I have a small, 5-20 stack of 16 mm's of movies dealing with computers
The one in front of me is
"Once Upon a Punched Card"
I am looking for a place in the USA with a reasonable price to have them
digitized and I will place them on both my Google drive and a Youtube
So far I have only been able to find places I can not afford.
Suggestions, Ideas, etc ?
I'm about to acquire a couple of 1980s-vintage military surplus AN/UGC-137A terminals (i.e., glass TTYs with some local message preparation and storage capabilities) which have a bubble memory subsystem. They use plug-in cartridges containing 256 kbytes of storage in the form of two Intel 7110 1 Mbit bubble memory chips and their 7242 formatter/sense amplifiers.
One of the cartridges contains the one and only copy of the terminals' firmware, which I believe they need to load up at each reboot. Naturally, extracting the contents of that irreplaceable cartridge for archival, and potential future emulation, is going to be a very high priority for me. I have a few different approaches in mind for accomplishing that. One approach would be to remove the two memory devices from the critical cartridge in order to dump their contents in an independent bubble memory subsystem.
With that in mind, I'd like to get my hands on a working Intel 7110 bubble memory subsystem, or the parts to build one myself (i.e., a complete 7110/7220/7230/7242/7250/7254 chipset that I could make a board around).
Might anybody here have what I need available for sale or trade? I might be able to use some arbitrary old computer or other device that has a subsystem based around the Intel 7110, or a development kit such as the Intel BPK-72, or a chipset to make my own board.
If I can't acquire or make the hardware to dump the memory chips outside of their native system, then I think my next option would be to passively snoop the host bus interface of the Intel 7220 controller I expect to find inside the terminals as they perform their initial firmware load, so that I can reconstruct the cartridge contents from the trace data.
The terminals were made by the Librascope division of Singer, and brochures can be found here:
I already have the critical cartridge in hand, and I posted some pictures of it on Twitter:

Recently, I?ve started working on a Canon BX-1 machine dated 1977.
It was CANON's first standalone business / home computer featuring I guess the Motorola MC6809 CPU, one line of gas plasma display a thermal printer and 125k floppy drive.
See pictures here: https://drive.google.com/open?id=1rT4qwtiR68AN5DRqoCwjxGDJvRRdlHha
In working condition but without manuals or disks. Only little can be found for this machine, its not listed in http://www.bitsavers.org/pdf/ nor https://amaus.net/static/S100/
Also http://archive.computerhistory.org/ isn't mentioning the machine.
So I would be happy, if anyone can help in disk images or manual scans (manual front pages are shown in the picture link above)

96 col cards were the standard on the later 1700's
I had full access from midnight to 7AM but the shop was window only
until the next night.
Turn around time during the day could be as much as 4 hours.

I have the IBM 360 aluminum plate that goes on top, it is scratched. More
detailed and better pictures as I dig deeper.
For shipping a I will have professional box built by a friend who's hobby
and restoring furniture.
Price to be determined and will go into my estate.
If interested please email me directly

What about mutt do you prefer over alpine?

XT2190s, XT1140s, some of the early ESDI disks...
I have 6 XT2190s at home, and maybe one of the damn things works.
Does anyone out here know, beyond speculation, what some of the common
failure modes of these drives are? I'm not opposed to open-HDA surgery.
And I probably won't do anything.
But the question of WHY this line of drives in particular sucks so much has
haunted me for some time...

Hello, all -
Has anyone run across the subject system - a mid-90s Motorola '030-based
document scanner/retrieval system? KV-F520 seems to be a model of the
unit, along with LF-7300A or LF-7304 5-1/4" MO drives. I have a hold of
some media that I can read, and can see the moral equivalent of files in
Panasonic's own format - I suspect it's thinly veiled TIFF or maybe a
capture format of their own making. Has anyone else run across this before?
