What is this?
DannyTheGhost:
Okay, let's say I saw this board already somewhere... right, in my "old stuff" box in my office ;D
It is linear power supply.
It outputs +5V, -5V and 12V.
Dont know about its current capabilities, but transformer is rated for ~60W.
black ICs - discrete logic chips that gives button switch "EN" function and some basic control like short-circuit protection.
Those hybrid goldy ICs - according to its part number - linear regulator with regulated output rated for 150mA
If you want any more description about this board - you will have to wait till Monday, when I will be able to get to it

Ceramic ICs look like 142ЕН1, 142ЕН2 VREGs. https://eandc.ru/pdf/mikroskhema/142en1_142en2.pdf
