Re: MK14 schematic revisions
I think you have a point.. I just looked on eBay and there's someone selling NatSem DM74LS157 chips for cheap so I've ordered some of those, I don't mind having even more as they are a generally useful IC in many circuits and I'd rather not start pulling chips off of my vintage PCs if I can help it, especially since my desoldering iron committed self immolation last year and has yet to be replaced.
If I've any question I might take you up your offer Sirius!
