- I worked on a back-port of GW-BASIC (the unIBM version of BASICA) to the
- Z-80. Running on a 3.58Mhz Z-80, with token compatibility (in other words,
- a BASICA program "SAVEd" to floppy and loaded on the Z-80), the games that
- IBM shipped with DOS 1.x ran about 3 times as fast on the Z-80.

- Of course, the "standard" that these guys were trying to produce never
- went anywhere in the US, although it was big in the Far East. Hint: The name
- of the standard is also the name of a disease that affects cattle. Any
- guesses? 8-}

- I was working at another shop when Microsoft got the rights to Xenix from
- WECo. We actually had a PDP-11/34 running "Xenix". Of course, all the manuals
- were photocopies with the WECo logo and name markered out and "Microsoft"
- written on the cover. We kept nagging them, saying "but when are you going to
- _do_ something with this operating system?". They pretty much ignored it for
- a _very_ long time.
