Might as well hammer nails through them. "To keep the heads properly aligned
on the tracks, it used a servo system driven by servo data written on the pack
(along with sector headers) at the factory. Packs cannnot be low-level
re-formatted in the field".

Often for data input one could use over strike characters for input. Not
EQ might be = BS | Did any video display terminals
repeat the same effect?

Hi all,
I'm hoping to get an answer here.
The 8625 barcode printer has a prompting mode, switched on by activating
the bottom switch in a bank of switches. The printer is then supposed to
write a prompt, so you can start programming the label formats.
I seem to remember that the printer expects a CTRL+H sequence to be
reset/restarted, but nothing happens.
Can any of you remember the settings for the terminal (I do know about
9600,7,1,even) ? I'm not sure on which terminal the printer expects to
write to. VT100 ? ANSI? ? And how about flow control?
Any help would be appreciated
Regards
Nico
PS The printer is to be used for museum purposes, and as usual, the
museum has no money to spend :-(
And one more thing,
Am wondering about the possibility of setting up an interface between
modern Unix email and the embedded client for cc:Mail on the HP 200LX.
Various versions of cc:Mail are available from archive.org and
vetusware.com, but the missing link seems to be the "client" type
connection from the cc:Mail post office to the internet, i.e. for the
PO machine to connect periodically and collect mail, rather than just
acting as a server.
Have not been able to find much technical information about cc:Mail. I
did see a Lotus development kit for sale somwhere but seems to have
lost the link.
Does anybody here know anything about this? Are there any books or
technical documents on cc:Mail available anywhere?

I ran across a reference to this on FB.? It appears to be from 2008, so
may be well known or obsolete material.
The other interesting info at the end of the article is the contact name
and info about someone who restores or works on tape heads.
Might be interesting to at least contact and ask if he's still around
http://www.wendycarlos.com/bake%20a%20tape/baketape.html
Contact John French, at JRF Magnetic Sciences (973-579-5773) for further
details on magnetic tape head restoration and storage, and other related
services and products.
FB page with the info.

The fellow who does a lot of tape recorder (reel to reel) repair has a
FB group worth dropping in on.? This is the link to a photo with a
pretty bad Ampex head.
thanks

Last time I was at the Living Computer Museum, I talked to the guy restoring their 370 panel, who was using LEDs, because the original bulbs are all but unobtainable and do not lave a long service life. This is likely to be something you end up needing to approximate with modern components.

I'm listing this stuff just in case someone is desperate for
any of it.
All items are as-is and free. Pickup only here in London, ON.
I'm too old and too tired to run around shipping things.
I'll hold on to this stuff for a couple of weeks; after that it's
the recycling bin.
