I found on github a guy who build a little board with an FPGA emulating 40010 functions.

https://github.com/codedchip/AMSGateArray

Unfortunately there are no kidad (or other) schema for order it on JLCPCB (soldering a SMD chip is too complex to me), nay of you know something about this GA replacement?

thx

Yes. It is the gerald's schematic design that was expected to fit into a XC95288 CPLD.
His original project is more ambitious, by fitting into the socket only! :)

OMG that's perfect!!
Who sell this little masterpieces? (or upload on github the project).

I'm trying to resuscitate a CPC6128 from death, already ordered CPU, FDD controller and 46505, ask a friend to "burn" a couple of 27c but 40010 is almost impossible to find.

thanks

It is the gerald's prototype. Waiting for it... :)

@Alessio There are gerber board files here https://github.com/codedchip/AMSGateArray/tree/master/40010 . just upload the gerbers.zip file to jlcpcb. If you are not able to solder the CPLD maybe there is a repair shop local to you that might be able to help? 

I ordered a set of both the 40007 and 40010. My old 464 uses the 40007 and it doesn't quite work with my system for some unknown reason(see my result here: https://www.cpcwiki.eu/forum/amstrad-cpc-hardware/gate-array-decapped!/msg217953/#msg217953 ), but many are reporting success with the 40010.  
If anything's gonna happen, it's gonna happen out there.
