[sdiy] DIY IC's at Home

[David Ingebretsen]

The closest I've seen is what George Hearn is doing with SMT components. He
has come up with a replacement for an SSM204 filter chip that is pretty
compact and is a pin for pin replacement (albeit with an adapter...) He has
a couple of other potted "chips" which he sells on his web site and EG and
VCO. I bought a couple of the EG chips and some 2040 clones to play with.

They're about 22.4 mm on a side. Not teeny, but small.

~~ This is interesting.

~~ FPGAs, Curtis chips and so on. It struck me that with todays printer

'70s
~~ and '80s, I would think it would be comparable and more than good enough
