It seems we only need a few more parts available to be able to simulate Ben Eater's SAP-1 based 8-bit computer.Notably, these are missing from the catalog:
74HC161 4-bit binary counter
74HC245 8-bit bus transceiver
74HC595 8-bit shift register
Would be great if these parts in particular could be added! Curious about plans to expand the availability of 74HCxxx components in the catalog in general as well, but I think those are the ones that beginners wanting to use CRUMB to learn logic basics would benefit most from right now.
