When I started this list I really didn't anticipate how long it was going to get! It was just meant to be a brief list of the documents that I found in my shed... Then it grew... and grew...

I have been wondering how to catagorise it. Eventually I have decided to list it in approximate chronological order. This seems as good an idea as any!

I have listed Circuit Diagrams seperately.

Me Original photographs " various old notes on bits of paper!

Almost all the above are complete and original, but some are photocopies. This list is only a part of the collection...

Some documents are, unfortunately, not dated. Also there was a tendency for the Nascom literature to carry dates a bit earlier than the actual availability of the equipment. However, the dates given for Issue 2 documents should be about right. In some cases (i.e. the first issue of Nascom-1 kits) the documentation provided was in provisional form. I suspect that this would have been the "Issue 1" version.

Amongst the NASCOM-related magazines:
inmc news Issues 1 to 7 Complete - continued as INMC80 News
INMC80 News Issues 1 to5 Complete - continued as 80-BUS News
80-BUS news Issues V1/1 to V3/1 May be complete - V3/1 is Jan-Feb 1984
Micropower Issues V1/1 to V2/4 Complete - continued as nascom newsletter
nascom newsletter Issues V2/5 to V3/5"6 Complete
INUC NEWS May 1979 " July 1979 I think there *were* only two!
All the magazines/newsletters listed above have been an invaluable source of information, particularly when piecing together the history of the Nascom company through its various troubles. Many thanks to everyone who was ever involved, directly or indirectly, in producing these wonderful pieces of history. Special mentions are also listed on the Credits page. As the NASCOM computers never caught on with any "big" magazines (apart from PCW - see below) there is very little documentary information available.

There was also a review of the Nascom-1 (and the cover picture) in the first issue of Personal Computer World. I thought that I also had a copy of this but I can't find it now. As far as I know, the NASCOM-2 didn't even get a review! I am prepared to be proven wrong on this though...

I do NOT intend to scan this lot onto web pages! However, if you are stuck for a bit of information I may be able to help. Please don't ask for complete manuals. Some of them are quite large and I don't have free access to a photocopier!
