Goodrich Matchbox 2B

[Dave Seddon]

Can anyone tell me witch IC is used in the Matchbox Model 2B. Thanks.

[Larry Dering]

Dave, is there no information on the IC chip itself? I know the components seem to be a trade secret and often they wiped the printing off the chips.

[Dave Seddon]

Larry thanks for your reply, the number on the chip has been wiped clean, I'm wondering if it's something as simple as a TL071 or TL072?

[Larry Dering]

Its possible. The Goodrich 7A uses a MC3481P Chip. I got several older Matchbox's but not your model. The older ones didn't use a chip. I don't think Keven at Goodrich has schematic for older stuff. You might try calling him and see.
