I have inherited a HP3000 918LX. Surpisingly enough it is OT being from
1999 or thereabouts; hopefully MPE/IX is venerable enough to fit in here.
I didn't like the machine much when it was in production use as a billing
system, but now that its mine I appreciate it a bit more.
However, the thing came out of the box in 1999 with MPE 5.5 with 64MB of
RAM and was intolerably slow. It was since been migrated (by HP
consulting thank goodness) to 7.00 which did not speed it up any.
Running a few simple commands and GLANCE begins to gripe about memory and
CPU usage. I once exported an ASCII file from LOGTOOL and tried to 'grep'
the resulting file in MPE POSIX mode and it took over 2 hours to complete.
FTPing to a 90mhz (!) linux box and the grepping took three minutes.
This was one of the machine were HP inserted NOP's in the firmware so you
didn't get more speed than you paid for, but I would not mind adding some
RAM.
I have some A2580-60001 60ns RAM from a HP9000 D200 which looks to be
compatible with a 918LX. I found other RAM part numbers which claimed to
work with both D200's and 918LX's had trouble finding info on this one
specifically.
Anyone know for sure? I'd rather not release magic smoke.

I ran into those items yesterday while checking out pricing for classic computer
stuff. My first comment is ... I'M RICH :). Second (and more seriously), I read
a while ago that the average selling time for older books is five years. My
guess in both cases is that they are priced for someone that *needs* them.
I found another closed auction today for a BUNCH (approx. 25) of Northstar
Advantage computers/boards/etc. with a starting bid of $500.00 with no reserve.
Good thing I didn't see that when the auction was open :)!!!
All:
I'm doing research for another potential emulation project. Does
anyone have a pointer to an electronic copy of the Tandy Model 2000
Programmer's Reference Manual (260-5403) and the Hardware Reference Manual
(260-5404)? Alternatively, if someone has hard copies that I can make a copy
of, that'd work.
Thanks a lot.

Tony and others -
The head load pad looks visually fine. The head load spring tension
appears pretty normal , and the solenoid pulls in nicely.
The drive consistently reads the first 10 or so tracks, then tosses
various number of errors as it goes further out.
I've cleaned the head, and cleaned/lubed the spindle. The track 0
sensor appears fine.
It is indeed possible that the alignment is off - that would probably
explain the poor performance as it steps out.
I guess a worn out head would have the same symptoms.
I the 70's I had a neat Dysan digital alignment disk that I used to
realign a few SA901 and SA801 drives.
Unfortunately I no longer have it. I suppose I could mark the position
of the stepper and slightly rotate it in each direction to see if it
improves things.
If someone can point me to an actual alignment procedure I'm game - I
have reasonable scopes etc here.
I'm not anxious to replace the entire drive, but I would love to get
this up and running!
Any help/suggestions greatly appreciated.
- Gary
Other faults that I've had were a mis-aligned track 0 sensor (causing it
to step out beyond the outermost formatted track on the disk), and a
low-tension head load pad spring. In the latter case, taking the thing a
aper and bending the torsion spring by hand got it going again. The only
problem was reassembling it, I found it necessary to make a dummy pin to
hold the spring inside the load arm that was then pushed out when the
real pin was inserted through the head mouting.
In any case, before replacing something as large as a drive unit, I'd
want to know which of the various parts was the problem. Do you know, for
example, that the head load solenoid works and pulls in correctly? That
you can get a signal from the track 0 sensor? That the spindle is
turning? and so on...

Hi - I have an opportunity to pick up a large collection of vintage
computers located in Oregon. I have been told that one would need a truck
to get it all in one shot. If there is anyone who lives in or near the
"541" area code and is interested in helping, contact me directly and I can
give you the details.
Thanks.

Hi,
I've decided after many years of accumulating PDP-11s that the time has
come to restore a few of them to operational condition. I've decided to
start with some QBUS machines as they give me the best chance of a warm
fuzzy feeling of success.
The first thing I've decided to do was to retrieve all of my RD series
harddisks and establish which ones are still operational. I've initially
started with 4 RD53s and 4 RD54s which I've connected upto an 11/73 and
used XXDP to format.
All RD54s have formatted perfectly, confirming their reputation for
reliability. However none of the RD53s would format, which I guess also
backs up their reputation. I had hoped at least a few of the RD53s would
have still been usable (I have about 6 more I've not tested yet).
Does anyone have a RD53 still in working condition? Is there any point in
keeping the duff drives or should I consign them to the skip?

