Such an incredible collection, wish I could have visited years ago in its
prime presentation. So many great artifacts, at least fairly certain
they'll go to good homes.
The LINC-8 and Micral-N in particular appeal to me - but I'm in no position
to bid on anything this year.

It's also worth noting that the PC memory space is very much *not* divided
into fixed 64KiB segments (and ISTR it was originally a 512/512 split).
Segment registers have 16-byte granularity and a segment can straddle a
64kiB boundary just fine.

Ben,
The purpose of the stdint.h file is to allow the programmer ti specify
the size of the variables.
On some systems is an int 32 bits or 64 bits (or even 16 bits on older
systems or 16 bit micros). The size of an int is not specifically
defined in the C standard.
Especially when doing
One was on ebay and sold a while back. They're more common than a LINC or
Varian mini,etc.

Why? I know of at least four in Europe, but there are more I think. And
then all the LGP-30s in the US (are there any functional ones BTW?)
One of the Europeans is ours ;-)
