So true. I happen to have one (from when I worked for Jim Ebright). It's the only mid-sized VAX I have plugged in at the moment. > I have chip pictures (http://simh.trailing-edge.com/semi/v11.html), Nice.

I remember having to update one of my two T1001 boards so I could run them together as a VAX8300 (our box was purchased with a single CPU, then I picked up a second CPU board for ~$100 with some random microcode rev, and got it all working as our first SMP machine). This reminds me I should probably archive my console RX50 media. Nice little machine. For us, it was a nice bump up from our 11/750, but by the time it came along, it was mostly a development machine, so it was pretty much a single-user workstation for me. Our 11/750 was still the general office machine with our productivity apps, e-mail, etc. The 8200 was capable of so much more but its big accomplishment for us was allowing us to make our VAXBI COMBOARD, and for _only_ $13,000! -ethan _______________________________________________ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
