I too picked up a 610 replica and a pair of data separators from Grant and am going to use them to add a floppy drive interface (and optionally, RAM) to my recently acquired C1P. The second separator will be used to add a different floppy drive to my C1PMF, hopefully restoring it to full functionality. (but that is another thread).
I am not currently planning to populate the RAM portion of the board, instead opting to employ some sort of RAM/ROM board.
Here is my progress so far:

Re: Building the KLyball 610
Here is my parts list, complete with links where to buy components.
This one is courtesy OSI. UPDATE: revised color PCB layout file; added RAM chips and jumpers

Here are two handy chip placement guides.

Re: Building the KLyball 610
Here is info on setting the jumpers for Single or Dual sided floppies:
Also, R7 is 1K ohms.

Im not sure about X5-X14. Can anyone in the know verify this jumper for double-sided?Also, R7 is 1K ohms.

Re: Building the KLyball 610
Today I finished off the board (except for the floppy disk separator board) and tested it with 4K of RAM. I plugged it in and it fired up beautifully!

Here is what I was greeted with when I turned it on:
Now I have to build the separator and acquire a floppy. I have purchased this drive from eBay, but it hasn't arrived yet. It should arrive next week.
Hopefully I will be able to get it going!/Jeff

Re: Building the KLyball 610
Great progress Jeff! This is so cool!
The parts for my 600 board are slowly coming in. I should just have spent the money and gotten everything form Digikey, but I've tried to keep the cost down (fixed income and all ) and ordered a few things from the far east (like the Cherry key switches).

Re: Building the KLyball 610
Looking good.
I think R20 could be a miss print, as I needed to change it to 1k to get the timing signal correct.

Re: Building the KLyball 610
Can anyone with an actual OSI 610 confirm the value of R20?

Re: Building the KLyball 610
Today I made the electrical adjustments on the 610 so support reading and writing to the floppy drive. I figured I would post the procedure so that the information is central for future builders.
R18 TX Clock
Remove floppy-disk cable (J3).
Input of scope to pin 13 of U68.
Adjust R18 for a positive pulse width of 400nSec +- 50nSec. R9 TX Data
Remove floppy-disk cable (J3).
Input of scope to pin 12 of U68.
Adjust R9 for a negative pulse width of 400nSec +- 50nSec.
continued in next post...