Specifically, the 74F382 and probably 74F381. My favorite chip broker has
a $50 minimum order.

I received this request recently by email:
-------------------------------------------------------------------------------------------------
I have and I'm tired of storing an old S-100 box, probably home-made in a
formed and machined aluminum enclosure. The whole thing is a tank of
impressive proportions and weight. I saved it from the trash years ago, as
S-100 systems were common when I first started using computers (Osborne 1
era).
Originally, it had 2 8" floppy drives. One of the drives is missing,
although I have the door for it.
Inside, there's a CPU/IO card, a 64 K DRAM card, an analog data acquisition
card, and I don't remember what else. One of the cards says MicroByte. The
front panel had a key switch, which is still there, but pulled back from the
panel.
I have no idea if this works, but at least the major parts appear to be on
hand.
Are you interested in this beast? Do you want pictures? I don't want any
money other than the cost of getting it into better hands. I'm in Eugene,
Oregon, by the way.

Too far/heavy/big for me to get it shipped here, however if there is someone

I have an RD54 with a working RSTS system (V10.?) on it.
The RD54 was installed in the microPDP-11/93 that I had.
I have a microPDP-11/53 with RQDX3 and got a few days ago
an Emulex UC07 QBUS SCSI interface with a 1 Gb SCSI disk.
Before I mess up the RSTS (because I don't know anything
about RSTS yet), I would like to make a copy (dump?) of
the complete RD54 to the SCSI disk, so I can restore the
whole RD54 to an other RD54 if this one dies ... or is
messed up completely by me :-)
I think the following steps are a starter (?):
1) install the UC07 and connect the SCSI disk
2) connect the RD54 to the RQDX3
3) start the system till the RSTS "Option" prompt
Then what?
First, I need to know the device names. Is there some
command like RT-11 ".SH DEV" available in RSTS?
Then I probably need to initialise the SCSI disk?
Then I need some sort of command to get *everything*
>from the RD54 to the SCSI disk ...
Any help is appreciated!
TIA,

I'm posting this for my friend Shane who isn't subscribed to this list.
He'd like to find a good home for his Sun-3/60. The machine is available
for pick-up (unless you pay shipping) in Calgary, Alberta, Canada.
As far as I know, this 3/60 has 12MB RAM and a CG4 color framebuffer. It
includes a color monitor, keyboard, optical mouse and the metal mousepad
as well as an external 1GB SCSI disk (not the shoebox) loaded with SunOS
4.1. All cables included. In short, a very complete 3/60!
The owner can be contacted directly at <navalpiranha at yahoo.com>.

Hi - I am attempting to install a CGA card onto a AT&T 6300 Personal
Computer. It currently has only a 25-pin CRT port for a terminal dumb
terminal (w/o keyboard). I need the dip switch map so I can set for the
CGA monitor. The 6300 has a 8086 processor, and it's an OEM system from
Olivetti. I assume that the user's guide for the Olivetti 8086 PC would
due equally as well.
Thanks.

This is urban myth appearantly. No 11/74 systems were left at customers
at the end of the field tests.
The most common myth is that Ontario Hydro whould have kept one, but
sources there have denied it. Another myth about Ontario that I've read
were about when DEC tried to convince them to change their 11/70 systems
(or if it was disks) because the money they would save from lower power
consuption of another system, which were replied to with a "maybe you
didn't hear where I come from...". I think that actually may have been a
DECUS Q&A session... And that one might be true. I don't know...
Anyhow, back to the 11/74 systems... No, I remember (and probably still
have the mail somewhere) that persons within Ontario denied that they
kept any 11/74 systems. Also, people within DEC have firmly stated that
all 11/74 systems *were* returned.

Well, it is true that DEC shipped KB11-CM cards to customers to use in
11/70 systems, but that wasn't the last of it. DEC still had/have
working 11/74 systems in house, and in the early 90s they did a
corporate wide search for 11/74 components, I believe, to keep their
systems running. (Memory a bit hazy now...)
When DEC disbanded the PDP-11 OS groups, the RSX team's 11/74 (CASTOR::)
were moved to Colorado Springs. The DECnet group's 11/74 (just 2 cpus,
POLLUX::) were also there, and FS took over the system. Well, actually
Mentec took over the system, and kept it running for another number of
years. As far as I know, the system they have still exist, but last I
heard they had some hardware problem with the machine, so it wasn't
functional. This was maybe four years ago.
Also, RSX development have finally moved off the 11/74 onto something
faster. But until recent emulators on really fast hardware, the 11/74
was still the best workhorse for the development system. Which is why
RSX have a very nice and functional MP implementation. :)
However, appearantly the physical machine stayed inside DEC, then
Compaq, and I would expect currently HP. And it sounds like there is
little chance of the machine ever leaving the premises. If it is
disbanded, it's destined for the scrap heap. Or atleast that's what I've
been told. If someone ever manage to get it out of there, I would love
to help it back to running order.

