Dan,
I know this is really old... but do you still have these?
I have the following guides available, if there is any interest:
6025000 "Guide to Operations"
6025005 "Technical Reference"
I have 2 of these and lack power supplies (large external ones)
and video/keyboard interface. These have a DB25 that says Video
but not much else. other than a few serial ports. I have no idea
if they have CTOS on them or what OS . need at least the power
supply bricks.
Any experts out there.
Thanks, Jerry
I recently saw an old academic paper out of Clemson that had this
bibliography entry:
M. H. Kelley. A look at the DG/UX file system.
Technical Report 3, Data General Corporation, 1990
Anybody have any pointers on getting a copy? I've seen no trace of it
on the web, and actually very little DG/UX info in general (even some man
pages would be interesting), but the ancient marketing stuff I have
seen makes me suspect they had one of the earliest journalling
FSs in UNIX, and I'd love to know if that was really true.

One of the few items damaged in the shipping of our PDP7 from University of Oregon was a handful of the front panel switches. The switches themselves are a standard telephone switch and are still available! But the long, tapered bat handles were unobtainium.
So, one of our folks with above-average mechanical aptitude *made* some for us:

Pretty cool, huh?
UNIX is user friendly. It's just selective about who its friends are.

Speaking of front panels, I've always wondered:
In my days with Burroughs systems, the operator consoles that had
"front panels" and many of their maintenance panels used illuminated
momentary push buttons that toggled on/off; that always struck me
as more intuitive (not to mention faster to set up) than separate lights
and switches.
Granted it would require extra logic to latch the states, but was that
kind of front panel ever used on any of the micros and minis that we
discuss here?

Might be pushing 'classic' a bit.... as the 'oldest' of these three
is only 7 years old.... so... if these aren't 'classic' enough yet...
please forgive me :-)
So.... which one is best in your opinion ?
The 2000 takes UltraSparc III, 8MB cache (at 200mhz bus), the
2500 and U45 use UltraSparc IIIi, 1MB cache on chip (but how are
the cycles to it ?)
Beyond that, memory tech differs... 2000 takes ?, the 2500 takes
ECC DDR266, and the U45 ECC DDR333. The 2000 and 2500 do
SCSI, while the U45 does SAS/SATA.
But beyond that, how is reliability, how is USIII vs USIIIi performance ?
The 2000 will do vertical UPA, right ? (I have some C3D cards from
U60) The 2500 looks like fastest slot is 64 bit 66mhz 3.3V PCI (so
what Sun GFX cards go in there?). And the U45 has PCI-X and PCIe x16.
(I assume graphics there is usually via the PCIe x16, right ?
Looking for 'best' desktop Sparc.... assume it would be one of these
three, no ?
Thanks,

Hi Neil,
I have some mmd-2 doc's do you still need them?
CDC short microprocessor course text reference and lab which uses the MMD-2.
MMD-2 Tutorial Users guide
MMD-Exec C source listing
As I just e_mailed you for MMD-1 data, IT looks like our paths need to cross...

Hi Joe,
I came across this page and this comment from 2005:
http://archive.netbsd.se/?ml=cctech&a=2005-01&t=640496
"Actually I have a pile of iSBC 215 HD controller's but they're
configured
for the 86/330 systems and I don't have the proper PALs and jumper
settings
for them for use in the MDS systems."
I found your e-mail addresses elsewhere. I sent this e-mail to both the
addresses hoping that one will still be active after four years.
I was wondering if any of the cards are serviceable and would already be
suitable as HD controllers for an INTEL 86/330 system. If so, might you
be willing to sell any? The details for the controller of interest are:
Description: Winchester Disk Controller.
Part Number: iSBC 215B
Host: Intel 86/330 with RMX86 operating system.

I picked up a Omrom programmable terminal. Picked up is the operative
word as the thing weights around 70 pounds!
It appears to work in spite of a disjointed space bar (fixed) and the
model number is 8030.
There is a rotary knob on the back that sets the baudrate (up to a
whopping 4800 baud) and what appears to be 4 rs-232 ports, one parallel
port and a coax port labeled TV ??
Anyone ever use these? is there a manual/pdf out there. A google search
does not appear to bring any good results. It does have a cool NASA/DOD
sticker on it!
Cheers

Hi,
i got a request from someone who wants to emulate a DB8490 in a FPGA ...
... this will be used for a homebrew NS3532 system, that will somehow emulate a pc532 (to get
NetBSD up and running ...).
Unfortunately, i don't have my National data book currently at hand (it's somewhere hidden under
some piles :)), on bitsavers, i didn't find it too and google wasn't me friend too ...
Does anyone have an online copy available ?
Thanks a lot
Bernd
