I just found a Metric Buttload of MC4024's (1978/1979 date codes). Mostly
MC4024P plastic DIP packages, a few MC4024L ceramic DIP packages. Found
the datasheet on Jim Thompson's website, stuck
one on a breadboard, hooked up a scope, and watched it do its stuff as
I tweaked Vin. Other than that, doesn't seem too awfully exciting.
(No offense, Jim, just that it's hard for me to get excited over a
15MHz VCO without a built-in phase detector).
I think I got these some years ago to use as VCO's in PLL data separators
for disk data (5MHz MFM, or maybe even 250/500kHz 8" floppy stuff). Probably
with tapped ring counters to do the "counting" and decoding.
Anyone interested in a few or a bunch of 'em for free? If so, drop me an
E-mail with "MC4024" in the subject and requested quantity and
your name and shipping address. I reserve the right to prioritize
sending them out, after all I'm paying for postage... US recipients will
probably come first just because of less paperwork/postage hassle.
