Hi All,
I got a friend who is contemplating thinning out his "herd" of Nova 4's. He is
amenable to sell or trade. But want's to make sure they will have a good home.
They are all working and have aos plus a lot of documentation. The 16 bit
machines are 5100, 5230, 5280, and I believe there is a 32 bit one also, but I
cannot recall the model number (MV4000 maybe??). He also has a few 9 track
tape drives, but I got first dibs on those :-)
I'll be taking some digital photos of them sometime this week and I'll post
them as soon as I can.
Does anyone out there know what CSR Address and vector I should
set this to to make RSTS/E happy? When RSTS INIT's, it bitches
that the board doesn't interrupt, and happily disables it.
I'm using it in an 11/73, with RQDX3, 1MB ram, TQK70, the
aforementioned DZQ11, and a DEQNA.
If I do a SHOW DEV, KB1-4 is listed, but no CSR. . . .
Jeff

Over on the pd8-lovers list, someone has been discussing adding an RX8E to
his -8/i (http://www.ig-uem.ch/Docs/RX8_8I_1.pdf). I wanted to cross check
some info with the RX8E prints, but can't find them at the usual places.
Can someone e-mail me a URL of where I can pick up a pdf of the RX8E
schematics? My goal is to examine how this guy wired up his RX8E
interface to a posi-bus machine, then look at *building* an RX8L
>from M-series modules (since I have no spare RX8Es lying around).
Obviously, all I can do from here is plan, but I have all winter to do
it in. It's been a dream of mine for a long time to get OS/8 on a pre-

Yep, that?s the way the Access Zip launches SIMH to run Access or ?F?. The two
occurrences of SIMH are connected with a pair of sockets.
Sure, we know it?s inefficient. But just now, it?s the only way to run ?F? or Access,
without real hardware, and, they both do run under simulation, IOP and all!
I had a guest come over this past weekend with a set of tapes and we were able
to read and reload his tapes into a running simulation. All in all, we spent 9 hours
at it, and 2 of those were spent breaking into his system.
What we ended up doing was to ?RESTORE? a $HELLO from some other HIBE
tape in order to get past his ridiculously tight security. We had a blast banging
our heads together on it, but I want to let him tell that story.
The bottom line is that Access IS ALIVE under simulation!!!!
It only gets better from here? Take the ZIP for a spin!
Mike.
Sure,

800 MHz Pentium 3 with both occurrences of SIMH resting minimized

This actually suppressed me, some aspects of the simulation seem sluggish.
Logging in for example seems slower than I remember on real hardware.
Perhaps we should try some other benchmarks that would test the speed of
chaining with the targets csaved or saved.
Hope this helps,
Mike.
And, you checked the polarity?

Jochen,
a RLV12 Card had been sold on Ebay.de 2 months ago for 20 EUR, if I remember well.
Sometimes, qbus cards are being sold for 10 to 20 EUR, these prices seem affordable to me.

I was digging through a bunch of cables today and found a DataPoint 2400
MODEM with the cables still attached. The cables look like they're for an
HP 1000. The hoods on the far end said HP (something)(something)618. I've
looked and tried to figure out what card that might be but didn't find
anything. Asnybody know what card that is? Anybody know anything about the
DataPoint 2400 MODEM? I didn't see a manufacturer's name but it has the

Once, I got some self-adhesive labels wrapped around the drum on a
Canon, and with nothing to lose, used cotton pads and iso-propyl
alcohol to remove them. After a few sheets, it was as good as new.

All the IIIs I've seen had JetDirect cards (they all came from
netwroked environments). They only work as single-protocol in a III,
but just about any JetDirect MIO card should work, as far as I
remember. Look for J2250A, J2550B, J2552A or J2552B (that's what are
in my 4s, 5s, and 1600).

