[sdiy] 93-series TTL logic

[Karl Ekdahl]

So...  i apparently got a bunch. dated to early 70's.
Anyone got any info on them? They don't seem *too*
useful, information on the internet is scarce. They
don't appear to have the same functions as 74xxx where
xxx should be the function so i don't have a clue of
what they do. Should i just toss them maybe? I do have
a bunch of 74xxx that i'm not scraping just because
i'm going to...   ..ahem...   ..build the worlds
largest "pocket" calculator??

yepp
