I have a Timex/Sinclair 1000, and happened to pick up a little book that
has more hardware information in it than any other book I've seen (by the
way, I haven't seen the Explorer's Guide to the ZX81). It's titled 'The
Ins and Outs of the Timex TS 1000 & ZX 81', by Don Thomasson and subtitled
'A Hardware Manual for TS 1000 & ZX81'. The book is published by
The text on the back cover describes the contents of the book (reprinted
without permission, of course):
"THE INS AND OUTS OF THE TS1000/ZX81 contains the complete circuit
diagram of this amazing microcomputer, as well as a full discussion
of the unorthodox methods which are used in making this microcomputer
do what it does.
"Don Thomasson discusses the structure of the TS1000/ZX81, and how
you can add additional memory and expand its capabilities.
"The book also includes a number of projects which demonstrate the
potential of this microcomputer, from using it to control a model
train set, right through to connecting it to a printer."
This is the only book I've seen in bookstores that contains the
internals of the TS 1000/ZX81. It also gives plenty of information for
adding peripherals. I still can't believe where I found it: I was
browsing through the book section of the local K-MART! Even there, I
found the price a little steep ($11.95), but it seems to be worth it.
Since I've paid for my admission to this newsgroup with the above
information, I have a question I'd like to put to the readers here: Just
what do you people *do* with this "marvel of electronics design"?
(Quoted from the aforementioned hardware book.) I've owned one for a
year, and have yet to find any real use for it. I'd appreciate hearing
from someone who has come up with a purpose for owning a TS 1000/ZX81.
I'm not terribly interested in hearing about games on it; it seems as
though most *any* other micro would handle them better than the Sinclair
in terms of graphics and memory capabilities (although arguments against
this position are welcome, of course!).
If you do have a use for it, tell us about it, including any
hardware modifications you made and why.
I'd like to see the responses posted to the net, as this has been a
pretty dead newsgroup lately, but I will summarize and post any responses
mailed to me.