I would think that most components would be the same as the 11/70.
Looking at the module list, only a few modules differ.
Analysing it, the changes would be in the memory bus interface (that
means both cache modules and memory box bus interface). Second, the MMU
and ASRB microcode is changed. But I believe that's it.

That would be interesting to learn anything more about.
Of course I assume you know that the PDP-11/70 and VAX-11/750 use the
same memory bus, and same memory cards (with a few restrictions).

> In the past, I've run my LX [...]
Speaking of LXen....
I've got two LXen. The LX has a cgsix on the motherboard, and if you
"cd" to it and do "words" you'll see - or at least I do for each of
mine - that it has resolution-changing words supporting, among others,
1280x1024.
But when I setenv output-device to /sbus/cgsix at 3,0:r1280x1024x67 (or
whatever it is), the console appears to start fine but wedges as soon
as it tries to scroll.
However, my two machines wedge in different ways. (One just hangs,
still displaying the pre-scroll display; on the other, the video
glitches as if it were changing scan frequencies and hangs displaying
either black screen or no video, I'm not sure which.) Given this, I
rather wonder if I just have two differently busted framebuffers or if
this is just how LXes work (or more accurately, fail).
So, if anyone has an LX, a monitor capable of 1280x1024, and some way
to recover (unplug the keyboard and use serial console, or an OS if you
have it set to auto-boot, to change output-device back), I wonder if
you could try it and see if yours weird out when they try to scroll at
1280x1024?

