Some people on the net expressed interest in anyone who has purchased a
Micro Express 386SX-16. Well, I've had mine about a week now and even though
it took me 9 weeks to get it (pretty much as promised by them), I am glad
I ordered theirs. For $1935 (includes shipping) I got the 386SX-16, 2M mem,
100M HD, 1.44M and 1.2M floppes and TVM VGA monitor. I have yet to phone
their tech support line so don't know how good that is. One thing that they
could have done better on was documentation. All I got was 20 or so pages
of setup instructions in a small 3-ring binder.
Below for your consumption are the PC Mag Benchmark Tests that I ran on it.
