I've got my OSI C2-4P into a basically working state, to the point where the boot code
seeks to track 0 and tries to load the OS boot code.? I know I had a couple of plastic
disk-boxes with my OSI boot disks and some software, but I cannot find it anywhere.? I do
have some C1 Boot disks, but these won't work with a C2.? If anyone with a working
OS65D boot disk (and hopefully the tutorial disks) for a C2/4/8 would be willing to make
some copies for me, I'd be most grateful.
I believe it's possible to reconstruct a boot disk over a serial port, but I'd
rather keep that as a last resort.? That would be an exercise much like building a ship in
a bottle.
Thanks,
Dave

I'll second this -- I have exactly the same machine, with exactly the
same problem -- no bootable media. I was actually preparing to send out
a similar mail in the next few weeks; you beat me to it :).

I and some other people modified the OS in high school to make it
better to use. I haven't figured out which is the best version from
the disks I have. If you don't get someone with normal disks email me and I
can make you copies of one of mine. The modifications were for the video
board version so if you have a serial machine I will have to see if they are
useable.

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