Hi,
I have a GRiD Compass 1101, but haven't been able to determine how fast the
system actually runs.
Many sites say 16MHz, but I don't think the Intel 8086 ran that fast in 1982
- overclocked?
The Motherboard only has an 8MHz crystal, so...
If anyone has a manual, it may say.
Thanks-
Steve.
Due to an urgent need for more space, I'd like to know if anyone
would be interested in taking ALL of the following off my hands.
Doesn't have to be one person - feel free to club together with
whoever you feel like if you can arrange it fairly quickly. I just
don't want to ship individual bits of this or that to the four corners
of the globe - I don't have time :(
Here goes:
HP 85 - 5 machines (one or two may be missing a few keys). I posted
about these (and the 86Bs) on this list a while ago.
HP 86B - 3 machines. All work, for varying degrees of "work". One
seems totally OK, one seems to work but various characters of the
screen are stuck as "M" right from switch on, so I'm guessing video
RAM trouble. One has an unresponsive keyboard - a couple of the keys
work but that's it. This one also has keys missing, so is probably
best used as spares for the other two.
There are RAM cartridges and ROM drawers on offer with these as well,
also 5 off 9121 dual single-sided 3.5" HPIB drive and 1 off 9122 dual
double-sided 3.5" HPIB drive, also 3 brand new rolls of paper and 6
tape cartridges
Sun Ultra 2 300(ish)MHz - 384(ish)MB RAM
Sun Ultra 1 140MHz, not sure how much memory is in it
Sun SPARCstation 4, 110MHz, 96MB RAM, 1GB (I think) disk
Sun SPARCstation 5, 90MHz, there's some memory in it but not sure how much
Sun SPARCstation 2, 2 off, there's memory and disks in both
Sun SPARCstation IPX, 2 off, both have memory and disks I think
Sun SPARCclassic, faulty
Sun SPARCstation SLC, has memory
Sun SPARCstation ELC, has memory
Sun SPARCstation ELC (faulty) - not sure if this one has memory
Box of the system board and socket board combos from
died-of-video-problems SPARCstation ELCs. There are about 8 or so of
these, all have memory IIRC.
Sun EXP-2 disk pack (the 386i style one) - 4 (one is for spares only).
All have disks and/or tape drives in
Sun type 411 disk enclosure, DAT tape drive fitted
Sun type 411 disk enclosure, 4.3GB IBM harddisk fitted
Sun type 611 UniPack disk enclosure, 7 off, all closed-face type.
Most, if not all, have various low-ish size harddisks fitted
Sun type 711 MultiPack disk enclosure, takes 12 SCA harddisks in SPUD
brackets, complete with keys
Sun "SBUS Expansion" with card and cable
Sun GDM-17E10 17" monitor. Last known working, can't guarantee it still is
Sun CPD-1790 17" monitor, works
Sun GDM-20D10 20" monitor, 2 off. Both have different faults. One
works fine once it's warmed up, but while it does the size of the
screen "bounces" alarmingly all over the place. One has (as is written
on the casing in biro) "LINE JITTER PROBLEM". These are stunning
looking monitors - one even has its IR remote control. Make one good
one out of the pair
SGI 14" monitor. Yes, I didn't realise that any 13w3 monitors were
ever made this small, but here it is. Don't know the model number
offhand, sorry
Huge box full of SBUS and UPA cards. Along with loads of CG3 and
501-2015s and stuff, there are some rarities in here (Vigra VGA cards,
4 off; others as well)
Box full of Sun accessories - audio output breakouts, serial adaptors,
drive mounting sleds, all kinds of stuff
Huge box* full of SCSI cables of all varieties, from Sun DD50 right up to VHDCI
Huge box* full of serial cables and RS232/MMJ-related adaptors
Huge box* full of IEC 320 power leads
Boxes of mice (Sun SDB, PS2 and serial)
About 10 PC keyboards
About 10 Sun Type 4 keyboards
One or two Sun Type 5 keyboards
One Sun Type 6 USB keyboard
DEC MicroVAX 3100-30 - not sure if these have memory, they don't have disks
DEC LA38 teletype
DEC VT510 dumb terminal - 2 off
DEC BA356 disk array - full of 4.3GB and 9.1GB drives. Has a
personality module fitted, but I couldn't tell you what kind it is
Other dumb terminals - there are about 20 of various kinds, including
a Lear-Siegler ADM-11 which is retro-tastic
Box of old SCSI and IDE harddisks
19" rack mount 10baseT network hub - 24 ports I think
Drawer full of motherboards, 486 to Pentium era
Various old media (including some hard-sectored 8" floppes which I
think belong to something Tektronix)
3.5" floppy disk boxes - 3 of the "square" style (2 disks wide) and
one of the "narrow" style (1 disk wide)
Mac Plus 1Mb. Also an Apple 20SC harddisk to go with this - don't have
the cable, though.
Few miscellaneous external SCSI disk enclosures of various sizes
Some x86 machines - few 486s, couple of Pentia (~120MHz) and two more
interesting machines:
- One DEC which has the CPU on a removable daughterboard (I have 3 of
said boards - two are a single 486 and one is two Socket 5 Pentia. I
can even give you the matched pair of P133 CPUs I bought to put in
this). This machine has onboard Adaptec Wide SCSI.
One Full Tower AT - will take (IIRC) 5 3.5" drives in a nifty
swing-out cage, and 5 half-height drives (CDROMs etc). Currently
fitted with a P200 with 64MB RAM and an Adaptec 2940W SCSI card.
APC UPS system (don't know the model number offhand, but a smallish
one) - batteries are duff, but I bought a slightly bigger battery
(which has to go outside the case) and all the necessary big wires and
connectors to be able to wire it in for use
Entire shelf full of CDROM drives, including 4 Nakamichi 5-disc
changers (two SCSI and two IDE)
7 off 3.5" HD floppy drives
Several large bags full of various cables and x86 accessories (floppy, IDE, ...)
Few boxes of various ISA/VLB/PCI cards - mainly graphics and network
Probably a bit more stuff that I haven't listed, as well
The catch: you must take it ALL. Currently, it's filling a room (and
overspilling a bit from that) and I want it gone. I'd say this is
going to fill at least 2 estate cars, so you'd probably want a van. I
can help you pack and carry it out.
How much? Make me an offer. The offer can be from "free but I can have
it gone REAL SOON" upwards. I really wouldn't say no to some cash ;)
This stuff is teetering ever closer to getting landfilled; I'd hate to
see it be lost to the community but I honestly can't keep it any
longer. I hope someone/some group out there can give it a good
home(s).
Ed.
* where these are concerned, you can take the *contents* of the box
