Fixed everything! There are no more loading delays. Both floppy disk drives work normally. Thank you very much, @sergey, for your projects. I have already repeated many of them, I had great pleasure. It's like being in a student dormitory again 35 years ago)

It is interesting ! I will try to check it tomorrow! It will even be funny if the PS/2 mouse turns out to be the cause!

Good day ! First, I'm showing off a little: I finally assembled Kh8088, which had been working for a long time, into a case. For some reason, I love 19" cases))) In the photo: Xi8088 by skiselev, CGA Redux by hkzlab, OPL2 and FDC by skiselev, VCF XT-IDE Rev 2 and ISA Backplane by Alexandru...

The problem is solved. Replacing a few chips with a 74S (K531) helped, the board works flawlessly. I still don't understand why it didn't work when I used 74F (K1531) chips in the same places...

Good evening ! This is my first post on this forum. I apologize in advance if my questions seem ridiculous. I haven't held a soldering iron in my hands for 30 years)). But now (after two Z80 projects) I have built a xi8088. Not immediately, but it worked! Almost completely assembled on...
