It came with 64K memory - maximum the LSI-11 will address and either DECtape II or RX01 floppies. It is a bounded system: The internal bus is not accessible in any documented way; whatever you get, you keep. If I remember right, the floppy version came in a standalone box, which the DECtape version was built into a VT100 cabinet. A version of RT-11 was the only supported O/S. The machine is small by today's standards, is slow, and has very slow periphs. I have seen some nifty things done on it - mainly "very smart terminals" - and people have run DECUS C under RT-11 successfully - but it isn't easy (because of space/speed limitations). BTW, I'd make sure that the special RT-11 - special only in having special device drivers - came with the system; I doubt you can get it anywhere any more. (Unless, of course, you are willing to start out with ROM ODT and "roll your own" from scratch.) -- Jerry decvax!yale-comix!leichter leichter@yale
