    I replied to Camiel off-list, but I just did want to say to the list in general how great it made me feel that my idle BSing got a thoughtful reply from someone who is in a—indeed, in *the*—position to know about it.  I mean, I realize I shouldn’t be surprised that VSI has a presence on here, but…I was!

Well, I’m not on cctech because I’m with VSI, I’m on cctech because I have a large collection of vintage computers (www.vaxbarn.com). In a sense, you could say that my being with VSI is an indirect result of being a computer collector. I had a few Alpha systems, wanted to develop software for them on my laptop, decided to write my own emulator (ES40 Emulator, also forked as AXPbox), got to know people in VMS engineering as a result, and eventually ended up getting hired as one of the principal architects for the x86-64 port.

I have a few OpenVMS related presentations up on Youtube, one of them is specifically about the 4-mode problem (https://youtu.be/U8kcfvJ1Iec). I also have several vintage computer related videos on there (Reviving 1980's supercomputers at home - https://youtu.be/0uM09vxT1rg - is a nice introduction into the kind of things I'm really interested in.)
