I'm still digging. I found more 550 stuff. I think this is everything
that came with the 550. Here's a chance for you 550 owner's to get the
whole set at one shot!
Original DS-DOS box and invoice.
Original Sanyo Easywriter ver 1.3 disk
Original Sanyo disk box with 550 dos ver 2.11 and BASIC 1.25, two
original Sanyo disk for InfoStar (set B disk 2 and 3 of 4; disks 1 and 4
are below), original Sanyo disk for DOS 1.25 and BASIC ver 1.1
Original Sanyo disk box with all three original disk of set A, WordStar
and CalcStar and a backup copy of DS-DOS.
Two card board dummy disks used to protect the floppy drives duing shipment.
>A few weeks ago we were talking about the Sanyo 550 series and someone
mentioned one of the alternates operating systems that supported 80 track
drives in the 550. I said that was DS-DOS by Michtron.
> Today I found an old Sanyo disk package with four disks for the 550. One
of them is DS DOS 2.11, one is InfoStar, one is MailMerge/SpellStar and the
other is a disk of misc utilities. The first three are original disks. In
additon, the InfoStar, MailMerge/SpellStar are Sanyo labeled disks that
came with the 550. If anyone wants them, trade me something I can use and
they're all your's.
I was going through a box of "interesting" cards last night and I came
across three cards that I'm looking forward to using:
o Dialog DQ37 - an S-box-handle Qbus SCSI controller
o Emulex QT131 - a Qbus Pertec tape controller?
o Emulex UC07 - a Qbus SCSI controller
I found the UC07 manual on Bitsavers, so I'm good there for setup and
configuration, but I was curious if anyone knows about different
firmware revisions I should be aware of or seek to put on the card
(I've owned plenty of Emulex communications controllers, and done
plenty of firmware swaps on those, and since they put firmware (ROM
chip) upgrade instructions in the manual, it makes me practically
expect to have to do something to it).
I could not find more than a couple of comments about the QT131, but
I'm reasonably certain whatever jumper settings are on there are a)
the defaults, and b) just fine. If anyone here has any experience
with the QT131 or even better, a manual, that would be appreciated.
As for the Dilog DQ37, I can find nothing except 3rd-party resellers
offering to sell me one if I click the "give me a quote" button. The
ones I have (2) appear to have the single-ended SCSI portion of the
board populated and have a large bare patch that, from the component
values on the silkscreen, seems to me to be for High Voltage
Differential. No biggie. I don't have any HVD drives anyway. I
don't own any S-box hardware, so "just plug it in an see what it looks
like" is not the preferred method - I'd like to know more before I go
further. I'm especially wondering if this is a TMSCP-only controller
or if it will do MSCP and/or TMSCP, and if there are any firmware
variations I should know about.
So... anyone here know about these cards or where to find docs
(besides the UC07 docs on Bitsavers)?
I have a limited number of IBM 5151 monitors for sale. This is the
classic green screen monitor that shipped with the basic IBM PC 5150.
Condition is adequate. They are dirty but I will clean them up before
shipping out. Will test for basic functionality. No burn-in or other
problems, but no warranty either.
The price is $30 each plus shipping.
First come, first served.
Please contact me directly via e-mail.

I started that many years ago like 1995ish. I spec'd Tygon (brnad name)
as that was available to me. Most any generic Vinyl tubing works so long
as it fits tight and has enough wall thickness.
After about 10 years it tends to get hard, the fix is obvious.
I'm looking for more information on the Teleray series of terminals
>from Research, Inc. (Note: Teleray is the name of the terminal line,
not the name of the company! Although later they referred to
themselves as the "Teleray Division" of Research, Inc.)
In particular I'm looking for manuals and other documentation. If you
have a Teleray terminal and you're looking to get rid of it, I would
be interested in purchasing it from you.
I know of the following models:
1971 Teleray 3300
1975 Teleray 3900
1976 Teleray 3811
<1977? Teleray 3541

