I just don't know the answers. I noticed that Pdp11's come in 2 types - qbus and unibus. Do the numbers of the machines like pdp-11/23 and pdp-11/24 relate to which is which type? And can someone tell me the differences between qbus-ing and unibuses, as to which is possibly better or what drawbacks they might hold. -Tom Hinds rocker@bucsf.bu.edu
