SX20AC/SS aftermarket source
I've been keeping the Stache BASIC Stamp programmer alive for a handful of customers. It was originally built around the SX20AC/SS, but that is long out of production. There's hoarder's inventory out there, and I have quotations mostly from China that range from $16 to $78 (!!) per chip in quantities from 20 to 100. To keep it alive, I've started refactoring the circuit around an SX48, which Parallax still has at $0.78 each, but it is a pita to have to redo the pcb layout and to tweak the firmware. I thought I'd ask if any of you forumistas has or knows of a warm source for SX20s?
