I recently bought (used) the Easy87 8087 coprocessor board. In the in-
structions, they said I should put the system in the monitor mode, and
at the "familiar" hand prompt, depress the "S" key. The instructions
said if I had installed the 8087 properly, then "8087" would appear
in response to the "S" command at the hand prompt.
However, "8087" does not appear. However, I know for a fact the Z-100
is making use of the 8087 ith appropriate software). I use the
Microsoft QuickC 2.0 for development simulation work, and when it is
compiled in a default manner, it tests for the 8087 and uses it if present.
Thus programs that previously took 100 secs. run in 5 secs, so I know
that QuickC 2.0 finds the 8087.
I guess my question is: Are the Easy87 instructions wrong in saying the
"8087" should appear in response to the "S" command? Or, is there some-
thing (like a jumper, whatever, etc.) I should have set when I installed
the coprocessor? I guess I'm just curious more than anything else since
the only application I have that can use the 8087 is the QuickC.

There are no jumpers or other hokey, I(nferior) B(ut) M(arketable)-like dipswitches etc to set. If you have access to them (or know someone who does) the short-lived Borland magazines contained an excellent article describing how Borland language products determine presence of an 8087. Similar should hold for others. QuickC runs on the Z-100??? Tell me more; I'd like to know more!! Walt K.
