Hi,
Has anyone successfully built one of the PS/2 -> Indigo adapters off of
the following page?
No, but I've seen that page before - lack of a PIC programmer has
stopped me building one (or two). We've got a 4D/25 and two Indigos, but
only one SGI keyboard between the three...
When I hook my scope up to the clock and/or data PS/2
lines, I see no
data being received from the mouse.
Obvious one: have you checked that the mouse is getting power?
I don't actually know whether the PIC is supposed to generate the mouse
clock or whether the mouse does though... if the former then you'd
presumably see something on the clock line if the PIC was running.
Looking at the schematic, how the heck do PICs reset at power-on?
Presumably it's internal - I'm suprised reset isn't under user control
on one of the pins though...
cheers