I have written a VAX test program that probes various intricate aspects of the
VAX that is running on in the areas that are defined as implementation-dependent
or UNPREDICTABLE by VARM. It runs in user mode under Berkeley UNIX. Any flavor
of Berkeley VAX UNIX should do, including Ultrix, although I can't make any
guarantees about NetBSD as it has strayed so far from Berkeley UNIX that it has
no business running on a VAX really. So if you have always wondered how exactly
does your VAX handle something that VARM lists as UNPREDICTABLE, and you have
Berkeley UNIX running, this program will tell you.
The source is available on my FTP site at:
ifctfvax.Harhan.ORG:/pub/VAX/vaxtest/vaxtest-1.0.tar.Z
I have run it on my CVAXen and the output is in the same directory on the FTP
site in file results.cvax. I will run it on a MicroVAX II in a couple of weeks
(when I put one together for testing) and on Rigel in a few months (when I port
4.3BSD-Quasijarus to it).
I have no other VAX implementations to test on, and I solicit input from the
community. If you have a VAX on which you can run this program (i.e., one that
runs any version of Berkeley UNIX or Ultrix), please run it and post or send me
the output. I need to determine the characteristics and quirks of as many VAX
implementations as possible. (If you are wondering why, this has to do with my
project of designing and building a new VAX. Yes, I know that I simply need to
follow the VAX spec and strictly speaking I don't need to look at any other
implementations, but there is also the real world.)

Care to share? :-)
I could use an 11/23 with an RL02...
-brad
I want one. I can use a PCI, ISA, EISA, MCA (PS/2 or RS/6k), NuBus
or QBus adapter. The main requirement is that hardware + software be
able to low-level format disks to RX02.
I have a YE Data YD-180 drive from an AS/400 that looks brand new.
According to a couple of comp.os.cpm posts, it's a standard interface
DSDD 1.2MB drive with DC24V/DC5V input. So far so good, and I have a
couple of older ISA floppy controllers that should talk to it (right?),
but I need a controller cable and power pinout for it. For that
matter, between the DE9 power connector on the IBM sled and the power
input on the drive itself, there's a small PDB that looks like it might
be a transformer or step-down. Anybody know what voltage the AS/400
feeds it? Anybody happen to have an 8" enclosure and PSU they don't
want?
And, most importantly, that drive *will* format a disk as IBM 3740
format, right?
I have 3 computers with RX02 drives, about 300 bulk-erased floppies,
and no way to make the floppies useful in those drives*, and that's
starting to p_ss me off.
* a couple of places I can trade degaussed disks for formatted at
varying ratios, and that's probably the cheapest way to go, but that's
hardly the point, right?

I've never found anything that confirms the actual existance of said OS
version. Although personally I don't doubt for a moment that it did
(does) exist (I've just yet to see the smoking gun). I came back to the
Apple Developer world in 95 (left the Apple Developer world in the late
80's), so I wasn't in a position to know anything that the developers
might have known at that time. Although I suspect that none did know
anything or there would be more "real" info out there.
However, I do know that the later Rhapsody project did in fact take a
turn to the Intel world. They got far enough on the first version of OS X
for Intel that it was released to developers in beta (alpha?) form. I
have a copy of it, at one point I had it installed on a P-166. It ran,
but that was about all it did. I'd have to pull out my CDs of it to be
sure, but I think the date for it was around 1997 or 1998. There should
be info on this project available out there as it was no secret, it was
originally a fully planned version of OS X, although it doesn't look
anything like what OS X is now (from what I understand, its really an
Apple-ized version of NeXTStep, but haven't never personally used/seen
NeXTStep, I can't verify that).

