Nascom 1

Our Nascom 1 kit is in excellent cpondition and complete with expansion boards, manuals and circuit diagrams.

The Nascom-1 sold over 12,000 units in the first 18 months of being on sale and was the brain child of Kerr Borland and John Marshall.

The Nascom 1 was a single-board computer kits issued in 1978 and officially launched in Januaty 1978, based on the Zilog Z80 and including a keyboard and video interface, a serial port that could be used for storing data on a tape cassette using the Kansas City standard, and two 8-bit parallel ports. The inclusion of a full keyboard and video display interface was uncommon in this era, most microcomputer kits at the time only being delivered with a hexadecimal keypad and 7-seg display. In order to keep the cost down, the purchaser had to assemble their Nascom by hand-soldering approximately 3,000 joints on the single circuit board.

Why Nascom? Because the idea of a low cost computer intended for U.K. hobbysts was originated by an American company called Nasco. However, the board was designed in the U.K. by Shelton Instruments Ltd that, later, also designed and sold the Sig-Net.
