Hey everyone, I just wanted to announce thta I will be opening a new
Rainbow 100 website on Saturday, Feb 8. The site is located at:
http://www.classiccmp.org/rainbow
Right now, all that is there is an announcement. I hope everyone will
take a moment top visit once it's open.
I haven't been keeping up with everything in the Rainbow commumnity. I
noticed that all the schematics have been posted on the Update
(ftp.update.uu.se) archives. Who took the time to do this? I just wanted
to thank them. Anyway, visit the page if you get a chance! Thanks!

Those chips are:
DEC 21-17311-01 or 21-17311-02 = T-11 processor
DEC 21-17312-00 or 21-17312-01 = DC 319 DLART
DEC 57-00001-01 = KEF11 FIS
DEC 57-00000-01 = Ctrl/Data Hybride of 11/23
DEC 21-15542-01 = MMU of 11/23
I have those parts over here, and since both the original poster and myself are
located in Germany, I have already dropped them a line and helped them out.

I've hacked together a 2.11 BSD C program (nothing special, should work
on other *nixen) that takes a .tap tape file and spits it onto a real
tape. I've tested it with both a TK50 and a TS05 tape drive. It even
successfully wrote a bootable TK50 format XXDP 2.5 tape. I'm going to
be cleaning up the code and posting it on the web, but for those who
can't wait, here is the raw code. It is left as an exercise to the
reader to figure out where my MUA breaks the source code lines.

Hi Jules,
To my knowledge the largest hard drive platter was 24". IBM the inventor may have produced
an experimental platter of ~1 m as a demonstration project to management and maybe these platters
were 'sold' or distributed to IBM employees?

It's highly possible that the NVRAM's lithium battery will have
died ("gone flat") by now. This is the case with both the AV410
and AV4300 I have. My AV530s/5500 seem to be okay, but it's just
a matter of time before they face the same problem.
The machines with dead NVRAM will give some cryptic indication
of the problem like printing "IDPROM" and nothing else, and
refuse to initialize/boot on power-up.
'r. bear stricklin' was collecting NVRAM dumps for analysis, so
we can try to load usable data into replacement parts, but I've
no idea where that stands. I haven't bothered getting a part to
see if, like Suns, the machine will function at all with an
uninitialized NVRAM. Anyway if you search the archive for his
name or Aviion I'm sure you'll find the relevant post. Or head
to this URL: http://www.bears.org/~red/museum/aviion-nvram.html
The 88k Aviions were frequently SMP capable, though unless you've
got rackmount or square/big deskside units they're probably just
2-way. If you think the daughter card on yours is a second CPU
complex, look for a chip marked 88100 or 88110; those are the
CPUs. The 88200's or 88410 are cache/MMU chips.
DG/UX will support SMP out of the box. It's a decent enough SVR4
implementation, with X11 (R?) and some sort of logical volume
system. If you're looking for media I may be able to help out,
contact me directly/off-list (smj0302 _ crash _ com).

If you dig around under there, there's a wealth of PDF files
about various models. Operations guides, some about installing
options and upgrading, low-level programming for a few models.
There's been sporadic interest in getting *BSD running on the
Aviions, but little activity. OpenBSD runs on several Motorola
88k boards, and I've recently managed to assemble the parts for
a complete system, but that's as far as it's gone. I have no
history porting OSes, and I'm much more focused on trying to
find a job now, so you don't want to hold your breath waiting
for me...

Having fond memories of using VAXen (specifically, an 8800) back in my
'stoodent' days, and in more recent times too (unknown type @ JP Morgan),
and further having seen numerous references to OpenVMS & VAXen on this
list, I got to thinking...
I'd actually quite like a VAX.
Unfortunately, this is probably impossible in the short term - unless I
want to buy the MicroVAX 3100 currently on eBay @ a fiver. But that's not a
*real* VAX, it's just not big enough... And besides, it hasn't got a
CD-ROM, which I will need to load OpenVMS.
Anyway, following yet another link posted on this list revealed the PDP-11
(and, coincidentally, VAX) simulator. Nice. So I downloads it, along with
MinGW (anyone else think of "minging[1] Windows" immediately, or is it just
me?), compile it, and eventually figure out roughly how to get to the basic
VAX ">>>" prompt. And here, I'm rather stuck.
So, does anyone have any nice'n'easy instructions on how to get the SIMH
VAX simulator ready for OpenVMS? I've read both the simulator document &
the VAX document, and I'm still well in the dark WRT how to get it up &
running... Basically, I've no idea what devices to ATTACH, what or how to
configure it, and so forth.
Obviously, I'll have to sort out an OpenVMS kit before I can do anything
remotely useful, and I'll probably need an extra HDD in the PC (<1gig free
now), blah blah. (oh yes, and Hans has found several faults in my websites
which I /really/ ought to fix first... - but, well, you know how it goes :)
So, can anyone help?
TIA!

rotten (that bin's minging). UK expression (poss. Northern UK only).

I have a MicroVAX 3800 in really good shape that I would like to be able to
use, but I have a problem. The power connector looks like a standard
grounded power cable connector, but has been made in such a way that the
power cable must have a notch on the top in order to plug in. Is there any
reason for this? Does that mean that I need a special cable or can I just
take a hacksaw to a regular power cable?

I know exactly what to do under UNIX, but I'm attempting to help out
someone else - I have the Montagar Hobbyist CD-ROM and I'm trying to
create an ISO file to feed to SIMH. We have tried three different
CD-ROM slurping programs from shareware.com and download.com, but
no success. They seem to have heartburn because the disc is not
mounted under Windows.
Has anyone gone from CD-ROM to running VAX under Windows? How did
you get files off the distro?
Thanks,
