Hi
I'm trying to revive and old unix machine. A Concurrent Computer
Corporation series 8000. This seems to be a later version of Masscomp
MC5600/MC5700 which has a manual in bitsavers. The system runs RTU
(which I assumes means Real Time Unix).
My machine is in great condition and both SCSI disks (Seagate ST516)
seems to work fine and I've made images. But the machine panics at boot:
---
panic: Unauthorized use of RTU
For further assistance, contact Concurrent's
Customer Service Technical Support Group
---
The NVRAM battery is long dead and upon entering the console I get a
complaint regarding the TOD clock, but I see no way of setting it.
I can boot into a "stand alone mode" but not single user. In the SAM I
can poke arround the filesystem and use "date" to set a date, but the
clock appears not to be running.
Does anyone have experience with this type of machine, either CCC or
masscomp and can offer assistance?
It's a dual MIPS machine with 16MB of memory.
/P
The company I worked for in 1989 had three hand-me-down MicroVax II from
the US parent.
They were originally a PDP11/73 box, which had been converted.
They ran VMS 5.5-2, all had DEQNA, with no problems that I remember. They
were just networked, it wasn't a cluster.
The DEQNA may have been *unsupported* on 5.5, but it seeded to work OK.
I still have one system, and bits of the others. Failing ESDI drives put
them to the back of the garage.
I do have a replacement ESDI drive, and a Q-bus SCSI controller, so when i
get time (ha!), I'll resurrect it.
Regards, Graham
there is an 8i with similar crazy price but different user id....
hmmm.... beware?
also a Rare Digital DEC H-500 Computer Lab, 1960s, Same Switches as
PDP-8/I, Vintage for 700+
( we have an extra one of these Computer Lab, if anyone here is
interested)

thought i remember one selling for something pretty high (8000/12000?) X years

sale they saw. Although apple 1s seem to accomplish whatever that law is
called :-)
I think Straight 8's are nearly to the point that other systems which
have published tracking inventories. There are very few, this one looks
complete, or near complete.
That said I'd figure though some of the higher prices such as the
current PDP8/I and GT40 are setting for want of bids, they aren't that
far from what you have to pay to get said systems on demand. This one
may go for around the opportunistic price, and be lower, but $10 to $12k
isn't going to be surprising.
I'm here in Austin picking up that Multiflow and they have a bunch of other computers. The most intact looking is an AT&T 3b2-1000-70. There are also two rude looking IBM RTs plus an Evans and Sutherland Freedom 1000 with Sun Graphics tower, a Sparc Printer, lots of old Apple printers, and other stuff. I'm trying to put it all on Imgur but having problems since I never used it before so if you want pics email me your iMessage account and I can share it somehow that way.
Cheers,
Doug

Actually found a pretty nice hp machine with a bunch of peripherals.
Thankfully it came with the keyboard. Also a external hard drive and
floppy, as well as a tiny printer.
HP 362 "controller"
Hp thinkjet 2225A printer
Hp 9153B - HD and floppy
Also a IBM wheelwriter 3 with the parallel interface, as well as what im
assuming is a s100 backplane.
Pretty interesting. I have a couple of other Hp devices, a logic analizer,
pattern generator, and volt meter, it will be interesting to see if i can
get them talking with the computer. Computer works. boots into basic.
Pretty complete setup for something at the scrapyard.

Since I acquired a Coco Orchestra 90 unit awhile back, and I am trying
to find the source of some humming in my system when the Orch 90 unit is
operational, I looked at the schematic:
http://www.colorcomputerarchive.com/coco/Documents/Manuals/Hardware/Orchest…
(page 109 of the PDF)
I understand the ROM, the resistor ladders, and the latches, but analog
is not my strong suit. I made my way through the op-amp design, but I
am stumped on one component (actually three)?
C7,C9, and C10
They look like electrolytic polarized caps, but are NP (non polarized),
with no '+' on the schematic.
Can someone shed light on what these are and where you would find them
(or if they can safely be replaced with another kind of capacitor)? I
will admit I've never seen mention of these before now.
Are they "bipolar"?

Or, are they called something else now?

I just dug out what might be my last extra DECmate II CPU for a list
member, and now have access to several Pro and Rainbow CPUs and other parts.
If you have any interest, please contact me off list. Shipping from
Illinois.
Thanks, Paul
I have a couple of VT-52 keyboards that need repair and I'm looking for a _broken_ VT-100 keyboard to serve as a donor for switch bodies. Anybody have a junk keyboard with a few working keys lying around? Please contact me off list.
Thanks, Jack

PS I'll be at VCF next week if that makes delivery any easier.
Hello Paul,
I have a Pro380, including box, PSU, motherboard, RX50 interface and RX50.
Unfortunately no other interface, so any missing part could be
interesting, specially HD / graphics / network.
Please let me know if you find something.
I tried to forward the sent emails from two different email accounts, I
hope at least one of the two will come at destination.
I double checked for answers in the last month, including in spam, but
unfortunately no luck.
It seems there's something wrong with email somewhere...
Thanks
Andrea
