I started with=20 those guy doing a contract job to craft the second nework interface into=20 Secure Xenix (Jacob Recter I think was responsible for the first) to=20 provide a secure downgrading system for some government entity. Then Intel developed the i860- and IBM came up with the Wizard card. =20 This was only designed to be.a coprocessor card and was done down in=20 Boca Raton. The fun and games with that one is that we were on early=20 steppings of the processor chips and spent a lot of time coding around=20 chip bugs (mostly with regard to interrupts). IBM/Intel had developed=20 this thing called hostlink that was supposed to be useful, but we=20 decided to port AIX to it. When IBM Owego came up with the W4, we were=20 asked to port AIX again to it. We had one non-functional W4 kicking around for demo purposes that had 4=20 =E2=80=9Cdelidded=E2=80=9D i860 chips in it. I swapped one for an early= stepping=20 (useless) chip and kept one of the delidded ones which I still have in a=20 box somewhere.
