[Coco] File transfers over DriveWire between PC and Coco hard disk

[Robert Gault]

There have been some claims that you need a floppy drive on the Coco to 
transfer files between a DriveWire mounted image on a PC and a Coco hard 
drive. That is not correct.

It is easy to set up a RAM disk on a Coco for use with HDBDOS. Drives 2 
and 3 become full RAM disk with a 512K Coco, rather than floppy or hard 
drive "disks" under Basic.
The content of these drives is stable even after a hard reset with 
ALT+CTRL+REST.

I have tested the RAM disk code that works with the KEN-TON scsi RGBDOS 
on a DriveWire HDBDOS system and the RAM disk still works. That means 
you can have your normal HDBDOS in ROM, load the RAM disk, load HDBDOS 
DW3, copy files from the PC to the RAM disk, reboot the Coco, start up 
the RAM disk, and the contents are still available for transfer to your 
Coco hard drive.

It is much easier running NitrOS-9 as no RAM disk is needed.
