[SunRescue] Using HP 2247 and HP 2490A drives in Sun3?

[BSD Bob]

In the constant effort to get the last gasp out of my sun3 and sun4 toyz,
I picked up a box of HP 2247 and 2490A drives and a nice 4 bay drive
cabinet with apparently good cabling inside, today, in surplus.  The
2247's are 1 gig, but I am not sure of the 2490A's yet.  Anyone know of
any problems or gotchas in running these HP drives on sun3 or sun4 vme
crates?  Things like jumper settings, etc., are probably my main gotcha.
I am assuming motor on and no parity is required?  Anything else?

Thanks

Bob
