Re: Heathkit ETA-3400 vs. ETW-3400 confusion?

[drlegendre .]

I've been reviewing the 'conversion' document, found here:

https://nerp.net/~legendre/heathkit/3400/ET-3400_ET-3400A/Heathkit%20ET%203400_modification_manual.pdf

Which describes how to modify the ET-3400/A to mate with the ETA-3400 accy
unit. For some reason, a number of details - pictorials, it seems - are
missing from the document.

All of the missing details seem to involve modification and connection of
an 'RF shield' component, which might refer to a copper tape strip which is
part of the ET-3400 package. Apparently, the they intend for a wide copper
strip to interconnect the ground planes of the two chassis..?

My sense is that the info was left out as it's unnecessary to achieve
correct operation.. more of a "the FCC made us do this" sort of thing. Can
anyone comment on the omission, and any importance it might have?

-

(My complete Heathkit 3400 series document set is here:

http://nerp.net/~legendre/heathkit/3400/

It includes all of the scanned 3400 materials I have collected, and I
believe it is complete, less the BASIC programming course materials. All
other documents, including the self-taught courses should be present.
Please advise if anything is missing, or if you can supply the BASIC course
documents.

Hey, thanks for the catalog link. It confirms that the 'W' designation
indicates factory-wired units, in the case of both the trainer and the
accessory unit. But note the difference in assembly costs between the
ETW-3400 and the EWA-3400 accessory, I'm surprised that the latter would
take any more time to build than the former, but I'm sure they had their
reasons.

And it appears that the $47.00 chip option is for the extra 3K of SRAM that
the accy. board can hold (for the max total of 4K). Both the tiny BASIC and
monitor ROMs are standard equipment, and included in the regular price - or
at least they were in 1979.

Just a suggestion.

Everyone that has mentioned the RD53 has mentioned that
eventually (unfortunately sooner rather than later) the heads
end up sticking.  There has been an extensive description
of what to do, but it does usually require a clean room to
perform - although many have managed without that by
doing it inside a plastic bag.

So do NOT depend on any files on the RD53 since they

Check out the PDP11_DiagnosticHandbook_1988.pdf   and XXDP25 on the web.  
You’’ll need to create a bootable RX50 (or emulated TU58) image.

There are several RX02 diagnostics programs and ZRXF (NRXFAO) excercises RXV21. 
 Others test the Drives.

Re: Set of mystery DEC boards: who can help me identifying these?

[Noel Chiappa]

> From: Pierre Gebhardt

> I uploaded some

Well, I don't know what they are, but a couple of things about that first
board (the one that has the 3 blue Berg headers on it):

It has jumpers for UNIBUS grants (both interrupt, and DMA). Which doesn't
necessarily mean much, the various MK11/etc memory cards (M7984, M8728,
M8750) have them too, and they _definitely_ don't plug into a UNIBUS. But
this card has nothing connected to the CDEF connector pins, but it does to
the AB, suggesting that whatever it is, it might go in a MUD slot?

Someplace I have the pinout for the M9014/etc UNIBUS extenders (cards that
plug into a UNIBUS in/out slot, and convert it to 3 40-pin flat cables), but
I can't find it at the moment (I remember discussing it here, so maybe it's
in the list archives). It would be interesting to see if this card has the
same pinout.

RXV21 and 11/94

[Rod Smallwood]

Hi

 Having decided that the best way to get the 11/94 going was to 
sort out the RX02 and make sure I could boot from


it.So back to the 11/83 make sure it boots of the RD53 - Yup RT11

Try the RX50 - Yup boots xxdp.

Now then 11/83 - QBUS  so  an RXV21 to drive the RX02.

But where to put it. Next to the RQDX3?  After it?  In front?

Better ask:

Knights of the  most  excellent order of Digital Techno Mages.

Where does put ones RXV21   Next to the RQDX3?  After it?  In front?

Yes, if you look on ebay, there is at least one person who makes cables
that snap into the IBM Model M plug with USB, I believe it has some sort
of in-line electronics near the plug.  It's worked flawlessly with the
various
Model M's I've used it with (and bought some more, all work great).
I used it on '86, '89, '91 ones.

BTW, I can confirm that Unicomp did buy the molds, etc. from IBM/Lexmark.
(spoke to the owner during a call a while ago...)
The "innerds" they make are form identical to ones that came from IBM.
I can confirm this in that here at work I bought the "guts" and some Mac
keycaps (guts with the USB cable hard-wired... that's the only difference)
And found an old Model F (which was a UK version of a model M, not
sure what else was difference) and the guts dropped in.  I did cut off the
tabs to allow for the additional keys next to the space bar.   This works
out because the mold had a cross-beam where the tabs connected to
the bottom edge, so you can get a smooth even edge without much
cutting, etc.