As some of you know, it's been quite awhile since I have posted much here.
I was off list from early 2002 until June 2003 because of the large amount
of traffic -some decidedly off-topic and a horribly stressful job. Had no
time to keep up with this and several other old radio-related lists. Now
that I'm out of work since June and presently working on a management
degree, I've got some time to at least "lurk". I like the cctech/cctalk
separation and subscribe only to the tech list.
Anyway, I have added items to the Mound of Stuff around this house during
the past August. There are several threads of discussion herein on at least
three of those items . . .
The significant goodies are a Panasonic CF-150B Business Partner and a Grid
Systems GRiDLite Plus model 1040, both monochrome LCD laptops.
The CF-150B has an 8 MHz V20 CPU, internal 720K 3.5" FDD, 640K RAM, AC wall
wart, backlit LCD display (blue characters on green background), ROMed
MS-DOS 3.30 (boots up as C:), optional 2400 bps modem (woohoo!) and
optional EMS RAM Card expansion memory (1 meg). There is a separate power
supply and a couple of spare NiCd battery packs (probably useless now), a
couple of software disks (GWBASIC and MS-DOS 3.30 Utilities) and manuals
for the modem, EMS RAM and system unit itself. The floppy does not read
disks so there's troubleshooting which needs to be done sometime.
Otherwise, it powers up and the built-in DOS & utilities work okay.
The GRiDLite Plus, on the other hand, is not so well understood. There is
no manual. A Google search found limited info here:
http://www.computer-archiv.de/comp0139.htm , scroll down the page to
"Gridlite Plus". Otherwise, just a bunch of battery suppliers.
It has an 80C86 CPU, socket for an 8087 math coprocessor (empty), backlit
LCD display (blue characters on green background much like the CF-150B,
above), unknown amount of RAM, no modem in its compartment, and an internal
20 meg HDD. Cool. Upon powering up the screen shows "Phoenix ROM BIOS Ver.
2.03, 1/18/88" and a blinking cursor appears underneath while the HDD spins
up. But the HDD shuts down shortly after it seems to do its initialization.
Then after a minute or so passes a message "Hard Disk Diagnostic Failure"
and "Disk Boot Failure" comes up. It keeps trying as another "Disk Boot
Failure" message appears every minute or so. That's it. Dang. Anybody know
anything about this particular machine? The HDD is JVC model JD3824G00-2
and is not quite the typical 3.5", 1" high IDE drive. Betcha they can't be
found too often :(
Thankfully, the external AC power supply and external 3.5" floppy drive
came with the unit. However, the floppy doesn't show signs of life during
the bootup process. Additionally, no keyboard input hits the screen
although the default 15 character buffer fills and begins beeping at the
16th keystroke. Therefore, I cannot run SpinRite to checkout the HDD system
or do much else.
The OS's that are said in that website to be used in the GRiDLite are
PenPoint, Penwindows, PenRight. What are all these??
Underneath a removable part of the case at the top rear of the machine
there is a connector for the modem and there are eight ROM sockets, all
empty. What are those for? A ROM-based OS or applications?
The internal NiCd battery had wires soldered between its flat terminals and
the respective spring leaf contacts in the system unit. Also, some clown
broke the battery compartment latch during the sale before I had bought it
thus causing the battery to not set tightly in its compartment. However the
PSU is marked as used for Gridcase 1200, 1307, 1500 and the 3403 Drive.
Maybe the 60 watt power output is too low to handle the HDD in the
GRiDLite?? The PSU model number I have is 34170 if that helps.
More troubleshooting to do. That is all I know about this machine except
for the German site shown above.
Anybody have more info on these laptops? I'm especially curious about the
GRiDLite Plus.
Another neat item I got is a really pristine HP LaserJet III for $15. Had
only 600 sheets reported on the page counter shown on its test page.
Absolutely perfectly clean everywhere inside. No stray toner powder nor
paper dust. Has a 3rd party 4 meg memory card (total RAM: 5120K). In fact
it was in its original box with manuals, all loosely covered with its
packing plastic bag. Built February '92. It didn't work, just threw Error
52's which were not described in the manual. But online searching found a
really good website, IMO, on printer repair and parts. FYI it is:
http://fixyourownprinter.com/ A few of you may already know of this place.
I followed the instructions to "tweak" a couple of connectors
at: http://fixyourownprinter.com/tweaking.html -which nailed the problem
exactly. Those connectors Canon had used (the laser engine maker for this
machine) were very poorly engineered, IMHO.
I got the LJ III from a household sale of stuff from a bankrupt small
computer service shop along with the two laptops mentioned above plus three
