Dear friends,
A friend of mine got an Hitachi MB6890 computer with a pair of drives.
Does anyone has a clue of how to copy its disks? Where to find disk images?
Thanks
Alexandre
I just got a Digiac model 5504 disk drive exerciser through eBay. It didn't include any documentation. The basic features seem pretty straightforward, but I'm hoping to find documentation to figure out the less-obvious stuff, like those "fault enable" switches under a locking cover.
It'll probably make an appearance on my web page eventually. For now, curious folks can see pictures of it on the eBay listing:
http://www.ebay.com/itm/230590661812
I plugged it into a 5.25" floppy drive and was able to start and stop the motor and move the heads around. I'll probably try to get some alignment floppies one of these days.

Does anyone have RT-11 actually running with two MSCP disk controllers?
My 11/83 has a CMD CQD220A/TM at 172150, and an RQDX3 at 160334. The rqdx3 has an rx33 floppy drive, and is set for starting LUN 4.
No matter what I do, RT-11 simply won't see the floppy. I've run sysgen, specified the addresses of both controllers, nothing works.
So, if anyone actually has a running system with dual controllers, I would love to see the SET DEVICE stuff that makes it work.
Thanks for any advice.
Guys,
Many of you know about us - www.hpmuseum.net, and that we are located in the
convenient-for-everyone city of Melbourne. We are planning another
consolidated sea shipment from the US later this year. So, if you need to do
any HP closet-clearing, or know anyone who does, please put them on to us.
Our ship-to address is in Southern California (city of Orange). We pay for
shipping.
We are not just looking for hardware, software and manuals. We are also
interested in newsletters, user magazines, promotional material and videos,
etc. Thanks for reading and keep up the great work!
Cheers,
Jon
I have a quantity of 11/44 boards and backplanes and can sell either
complete sets or individual parts. Shipping from 61853. Please contact me
off list if you are interested.
Thanks, Paul
A TECO distribution has the manual in RUNOFF format. I'd like to run
that through a decent text formatter to get a PDF.
Does anyone know of a RUNOFF manual that will tell me the meaning of
the directives so I can translate this file into troff and then
process it into PDF?

Hi folks,
Over the next few weeks, I'm going to be trying to liquidate some
"dead weight" -- meaning, things that I don't have time to poke at and
have fallen down the list of projects I want to work on. So, probably
nothing terribly exciting, but if anyone is interested in any of it,
I'd like to give them the chance to take it off my hands.
I have two items to get started with.
1. A KA660 MicroVAX 4000/200 in a BA123 pedestal chassis. It has
memory errors, so it can't boot past the system console, but it might
be a fun project for someone who's into VAXen. It comes with four 16MB
MS650 memory modules, a couple of RF35 (I think) DSSI disks, and a
TK-70 drive. That's it.
2. Compaq AlphaServer DS20e. No skins, just the bare rack-mount
chassis. I think it's got about a gig of RAM and about 18GB of disk.
It's fast, you know you want it. You can run OpenVMS on it and impress
your friends.
Location: Fremont, California, USA, conveniently located near Decoto
Road and I-880. You come pick up, sorry, I can't ship anywhere.
Price: No reasonable offer will be refused!
Drop me a line off-list if you're interested in either (or both!) of
these.

The BT-100 from the Communist-era Czech Republic. I'd not heard of
this before. Nicknamed the "runaway nail", it's a dot printer. Not a
dot-matrix: it only has one pin. :?)