That's the only shortcoming I've found from Unicomp, the "enclosures"
are light weight, and definitely not the same plastic as IBM (in composition
or weight).  So a case from a donator model M fixes that problem.
(usually run the case thru the dish washer before to get it squeaky clean...
yes, my wife lets me do that, as long as I'm not running dishes too...
she's a keeper :-) )


Earl

p.s. If you do ever order the "guts" (not sure if they still do that or not,
make sure you indicate what you want on the keycaps... I didn't mention
and got completely BLANK keycaps... works for me since I'm a touch typist,
but had me laughing and I did have plenty of spare caps, so put normal
ones on and have the blanks in the parts bin)

FS: (PURGE) all sorts of classic computer parts, computers, networking, ink/toner, etc

[rescue]

Hi everyone,

I am looking to clean out some of my stuff.  I'm 'buried' in it.

This is just the begnning so if you are looking for anything in 
particular; PC, Mac, Sun, SGI, misc, feel free to inquire.


If you want to get heard above the noise when replying (spam sucks), 
add PURGE into the subject line that will help me find responses or 
inquiries fast.


So, here is the first batch of stuff, organized by drives, misc, kvm, 
wireless, PC, laptop, Sun, SGI, Apple, Digital (DEC), Cisco, and finaly 
toner and ink cartridges.


Obviously there are so many items here, it would take time to price all 
this stuff.  So I'm open to reasonable offers.  I'm not trying to make 
it rich, I'm looking for a reasonable amount so that you get a decent 
deal, and I get this stuff move on out.  Eventually if it doesn't move 
it will go into storage, recylced, or dumpstered.  I've got to get some 
space back.


There are lots of parts here, but also some completed (or mostly 
complete) Macs, PC, Sun, SGI, etc.  I have some older PC laptops to 
list, and I'll have more Mac, Sun, SGI, and more to list as time goes 
on.  But I have to start somewhere so here is the list



Drives (hard drive, optical drive, mo drive, etc)
-
SCSI hard drives (too many to list) (I have a number of Sun and 
generic, i.e. good number of ST11200N, and some ST31200N for an example)

IDE hard drives (too many to list)
SATA hard drives (qty of 250G, a few others)
ESDI hard drives (a few)
MFM hard drives (some, i.e. Maxtor XT1140, Maxtor XT2190, Micropolis 
1325, etc) (I'm not dumping these, just listing them for those who know 
what they are and want to inquire with real offers, so this is listing 
for completeness, not to make space like most things here)



Misc

15" XVGA LCD monitor, no stand, but includes a wall mount bracket.  
Power supply included.

RJ45F to DB25M kits.  Still sealed, make your own pinout

Hi,

I have really fond memories of this operating system (from before the
SVR4 Solaris days).  It was the first UNIX I used (and I'm still a big
BSD fan).

(Not sure what the protocol is here for asking something like this so
if I run afoul of a copyright policy or something, just tell me to
stop asking and I will.)

Is there any way someone can get their hands on an install disc for
this?  I have some old SPARC hardware that it would be fun to run on
if I could find the installer.

Thanks,
Bryan

CORRECTION

I am wrong.  The W means assembled in the factory apparently.

For another $47 you could by the chipset for either the W or T versions.

Yes when one retires senior takes on a whole new meaning!!

Yes that's the one! The HXIDL  must be their bus interface.
What a challenge !

>From the Modification Kit page 1

"This Modification Kit will let you interface the ET3400
and the ET-3400A Microprocessor Trainers with
the ETA-3400A or EWA-3400A Microprocessor I/O
Memory Accessory"

".The following steps will modify your Heath ET-3400
Microprocessor Trainer so it will operate with the
ETA/EWA-3400 Memory I/O Accessory."

There is a manual for the ETA that includes both Tiny Basic and Wintek
monitor.

It just makes sense to me that T = Tiny Basic (and Wintek monitor), EWA
means Wintek monitor (only).

To prove this, find the manual entitled: "SOFTWARE REFERENCE MANUAL for the
MEMORY AND INPUT/OUTPUT ACCESSORY for the ET-3400 Trainer Model EWA-3400

The ETA version part number is 595-2271-01, the EWA must be close to that.

Back then, getting an extra BASIC ROM would have been a measurable expense,
especially for a school that had no use for BASIC to be included in their
trainers.

Osborne 1 in San Antonio

All,
this advertisement appeared yesterday in my company newsletter 
classifieds:

Working Osborne 1982 Computer, model OCC-1, S/N 119840, with Users Reference 
Guide, software programs: Word Star, Lotus 1-2-3, Pearl, Chef, Paschal,

It is not likely to be a scam as only SwRI employees are allowed to 
place ads, but I have not contacted the seller directly. Other than being 
employed at the same place, no connection to the seller. She does not mention 
whether she’s willing to ship; I would expect not but might be convinced for a 
high enough offer.

