I second this. It is a mod I'm interested in doing.

I am also looking to add realtime clock to my Kaypro 10 (83 version
board)

Same here. Though a copy of that portion of the bios that drives it
would also help to reverse engineer a logical equivilent.

I agree with Allison 100%. Having the code would be a big help. I've
reverse engineered the the K10 ROM and now I'm going to tackle the
TurboROM.

I have TurboRom eprom installed and I understand that it supports
realtime clock. This should solve the BIOS support issue.

My approach is to copy portion of 84 version of Kaypro 10 schematic,
which relates to realtime clock, and build a small daughter board.

I have extra PIO chip and the MM58167 real time clock chip.

Now I just need the spare time :-)

ISTR a little daughterboard based RTC for Z80 machines which plugged
into the CPU socket (you would move the CPU to a new socket on the
board). I think it's still installed in my K10, but I remember using it
with a PCPI Applicard as well. Should be simple to duplicate if I can
dig my way into where the old Kaypro is buried, err stored.

If you want to duplicate that, you can just build a GIDE interface card.
It includes an RTC and installs the same way.

If would be really handy to have a photo of top & bottom of board.

Thanks,

One was called Kenmore. I've got the manual around here somewhere ...

PLU*Perfect did handyman which was a Z80 piggy back that allow for the
handyman rom, clock and host interface (for hard disk or ramdisk).

Thanks! That was the very one.
