If your system has a Z80 CPU, you may want to try a Kenmore Z-Time clock.
It's a piggyback board which plugs into the CPU socket of your machine
and then you plug your CPU chip into the clock board. It looks very
easy to "talk to", although I'm still having a tough time trying to
cram one into my Altos 580. (The motherboard is below the hard disk
and controller, and there's very little clearance. Then, of course, the
40-pin DIP headers I bought to build an extender cable hang too far over
the edges of the socket, and interfere with other chips...)

I don't have their address handy, but the Z-Time clock is made by an
outfit in Rochester, NY. It shouldn't be too tough to find one.