Finally found a moment to take a gander at that:

The KDJ11-E memory seems to be parity only, not ECC.

There's a Parity CSR at 17772100, which will tell us if a parity error was
detected in the main (on-board) memory. There's also a Memory System Error
Register at 1744, but that's only there for backward compatability, and
I'm not sure it will tell us much.

It might also be good to look at the system CSR at 1526, which will tell
us if the firmware has set the memory size to how much memory is actually on
the machine.

There does not appear, alas, to be a register that indicates _where_ the
parity error happened. However, if it's happening regularly (and still, as
in 'problem disappeared in the process of diagnosis') we should be able
to work out where it is.

Although I'm still somewhat astonished that a persistent parity error wasn't
picked up by the self-test on power-on.

In theory, you should be able to plug most QBUS boards into those slots
(although if there are QBUS cards that barf in a Q/CD slot, one couldn't use
them - I can't recall if any such exist, though), but... no device board is
going to work properly since the two QBUS bus grant lines (BDMG and BIAK) will
be wired past those slots, directly from the CPU to the KTJ11.

On the 11/84 backplane, there are a couple of jumpers that _can_ send the bus
grants through the 'QBUS' slots on the 11/84 backplane (so _in theory_ one
should be able to plus QBUS devices into those slots, and have them function
correctly, when those jumpers are set appropriately, but we have yet to
confirm that), but I don't know if the /94 backplane has anything
similar. Alas, there are no 11/94 prints online (that I know of) to confirm
that.

Excellent! The more known good, working components we have to play with, the

16,600 blocks on an RL02 disk pack of which over 9,000 blocks are

V05.07 RT-11 distribution.

Using RX01 floppies will take many more since there are only half 
the blocks

or 494 blocks on a SSSD (RX01) floppy.

Do you have any other questions?  I don't know of any RT-11

on RX02 image files for either V05.06 or V05.07 of RT-11. There may
be some for earlier versions.

Internally, each SAV file has a version and each MAC file also

I do have a pair of RX01's but I am less sure about the controller.

Also available is a TK50 UNIBUS CONTROLLER not a TUK50 CONTROLLER as

The only two relevant dates that I am confident of are for the RT-11

RT-11   V04.00   February 28th, 1980   152 files 3213 blocks
RT-11   V05.00   March 12th, 1983   182 files 4026 blocks

I assume that you may have distributions for V04.05B of RT-11 and
V04.05C of RT-11.  I seem to remember that between 1980 and 1982,
DEC provided update files to users who were paying for the update

Well I have moved on a bit more.
My 11/83 is back together and booting RT on the RD53 via the RQDX3
as normal.

I found not one but two RXV21 RX02 controllers.  So I'll  give them a 
try in the 11/83 and see what happens.

I'll soon know if the RX02 is good or not. If not I'll fix it (my era - TTL)

Re: Heathkit ETA-3400 vs. ETW-3400 confusion?

[drlegendre .]

@Tom & All,

"In following this thread, and taking in my "vast" Heathkit knowledge, I
can only assume that the addition of a 'W' in the model number is to
indicate a WIRED (at the factory) Heathkit."

Fair enough, and it's as good a suggestion as anything heard so far. But
again, you're confusing the (very easily confused) model names..

The ET-3400 and ET-3400A are the original "trainer" kits. These are the
main computer module, with a calculator-style keyboard, 7-segment LED
display, and either 512 bytes or 1KB RAM memory. I believe that the later
'A' version also includes the 4MHz crystal-controlled system clock upgrade,
in addition to the larger RAM size.

The expansion modules are confusingly called out as ETA-3400 (note, not
ET-3400A) and ETW-3400. It's these latter two distinctions that are the
cause of my (and apparently, much) confusion. But your suggestion that the
'W' substitution refers to a factory-wired unit makes good sense, at least
in this case - because my ETW-3400 seems to have been factory built.

It doesn't have any of the tell-tale signs of kit assembly. For instance,
it appears that the board has been wave soldered and washed of flux. The
rest of the workmanship gives the same impression of factory-quality
assembly.

So maybe that's all there is to it? The ETA-3400 is kit form, and the
ETW-3400 is factory built?

CAPLIN CYBERNETICS HXIQ and HXIDL

[Rod Smallwood]

Hi

 Whilst sorting through my board collection I found a pair of dual 
height DEC style modules.


CAPLIN CYBERNETICS HXIQ

It looks like a ST interface  (data  and  control connectors). But 
here's the kicker. Its got a transputer chip on it.


The two connectors are wired to the second board (CAPLIN CYBERNETICS  
HXIDL) that has what looks like a flat cable SCSI connector as output.


It looks like it was made in the UK (some RS Components parts) about 
1992 by  the date codes.


Any ideas on this one guys.

Rod
