After reviewing the domestic clone of the IBM-PC XT and his Italian colleague, I would like to talk about another machine from the IBM PC family. This time it is unremarkable, the most common HT-ha. It is because of its usualness, I would even say, consumer demand, that it occupies a certain place in the collection. This PC is already assembled not in the form of a candy bar, but in a more familiar design to us - it consists of a system unit and a separate keyboard. To display information, not a household TV is used, but a computer monitor.

When you press the TURBO button, everything becomes exactly twice as fast. Video memory test:
In general, here is such an interesting, albeit quite ordinary machine. Please write your comments and suggestions in the comments.
