I'll check out my reseller manual when I get into work this morning. The used market has these machines for the $1-4k range > 3B5 - Old small Big format mini.

All of these are discontinued (well, I guess I've not *personally* seen the termination papers on the 4000, but since it is literally built on top of a 3B15 I assume must be). The 3B5 and -15 were discontinued in the summer of 1989, and it is only because we have an outstanding local AT&T data shop (Larry Duffy!) that our machine has had such an excellent service record. These big machines never really made it too well outside of AT&T and the Bell Operating Companies, and it is clear to me that the 80x86 on the low end and Pyramid on the high end will be the future (such as that is) with AT&T. Notice that "3B2" is conspicuously absent from mention. Note: "discontinued" means "can't order it anymore". > DISCLAIMER: I have been peddling these things for several years.
