Yes, I did my homework and searched the message archives and I found
no specific references to these questions, so here goes:
1.- I am now building a MOTM-420 which uses the SSM2220. Is this part
or any MOTM part rare enough that I should be buying spares?
2.- I have not been putting any of the gerden-variety ICs in sockets,
just soldering them into the PCB. I mean a 555 is worth what, $0.50?
But what about the comparatively exotic SSM chips?
Am I unduly concerned?
