IIfx Memory

As I'm new to the IIfx, I'm trying to find memory for this computer as I only have a total of 8MB, what is the landscape like?
It looks like given the unique 64 pin 70/80ns DIMM requirements, that they are hard to find. No real listings that I can easily find.

Has any one made them? I did see a schematic on GitHub....

Or are there people out there with 4MB DIMMs willing to sell? Would love to get to 16 MB or 32 MB if able.

Thanks.

There's this: https://github.com/hanshuebner/maciifxsimm
I haven't tried it.

i made some of those, they work well.

Thanks @finkmac

I've been able to create the Gerber files from the GitHub site above. Priced out the creation of the PCBs on JLCPCB for around $7.00 for 15, and the stencil for around $16.00. The slow shipping is about $18... would need to source the chips -- can get the KM41C16000CK chips from UTSource for about 50 for $50 dollars.

I've just never used stencils before... just don't want to get too far down this.... however if memory is un-obtainable then this might be the best route.

Glad you were able to create them.... does this pricing seem right for your prior project? Did you use stencils?

just remember to choose the right thickness.

as the github project says, it's best to use a reflow oven type soldering process... that does indeed involve the stencil.
