letters to the editor
Read, Try and Learn
There have been several letters from people who have built’ their
Nascoms and have yet to acquire the “knack” of programming. Perhaps my
experiences would hold out some hope.
Before last April when I bought my Nascom I knew very little about
computers, in fact I wasn’t even sure what Hexadecimal was. After
building the kit and getting “hands-on experience” through the Software
Manual things became a little clearer, but it wasn’t until I bought the
“Z80 Instruction Handbook” published by Scelbi that I really began to
understand what it was all about. The Scelbi book is pocket sized and
explains all the Z80 instructions in simple language, assuming that the
reader knows very little, which was certainly true in my case.
It was about this time that my children were doing tables at school and
so I thought of the “Table Tester” which times their answering the
table of their choice, in random order, and if all answers are correct,
compares their time with the previous best.
I have enclosed the program for consideration for the library, if only
as an example of what can be done by a beginner. I can now see that it
is not very well compiled, having, for instance, no entry verification.
But IT DOES WORK, if only the correct keys are pressed.
Now to hardware.
No doubt there are others beside myself who have Nascom 1’s and would
like 2’s but do not have the necessary. Apart from that, part of the
reason for my buying a Nascom was that it was easily and, relatively,
cheaply expanded. Apart from Nas-Sys and the Basic ROM, what else is
required to bring the Nascom 1 to Nascom 2 standard (apart from speed)?
Is there to be a conversion kit or is it to be done piecemeal?
My thanks to yourself and the INMC committee for such an enjoyable and
Well congratulations on “getting it together”. Your program will be
considered for the software library.
We are afraid that expanding an N1 to an N2 is piecemeal as apart from
the items you mention, you will also require expansion RAM and buffer,
an Econographics kit from NM, the Cottis Blandford cassette interface
from Newbear, not to mention sundries like the “snow plough” and “Reset
