Since you do have the iMacs now how about removing Telnet from the lab. The G3's should really be reserved for better use than having people using them for email which happens quite often. The instructor needn't be the one to remind students that there are computers for printing in the printer room. Possible solutions to reduce printing Num Percentage Duplex printing. Do you have any other comments about the computer classrooms.
Printing is a difficult problem.
I have had a very positive experience in the two years I have used the lab. I have never had to cancel a class or alter its contents due to technical problems. The new projector in 301A Surge IV is a very welcome addition. My problem sets mathematical reviews handouts etc are all available on the web and students tend to print them on campus printers. The natural solution would be to open accounts for students and charge per copy.
