Containers 1-2n.
Hang on D53, legs 14 and 12
I.e. 2 conders - one leg on the m/s, the second on the body.
ALTER will have outputs _like_ like 4 and 5.
(They are on D53 and go - so you can use them as a guide)

Once again I ask for help with advice. Maybe at least this time my request
will reach those who know the solution to the problem.

So, there are:

1. Yellow trumpeted Scorpio
2. Zonal keyboard and mouse controller
3. SMUC
4. System connector expansion board - tee
5. ProfPZU
6. Regular ROM

I. In configuration 1+2+6 everything works fine
II. In configuration 1+3+5 everything works almost normally, but after some
time TURBO
III turns off. In configuration 1+3+4+5 everything works, but TURBO turns out even faster
IV. In configurations 1+2+5, 1+4+5, 1+2+4+5, 1+2+3+4+5 - the computer hangs and behaves completely unpredictably, especially if you press MAGIC.

Now (for more than a year) I’ve been working in configuration II and putting up with the lack of
TURBO. However, I would like to have 1+2+3+4+5 without glitches and with a working TURBO. Let me note that at first 1+2+3+4+5 worked, but TURBO did not work initially, and then
after trying various configurations, the computer flatly refused to work with
the keyboard controller and ProfFRAM (something burned out?).

I know that the absence TURBO is treated by hanging a capacitor on some legs of ALTERA, but I don’t know what capacity and which specific legs. But I don’t know how to make the computer work in the 1+2+3+4+5 configuration. Help
please. Thanks in advance.

Spectrum Expert and see how Lomov’s tree is assembled.
Make a similar one for yourself instead of Zonov’s and stick all the devices *only into the tree*!
