CoCo Info Needed...

Otay, here's the situation, and I need some help, folks...

I've got a "new" project in mind, that I need to use my old computers for,
specifically CoCo's. I need to build at least a few temperature
controllers, and I wanted to use the internal ADC in one of my CoCo's, but
I'm not sure if they're high enough resolution... (6-bit) - until I
remembered the Hi-Res Joystick Adapter for the CoCo3 that plugs into both
the joystick port & the cassette port.

Now, does anyone have any info on the hardware & programming of that port?
I remember that the gizmo mimiced the resolution of the CoCo3, as in 640
(methinks it was around 10bit, wasn't it) distinct steps, and I think it
used the DAC of the cassette port in conjunction with the ADC of the
joystick port, but I have no idears about how to program the rascal, or how
to replicate it (I could use *at least* 2, and I only own one myself)...

I've searched some of my Rainbow's to no avail (methinks Hot CoCo was
already bought out by then...) but my collection stops around December of
'86, and I thought in '87 there was an article or two on just how that
thingy worked.

Any info at all would be most appreciated, and thank you very much in
advance for any help y'all can provide.

Oh, BTW, if you do reply privately, my zmerch_at_30below.com address is
presently being flooded by double-bounces (I'm a sysadmin at a small ISP)
from that %^(*$&#^_at_(%) Snowhite (W32-Hybris) Virus, so if you do reply
privately, use zmerch7_at_yahoo.com or ab8kk_at_eudoramail.com.

Thanks Much,
