Ahhh ok. I know the square root of bugger all about Altairs; I'm
mostly a DEC pdp and IBM mainframe/midrange guy. I picked up the
Altair a few years ago as an 'oh by the way' thing when I saw it at a
cheap price; I'm only just getting into it now. It does basically
work; it seems to be running some kind of ROM because when I power it
up it runs and the lights chase like a register increment thing. But
can't do much else due to broken/flaky switches.

I'll pick up some Altair schematics and see what's called for in each
switch position.

That's just an estimate from memory.  I'd have to dig my 8800 out, dust
it off and make measurements.

Note that the part I linked to is center-off-momentary SPDT.  Clearly,
not all of the switches on the Altair are like that.

There are, of course, lots of other switch vendors, NKK, e-switch...
But the C selector is by far the easiest to use.

Re: WTB several IMSAI-8080 ON-OFF-ON momentary switches

[Santo Nucifora]

As far as I know, the original Altair 8800 uses the normal full bat handle
switches.  The Altair 8800a and 8800b use flat bat handled switches as
shown on mine here:
http://vintagecomputer.ca/wp-content/uploads/2015/02/MITS-Tower.jpg

I had to find some of the flat bat handled switches and the authentic ones
are almost impossible to find.  I happened to find a person who worked at
MITS that had some spares.

Oh duh for me! Confusion reigns supreme.

Yes.. the IMSAI uses those really wide plastic paddle switches.. that I had
always assumed were a +Carling+ part, as Carling has a line of switches
with similar handles.

Altair 8800A and B both use the metal mini-toggles - the former, bat-handle
the latter, the narrow metal paddle-handle.

So you reckon those 7105SY9V3BE would suit the Altair? OK I'll go shopping.

I've had a wee Google for Altair pics and mine seems to be an oddball.
Most of the pics I've seen have all the switches the small type with
rounded 'baseball bat' ends. A couple had all the switches the larger
type with rectangular 'cricket bat' ends. Mine is the only one I've
ever seen with a mixture; small switches for address and data - large
for the control switches. See:

https://pbs.twimg.com/media/Cwi1aInUsAAW5Zn.jpg

Anyone seen another like this?

Re: WTB several IMSAI-8080 ON-OFF-ON momentary switches

The "B" model used a flatted bat handle toggle switch which IIRC weren't made 
by C I think I may have the number somewhere but I think there was a thread 
with this info a few years ago. A Google search might produce it. The Altair 
group archive on Yahoo might have it too. 

 The IMSAI uses a plastic paddle switch.

Right, I thought about that once I'd posted.

My 8800A (with B supplies) still has the basic mini bat-handle style
switches. Correct me on this, but the later Altair 8800B use the
paddle-style handle, same as the IMSAI?

The site I linked to from C is a good example of how a manufacturer's
web site should be--parameterized search with vendor stock check.  So,
for example, the momentary on-off-on 20V PC mount unthreaded with 10.67
mm handle would be 7105SY9V3BE--and Arrow has about 150 in stock.

I need those too - some of my Altair switches have the handles
physically broken... in fact pretty much ALL the large switches (the

fine). If anyone tracks down the correct type of switch please post a

S/32 - 36 are fairly well documented. It's just non-trivial to do the work
and would require someone to reverse-engineer with a machine next to them.

S34 would probably be easier though since it only has one processor and
didn't have quite as much LSI in it.

If you need some place to dump the resulting scans and disk images, I can
put them on bitsavers. I still have several boxes of S/36 documentation in
the backlog.


The architecture of both the S/34 and S/36 is very similar and both of 
teem include two processors the CSP and MSP.  The CSP handled most of 
the I/O operations as well as getting the system off the ground while 
the MSP processor executed the user programs.  Even the S/32 is very 
similar.  The S/32 was a single user machine with up to 64K of memory, a 
10MB disk and either a dot matrix or belt printer built in.  The S/34 
added more memory and multi user capability. S/36 again increased the 
maximum memory, had faster processors, a much improved user interface on 
the OS (SSP) and added one more instruction.  The MSP memory in the S/34 
and S/36  was divided into 64K segments and no program object could be 
larger than 64K.  The hardware itself is pretty unspectacular, the main 
reason for the popularity of S/36 was the availability of software and  
the ease of use of the system.  They where commonly found in small 
businesses that had no DP staff, at a  lot of my S/36 customers,  the 
person looking after the S/36 was the controller.  The user interface on 
the AS/400 was largely based on the S/36 SSP.

The tape belts can be replaced. As long as the tape was not physically damaged
it is worth spending time on recovering these, especially the SysV tape and the

I just checked in the CHM catalog, and we have almost nothing for the Intel

though we have almost every model of machine.

