Hi Jim,
Greetings.
I purchased a couple weeks ago a metal box full of
unit record docs, forms and cards ($20). Including
Ramac 305 guide and manuals for various collating,
punching, as well as some training manuals. I'd be
happy to have it go to a good home. I've got a
spreadsheet with more details I can send on request.
The box full is very heavy so I would a pickup in the
San Francisco Bay area.
.
Thanks, Jim
Bitsavers.org would very good home for these IBM manuals.
Regards Henk
IBM collector

New subject: Looking for 0.75" width endless printer ribbon
Hi,
I am searching for an endless printer ribbon with
a width size of 0.75" (19mm) to replace an worn-out
IBM ribbon that is not available anymore.
Anyone any idea on a good subsitute ?
My idea is to remove the ribbon from the subsitute
and replace the worn-out one in the IBM cartridge.
Thanks for your replies.

Ribbons can be reinked - if you can find a vendor
nearby that still offers this service.
I would think that easier/safer than trying to remove the
"good" ribbon and hopefully manage to make it fit into the
shell for the old ribbon (maximum entropy in ribbon
packing :> yet, you still have to hope your new ribbon
isn't too long to fill the space available!)

You didn't say what length is required. However, there is a readily
available HP ribbon cartridge with a 3/4" endless ribbon that is about
40-50 yards in length. It fits the HP 2932A printer. Nu Kote markets it
as the BM 353.

That should work, it is way too long, and most likely will refill 3 of the IBM
cartridges.
The trick will be to make a heat sealer to melt the ends together to make it a continuous
loop again.
But we are working with nilon, it melts easy.
I am working with the same cartridges as Henk is. I was looking at building a reinking
system, while he took the
replacement approach.

I believe that nylon ribbons are welded ultrasonically. Long ago, one
used to be able to order ribbons made-to-order.
I have a re-inker made by PBM that I would be willing to part with. It
uses a small synchronous motor to slowly drag the ribbon over an ink
reservior equipped with very small holes through which the very viscous ink
"leaks". A very very messy operation, but it does work. It's set up to
work with aforementioned HP ribbon. IIRC, the ink is much more viscous
than that used to re-ink rubber stamp pads.

I have a reinker for epson ribbons somewhere around here.
The problem with these ribbons it there is no drive roller in the ribon cartrage like the
hp or epson ribbons.
These ribbons get stuffed by a pusher that is part of the printer itself.
I am sure everyone is now confused, this is a printing head built in to a card punch and
prints the human readable text on the top of the card as it is being punched.
The reason it is 3/4 wide is there can be up to three lines of text on the top of a 96
column card.

Just to follow up on this....
You are correct and they still exsist, thanks to ASK.com I located a printer ribbon
company that can ultrasonically weld 3/4 ribbon, I am sending them one to refill
next week.
Till later ...

New subject: group buy for homebrew CPUs ?
Something like this: http://www.anysystems.nl/hjs22.html
This microprogrammed TTL CPU and IO unit where build by me in 1976/77.
Regards Henk.
I was wondering if there's anyone else out there
interested in someday
building a Magic-1 and/or D16 homebrewed CPU computers. If so, I'd like
to organize a group buy for some of the harder to source parts.
Specifically, the 74F382 and probably 74F381. My favorite chip broker has
a $50 minimum order.
