actually, the 8087 had some features that the modern counterparts don't have
although - they lacked some of the nicer trig functions, etc

if you are serious about wanting an 8087-1 (10 MHz)

same guy - direct link

if i understand the page correctly, that is $40 US
that's a great price - i wouldn't sell the one i have for less than $250 because the -1 is very rare

i have read about guys using an 8087-2 (8 MHz) at 10 MHz
can't comment on success - lol

Yeah, best price I found even way back in the day was $250.  Very rare piece...

Currently only looking for free or cost of shipping only.  Wife's been out of work for 15 months now, and prospects don't look promising.  Can't get a job around here if you have any experience.  All they want are fresh out of college kids with no experience.  Not much spare money kicking around for things that aren't truly necessary.

i hear ya
similar situation here in the Phoenix area
they want newbies so they can pay bottom dollar

i figure the best avenue might be to start my own small company
it's "more patriotic" to create even 1 decent-paying job,
than it is to create 100 low-paying jobs, make millions of dollars, and stash it in a dubai account
