[Coco] 3.5" Floppies on my Coco 3!

[Bill Pierce]

Kip,
On the Vcc 4gig disk, just overclock the cpu (Configuration/config/cpu) to the max and overclock the disk drive (Cartridge/FD-502 Config/check "Overclock disk drive") and it'll take about 2 mins or less based on the speed of your PC and PC hd.

I format a 125meg disk in about 10 sec that way.

Hi All,

I communicated with my very first two 3.5" floppy drives on my Coco 3 using
Disto's Super Controller tonight!  I put HDBDOS 1.4 DW4 in the super
controller.  It also has the 80x24 Composite video output daughter board
with the mono sound output, an RTC and a Centronics Parallel port all on the
daughter board for those that don't know what a Disto Super Controller is.

I successfully formatted two real 720KB 3.5" disks and one 1.44MB disk with
the capacity hole covered to make it look like a 720KB disk.

I then wrote a little basic program and saved it onto one of each type of
disk.  I erased it from memory and read it back into the computer, ran the
program and it worked great!

I now have a minimal disk based Coco 3 128KB RAM 6809 based computer system
running for real!  On with the upgrades!  Hummmmm.  What to do first?

Now I need to get it connected to Drivewire 4 server and have the world at
my fingertips, then the fun will really begin.

Oh yea, I'm experimenting with a 4GB disk image file in VCC.  I wonder how
many days that will take to format!  I thought I might like to find out!  J
I dmoded /x3 with 65535 cylinders, 14 sides, and 18 sectors per track.  

The last time I had a disk based Coco 3 was no later than during the early
to middle of the 1980's.  I'm having lots of fun!  How about you?

Kip
