Subject: My first good find!!!
I'm currently in a very good mood because I've found a Jupiter Ace in
near-mint condition, complete with 16k RAMPack, intro tape and a
copy of the book "Jupiter Ace FORTH Programming" by Steven Vickers. All
this,
including the polystyrene box for the rampack (and
rampack instructions)
cost me the
rather feeble sum of two British pounds.
Nice one! I wonder if that book is online somewhere since it's the only
thing I haven't got.....
Now, there is a catch. The machine didn't come
with a power
supply. So,
can someone with an Ace, working PSU and a multimeter please tell me what
the polarity and voltage of the PSU's output is? I'm hesitant to power up
the Ace in case I end up fouling up the settings, with fairly predictable
results.
Tony's not far wrong with his guess (as usual :). The PSU I have in my
sweaty mitts here says 9V 800ma and I've tested centre (tip) positive. I was
going to say you could get away with a ZX81 PSU but they're 700ma and the
ZX80 is 600ma. Oh, the voltage I got was ~14V so it requires a load to bring
it down to 9V.
cheers
