The IBM PC Portable - not so portable at 30 lbs!
this is just slightly more advanced than an XT motherboard thrown
into a plastic shell with PC Powersupply and keyboard. That's pretty
much what it is!
When you have a
look at one of these things, the first thing you notice is at the
back, there is a keyboard port in the rear, exactly where the XT's
is, but it has a keyboard cable plugged in, which runs to the port
on the front of the case.
But it's a nice
thought, and strikingly similar to the first Compaq Portable.
