That's may be big enough without volume switching, but in any case, if it speaks MSCP, RSTS will support it. (Well -- more precisely, if it speaks MSCP and have fewer than 2^23 blocks.) >> ... >> You mean build an initial system on a small disk, and then load the rest >> onto a big disk some other way?

Yes, that will be fine. If the disk is RL02-ish in size it will be ample for this purpose. Even something as small as an RK05 can probably be made to do a basic job. paul
