Bear in mind the memory is seriously rusty, and while I had quite a bit of experience with GCOS-8, I only used GCOS-6 for about two months total spread over 4 years. GCOS-8, and IIRC GCOS-6, is nothing like UNIX. On GCOS-8 the administrator accounts were simply accounts with extra permissions, I don't know that there was an actual "Super User" account. If there was anything that could be considered that it would be the "System Operators Console". Administrator accounts were cool as we could change our password to what WE wanted, not some random string (yeh, yeh, security and all that). No hardware tips, I never touched the things. I do remember the Tape drives for the DPS-6 being a problem, but that might have been the particular model we had. As for parts, I'd recommend checking Navy Surplus. Don't rememeber what it would be called, something like DRMO. The Navy used a LOT of Honeywell DPS-6 hardware, in fact the whole military used a lot of Honeywell hardware. Unfortunatly the odds are that all this hardware has been melted down for razor blades by now. On a simular note, if anyone knows were I can get one of the Honeywell/Macintosh hybrids that was build for the Military, I'd love one. They were based on the Mac II, and the one I used was based on a Mac IIfx. Zane | Zane H.
