By the way . . . it might be desirable to find an appropriate site on which
to post this stuff for general use. Where's the most appropriate site?

Several of these documents have very detailed graphics (line-art, mostly)
which may or may not scan well. I would not like to have to re-create the
exploded view assembly drawings. Though I have a scanner and some really
quite excellent OCR software, I've never been able to deal well with highly
detailed line art. The typical FAX scanner at 100x100 pixels per inch would
not render these drawings in any useable form. Even at 200x100, which is
the best I've ever gotten from a FAX.
Emanuel Stiebler has offered to handle this with tools he has in house.
I'll see what he and I can work up, as he and I live in the same geographic
area.

Perhaps that will be the way to make these items available to those who need
them. I've had several requests for one or another of these documents in
recent weeks. This may turn out to be somewhat of a headache, as some, e.g.
the SIEMENS documents, are still in the form of a booklet, and, having been
wet at one point or another, it may be desirable to scan them and reduce
them to text as opposed, simply, to preserving the graphic images. This
will mean the graphics need to be repaired in some way as well.
Apparently, as people try to resurrect their ancient computing hardware,
they find some of it is in need of maintenance. Mine certainly has turned
out that way.

Well, in *this* particular case, Mentec arranged for Andromeda to
give me a SCDC controller with some SCSI drives and 5.25" and 3.5" floppies,
and that's the reason why the Andromeda is supported for this operation
under RT-11 5.7 :-).

Not necessarily. I just hooked a true DEC RX50 to my SCDC, configured
it, and it still lets me do a RX50 format:
SCDC User Service Port V3.06
B Configure controller HARDWARE JUMPERS
D Display/define physical DRIVE PARAMETERS
A Assign logical DU/MU UNITS
C Configure controller SOFTWARE OPTIONS
E Exercise a SCSI DISK drive
F FORMAT a DISK drive
P RESET controller and EXIT
? d
SCSI or Floppy (S or F)? f
Floppy drive number (0 or 1)? 0
Floppy drive 0: 800 blocks
Floppy drive types:
76 3.5" 80 track DS
134 5.25" 80 track DS
420 DEC RX50 dual drive
Floppy drive type (76, 134, or 420) [134]? 420
SCSI or Floppy (S or F)?
SAVE CHANGES- Are you sure (Y or N) [N]? y
SCDC User Service Port V3.06
B Configure controller HARDWARE JUMPERS
D Display/define physical DRIVE PARAMETERS
A Assign logical DU/MU UNITS
C Configure controller SOFTWARE OPTIONS
E Exercise a SCSI DISK drive
F FORMAT a DISK drive
P RESET controller and EXIT
? f
SCSI or Floppy (S or F)? f
Floppy drive number (0 or 1)? 0
Floppy drive 0: (offline)
Available floppy formats:
DD 800 blocks
Which format (# of blocks)?
Now whether you want to actually do the format on a DEC RX50 drive is
another question. According to Charles Lasner's voluminous posts on RX50
technical details, RX50 drives lack the required physical head-positioning
accuracy to make a RX50 floppy that's guaranteed to be interchangable with
other drives. Look at Charles's posts to alt.sys.pdp8 on the topic
>from 4-5 years ago for more details about his tests.

They are definitely worth saving. Many people don't have access to these.
Fax the pages to your computer with a regular fax machine. The full version
of Acrobat will convert many fax images to PDF. I know there are several
other programs that will convert too, but I am not sure of their names. I
have an old DOS program called Hijaak Pro that converted between many vector,
raster and fax file formats. I looked and it is a pre-PDF program.

Hi!
I just started an auction on Ebay for Nicolet
Model 824 plotter. Item # 113397200, closes
6/14/99.
I'd like to add some specs to the description.
Can anyone fill me in on this oldie? It accepts
24 inch paper and emulates HP7475; that's about
the extent of my knowledge. Direct e-mail replies
appreciated. Thanks.

Regarding my prior message, I stand corrected...
But even though an RQDX3 is not required (or useful) for this, I'll
suspect an RX33-type drive still is. Is that correct, Tim?

Hello
I have 2 Kaypro II machines (were working when retired to attic about 10 yrs
ago) and a Kaypro LQ Printer; do you know of any market for these or of any
people anywhere in the world (missionaries, 3rd world schools, etc) that could
use these reliable if outdated by internet standards machines?
It seems a shame that these could be not be used by someone who can't afford
or need to get into the current technology mode. Please send me any leads
you may have.

RX50 formatting under RT-11 V5.7 (i.e. FORMAT/SINGLE DUn:) only is
supported on certain 3rd-party controllers like the Andromeda ESDC and
SCDC. It doesn't work with RQDX1/2/3's.
