Power source!
ZXNet echo conference «zx.spectrum»
I greet All and want to talk to him about 'Power source!':
Long life and prosperity to you, All!
People!
This is the problem. I have a timing belt. I attached 512kb to it. There was a shortage of power from the MC9016 unit. The foreman who did this tinkered with the block, everything seemed to work, but after 15-20 minutes the doctor started swearing at some addresses. I grabbed it all and took it to the master. Everything is OK there on his power supply.
Next, I connected the power supply from the EC1840. About 1.5 hours of work pass - simply indescribable glitches begin, and before that everything was perfect. Moreover, the drive(s) are powered
from another source and if you connect them to the same one, which is connected to the computer, then the same
glitches after half an hour of work (garbage on the screen depends on the cursing of the doctor every
time in different places).
What to do?????????????
Where can I get a normal one? BP?
How to cut off the PTsshny (in the sense of whether it will start?) ?
People! Please answer in more detail...
Sincerely, Nickolay Zabrodotsky AKA ProfeSSor F0lken

A piss block is perfect. It has been working perfectly for me for 3 years now.
Konstantin will connect it.

Long life and prosperity to you Alex!

If you use 9016, then the glitches are from the same address, and the test for RAM drain on different addresses fails... But in 128 mode everything works like clockwork even in turbo mode.
On the block from EC1840 everything is OK for 40-50 minutes. Then - a complete collapse - garbage on the screen, system reset, left attributes, etc... And regardless of the mode (128/512). The doctor is finally going nuts.

Something is wrong there. Strange things are happening. What is Konstantin saying?

I gave him a car with a 9016 power supply unit to connect a Kempston mouse. So he
will look at it, and then I’ll get the PC, etc...
But in general it’s sad...