All three look to me like QIC drives using DC600 cartridges.  For the
Convexen this also makes sense, because we had a C240 at work in the
90s, and software distribution tapes for it were on DC600 carts.  (I
have a box of them I need to image.)

I think you're looking for the following (available at Mouser)



The bare switch isn't in stock but you can get that switch and replace 
the paddle.


It's a $5.33 experiment.

That's what I've got in my 'box-o-spares', anyway.  YMMV.

BTW, the red paddle is a very good color match to the IMSAI.  The blue

S/32 - 36 are fairly well documented. It's just non-trivial to do the work
and would require someone to reverse-engineer with a machine next to them.

S34 would probably be easier though since it only has one processor and
didn't have quite as much LSI in it.

If you need some place to dump the resulting scans and disk images, I can
put them on bitsavers. I still have several boxes of S/36 documentation in

This is making me a bit sad.  Not over the fact I can't take on
another computer the size of a small car - those days are likely
behind me and for good reason - but that this is in that class of
machines that will likely never be emulated in software.  I'm guessing
it's far more due to IBM having never released anything close to
technical documentation on the architecture than pure lack of

I have just realised that this is almost certainly nothing to do with TSS/8.

I have tried to connect SIMH via reverse telnet to my Teletype via a
DECserver 90M (I do this successfully with the PDP10 emulation), but I think
SIMH has not made the connection to the DECserver, and so the message above
is most likely coming from the DECserver itself.

So I think this is a SIMH problem, I need to work out if the PDP8 TTIX
emulation can do outbound telnet like the DZ can.

Hi Al,

I think you're mixing up the SRM (one per system) with the unit
service module. According to this document
http://www.par.univie.ac.at/publications/download/ipsc860.pdf, it's an
Intel SYP301. That appears to be an Intel 386 motherboard.

Supercomputers, fishing for information

[Camiel Vanderhoeven]

I'm making arrangements to have four (mini-)supercomputers from the
1980's shipped to me. In the mean time, I'm trying to find out what I
can about these systems, so this is a fishing expedition.

The systems are:
* Convex C1-XP
* Convex C1-XL
* Intel iPSC/860
* Ardent Titan

Pictures of these can be found on my website, at
http://www.vaxbarn.com/index.php/collection/27-odd/76-four-supercomputers
(click on the thumbnails to see a larger version)

I'd like to get in touch with anyone who knows anything about these
machines, as well as anyone who may have documentation, but I also
have two specific questions:

- Can anyone identify the tape drives shown in the pictures? I believe
the one in the Intel iPSC/860 is an Exabyte 8mm one, but the ones used
on the Convex and the Ardent are a mystery to me.

- Does anyone know what the SRM (System Resource Manager) for the
iPSC/860 physically looks like? Does it look like a PC, and does it
say Intel on the front?

Reason I'm asking is that I'm getting these out of an estate, and I
need to tell them what to look for.

Thanks,

Camiel.

Yes, I realize that; the difficulty lies in directing them in what to
look for; "anything that says Intel, Ardent, or Convex on it" is a
good beginning, but the more specific I can be in what I ask for, the
higher the chance it'll turn up.

Thanks for the suggestion. I tried it but it doesn't seem to help. Every
character I type on the terminal causes the bell to ring, it does not
respond to RETURN. If I type CTRL-C then it prints:

?LOGGING IN ON LOCAL TERMINALS IS CURRENTLY DISALLOWED

Is there something else that is needed?

Not exactly--momentary, yes, but clearly not the paddle switches used on
the IMSAI.   Fortunately, PCB-mount toggle switches are quite a bit
easier to locate.

Yes, you're right. A jumper is fitted for a non-populated bank. That's quite
clever in that the sort of shunt originally fitted is the type where you break 
the shorting bar with a screwdriver. So it comes with some shorted, if you

Ah yes...  But if the location it uses to check if the bank exists at all
fails (perhaps there's one totally bad chip in the bank) then the first
test will fail and the machine will assume the bank does not exist. It
wll not give an error.

It appears that there's a DIP shunt block on the CPU board where each shunt
corespond to a row of DRAMs. You should check all 4 positions are shorted.


According to the technical manual:

www.bitsavers.org/pdf/sage/sageandstride/Technical_Manual-1983.pdf

they should all be open.


I think that the power-on test checks the first 128K RAM, then sees if the top
location (? first location) of the next 128K works if so, it tests that RAM, and
repeats 128K at a time to work out how much RAM it has. So you may have
defective RAMs in the second 128K.


Also, the manual write it would tell me, if the test fails with the 
location of the bad Address. But it say 128K, and just boots ...



I wonder if the crashing is due to RAM problems in the first 128K.


I'm not sure my floppy disks are OK.
I'm trying to get a IBM 5170 up to work at the same time, so
will try to write them again ...

