David, very brave work you do. We should find a business case to be able to collect money on a crowd funding platform like kickstarter.com
So we *need* a product and a road map. The product needs to be catchy and address needs of a geek. So as I wrote today, I strongly suggest building C64 spares, beginning with the CIA-peripheral, as peripherals get broken most likely as they are exposed to experimentation, e.g. user port.
How to package, do we have access to a package molding company or package molding tools, in order to put our chips into a nice DIL40 package https://www.c64-wiki.com/wiki/CIA http://www.6502.org/documents/datasheets/mos/ We can by a C64 and do reverse engineering by grinding and photographing the layers of the chips if needed. http://www.degate.org/documentation/
Lets do DIL40 stuff first, as I think there is some quite easy money :-)
Cheers ludwig

Hello
Thing is that I have not seen any electrical measurements of any active device yet.
Yes. The first active devices should be functional mid of next week.
We had to figure out a proper way to form silicide and to interconnect the wires with the transistors. That was ground work and is basically done now. Resistor measurements will be done tomorrow...
And by measuring the transfer function of a transistor and storing it numerically into a file allows to create a SPICE model from it.
That's why I say, on Friday in a week we will most likely be able to provide the first models...
I think, the main reason why everyone is waiting for the project to run out of money or the people to walk away is rather, that established foundries, of which there are only a few, have not much interest into having another competitor. We had to research the things, the foundries keep a secret and worked the rest of the stuff out from scientific papers. Took a while, but because there is now a lot of literature, it's quicker than the first time around, when the first foundries had to figure it out from scratch.
