Internal Mac Floppy Drive on IIGS - cable pinout ?

[cd@pobox.com (Carlos Duarte Chester)]

Hello.

I am from Brazil, and was a *big* Apple II fanatic back in the old
days. Here in Brazil there were no IIGS or IIGS clones, so I decided
to have one nowadays. However, it is expensive to ship to Brazil, so I
bought a IIGS mainboard from eBay, and put the computer to work using
PC, II+/IIe and Mac parts (PC power supply and joystick, Mac keyboard
and so on). Some special cables/adapters were needed, but it works !
:-)

I have a 5.25 MicroSCI "A.5" drive, but, of course, I also need a 3.5
drive. I was able to obtain an internal Mac drive (MPF52A). The csa2
FAQ describes how to use it, but providing you already have an UniDisk
case, which I don't. So I'd need to build a cable to connect it to the
D-19 drive connector on the IIGS.

I was able to find the pinouts for both the IIGS connector and the
internal Mac floppy drive
(http://www.bme.unc.edu/~hope/linx/mac/pinouts.html#intflop and
several other places). However, I am not sure about how to build a
cable that would support boht my current 5.25 drive (a MicroSCI 5.25
with 19-pin plug but no daisy-chain connector) and this Mac drive.

As a worst-case scenario, I could find a Disk II interface clone to
plug one of the drives, but I would like to avoid that if possible
(not only I would need to find a Disk-II like drive, but there still
is the problem that I don't have the case (with the cable) - I cannot
find any info about the MicroSCI drive internals to see if I can use
its cable on the 3.5 drive.

Can anyone point me in some direction ?

Thank you very much for your attention.
