Hopefully the PIC tag is appropriate; that's part of my question.

I bought the LED Light Show from All Electronics.  It's quite nice, but
cycles automatically through its different effects, I was hoping it was
selectable.  I decided to open the control box and see if I could replace it
with my own.

It's controlled by a chip with the Microchip logo and the part number
"CF745-04/P".  A search on the Microchip website turned up no matches and
when I search google, I get a lot of pages that I don't have a character set
for but seem to have this part number and 16C54 together.  Is it comparable
to a PIC16C54?  It also says "9736 CAW".  The 9736 sounds like a date code.

I haven't drawn a schematic, but there's 8 driver circuits with a diode,
resistor and a to-92 package with the marking "h sd 005 he r" on them.  It's
probably a house numbered transistor, but if anyone has a better idea, it
would be helpful.

Each driver circuit has a line out to the wire that goes to the LED chains,
but there's only the 8 wires, no ground, so I can't tell how that works.

Thanks,

Jason
