Comments

Because the NASCOM 3 was designed to be adapted and expanded by the owner, there was really no 'standard' specification.
The NASCOM 2 was essentially the NASCOM 3 with no case, a simpler BASIC, slower cassette interface and no graphics.
See this review for more information on the NASCOM range.
