The pdp-11s were Gove by the time I got to tech in 85 I think
I wonder if those date to the first time I visited, where the PDP-11s
were still installed :-)
Are there still T-shirts available? Mine from that trip is trash :-)

Not to complicate the haunt for the first Altair, but there is no guarantee
that it ever existed. Maybe it was an urban legend that it was shipped. If it
did, did it work? Might just buy the remaining issue of Popular Electronics
featuring the fake Altair.

Eric,
More than happy to send a reel or two your way.
Just give me some information and I can make it happen.

I have an SEL 810A operating, which some of these tapes were likely written
with. If any of the tapes are labelled I can quickly identify if it is an
SEL product.

A mostly similar variation has it that they shipped the unit via Railway
Express Agency (remember REA??) and as the story goes, it was in
transit when REA closed their doors unexpectedly and with no warning,
went bankrupt.

Everyone lost the metal strip! It's sandwiched in between the trim of the outer
case and the dress panel. Some folks stuck it to the dress panel with glue,
double-sided tape, etc. Those are usually the machines which still have the
metal strip.

I see some altairs have a metal escutcheon on the bottom with the stylized
words "MITS ALTAIR 8800 COMPUTER" whereas others, the front panel is just the
dark faceplate top to bottom. What is the difference? Would one have been a kit
and the other sold fully assembled? Or maybe later units vs ear

It would be useful to know what systems these tapes were used on.

Hello,
I'm an employee with the National radio astronomy observatory here in Socorro
New Mexico.
As part of our NGVLA upgrades, we are seeking to get rid of old data tapes from
the tape reel days of Computing. These contain things such as the boot loaders,
OS, specific collection programs and a