I was hoping for some definite direction in my endless quest to fix my C64. I don't have a lot of free time to work on this. So it is ongoing in many ways. Plus I am cautious about doing things that I know little about. Which can be good especially when you get people that give you conflicting advice. I do find a lot of helpful people on IRC, but you have to sort out what they are all telling you. I won't want to go and start buying all sorts of stuff and equipment without knowing why or then finding that I should have bought Y, when I bought X.
I know a little. Bits and pieces here and there, but nothing that will give me confidence to just dive in.
This is my quest to learn how to repair my C64:
I started with my original C64 which I bought in 1987. I had left it in a garage for two years and then tried to use it and it didn't work.
First I was told that I should clean my C64 with regular dish detergent and a hair dryer. I was told that this would solve many problems. Sounds unsafe, but I guess I will try it.
Then I was told that I should buy another C64 since it isn't worth repairing them, since they are so plentifully available and cheap. So now I have many non-working ones.
Then I need to replace chips that are bad, so I need to know how to solder and de-solder. Which kind of device to get ? There are different wattages and if you do it wrong then you burn up your boards (as a friend of mine did with more soldering experience did). Do I get a combination desolder sucker ? Or a little squeeze one ? Or a push and suck stick ? Do I get a soldering station ? A braider ? Too many different choices and combinations. I prefer something that will work and not damage my boards, and for desoldering, something that won't give me repetitive stress injury.
Then I'm told to get a diagnostic cartridge for C64, which works well expect when the PLA chip is bad and there you can't see video.
Then I should get a diagnostic harness, which works better, but again you need video.
Then I find a Diagnose 64 cartridge which tells you which chips are bad very simply with LED lights, but they are hard to find. I'm borrowing one right now from a friend and figuring out how to use now.
Then I'm told to get a multimeter, how do I use ? Which one to get ? I get one, then I'm told there is a better that could have been gotten for a little more money.
Then I'm told to get a logic probe. Which one ? Again, how to use ?
Then I'm told a logic probe is not as good as an oscilloscope. Which one ? How to use ? Then I'm told that I don't need an oscilloscope.
Then I'm told to go to Ray Carlsen's site and that will have everything I need. http://personalpages.tds.net/~rcarlsen/cbm.html. Which is very nice, but I'm a beginner and I don't need just a bunch of schematics and reference material. I need step by step method which explains which tools, techniques etc. that I need to do.
Then I'm told that going to the Rob Clarke and Bil Herd workshop would give me everything that I need to know. It is good information, but not hands on.
Hey guys and gals,
I have tried and failed to get a successful connection between my uvax II and a pc rs-232 serial port. The H8751-B didn't seem to work, so I pulled it off and wired my own MMJ-DB9 connector. I have tested the MMJ cable, and it works flawlessly.
For my connectors I have followed "The Cable" documentation at http://www.mcmanis.com/chuck/computers/vaxen/panels.htm (chucks house of vax), under "The MicroVAX II" section but it hasn't helped. I have tested the MMJ-DB9 connection from my uvax III consoles and from the microvax 3100 and it works fine, so I think the PC side is working correctly.
The MMJ-DB9 on the pc side is
DB-9 Pin Color Purpose
1 Pin 4 & 6
2 Yellow Transmit
3 Black Receive
4 Pin 1 & 6
5 Red Signal GND
6 Pin 1 & 4
When I toned out the H8571-B connector and this is what it toned out to (using a straight MMJ cable out of the connector:
DB-9 Pin Color Purpose
2 Black Transmit (Tx+)
3 Yellow Receive (Rx+)
4 White DSR
6 Blue DTR
7 Red Transmit Ground (Tx-)
8 Pin 8
9 Pin 9
Any idea what pinouts I should use for the H8671-B -> PC connector cable should be?
This situation is driving me nuts.

> software, schematics etc. ?
I have some additional material on the 960 that isn't up yet on
bitsavers. The 960 and 980 share some peripheral interfaces.
Did you end up with the 990 system as well?
