I still have a small 11/23 in a BDV11-VA shoebox with a pair of Tu58s, 
with 256k of ram it boots RT-11 in about a minute and longer (about 
10minutes) from there to copy it to VM: and reboot from there to save on 
running tape for small things.

If it took a luch time then the user never read teh chapter on using the 
TU58 and there is a note on how to optimize that.
