I've been able to locate almost all of the Corvus
service manuals now to archive with the exception
of this one. The frustrating thing is that I HAD
one of these before I gave all of my Corvus stuff
to Eric Lander (who I managed to trace down again
but disappeared before I could get anything back
>from him).
If someone has a copy of this that I could borrow
to scan, please let me know.
our roommate here has an old OSI challenger II that someone was kind enough
to break into his storage unit and tear apart, we found all of it's guts
except the CPU board :(
does anyone happen to have one?
or is anyone interested in the rest of it?
Forgive me, I'm new to BBC computers and associated techology
What I would like to know is whether the cube looking monitor (microvitech
cub?) that came with BBC computers had the following:
A scart input that took a PAL RGB 1v p-p signal that sync'd on green?
If it did then can you please let me know which models. This is quite an
urgent matter.
Thanks,
Alan Geering

Hello:
I was searching Google for anyone interested in a HP 64000
that I adopted (more like left on my porch :) and came a
cross an newgroup posting you had made and was wondering
if you could help me out.
The system was given to me under the pretext that it would
come with a a 6809 pod, but alas it only has a Z80 Pod and
something like an 8047 Pod. It did come with all the
docs. plus extra components.
Do you know where I could find a 6809 Pod for this beatie.
If you do know where I can get a 6809 pod for free or very
cheap, I would appreciate knowing about it. If not, do
you know of anyone interested in taking the system for
free. I live in the Seattle area, so it's free to anyone
willing to pick it up. Thanks!

I need the rackmount rails for an RK05J. The drive still has it's "inner"
rails, the ones that bolt onto the drives. But I need the mating ones that go
in the rack.
Also, need a complete set of rails for the 11/34 cpu... or... can I use 11/44
rails for it?

Ok, I know no one has one or will let it go if they do, but I'll ask....
Looking for the HP-85 accessory 82929A Programmable ROM drawer
I'll trade unusually high for it...

A considerable amount of Googling, et al., has turned up no
readily-available info, so I apply here:
I have a Covalent Systems model 1410 terminal, which I bought at
Weirdstuff last VCF, because cosmetically it *looks* like a VT100...
anyway it was cheap and it works, but it appears not to emulate any known
DEC CRT in it's present configuration, and the two sets of dipswitches
on the back are cleverly un-marked. (Why do 'engineers' DO this shit???
Are they ashamed of their work? DO they hate techs??)
Anyway, if anyone has any Covalent terminal info, or can point me to
same, I'd be Much Obliged.
The Collateral good news is that my 11/44 system has survived the move
and garage temps over 110F and booted up this afternoon (now that it's
cooling off a bit in northwestern Nevada) with no problems at all. I've
spent the last few hours poking around on it and trying to remember how to
drive RSX11 without having to drag a bunch of manuals out.
I was using the Covalent for the system console, and a VT220 for the
user term. I have a Decwriter on the way to use for the Console - and, I
can now have my dream come true: the Machine will live in the Garage, and
the terminals will be in my office - where it's Quiet.

Hey,
Don't know if you are still interested in info about the GenRad Futuredata
2300 but I spent a long time in front of one and still have access to it for
(very) occasional support.
We bought it in 1980 and used it to develop a MagCard debit system based on
the 8085. Used it for 6 years before transitioning to a PC environment.
Observations:
Extremely slick. RDOS II was spectacular for what it was intended for.
Assembly, linking and loading always went without a hitch. Ours had a
whopping 48K, 2 x 128K 8" Shugart drives and all the emulator stuff. You
could buy memory to take it past 48K but it only gave you a few more K since
RDOS II had to live in the upper memory. We did not use the emu too much as
we had a resident monitor that was specifically tailored to debugging what
we had to do. I did incorporate a PAL into a new design and when I
discovered that all the PAL cross-compiler stuff ran on PDPs and other
expensive machines that I did not have access to, wrote a PAL cross compiler
that ran under RDOS II that drove a ProLog blaster to get us through. This
was in 1981. All in all, a fantastic system. Even with the PC onslaught,
it took a 486/33 with a HDD to finally beat the assembly/link speeds of that
sorry, floppy-based FutureData unit.
I returned to school after all this to complete the degree in computer
science and was appalled at the sorry algorithms presented in the lower
division. The FutureData used full track buffering, double hashing and more
to make the most of limited hardware resources. Different than the current
crop of VBASIC hacks. *sigh*
As an aside. Back in those days, Intel, National and others sold their chips
with the development systems (Intellec, StarLink etc.l) like a hook. Once
you had put $20K into the development system (sometimes rack mounted!) they
figured they could hose you on their single board computers etc. at whatever
cost. With the GenRad, we could listen to them say how much more expensive
it would be to move to the next board and then watch them crater when we
told them that for less than $1K we could completely re-tool our development
hardware and .. would have! Heady times, for sure.
RJO
