Paul,
Many thanks.... heres hoping I can get the info I need from them to get this
machine back up and running.
Regards
Simon

I've scanned the schematics from the 480Z Information File and put them
online. However, they are hand-drawn, so I've had to scan them in
grayscale at 300dpi in order to be readable.

Well, the idea is this; Simple three line basic prog running on the calc, doing
'input#' for data from a sound card. The encoding format is kind of documented
as is the text->bin conversion. There are already a pair of programs that will
handle conversion from wav->bin->text or bin->wav, just not text->bin->wav.
They're also DOS utils with no source availibility, and their support for the
PC-1
(Sharp PC-1211) isn't 100%..

I wasn't that lucky... when I did it, I shorted a cap thru my finger
(fortuantly, just thru ONE finger, tip to knuckle). I was working blind
in a terminal, and I thought some animal was in there that just ripped my
finger off... I was really expecting to pull out my hand and see a stump
where my finger had been. Instead I had a really cool exit wound on the
tip of my pointer (but not as cool as the one on my elbow when I shorted
theater lighting thru my forearm)

Since I'll be running another headless computer (HP 9000/380), I brought home
my VT420. Nice terminal, but unfortunately this specimen will only talk, not
listen.
At first, I suspected my HP had lost its settings (the stupid boot PROM must
be set via the keyboard to use a serial console). I proceeded to bring my HIL
keyboard home and set it (without any screen) to use a "remote" console again,
and the machine seemed to acknowledge that, beeping happily. But no response
>from the terminal. So I tested it with my DECstation. No response there
either. So I hooked it up to my Amiga. Typing at the keyboard, there was
output in NComm, but doing the opposite didn't work at all.
So we have only one-way communication. What could be the problem?
The cable works fine, I'm getting

ATM would be good, and although there's a lot of it around, you should be
able to pick up a couple of routers fairly cheaply.
Acorn Econet? There's Linux support for that too.
How about the original DIX Ethernet? Try a web search for Aloha.
Sinclair (Timex) machines like the Spectrum and QL used a proprietary
network, but I think the only other company to ever use it was ICL.
Do you count ADSL, ISDN, X.21, or just LAN stuff?
10base2, 10base5, 10baseF (and FOIRL), 10baseT, 100baseTX, 100baseT4,
100baseFX, 1000baseTX, 1000baseSX, 100baseLX and 1000baseCX are all closely
related and you will find some excellent references at
http://www.techfest.com/networking/lan.htm
10base2 and 10base5 are bus topologies using 50-ohm coax; 10baseF (and its
predecessor FOIRL), 100baseFX, and 1000baseSX/LX are fibre technologies
often used as point-to-point but can be used in star networks too; 10baseT,
100baseTX, and 100baseT4 use UTP and are normally used in star topologies.
Before you get too carried away, you might want to think about the
permutations of protocols, technologies, and topologies or you'll need a
much larger house :-) The same fibre that carries FOIRL can (if it's the
right size, 50/125) carry 10baseF, 100baseFX, 1000baseSX, ATM, FDDI, ...
I have a thin Ethernet (10base2) segment, a thick Ethernet (10base5)
segment, a lot of Cat5e carrying 10baseT and some 100baseTX, a chunk of
FDDI, some FOIRL, 10baseF, and potentially 100baseFX, at home; and there's
lots of redundant ATM kit at work but (a) I have no room, and (b) I'd have
to buy it (which is against my religion). I also have some Econet, ISDN,
UUCP serial links, etc.

Haven't carrier pigeons been extinct long before IP and UUCP were
developed?

I have a 5110 tucked away in a corner (I was actually just thinking about
it yesterday). I don't know if I have the tape you are looking for, but
if you tell me what I should look for, I can check.
Are the 5110's of any collector value (not that I would ever part with
mine, but I am curious if it is just me that wants to keep it, or if it
is actually a valued machine). Mine has this big dual 8" floppy drive
box. I *THINK* it might also have a 5mb hard drive built into the floppy
box, but I don't remember (the thing has been shut down and in storage
for about 12 or 13 years... so it may not work anymore)

Sounds like this device uses the same "stringy floppy" tape as the A&J
Microdrive and the Wafadrive.

Try comp.sys.sinclair. Be advised that Entrepo made two types -- A and B.
Same tape, different housing. I have A&J drives (one each A and B type)
hung off my TS2068.
The drives are slow, and the tapes are extremely fragile, to the point that
I rarely use the drives any more, in order not to destroy my few remaining
tapes.
