Hi Marty,
I have one of the double-density models and can provide you with
copies of docs and some software. I have a bunch of application
software but it's in quad-density format for the Advantage and I
haven't bothered to transfer any of it to the Horizon.
The Horizon is a terrific, solid machine. The first serial port
is for the console and the second port is available for a printer,
etc. Both are easily reconfigured via the USER.ASM code (at least
my Lifeboat CP/M version). Two parallel ports are also available
on the motherboard.
I'm not sure if the Horizon bus is fully IEEE-696 compliant. Tim or
Allison?
BTW, California Digital (
www.cadigital.com) sells hard-sectored
disks for around $10/box. They also have 8" SSDD floppies (ran
out of double-sided, unfortunately).
