28927Re: SCELBI PCBs on order
- Jan 11, 2013awesome,
I should have boards in about 2 weeks - still have to find many of the parts, but I think I have the hard ones (8008 and 1101) - most of the rest is pretty conventional 74xx series. The original units used a zener in a funky package for over voltage protection, witch I doubt can be found very easily, but there are modern equivalents. watch my blog as details unfold
Also I've promised Evan that MARCH will get a set of bare boards for free. It will be up to MARCH to find the parts and build it up into a museum piece.
