 Below I will give a turbocharging diagram for the Z-80. This article was not written by me,
therefore, I don’t claim its authorship. I don’t know where it comes from. But I
I thought that for those who have not read it, it would be interesting to look at
diagram. To make it clearer, I won’t write anything more from myself,
let everything be as it was:

ATTENTION: When "turbocharged", expanding memory, etc. alterations
We advise you to consider turning off all these “baubles”, which
then don’t be offended by programmers who don’t count on it
that your computer seems to be no longer quite a ZX-SPECTRUM. Of course
very soon the body of your “mutant” will be littered with “micriks”, but
but one day you will put them all in the "ON" position
and join the INTERNET!!!

На плате нужно сделать один разрыв. Проводник, идущий на 6 вывод
Z80 нужно оторвать и подать его на 2 вывод КП11, а на процессор
подать сигнал с 4 вывода КП11.
