barnet (North London) reimported the pre-built Microace computers and sold them as "refurbished". My Dad bought me one for my 14th birthday. With its 2K of RAM it was enough to play ZX Invaders on it.

The ROM was functionally identical to the ZX80, with some address and data lines shuffled (I should know as I shuffled the data on an Exidy Sorcerer :) ... and picture this ... The boss and I were each soldering together an early kit on the shop counter, when QUICK! Hide these under the counter! .. as Clive Sinclair enters the shop :D
