Very nice applications - My congratulations!
BTW: The 2nd link is (somewhat) broken, there's a 'http//' too much.
OT, but just came into my mind:
On the Allschwil2006 meeting, I demonstrated a setup of an HP-41,
an HP-71B, and an HP-48 connected together at the same time.
The connection was made with a CMT Multicase, which includes
an HP-IL RAM disc, an HP-IL LC display, and a battery-powered
version of a 82164A compatible serial interface.
Actually the essential part was the 82164A interface,
the display was nice for the visual feedback,
and the RAM disc allowed for tempaorary data storage.
With the HP-71 in HP-IL device mode ('CONTROL OFF'),
one could control the HP-IL side with the HP-41,
and send and receive data from and to the HP-48,
which was connected to the serial port.
On the Allschwil meeting before, I also showed
a special HP-IL interface made especially for the HP-48.
With this interface and the associated control library on the HP-48,
it is possible to access HP-IL mass storage devices,
and, amongst other things, print to an HP-IL printer.
The interface, made by W&W, is different from the HP
made HP-IL-to-somewhere interfaces in the respect that
the W&W interface is configured as the loop controller.
This way the HP-48, with this interface, can be seen as an HP-IL controller.
Unfortunately I haven't found a way to turn off control
on the interface so far, and in consequence you can't connect an
HP-41 on the IL side, except if you set the HP-41 into MONITOR mode...