Do you remember an old printer jednojehli?kovou BT-100, some know it
under the name "runaway nail". The manufacturer of this printer was
easy to Tesla. On his plastic box boasted logo Matrix Printer. The
printer can print on paper size A4, printing principle is the simplest
you can be, despite the carbon. Control and monitoring of moving
needles and paper is very slow, everything is controlled by computer.
The quality of the printing also has its problems, but prints.
We realize that nowadays the printer is BT-100 for its long time to
print virtually unusable, even though we have it decided to join the
C64 and develop programs for printing. This project is BT-100 is
opened, and this site will publish various information programs for
printing, and everything what this veteran piece of hardware is
concerned.
________________________________
Update: 13 June 2008 Hardcopy BT-100 v2.1
New, but still binary version of the BT-100 Hardcopy for printing
bitmaps to the printer jednojehli?kov? BT-100 contains two new
features. Needle printers neproklepne hard paper in order to print it
is necessary to swap the carbon paper with paper that is loaded in the
printer. It is still necessary to horizontally flip the bitmap,
otherwise the resulting print was mirrored. Function for flipping
bitmaps Y-axis is implemented in this version.
Another very practical novelty is the analysis of the bitmap. This is
performed on the principle of virtual printing. First, list
information about the structure of the bitmap. It is the number of
printed pixels, the area percentage and the number of blank lines. It
is also listed how many apartments will be sent to the printer and how
many will be synchronized truck. Finally, the analysis is the
calculation and listing the estimated time of printing. This is
dependent on the structure of the bitmap, and of course on the
selected print quality.
Complete instructions are included in the zip package or here .
Selected print quality concept
Estimated time of printing is 5 minutes 29 seconds
Actual print time is 5 minutes 35 secondsSelected print quality concept
Estimated time of printing is 11 minutes 29 seconds
Actual print time is 11 minutes 39 seconds
Between estimated and actual time to see a slight difference. Practice
has shown that, even in the repeated printing of the same bitmap is
some time difference. This implies that the estimated time to print
accurate to the second, of course, impossible. In practical tests, it
was confirmed that our estimated printing time is given with an
accuracy somewhere around 2%.

Update: April 30, 2005 Diagnosis BT-100 v1.0
The tool is designed to verify basic state function printers BT-100.
Self-diagnosis is mainly focused on the test of optical sensors and
servos. This way you can test the functionality of the basic elements
of the printer. Termination whole diagnosis consists in printing a
test page. You can then check the resulting print quality and
especially the synchronization accuracy. Instructions for use of the
program is here .

Update: 28 July 2004 Hardcopy BT-100 v2.0
The new version of BT-100 Hardcopy looks at first glance like the
previous one, but something is different. The adjustment was made in
the main core of the program, the handler routine for printing. The
front features of this new driver is speeding up printing. Speeding is
that the truck cutting head goes only to the last point, which is
printed on the current line. Taking in the old version carriage drove
up to the end of each line. For comparison, the new version over the
previous two demonstrations, we use the new driver properties in
practice.
Selected print quality normal
time of printing in v1.0 is 17 minutes 24 seconds
time press in v2.0 is 14 minutes 49 secondsSelected print quality concept
in v1.0 Print time is 13 minutes 56 seconds
time press in v2.0 is 4 minutes 4 seconds
The sample text is seeing rapid shortening of the time of printing in
the new version of the driver program Hardcopy BT-100.

Update: 23 April 2004 Hardcopy BT-100 v1.0
As the name suggests, this is a program that copies the video screen
directly to the printer. Strictly speaking, the HIRES graphic prints,
graphic screen where data is stored at $ 2000 - $ 3F3F (decimal
8192-16191). This portion of graphics memory is used as a graphic
editor Art Studio. The program is implemented and functions such as
preparation of the printer (ie, offset paper), the possibility of
inversion graphics, a choice between quality printing concept or
normal. Indeed even the BT-100 can print different quality.
Instructions for use of the program is here .
As stated before printing can be done with different quality printing,
concept or normal. The quality concept is best used for printing text
(in this choice does not affect the quality of the final print), or
simple images (printing is performed quickly at the expense of
quality). To achieve better print quality images with a high density
of points you need to select the print quality is normal. It takes a
little more than a concept, but the print result is even better. The
following example can be compared.
DraftNormal
Printing takes a very long time, and listen to the antics of one
needle is cruel repair. Resolution HIRES graphics is 320x200 pixels,
it means that one has to cope with needle to 64000 points. The maximum
printing time (if in each line of at least 1 point) is indicated in
the table.
Concept: 16 minutes 47 seconds
Normal: 20 minutes 56 seconds
Another front driver properties for printing the truck unnecessarily
nep?ej??d? blank lines automatically leads to a shift of paper
processing the next line. This implies that the printing time is
proportionally reduces the number of blank lines. For demonstration we
present two examples of printed quality concept.
Number of blank lines is 40
out time is 12 minutes 22 secondsNumber of blank lines is 186
out time is 1 minute 18 seconds
After getting familiar with the characteristics of the program get to
the download section and subsequent practical use. The D64 disk image
is stored outside the Hardcopy and diagrams and descriptions printer
connection, Noter with instructions for use, and several bitmap for
test printing.