Newbie Question: How to Enable Local Logins on TSS/8

[Rob Jarratt]

I have got TSS/8 running on SIMH (actually it is a ready-made image that I
got for the PiDP8). I have set up SIMH to enable TTIX for a secondary line
to connect another terminal, but when I try to login from another line (ie
not the console) I get a message along the lines of a local login not being
permitted. I have looked through the TSS/8 manuals on Manx, but I can't find
anything that tells me how to enable local logins. Can anyone tell me how
you do this?

 

Thanks

I got booted from the list when the original post came out for this.  He isn't 
willing to ship I guess?  I wouldn't mind buying the SWTPC 6800 case he has.. I 
have almost everything save a cpu card to build another 6800 unit.

That is from the first 2000 to 5000 units its a 8800 no suffix the
ribbon is either A or Bsuffix and
a different CPU board (uses 8224). 

The orange is rosin flux that was not cleaned.   Isopropanol would clean
that but it was built as a
kit (the K suffux on the serial number tag).  Its better to leave it
that way.  Authentic, never cleaned
mine either.

The PS looks to be the original version or the first update (higher
voltage transformer).

I'd expect power supply problems, suspect one-shots (front panel and CPU
clock) and
bus level noise issues.  Assuming the switches are still good.

OK, I got the IBM 5170 somehow working, got the sage II starting,
copied the system disk (SYSTEM.IMD) to the 5 1/4 disk,

Re: VAX Common Lisp

[John Blake]

I've been looking for it for a while as well, the only place I've seen 
that has it in any form is actually on the 11/780 running at the LCM 
(which you can of course access with a free account, if you just want to 
use VCL).  I assume it must still exist elsewhere but it was removed 
from the old software product libraries prior to any of the sets I've 
found archived anywhere, sometime around 90-91 I believe?


There were several other CL and LISP implementations for VAX VMS but 
they've all fallen into the great memory hole as well.  KCL in 
particular seems like it might be easier to find since it was freely 
available, but I've had no luck.

Does anyone have a scan of the MX-80 Dot Matrix Printer Technical Manual?

It's apparently intended to be available here:

http://www.computinghistory.org.uk/det/39747/Epson-MX-80-Dot-Matrix-Printer-Technical-Manual/
but I was unable to actually download it.
I tried several other schemes to find this, and struck out.  The museum 
seems to be using a rack server service http://www.havnet.net/, secure 
checkout, of course which is broken.


I tried going thru archive.org's images of this site, and did find that 
there were epson documents on the site, but this manual is an addition 
after 2013, which is as far back as I went.  And the checkout scheme was 
there already, though the manual was not, so I stopped that search.  I 
wonder if we guessed the correct url if the manual is visible, but 
didn't get anywhere with that.


Hopefully someone can fix their server.  I have a friend who is an 
instructor in Cambridge, I will send this to her next week if you don't 
get anywhere, and see if she can contact someone who can contact 
someone, if the page isn't fixed.  Also sending a donation is asked for, 
and I could get no donation or purchase to work at all, so they will be 
missing revenue for the museum (in whatever shape it is in) till they do 
fix the page.


thanks to Scott for the other info, filed it away for when I feel the 
need to open an Epson printer.


thanks

If you do get the site working, or contact the site owners, this one might also 
be worth getting (£7.5 rather than £0, but also fails to check out):
http://www.computinghistory.org.uk/det/32320/Epson-FX-RX-MX-Printers-Product-Support-Service-and-Repair/

Covers FX-85/185, FX-80/100, RX-80/100, MX-80/100.
(Principles of Operation, Wiring data, Repair Analysis Procedures, Parts Lists, 
Repairs and Adjustments, Final Actions, General)

This book on pages 11-12 has a brief overview of the differences between the 
MX-80 versions (suggesting mostly firmware differences, and with the Type III 
including the previously optional Graftrax 80 support):
http://www.atarimania.com/documents/The_Epson_Connection_Atari_Edition.pdf

This VCFED thread also discusses the ROMs (and the 5152 printer):
http://www.vcfed.org/forum/showthread.php?24184-IBM-5152-Epson-MX-80

The Graftrax 80 installation manual also has a component layout diagram on page 
4:
https://archive.org/details/Graftrax-80_1981_Epson_America

Here is the Epson MX-80 III FT - Sams ComputerFacts:

Here is the IBM 5152-002 - Sams ComputerFacts:

If you do manage to get hold of either of those Epson PDFs on 
computinghistory.org.uk, I'd be very keen as well.

Re: WTB several IMSAI-8080 ON-OFF-ON momentary switches

Am I correct that the Altair 8800(A/B) also uses those type of switch?

If so, I need one or two as well.. my own, lone 8800 isn't quite what it
could be, IIRC. Had to sub switches.
