PC-186 |
The Nimbus PC was redesigned at the sametime as the 286 and 386 units were introduced.
"Packed into a neat, low profile no bigger than a video recorder."

The redesign removed the short lived ROM Cartridge slots, drive power was via mainboard connectors, not direct from the PSU. Memory IC's were changed to mb81c4256-10p with 1mb onboard as standard.
Gone was the Nimbus specific 84 key keyboard to be replaced with an industry standard 102 key PS/2 keyboard.
