Small amounts (around 10 chips) are available at some manufactureres for prices of ~5..10k$ per batch.
Here http://www.nedopc.org/forum/viewtopic.php?f=79&t=218 is the report of an enthusiast who successfully manufactured his own trinary logic chips in such a way on 0.5um CMOS process.
I guess that NMOS-style schemes are still available in any CMOS ...

Similar processes/equipment will likely still exist for SSI and especially analog ICs - you could not shrink either of these indefinitely without messing with their robustness/current handling capacity, and analog parts would suffer terrible noise, precision, and drift issues in addition....

It should be feasible to manufacture NMOS-process parts using 0.6µm equipment that is still in current use. WDC's W65C02S, as well as their other current products, are made at TSMC on 0.6µm, though they are CMOS chips.
You would need to obtain examples of the original masks, have them converted to a format usable by the newer equipment (probably whole-...
