I present to you another review of a retro computer - this time a clone of the IBM PC AT , aka 286, aka "deuce". Despite the fact that this is a clone, it is almost one-to-one, right down to the arrangement of the microcircuits on the printed circuit board, repeats the original IBM 5170.

As you can see from the tests, this computer is only 3 times faster than the original IBM PC, 23 times faster in mathematical operations and more than 2 times faster in video subsystem. And it feels like it slows down only slightly less than HT-shki. Well, really, what else to expect from a processor with a frequency of 6 MHz.
But this is already 286! You can plug a VGA video card into it and run a much larger number of toys and various programs. For example, this is what Block Out looks like at EGA.
That's all I wanted to tell you about this exhibit. Please write your suggestions and comments in the comments.
