I have a couple of printsets for 11/750 at home think they are OK, may 
have
11/780 and 11/730 and possibly 8600 (on microfilm) too.

I think the 11/750 is the way to go, we have discussed making a fast 
scale-model
of the 11/750 and a SA-482 (with 2,5" IDE drives) for a couple of years 
at
a computerclub here in sweden (http://www.sdf.nu). The 11/750 ASICs are 
really
simple and included in the prints (the most complicated holds 28 gates).
