Hey I cant seem to find any CMOS 4006 at electronics stores. Some guy said that they dont make them anymore. Is there like a equivalent to them or a newer version.

I need them for a nintendo 64 controller to computer adaptor.

By googling I found a few places still selling those - although usually minimum orders of 10 pieces or more (but they are cheap to begin with).

You could also build an equivalent circuit out of 4-bit or 5-bit shift registers from the 74xx series, e.g. the 74HC95 or 74HC96.

Cmos 4006 for N64 to PC interface

Protolisk,

This does not seem to involve use of a PICAXE in any form. :(

Since the two 40056 IC’s are connected as nothing more than a 33 stage 1-bit shift register, why not be novel :eek:
and look at achieving the same result with a PICAXE :).
Data and Clock as signals into the PICAXE and one signal out.

EDIT:
okay seems I can answer the question myself . . .
Sending $01 to the controller makes it respond with 32 bits of button information.
Note that the controller responds VERY QUICKLY -- within 2 to 3us.
each bit has a duration of 4us (3us lo & 1us hi = 0 and 1us lo & 3us hi = 1).
so whatever you're using to talk to the N64 controller has to be very quick.
An 8MHz PIC would have a difficult time doing this. Better to use a 10-20MHz one and bit-bang it.

Yeah but picaxes are so much more expensive. Altronics raised their prices. I think I'll go to that one in clayton. How come all the electronic and computer stores are in clayton.
