Well, while we are on the subject, there is yet another Z-80 machine around.
Namely, the MAX-80 by Lobo. I'm not a big fan, but if you have to have a
Z-80 machine, this one is worth checking out. It runs CP/M or LDOS.
Outputs are, 5-inch floppy, 8-inch floppy, SASI harddisk, Centronics
parallel, 2 RS232 ports (Zilog PIO chip),  and composite video. The
RS232 ports can be set up to generate interupts, so it can run serial
I/O at 19K baud. It has a real keyboard, with ALL the keys and a good
feel, for those touch typist. I have a 3.25 inch floppy drive on one of them
that holds 750K and the drive only cost $175. The MAX is fairly cheap to
expand since the controllers are smart. It doesn't have high-res graphics.
It does have programable fonts. For more information, you can contact
Lobo Systems, 7334 Hollister Ave., Suite J, Coleta, CA 93117.
Phone 805-968-6929. I have a couple of their machines and they run fine.
Warranty service has been quick and when they fix a machine, it stays fixed.
Usual disclaimers go here.
