Love the Michaelangelo reference. I'm curious as to how many others on the
list got it. (It's carved into the strap on the Pieta. Apparently when
it was first put on display, there was some question as to who'd made, or
something like that.)

Hi,
Please remember ... TRIM YOUR DARN POSTS!
No one needs to see a hundred+ lines of quoted post just to see
a one line reply, no matter what kind of sandwich it was!
(And, the guy getting the sandwich had the better deal, IMHO :)
thanks,

Hi,
Offered these in a post last year.
1) VAX DATATRIEVE Reference manual AA-K079E-TE
(this is online but version KE079G?)
2) VAX DATATRIEVE Handbook AA-W675B-TE
(Does not seem to be online? Willing to scan)
3) VAX DATATRIEVE Guide to Writing Reports AA-P862C-TE
For Datatrieve version 4.1
Versions online seem to be for version 3.0?
Willing to scan

"George Dragner always wore a belt with a metal dragon buckle. He was a colorful character known for pissing off management. His most
famous act was tossing a chair through the window at a customer site. The customer refused to believe that the lack of humidity in the room
was screwing up his magnetic tape media. As the tape heads depend on the moisture from the air to prevent the magnetic oxide from being
torn off the media from the friction during a rewind. George broke the window to prove his point. He was right ! "
There is a minimum RH specified for tape, but "tape heads depend on the moisture from the air" ??

It's not heat. Just some rubber types degrade chemically over time. Cross links between the long
chain hydrocarbons break, and the solid turns to a semi-liquid. Very sticky liquid.
I presume the body of your eprom programmer is painted metal or plastic. So 'acetone and hot air' - NO!
The gunky stuff is not terribly soluble. Mineral turps on a tissue pad, rubbing, kind of works.
Mechanically scrape off what you can first. Use wooden or plastic spatula to avoid scratching paint.
The rub with the pad. Solvents like turps, acetone, IPA etc - always try a little on your surface first
to check the material isn't damaged by the solvent.

Hi All,
I have an EP-1 eprom programmer from BP Microsystems.
The rubber feet melted. It was in my closet. I have no clue how it got
that hot, or if they
are just some composition for them to melt.
My question is how do I clean this up? Acetone, paint thinner? I scraped
off the feet, so there is
just a few 'streams' of melted rubber down the sides, and a bit that
somehow got inside (also on the side, not on the electronics).
Just looking for some ideas before I start applying chemicals...
Thanks,
Kelly

It is probably not heat that melted the rubber. It?s likely degradation.
Some rubber parts get dry and break, some parts sort of ?melt? and
turn into this sticky, nasty glue.
You already got some hints on how to clean this, but if you are nervous,
you could start off with just isopropanol (that?s the main ingredient
in disinfectant). The advantage here would be that you can?t harm
plastic or electronics with that. You could use the common medical
grade disinfectant, just don?t drink it ;-)

I've been helping dreamlayers with his cleanup of the NetBSD/Linux
mopd, ( https://github.com/dreamlayers/netbsd-mopd ) and we were
looking at how it handled different a.out MOP files, specifically
where the files may be little endian
For non MID zero files its easy enough, but little endian MID 0 files
are potentially more complicated.
https://github.com/abs0/netbsd-mopd/commit/6ab8555817f3dff23c506464d302d1a4…
It can netboot Ultrix and the vast panoply of NetBSD MOP boot files in
the various a.out and ELF incarnations http://mop.absd.org/netbsd/
(those that are not broken that is :/ )
I was wondering if anyone had links to hand for any other good sources
of MOP files?
Thanks
David
