Very few 11/23 systems actually exist. Most people really have 11/23+ systems, even if they are not aware of it. It's a dual-height board. I don't think it /can/ be an 11/23+! Doh! So you actually have a KDF11-AA (M8186). That sucks. I'm not sure if those were ever upgraded to 22-bit addressing, or if you need the KDF11-BA (M8189) for that. Oh well, so you might actually be stuck with 11M then. (That said, without split I/D-space, you'll have preciously little pool space, but that might not be a big issue for you right here.) Probably not. I'll only have one disk in use at a time really. Pool space is used for many things, but with just one user, and few things running, not much pool is needed. Ahh. I must be thinking of...buffer space? Not sure what you are thinking of. :-) I'm tired and I've been fiddling with many different things. ;) :-) Johnny