*carloads* of NOS mid-90's PeeCee motherboards, I/O boards, s/w, etc.
mentioned below. I figure the guy simply could not figure out the Error 52
problem. He evidently did not contact HP about warranty repair for some
reason and just chucked the boxed unit into storage for the past ten years.
Worth noting, he decidedly proved to his family and the banks that he had
NO comprehension of how to spend/save money. Hence, his bankruptcy in 1999.
Thus my ability to vacuum up some neat almost retro stuff for cheap. You
wouldn't believe the amount of NOS Tandy stuff for which I wasn't able to
find funds: three brand new Tandy 100's plus carrying cases, two of the
little PC2's with printers and a PC1 with printer, all with bunches of s/w
& accessories went for only $200 for the lot. I scrounged up about $150 for
all the rest of the stuff described here.
Just need a toner cartridge for the LJ III as the photodrum has a seemingly
permanent toner stain on its surface and horizontal groove along its length
>from where the toner scraper had set stationary for 10+ years. Leaves a
horiz. line and faint blotches on printed sheets. Will not cleanup by
itself. Okay for draft printing but not for stuff one would want to archive
such as DEC manual reprints, etc. (or my college homework :-). Anybody know
if touching the photodrum with cleaner of some sort and soft cloth will
destroy it?? The built-in scrapper will not clear the stuck-on toner. Still
that darned groove though . . .
Also, anybody have a JetDirect Ethernet card for the LaserJet III they
could part with? Cannot yet determine the exact part # at this time via
online searches. No mention in manual as this option may not have been
developed at time of publication (1990). They became available later.
Nevertheless, best deal I've made in quite awhile because when I resolve
the toner cart problem, I'll have a kind of printer I've always wanted.
Price was just fine for this unemployed fella :-)
Some of that heap of On topic and Off topic NOS PeeCee boards and misc
stuff include a Copy II PC board including manual and disk, a dozen or so
Pentium I and several P-II (slot 1) mainboards, about 15 or so 486
mainboards, several PCI video and network cards, 10BaseT hubs and NICs,
bunches of software manuals and disks (some just plain obsolete and almost
useless, others good for retrocomputing :-), a complete P-II 233 MHz
machine full of application software (working perfectly after clock battery
replaced!), a complete working Pentium I 233 MHz machine with licensed W95
and 64 Mb RAM, complete working 486 66MHz machine w/64 Mb Ram and hot
switchable, removable HDD module (only 80 Mb :-( capacity), bunches of
common ISA boards, a LOT of MFM drive cables, a LOT of floppy drive cables,
empty cases, etc. Did I mention a LOT of several types of cables?
Someday I will cull out most of the boards and stuff out of that heap (both
on topic and off topic) and make them available to new homes, but it will
be awhile. Schoolwork calls. Note: "Copy II PC" stuff is off limits! :-) :-)
OT DEPARTMENT (Close your eyes if you don't want to see it :-)
1.) Anybody have a Pentium III (three), 550 MHz, Slot 1 processor for
sale? Cooling fan too? I've got a Linux system I've hammered together from
that heap of parts I mention above for which I need this CPU. Only thing
lacking for now. Used a nice Soyo SY-6BB mainboard (early version) found in
that heap o' stuff (ca. 1998).
2.) Who is a reliable supplier of an AMD Athlon XP 2000+ CPU with mounted
fan and warranty for a fair price? Tons of 'em available online, but who
seems to be best as far as price/reputation/support, in that order? I do
not frequently purchase the latest stuff and have no good feel for who's
who. I prefer to live on the "Trailing Edge" of contemporary computing, so
this Athlon stuff is still a little out of my scope (until one or two
generations have passed ;). (Didn't Tim Shoppa name his company along those
lines- Trailing Edge?)
The Athlon CPU is for our son's new machine which Beverly and I have been
quietly gathering parts over the past several months. He'll be 11 in a few
weeks and due for a new machine to replace the Pentium 100 I whipped up for
him five years ago. At least he should have something fairly contemporary
other than just that infernal Sony PS-2. The machine I'm writing this upon
is also sorta new from about 10 months ago - Athlon XP 1500+, 512 Mb RAM,
GeForce 4 video, Jetway mainboard, windoze 98SE. Hope it lasts
(technologically) until 2005 or 6, but that of course depends upon what M$
determines we "need". On the other hand, I plan to be M$ free before that
provided office and productivity applications become pretty much seamless
between M$ and Linux.
But I still like using the older stuff . . .
/OT DEPARTMENT
Speaking of Tim Shoppa, where is he nowadays anyway? He was a major asset
to DEC enthusiasts everywhere and to the old ClassicCmp list in general.

