I have a Kaypro II whos previous owner swapped the two full-height drives
for a pair of half-height units and made the resulting space into a
cubbyhole for disks and other things. Last time I had a good look at it,
I thought the drives were double-sided. Was it possible to get
double-sided drives to work with the Kaypro II?

A: Because it fouls the order in which people normally read text.
Q: Why is top-posting such a bad thing?

I have received DSDD disks that were explicitly stated to have been from a
II. When was the official switch to DS? Do the earlier machines need
more than a ROM upgrade? (is side-select present?)

Another thing, does anyone know where I can get a replacement bail to prop
up the machine instead of resting it on the keyboard?

Imagedisk should work. Dave has Kaypro II system disks on his site.

Once you have the data to go on them, you can write bootable disks for
kaypro on PC hardware.
Note: the Double sided Kaypro disks have an invalid value in the head
number field in the sector headers of the second side. But, it doesn't
CARE if you feed it a disk with the correct value there. So, to write
those disks, you do NOT need to talk to the FDC, you can create usable
disks with INT13h. Since they are 512 Bytes per sector, with 10 of them
per track), you will need to mess with Int1Eh for formatting the "pseudo"
Kaypro disks with the valid sector headers, after which Int 13h will be
adequate for reading and writing them.
If you talk to the FDC, instead of through Int13h and iEh, then you CAN
produce disks that even have the invalid sector headers.

I would check with Bud Industries and Hammond Manufacturing. If they don't
have anything you may have to have one made.
