I suppose we could do the math if we had enough data about the
reliability of each. There's more bytes in the LTO basket,
but a lot more baskets needed if you want to store the same
amount of data

I once rode on an USAF general's jet with a load of 844 packs. That
probably was pretty good bandwidth for the time...

I didn’t realize they were 48-bit, though I seem to remember them being 24-bit.
The system I used was more “logistics” and general purpose ADP. I spent a
*LOT* of time using the MUSE word processor.

I almost remembered, had to look it up to confirm 81, the 48bit system
they carried on when they bought the original company that had made
them and the Vulcan OS. Not a bad scientific and instrumentation
machine. What was the original company Datacraft or something?

Slash 6 or one of the other 24-bit machines they made?
any of the tapes for the OS

A bit out of your range, but if we can figure out

Hi friends,
I've been building up a nice little PDP-11/23+ with cabinets, RL02's etc. To
really round things off, I'm looking for a open reel-to-reel style 9-track tape