This brings up something I'd been thinking upon once in a while. I propose
the following:
1.) For some of the more frequently discussed machines (not just DEC) there
ought to be a FAQ generated by those who're expert in a particular machine
or machines. In this case, expected MV I boot routine would be one of the
things listed plus expected failure modes based upon configuration or
hardware failures (or complete lack of an expected hardware item). Like
Adrian/Witchy, most of us forget stuff after a long time away and this
would help us with much of the troubleshooting (I forget stuff after
*short* times myself, darn it).
Actually, any machine, not just the frequently discussed machines should be
included in the FAQ archive. There are folks who know lots about obscure
machines and for the interest of preservation of our beloved machines, we
need to have access to anything that could possibly come along.
2.) Perhaps Jay could host FAQs in some sort of indexed file system, in
ASCII which is normally viewable by nearly anyone on most any platform.
Text-based files shouldn't take up much room.
3.) Also, I propose that Jay script the cc servers to automatically
broadcast a message reminding folks of the location of the FAQs, how to use
them and perhaps some basic rules for posting stuff to the cc lists (aimed
toward newbies for instance). The interval could be once a week, every 15
days, 30 days or whatever between.

You could try a BIOS update to see if this works. Also you could try deactivating the onboard IDE controller since this one usually uses interrupts 14 and 15.

I haven't played with MFM hard drives and controllers in a LONG time
(about 10 years now) so I have some questions.
I'll start off easy. Should there be any reason an old 16-bit ISA MFM
controller won't work properly in a Pentium-class PC with ISA and PCI
slots? I imagine I would just have to configure the BIOS to reserve the
proper interrupt (I believe it's 14, correct?) for the MFM controller.
I did all this but the MFM controller wreaked havoc on the system. It
killed the on-board floppy disk and IDE controllers (not physically killed
but basically disabled them and the system couldn't boot).
I'm trying to determine if there is a natural conflict before I venture
forth with this configuration. This may be a problem related to the PC
I'm trying to plug the card into because there are other oddities with the
IDE controller that is preventing the system from booting with 4 hard
drives installed (2 per IDE interface). It halts after it auto-recognizes
the drives on the primary controller. Weird.
Anyway, any insight would be appreciated.
I'm going to do more experimentation in the meantime. I'll get another PC
with ISA and PCI slots to work with, and will also find an old 386 to test
the MFM controller on to make sure it is working fine.

I remember attending a mac developer's conference when that happened.
Kin Seto (an evangelist) told me about it. They waffled back and forth
about whether to show it to anyone. At one point we were told they
would. Then later, not.
Does anyone know who the "head of technology" on that project was? Or anyone
who worked on it? (this may be the wrong list :-)

After a long hiatus from ClassicCmp (back before the split to
two lists), I'm back for awhile.
And I think I'm ready to part with a system I've had since
the mid-80s, assuming there is someone interested.
I have a complete, original-owner Zenith Z150 (PC compatible)
system. Alas, the system is not running (the last time I tried,
it was stopping on the CPU POST test). I bought this when I
was in graduate school and used it to both write the initial
FORTRAN code for my computer model, and to write my doctoral
dissertation.
This system includes the original keyboard and the single-color
(green) CGA monitor. Purchased with two 5-1/4-inch floppy
drives and a single 320 Kbyte memory card. After-market mods
included adding a 20-Mbyte MFM-RLL hard drive (below the diskette
drives, so both are still there), the NEC V20 (or was that V30)
CPU replacement, and the MR-150 (?) memory mod that let you
replace the five banks of 64K chips with 256K chips and get
full memory (640Kbyte, plus a bank below the video memory) and
a 512Kbyte ram disk (bank-switched into place).
Software (with diskettes and docs), much of it rebadged for
Zenith, but also some MS-direct upgrades, includes DOS
(various versions), diagnostics, MS FORTRAN (couple of versions),
MS Word (DOS versions 1.x up to 5.x), etc.
I've hung onto this for both sentimental reasons and because
I didn't what a scrapper (here or in China) get it. I probably
even have all the original paperwork if I look in the right box.
At this point I'd rather not part-out the system, and would
rather find an interested collector (preferably in the Midwest
or local as I'd rather not ship, unless the price is right -
I'm in Dubuque, Iowa). I recall a member of this list several
years ago saying he had a bunch of replacement boards for the
Z150, and so it could be made to be working again.
I'm not crazy...I just would rather not see the waste (and my
wife is tired of me storing and moving this system for all the
years that I have). And I'd rather focus my attention on
other types/flavors of computers right now.
Write me if you are interested (with offers and trades).
Now back to your regular programming on DEC PDP-8's, 11's, etc.,
which I need to get caught up on.
Cheers/73,
Kevin Anderson

