Nascom Rules !
Congratulations on the latest issues of the Club Newsletter. They were as
usual very interesting. I was particularly interested in the ‘System Software’ items
such as ‘Load and Tab’, ‘VARPRO’, ‘CC.COM’ and ‘GLOBAL.CRT’, as it is from this type
of item that one can get a much better understanding of the insides of NAS-SYS, BASIC,
I am very glad, having recently had short encounters with a PET, a TANDY, and
also with an Apple, to say nothing of a 6800 and an 8085 development system, that TI
chose (quite by chance at the time), Nascom and the Z80.
Since the Nascom 1, in early 1979, was just about the only available choice
for a cheap single board system, the choice was largely decided for me.
I have now graduated to a Nascom 2 with full DOS/CP/M available and it only
remains for me to add a colour board and an 80x25 screen format to make the system
I do have one ‘moan’. It relates to publicity for NASCOM and INMC80.
Many of the short ‘What’s Available’ and ‘Buyers Guide” items in the Computing
Magazines are hopelessly inaccurate when it comes to Nascom products and compatible
accessories from other sources. It almost seems to me as if P.C. have a bias against
NASCOM, and PCW are little better.
Similarly, the listings of Local and National Clubs have often omitted INMC80,
although I see that the club is listed in this months’ P.C.
Please keep up the good work. I only wish I lived nearer so that I could give
more than verbal assistance.
Best wishes for continued success.

Just a few points.
Many thanks for the effort put into INMC80 which continues to be a mine of
useful hints and tips and also provides a ‘clearing house” for the discussion of
certain well-known (to some) bugs in NASCOM hardware.
For the amusement of all readers of INMC80 please mention the following
misprint on P.123 of William Barden’s “Z80 Microcomputer Handbook”. Line 5 refers to
“... the eternal interrupt...”!! (Is this what sends the CPU to that great mainframe
in the sky!).
Regarding David Parkinson’s request for comments on documentation, may I
suggest a compromise in the amount of detail provided with a program? As was stated a
complete source code listing is liable to be expensive but how about:–
(a) Indicating major sections and/or subroutines by memory address;
(b) indicating also by memory address the positions of Code, Tables, Workspace
and Message Text so that disassembly may be carried out without too much Sherlock
(c) noting if any Monitor pointers or reflections have been modified.

I think the INMC80 News is an extraordinary effort reflecting much enthusiasm
and one hell of a lot of very hard work and I appreciate it enough to join the chorus
for more issues, more often. No, I’m sorry, I’ve nothing to contibute (yet) but I
would ask if you could put in a few lines stating that being a Radio Amateur (GM3TYS)
and have an ICOM IC245E VHF Transceiver, I would like to contact any enthusiast who
may have succeeded in interfacing an IC 245E/IC211 with his Nascom 2. My intention is
to do this and eventually write a program allowing frequency control, scan, search,
logging and RTTY/C.W. communication.
