DOCTOR DARK’S DIARY –3
EPISODE THE THIRD
This episode has been re-written about five times, due to rapid
advances in the development of Marvin, and the influence of Doctor
Dark’s elderberry wine, (more powerful than a Z8000!) Doctor Dark
strongly recommends the manufacture of wines in the computer room,
as the carbon dioxide produced in the fermentation process is very
good for putting out electrical fires.....
Marvin now has a new monitor, Nasbug T4, and as a result, I have
decided that Marvin doesn’t really need Nas-Sys after all. I have
now almost forgotten how boring it was waiting for the tape recorder
all the time, and of course am much less likely to suffer
Electricity Board repression now, thank goodness.
Richard Beal said in INMC News No 3, that programs written for T2
would run under T4, This is almost entirely true, but not if you
try to run a program where the @ key has to be used during the
program. No problem, use another key to solve that one. When all
else had failed, I had a look at the instructions, where I found a
diagram of the keyboard, with the @ key marked as the control key.
What does it control, Richard? (Try it, or read the manual! – Ed).
Another addition to Marvin made recently is a 16K RAM board,
naturally this means a buffer board and mother board too – then I
fastened it all in a Vero-frame to stop it flapping in the breeze.
The telly couldn’t be put on the top, which is wide open, so I
made a chipboard box and cured Marvin’s agorophobia once and for
all. Has anyone else noticed how difficult it is to solder chipboard?
Those of you who remember me mentioning Darkbug will be thinking
T4 has put paid to that idea, perhaps. The answer is no, because
the 16K RAM board just happens to have four sockets for 2708 EPROMs.
Darkbug is going to be bigger and better than I had first intended,
and will now be known as Darkbug 4K, Here is an extract, re-written
for the RAM on the main board, so you can all use it!
