We have in the library:
"raytheon 706 computer users manual"
at SMECC.
Wanted to see if it was online somewhere.
Nice shape tight binding with an additional errata and addendum
pamphlet accompanying it.
I see bitsavers has manual but not pmphlet.Also there is no color front
and back cover, which
if you have the computer is cool artwork for a display. -
Anyone with a 706 out there?

Dumb question...did the '451 have a mechanism to work around the
instruction restart issue in the 68000? Or was there some other way
that was handled?

I?ve recently acquired a rare complete set of 10 TRS-XENIX 1.0 Development System floppy disks. I?ve done quite a bit of 8? disk imaging so I'm fairly comfortable using ImageDisk, cleaning disk heads, etc. I?ve run into a scenario with these disks that I have not had to deal with before. Since this is the only complete set of this software I?ve ever seen, I need to be really careful with how I proceed. The media itself looks pretty good. No scratches, no blotches. However, on a number of disks the sleeves have warped. I am afraid that this will damage the media when I spin them up. I?m thinking of cutting open the sleeves and placing the media in new 8? floppy sleeves. I?ve also heard about baking the media, although I?ve never tried this and not sure of its value.
What are your thoughts on how to proceed?
Hi folks,
I've got my VAX3800 resuscitated after many years in limbo and two of the
four RF71s in there have gone bad. Has anyone tried swapping the controller
boards between drives? Is it just a matter of letting the drive
auto-calibrate or do I need to SET HOST onto the controller and tell it it's
on a different HDA...
Here it is in a happier mood shortly after first powerup:

I don't see these manuals online at either bitsavers.org or hpmuseum.net.
Does anyone have copies of them available?
12044-90001 HDLC Direct Connect Interface Hardware Reference Manual

I have more than one HP-1000 CPU. Just curious what it would take to
connect some of them together running 91750A DS/1000-IV software.
So, I'm winding up to boot Unix V6 from an RX02 floppy. So I need two things:
- Details of how DEC ROM bootstraps boot from RX02's. I vaguely recall seeing
documentation of this somewhere (e.g. which sectors it loads, etc), but now I
can't find it. Don North has dumps of the RX02 ROM's, but I'm too lazy to read
through the code and figure out how they work. Is there some documentation
which covers it? I did a quick Google search, but if there is anything out
there, my Google-fu was inadequate.
- Did anyone ever do an RX02 driver for the V6 disk bootstrap? (Well, I guess
a V7 driver would work, too.) Note: what I need is _not_ either i) the Unix OS
driver for the RX02 (I found one of those already), or ii) a driver for the v7
standalone second-stage bootstrap (which would probably be in C). The thing
I'm looking for would be called rx.s, or something like that. Yes, I could
write it, but again, I'm lazy! :-)

I have uploaded a set of disk images from My Compupro system with an 8085
and 8086 card, plus regular z80. The thread starts a number of years ago,
but today I just updated, at the bottom, to include images of the disks I
have for the system.
Some interesting concurrent CPM and DOS stuff, not sure if this is really
MS DOS 1.25 or not, never got it to work on my system. I'd love to see
someone else make it work.

Just get the IMD images:

As always, thanks Dave Dunfield, please use the images with the proper
licenses, etc.

SEEKING GOOD ILLUSTRATIVE MATERIAL ON IBM ADD ON BOXES GOT A STACK..
So need hi res scans of catalogs brochures etc showing them all
stacked and what when with what.
We had an early IBM pc for a while....but never this many add on boxes!
I am lost... Remember back in the 80s I sold HP stuff... any
help and guidance appreciated to make this all come together into
something nice visually!

Well, that's over almost 30 years - and your total from that period is about
4% of the remaining stock (and in a commercial operation, to boot, not
hobbyist)...

Sure, but try looking at it from our perspective: we either use an
out-of-production part, or have to design something (almost certainly from
discretes) that meets those specs; and we actually looked at the latter (viz.
Dave B's design). However, after some pondering, and taking everything
(including all the below) into account, we decided to go with the original
chips, since they were still sorta available.
Which is why both we and Guy have stocked up on them, at the start of the
process: we don't want to crank out boards designed for a certain part, and
then not be able to get the out-of-production parts the boards were designed
to use.
If we were designing something for serious production, that wouldn't be an
option, but for limited-volume hobbyist use, it is. The choice of an
out-of-production part does have a down-side, but it's minor (and mostly
alleviated by the pre-buying), and the other options were (in overall sum)
worse.

But, but... I'm _already_ buying them from unreliable sources, then testing
them! :-)
But to be serious - if the demand for QSIC's, etc, runs the well of DS8641's
dry, yes, we'll probably have to re-design. In other words, we'd be right
where we'd be today if we decided not to use out-out-production parts.

Hi all --
Just wanted to let you guys know that a new version of the Xerox Alto emulator I've been working on at the LCM+L has been released; V1.1 of ContrAlto can be downloaded from: http://www.livingcomputers.org/Join/Online-Systems.aspx. At this point, the vast majority of software appears to be working properly, if you do run into any issues please let me know!
ContrAlto is open source, so if you want to hack on it the source is available on our GitHub site at https://github.com/livingcomputermuseum/ContrAlto.
Thanks!
