Yes, 60 bits one's complement, oddball floating point format, 12 bit one's complement I/O processors...
Your memory is quite good. That's just how it works, in all the various OSs I know.
BTW, there exists an emulator -- DtCyber ("Desktop Cyber").

No such file or at end of file.
The user had to type the REWIND command. The compiler could then read the sourcefile again :-)

Apart from the DECnet requirement, if you want weird I don't think you can top a CDC 6000 series machine. The size can be a bit problematic, I suppose.
My dream (about 10% complete) is to build a replica in an FPGA. I have the schematics to do it, it's just a whole lot of work...

Technically AIX isn't just a "random unix box" it's weird with a POSIX layer on top. :-D
Definitely not as weird as an AS/400 though
Depends how you look at it. Some RS/6000 gear is weird hardware wise and AIX is certainly interesting as UNIX systems go (in the Chinese sense mostly). It's more sort if interspersed layers of IBM weirdness and UNIX compliance sorta knitted into a funky tank top ;)

It wasn't until 95 with Microsoft including TCP/IP into the consumer OS did it really start to matter.
Yes I do remember the days when Windows 3.11 had Winsock to provide a separate TCP stack. We used it and SLIP to dial up to our ISP back then. We had to keep a Windows 3.1 box on the modem for quite a while until we worked out how to build SLIP dialup scripts for Windows 95.
Sometimes I swear I was born 10 years too late :(
When I first started working at PSU our PC lab was a bunch of IBM PS/2 machines connected to Token Ring running DOS and the TCP/IP shim stuff. It was weird and a giant pain in the ass to say the least.
The Unix/DEC hardware was sooooooooooo much easier to manage. :-D

Not true, not unless the implementation is crummy. Any halfway decent fast Ethernet host will run at wire speed, and the difference between 1500 and 4460 MTU isn't enough to amount to very much.
Except for the fact that on ethernet you took the framing hit to your speed (100Mbps link level) and with FDDI the framing was done outside of your "speed" (125Mbps link level, true 100Mbps data).

Ah, so that's your specification for an interesting system: weird with DECnet :-)
The AS/400 is a nice choice then . 48 bit architecture, was supposed to replace the S/38 (it's code compatible with it) and be a VAX killer at the same time.
Which obviously didn't work since every home has a VAX now as Johnny tells us repeatedly (or did I get something wrong ;-)
Anyway, I've configured the IP stack on one of them, 10 years ago and what I remember is this.
It follows the IBM way of doing things : nearly everything is menu driven. A system manager hardly ever types commands, he just fills in forms. The result ends up in a file which gets compiled or assembled with a bunch of others. AIX has something similar called SMIT (if my memry serves me well).
Well, I prefer to type my own commands and DCL scripts.
I'd like to get a small Unisys (n e Burroughs) A4 though.

What do you mean by that?
Just that the discussions lately seems to have started assuming that everyone is running VMS. :-)
But I know that most people know that this is not true. I just felt like pointing it out. Not trying to offend anyone.
