'' described as "really a computer course on their own". ACFA, Inc. (Affordable Computers for All), was founded by Andrew M. Veronis, a doctorate of computer science more well-known for his books on computer engineering. In the United States, the computer sold for $695 as an assembled kit or $595 unassembled. Computer journalist Fred Ruckdeschel felt that it needed an additional $300 in hardware on top of the cost of the unassembled kit to bring it on par with its contemporaries. To that end the ACFA-8 came with a RS-232C serial port for peripherals including
