FYI: Mine was built in September, 1985, so I would imagine they would need
some time to ramp up production for the introduction.

Not bootable, 'cause it boots from ROM. BTW, SSDD 80 Track, 9SPT.

I'm at work, 600 at home (awaiting new internal nicads...) but unless Tandy
or Zenith (OEM) designed a floppy-port-based whatever, the external floppy
port is a 1-for-1 pinout of a standard floppy interface... so you can hook
up either a 3.5" or 5.25" floppy, provided it's 80 tracks or more. (That
means I could hook up my 2" floppy, if I designed an interface cable, as it
only has a 22-pin cable (all standard signals, plus power... just need to
align the signals.)

AC adapter is 8V DC, 1.5A, IIRC. (hafta look when I get home...)

It's called HH/OS, (Hand-Held Operating System... tho I doubt you'd call
the 600 a hand-held!) and it was produced by MicroSoft.

Didn't the Basic ROM originally cost $139.95, or did it go up from
original? (I'll have to look that one up in my '89 catalog...) Tandy still
sells the ROM, and they still want $120 for it!!!!! :-(
