Does anyone here know where I can get a Mega // chip (with, hopefully, a pin-out) without having to cannibalize an Apple // GS motherboard? I’ve been contemplating a project for years, and still no easy solution.
The pinout is relatively easy: it’s in the circuit diagram.
I think the diagram was originally part of the hardware reference manual
(see also here)
But to get a chip, I think someone somewhere needs to take it out of a IIgs. Preferably a dead one! (Or else someone needs to make an FPGA recreation, which would be technically possible but probably rather difficult to get exactly right.)

Thanks for the manuals. It seems like either way won’t be easy.
Thanks for the link. I left a message, and hopefully they’ll be able to help me out.
Okay, so far, no luck. I’m wondering if the Apple // e card from the earlier versions of Mac could be used to make a laptop //e. It has the Mega // chip on it, and supposedly everything needed to emulate an Apple //e. Ideas?
I almost forgot - I ws hoping I could get it to fit in an eMate 300 shell. I’m hoping it will make a sturdier laptop, but I could see if I can make my own case.
Sounds possible!
I found a video by the 8 bit guy on Youtube about this card. It uses some of the Mac’s
hardware to work. It may be possible, but I’m not entirely sure it would fit in a eMate shell.
Perhaps this video:
Yep, that’s the one!
