Hi David,

I would be grateful for a modified boot disk, as long as it boots.  All my working OS \
disks were also heavily modified as well, although I did keep a write-protected \
canonical OS65D 3.2 disk.  Do you remember what modifications you had made?


I know I have the whole set of disks somewhere, but I just cannot find them.  If you \
are willing to mail me a disk, I would be happy to compensate you for media and \
postage.   I plan to attend the VCF East this May, so perhaps I can buy you a beer as \
well.  I'd love to meet up and compare notes, and shoot the breeze.


One thing I'd like to do is write a little utility to bootstrap an OSI disk system to \
create bootable disks over the serial port.  Ed wrote a couple of routines to extract \
entire disks (raw) or all but track 0 (formatted.)  However, it seems I will have to \
fill in a way to re-create the disk from the images.  When you sent me the Beta/65 \
images, did you use Ed's utility, or was it one of your own?

Come to think of it, it would be really nice if you are able to send an image of a \
bootable disk as well, so I could compare it with the bootable physical disk, and \
(with your permission) also post it on the web site, along with my C1 disk images, \
and any others I can gather.  I think one of the biggest challenges for OSI owners \
nowadays is getting a bootable system, and finding usable software.  I recently had \
PCB's made to replace the A13 paddle-boards with a little extra circuitry for motor \
control and data-separator, and some extra jumpers to allow 


Thanks again for your offer!  Best regards,

Dave
