Yep. 5V LSTTL.
Not suprising...
I've found that rewireable mini-DINs are
significantly larger tham=20
moulded ones. Quite often the former won't fit.
I have a couple of solderable mini-DINs, and you're right, they're far
too big. About twice times the length of the plug on the PS2MouseMini,
and a good 5mm extra diameter.
IIRC, they won't fit the mouse socket on the back of an A300/A400
leybaord either, at least not without cutting them.
My A310 came (second-hand) without a mouse. At the time, Maplin sold
quadrature mice as spares for the ST and Amiga (one was 2 button, the
otehr was 3 button, and they had different connectiosn to the DE9 IIRC).
So I bought the 3 button one of those, cut the DE9 off and soldered the
wires to a 9 pin mini-DIN ARGH!. What made it even more ARGH! was that of
coruse Ididn't know which way round the quadrature signals had to be
(wich is X1 and which is X2, for example), so I had to swap over a couple
of pairs of wires. Moving wires in the mdidle of an already-soldered
mini-DIN is a lot worse than DMD rework :-)
The A3000 will take a moulded mini-DIN plug *and that's it*.
CJE apparently have spare mouse cables, but they're not much cheaper
than an entire mouse :(
Price for a new mouse? =A343. No, there isn't a missing decimal there, I
asked.
Ouch!...
I did find a CPC-branded 'replacement' mouse for the Archmedes in a
chraity shop many years a go, No, I am not sellign it :-)
This will annoy you, but my WHitechapel MG1 came not only with the
original Depraz mouse (misisng some of the buttons -- Digitast rocker
button swithces on the front), but also with an Acorn mouse that had
had the 9 pin mini-DIN cut off and been rewired to a DE9 plug to fit the
MG1. I repired the original mouse (I had some suitable switches in the
junk box, and the buttons just clop on) but of course I also kept the
Acorn one. But it's no use on an Acorn machine any more.
3) Remvoe the darn mini-DIN socket fro mthe PCB,
fit a DE9 or similar=20
on the case and wire it up. %deity do I hate mini-DINs...
Actually, I could probably route one through the back. There are some
pads on the board marked "ALTERNATE MOUSE" which appear to connect to
the mouse socket. I'd sooner hide a PIC micro and a PS/2 socket inside
though. Get rid of the external adapter entirely :)
Are those pads at a suitalbe spacing to fit some kind of plug to the PCB
(e.g. a Molex KK)? If so, fit it and make whatever plug-in adapter you
need...
It's still just about the worst connector they could have picked... :-/
I agree. I hade mini-DINs, They are painful to wire, and don't make good
contact even when new. Are they really a DIN standard, or are they named
miniDIN simply becuase they look like a smaller version of the well-known
audio conenctor?
