It *should*. I know the LC3's PDS slot is an extended connector but I think
the signals are compatible on the common portion.

I don't recall if there is a socket, but if present I would guess it's PLCC.
In any case, I'd preferentially just get an accelerator board for it -- much
simpler affair. They show up on eBay all the time.
LowEndMac has a good page on the LC3, try

Same clock. However, there is a very easy way to overclock the entire machine
and effectively turn it into a LC3+ (warning: you'll need to make sure you
have the right System Enablers installed *before* you do this or the machine
will no longer boot). See
http://www.lowendmac.net/chip/lc.html
This will bring you up to 33MHz. However, if you go get the board, I would
wait on trying this modification as many of them do not like LC3+'s (and it
tanks the machine's Gestalt ID).
Speaking of clock chipping, if you have a Mac Plus why not extend it to 1GHz?
(Especially on one particular day of the year.) See

I'd say 300MB is plenty. You can probably get away with as little as 100MB
but I wouldn't push it.

Why not a IIci? Cache cards are cheap and fast, it does have an FPU, three
NuBus slots, 30-pin SIMMS are practically being given away, and compatible
with ruddy near everything? :-) Also, you can put more than 36MB in it.
Failing that, perhaps a Q700 ('040)?

Stop by the office and I'll see if you should be involuntarily committed. :-)
