Bad form to follow up my own posts, but me and Mr. Multimeter took a look
at the fuses on the PU8 board this evening, together with the diagrams on
<http://www.totalpsx.freeuk.com/html/fuses.htm> and we found some very
interesting things.
Fuses PS605 (fuse C) and PS602 (fuse E) were both blown. The web page says
that if PS605 is blown, then there will be 'no joypad operation' but my
experience and that of Paul Irvine
(Message-ID: <qagdOI4TW0X1lv...@4ax.com>) suggests otherwise. The
web page also says that PS602 is unused in European PlayStations, but if
that's the case, why is it blown in mine?! If it's not used, there will be
no current passing through it and it should never blow, right?! :)
What persuaded me to take a look was finding that my new cheat cartridge
didn't work either (and did on another PlayStation) and I really /need/ to
cheat on some of my games... :)
Perhaps PS602 is related to powering the Dual Shock motors and both the
Parallel AND Serial IO ports? That would explain someone else's post stating
that he'd replace PS605 and regained joypad function, but had no Dual Shock.
I've crossposted to sci.electronics.repair in case the guys there find this
interesting and/or can comment on my hypotheses.
Best Regards,
Alex.

Yet another followup -
It turned out that it was the 800mA fuse PS602 which IS used in European
models to protect the 9v unregulated circuit used by both the Dual Shock
motors and the Parallel IO port.
I've now replaced it with a quick blow glass fuse with a couple of leads
soldered to it so that I don't need to solder to the PSX motherboard if it
blows again. I'll make sure that I don't make the same mistake the previous
owner obviously did. Still, not bad for a 69p repair!
Cheers,
