Hi everyone,
I recently acquired a Japanese PS1, 7000 series of unknown history and unsure what, if anything works on it. I don't have a step-down transformer currently and it will be a couple of weeks before I get one (I'm in a 240v territory).
Being an impatient sod I'd like to get something rigged up for testing but I'm not sure how to proceed. The way I see it I have four options:
1) use a bench power supply to deliver 8 and 3.5v to the system - but I'm not sure how the switched 3.5 works on these - is it OK to just provide the 3.5 unswitched and it'll power up?
2) My main PS1 is EU but is a 1000 series so the PSU pinout is different - is it OK to just provide the required pins from the 1000 PSU to the 7000 board and leave the two others floating?
3) hack the Japanese PSU temporarily with a 400v bulk cap. From what I can see this would most likely work (the PSU would just drop the duty cycle to service the lower voltage) and would only be for a short period - is this in any way acceptable? I understand that it is sub-optimal and I would not leave it that way or
4) be more patient you numpty
Which of these would be the preferred option here?
Thanks for any comments!
