Hi, a heads-up on sending expensive items via FedEx. They appear to have a new
policy, limiting honouring insurance coverage; so, in my opinion, they are
now unsuitable for shipping valuable items.
Data point 1: a couple of months back, I bought a PDP-11/40 on eBait. It was

I suppose they still charge you an insurance fee according to what you declared
as the value?
This seems like a pretty clear case of fraud, and you should report it to the

One thing not discussed (maybe it doesn't occur in audio) is that there

Bill, I have one of the models (not sure which one would have to climb around
in the warehouse of these http://www.baudot.net/teletype/M43.htm From memory,
it looks like the M3450. Welcome to borrow it! But it could also be one of
the others on this page

Out of curiosity has anyone tried running tapes at different temperatures,

So I got the RX02 drive up and going with the RXV11 controller. Man it's

This talk of old tape brings up a question that I wanted to ask the list.
I've run into some tapes that say they were prepared on the IBM DCS

I confess to never having run into the 7044 in real life--it always
seemed like an odd machine--basically, a 709

I have run TSX+ since the early 80's. I developed a few handlers to

Nothing like like an J-11, 4Mb and a hard disk to make a excellent
