Life is strange...
Instead of working on USIT Athena I just acquired one more "patient".
It's the perfect example of second generation laptops, which shaped this class of machines almost to a modern form, at least as far as we speak about form-factor.
Well, actually these were first really "massmarket" machines if we only can say this about a machine which costed $4185 in 1991 (more than $9000 in today's prices).

This is a light (lightest if we trust PC Magazine'91 review) and small machine, which has 386sx20 CPU, 2 Mb of RAM and 42 Mb HDD (at least mine has such disk).
Screen is 215mm (8,5 inch), b/w (32 grades by spec), VERY laggy although produces clear and very useful image. Definitely this in neither graphics nor gaming laptop. External dislpay is not supported. Communications include Fax/Modem (in optional bay), external FDD, LPT and COM-9 - thats it!
Of course, you can run WIn3.11 (and it was installed on this machine), but 2 Mb RAM is way too low. So, this on is, perhaps, a pure-DOS machine for rich journalists (keyboard is just perfect!), programmers/developers etc.
Interesting that RAM is installed via full-size 72-pin SIMM: 72-pin in 1991! and 72-pin for 386SX as well!
