The 03 is one of dem dere 16 bit devices, and can only address 32k words of memory. To run any flavor of *nix, you'll need a chunk o RAM - that means going to 22 bit, and forking over megabucks (at least for the common hobbiest). >And yes, people do still use them... I can say that, I have one. Me too! Running a nice drive subsystem I yanked out of an AED system (8" drive, acting like 2 RL02's) and a pseudo-non-dec-RX02. BTW - I'd love to beef my system to a 23 (it's a happy 18 bit bus), and fire up RSTS v9.4 under this (for development with my customers), but I'm having trouble addressing the RLV11 as the second controller. Can anyone tell me what the correct CSR and preferable vector is for this card? As I understand it, RSTS is very picky about where the floating vector is... +---------------------------------------------------------------+ | Dave Shevett ~---------------------~ Labyrinth II BBS | | W.
