I also needed power on/off switch just for convenience. I’ve removed all unnecessary cabling and secured remaining cables inside. PSU after unscrewing top cover looks like this. Standard procedure was involved (I don’t have all photos though) which is cleaning, applying solder and removing solder surplus with a soldering wick then reapplying a thinner layer of solder.Ĭuriosity time: I was kinda surprised when I saw an SMD chip mounted in a wicked but cool way. Without it cleaned I wouldn’t be able to test my setup since only hardware to load stuff on a speccy that I have is Divide2k14 by Lotharek. Soooo to work!įirst, I had to disassemble this unit to sort out an expansion port. The power socket in this speccy is a simple DIN-6 and I already had these plugs ordered for a different project (external SD2IEC). PC PSUs has a lot of various voltage lines and -12 V is there as well, along with +12V/+5V. I was like hmmm … hmmmmmmm … and all of sudden I came up with an idea to use cased PSU from a small PC that I’ve disassembled a while back.Īt least it sounded brilliant but was a bit harder to achieve … KK not horribly hard after all ? That’s the one with Amstrad mainboard.Īfter a short research, I already knew that in addition to +5 V and +12 V, black +2 requires -12 V line for normal operation. … So, I’ve decided to take my work back underground … to stop it falling into the wrong hands …Ī friend of mine, V-12/Tropyx, asked me to hack a PSU for his ZX Spectrum +2 – Black. … but DAMN, there’s no atomic power plant nearby.
