Sure - they're readily available from all the
usual electronics
suppliers. For example, Jameco stocks the following:
51908 80387-16SX IC,80387-16SX
51924 80387-20SX IC,80387-20SX
51941 80387-33 IC,80387-33
76531 80387-25SX IC,80387-25SX 68PLCC
76582 80387-40 IC,80387-40
Thanks... they're overpriecd than what they're really worth.
You have to keep in mind that Jameco's prices are in-line with
what they paid for them when they were still "current" items.
Considering that a 486DX2, including motherboard, can be purchased
for less than US$60 these days, yes these coprocessors are overpriced.
Similarly, DECdirect (1-800-DIGITAL) will gladly sell you a
KDF11-B (PDP-11/23 CPU) for US$1226, or a new RL02 10 Mbyte
disk pack for US$220. I'm not claiming that either of these are
great bargains, either, but they *are* useful resources.

That's perfectly fine for very few who REALLY NEEDS this kind of
resource to keep oddball machines going, it does happens from time to
time.