My hunch is that MV I has a microcode console like 11/750 and 8200, so it's
going to be VERY terse and bare-bones. MV II (KA630) has a 64 KB ROM with the
console coded in VAX instructions, but you still have single-character commands
and fairly minimal subset functionality. T 50 (T, not TEST) is on the VS2000.
I know your feeling, I've also been too used to my KA655s for too long.
My current day job is implementing a ROM monitor for custom PowerPC products.
Being the VAX lover that I am, I designed it to look like a VAX console. I
implemented the >>> prompt and the usual commands, though changed a bit since
the PowerPC CPU is most definitely not a VAX (unfortunately). It's open source
in my CVS, I will post a pointer when the code is a bit cleaner so I'm not
embarrassed to show it to the world.
MS (you've guessed it right... the example I modeled it after is KA655)

I'm seeking out for a friend the game Gods for the Amiga. I'd like to get
the full original package with all the trimmings preferably.
Has anyone got a copy of this that they'd like to sell?

Actually, to nitpick, dry cells at least are properly measured under a
light load, because as they age, they develop higher internal
resistance. Measuring them with a high impedance voltmeter will
suggest they're good when they're not.

Greetings:
In attempting to salvage some files from an HPIB
drive which is ailing, I installed RMB Kermit to
do serial xfers (long files > LIF floppy capacity)
however it needs Basic 6.x and we've got 4.0.
Would a kind soul please send us the 6.0 system file
(it can be converted to an MSDOS file using the
'lifutil' utility (use Binary/DFS mode) so we
can fire up kermit and rescue the data before
the drive dies?
('lifutil.exe' is available at ftp://ftp.cybertheque.org/pub/lifutils)
All help much appreciated.

What's a good online resource to figure out what type of memory chips you have?
I have an old matrox Ultima + VLB card that has 2mb vram (consisting of 8 x KM428C25J-6 chips) and has 8 more sockets for 2mb more memory (the type where the chip pins are curled around and point to the bottom of the chip)
Are these common chips? Most video cards I have seen either use dram or edo ram.
Anyone know whatever happened to Chris Johnson? I sent off for an HP-85
>from him (back in late September last year), & still haven't recieved it!

We have some here, 2 * BY1144 triode, class B, 250KW carrier,
and TH538 tetrode, single ended, 300KW carrier. The filaments
alone on the BY1144s take 5KW.

Hi folks,
Well, I've just board swapped the entire VAX into my MicroPDP cab and it
still gets the same error and stops at 3 with an error on the console of
'00000000 03'
Can anyone remember the uVAX I's boot sequence or remember what it's
supposed to do at that point? I've just had a nasty thought in that it might
be looking for the RQDX1 and/or RD52 and it's those that are dead. Can I use
the RQDX3 in there instead?
All *looks* fine with the CPU since it appears to pass its tests.
cheers!

Jim,
Just to clarify, we are NOT trying to regulate the voltage. Just moniotor if the House AC is stable and within "tolerance". If brown outs are common it needs to be logged (even though it does NOT effect the performance of the device).
Also a low A/C voltage may not be providing enough to charge the backup battery.
Therefore none of this is part of the control circuitry, but rather more of a crude A/C voltmeter.
In terms of "how cheap", the company eliminated even low cost items such items as "berg header" type jumpers (less than 1 penny apiece!).
Also by the time it was realized (I am a software consultant to the client on this project and was NOT responsible for the hardware design) that this was an issue, the boards had already been layed-out (and about 150 of them assembled EVEN before a single line of software was written) for the 1000 piece pre-production run.
