Re: Home-made SSI chips

That should be fun :-)
Reinventing the transistor :-)

One another scale I, sometime build some kindof chip myself, I'm not a 
pro, but I find useful to build some stuff into block.
Per exemple, a simple RC circuit build on a IC socket so it can be use 
on different kind of prototype board ...
;o)
