There is another clue in this. I thought it booted DRDOS from the first
message.
I am not really familiar with DRDOS but I suspect a disk formatted under that
would be different from formatting under MS or PCDOS.
Do check your BIOS settings and battery.

Take a look at the PrinterWorks web site (http://www.printerworks.com/).
They have exploded diagrams of the printer (you have an 'SX engine')
with all the parts identified. You should be able to get a part number
for each roller.

Not necessarily. If these have been passivated, your

Hi
Just joined the list and came across this in the October archives from Rich Beaudry. Sorry but I don't know if I can contact you off list.
I know the posting is a bit old but I thought it would not hurt to ask.
I am looking for one or more IBM 3270 Microchannel cards for a pet project of mine. If you (or anyone else) still have this one card available I would be happy to pay the shipping costs and even offer a couple of dollars for your trouble if you like.
I could use more than one if anyone else has any that they are willing to part with.
Thanks for your time,
Michael

>May I ask a very simple question. What machine are you using this with
(from the description below, I assume a PDP8). If it _is_ a PDP8, do you
have the reader control relay mod fitted correctly? If not, then you
_will_ drop characters I think.
My computer is an 8/L. I do not have the relay fitted at all. After a
careful examination of the schematic and manuals, this relay only forces TTY
power on, in LINE mode (this is redundant if the TTY is already on and
prepared to read a tape), and also forces 115V to the distributor trip coil
so that a tape will immediately start reading if present. Without the relay
a manual start is required by simply flipping the reader lever to "Start".
Everything gets up to speed after one or two characters of leader no matter
how the reader is initiated. No characters will be dropped since the program
will loop indefinitely at the usual KSF, JMP.-1 until a character is
assembled and sent to the TTY receiver card.
>That's very odd. The most obvious mechanical problem would be wear on the
ratchet wheel teeth in the reader. But that would cause problems once (or
n times) for every revolution of that wheel (and the drive sproket) --
Quite. That's why I'm scratching my head!
>So what you're saying is that it sends the correct number of chracters,
but some of them are corrupted to 0's?
Yes, when an error occurs while printing the test tape I can "hear" the
nonprinting character being sent to the typing unit (it "jumps" but nothing
appears on the paper) and the next consecutive char is then printed
correctly.
>Either your read pins are misaligned (they should come through the middle
of the tape holes --
check this), or the contacts are sometimes not making properly.
Agreed. They look centered to me (but what IS the definition of "centered"
i.e. at what point in the read cycle? The tape and pins do not seem
perfectly stationary with respect to one another during the read cycle.)
The manual shows that the sprocket wheel should be rotated forward to take
up the slack against the detent at which point the pins are centered in the
holes. IF I'm reading this right. Actually they show a "Gate Flash" that
looks like a hole on the side of the sprocket, which does not exist in my
reader.
>Try running the reader without tape, with the EOT sensor held down. It
should then send all 1's. Check that it does (use the PDP8 for this with
a similar program to yhe one you've written already, just get it to halt
if the character is not all 1's). Let it run for many minutes.
Excellent suggestion, thank you. I will try this right away.
>A really Heath Robbinson (Rube Goldberg?) trick
Who's Heath Robbinson? I always liked Rube Goldberg's inventions...
>3) focus a camera on the reader mechanism. Set the aperture appropriately
for the flashgun. Make the room dark, hold the shutter open on B, let it run
4) When the flash fires, close the shutter, turn everything off
5) Develop the film and hope that it shows you what the problem is.

Sounds awfully complicated. Perhaps I can do this with my Sony digital
camera if it has a sync input!
thanks for the tips

They sell a rebuild kit for the LJ2 that addresses the jamming on pickup.
They also have a number of other kits available, for assorted common
jamming problems with that printer series.

Dear Sir, I have a hp7974A magnetic tape reader and now I can
read/write data on a magnetic tape via gpib+code (by C++) with 1600 PE
density. However, the written data cannot be read our another hp7970B
tape reader due to the fact that It can read the data with 800 NRZI
tape density. As far as I know, hp7970E series can read both. Is it
possible to buy one of it? and did You know where can i buy one?
Thank you.

Hoping someone has some spare rackmount parts.
For my 8/E, it was pulled out of a rack, so it just needs the
parts that are inside the rack -- approximately 1+3/4" high
sliders; my /E has the part that goes *into* the sliders.
For my 8/M, it needs the complete rack kit, as does my 11/20.
Anyone able to help out?
Thanks in advance,

Hello:
Let me chime in on the number of Mark-8 computers, etc. Several years ago I
went through some old records that showed the royalties paid to me by both
Radio-Electronics magazine and Techniques. R-E paid a small royalty for
each of the instruction booklets they sold. You may recall the original
magazine article could not hold all the information and construction
details. Techniques paid a royalty on the sets of printed-circuit boards
(PCBs) they sold. Based on the information I still have, I figure R-E sold
about 7500 copies of the booklet, and Techniques sold about 400 sets of
PCBs.
Unfortunately, the original R-E article and the booklet failed to publish a
key piece of information: the wiring diagram for the board-to-board
connections. So, I heard from many people who needed this information, but
these communications took place before email and low-cost fax, so I have no
record nor recollection of how many people I spoke with.
As you can probably guess, I also have no idea how many people actually
built a Mark-8, nor do I know how many of those built systems still exist.
My original Mark-8 is in the Smithsonian, and it was in working condition
when it left here, so that counts as one system. The prototype memory board
for the original point-to-point wired Mark-8 prototype went to the American
Computer Museum in Bozeman, MT in October. The ACM also got mimeographed
copies of the original "Mark-8 Newsletter" and its successor, the "Micro-8
Newsletter."
If anyone has questions about the Mark-8, refer to the Web site:
http://www.his.com/~jlewczyk/adavie/mark8b.html
which contains information I wrote back in 1999. (I need to go back and
clean it up a bit.)
Please note, the email addresses in that posting are incorrect. People can
reach me at the permanent email addresses:

or
jontitus(a)hendrielane.com
For a while longer, the jontitus(a)attbi.com email still works. We expect a
shift to comcast.net sometime soon, though.

Hi
I guess the next question is, does anyone have the
dumps of these chips or what the new mapping is??
I suspect that there is some remapping of the memory
and some for the I/O. I don't know why it would take
3 chips though. I'll have to dig through my stuff to
find a schematic. I may be able to figure it out from there.

Mike Davis,
You probably already have an answer on your question about a ribbon for the
Juki, but on the rare chance you haven't:
Ribbons for the IBM Selectric II work on the Juki. Some of the newer ribbons
tend to snag about half way thru and I have to remove the old ribbon half and
attach the new to make the ribbon work.
I'm trying to find a driver for the Juki to install on newer word processors.

God bless you John!
Mine has just started having paper getting stuck on the "teeth roller"
underneath the larger one next to the green felt "hot" area. It needs a new
smaller roller cause worn out. There are a number of rollers that look like
this, how do I tell which one it is in order to order the right one?
Thanks very much.
Somewhere down the line I'll return the favor.
