Yes, it's a ROM for the 41. It's a very good ROM and usefull even if
you don't have any HP-IL stuff.
Yes, exactly. It shows the description of all the parts in the kit and
has the schematics of the 82166 convertor. It has more but I can't find my
copy at the moment.
Tony mentioned
HP-IL and that made me think of what I've been plodding
through today: a box full of HP-41 and HP-IL documentation. Shame I
Well done!. Some of those manuals are not common
So what have I got? Well, thus far:
The HP-IL Interface Specification
p/n 82166-90017, Nov 1982
IIRC that's the low-level spec of the HPIL and it gives things like the
electrical description of 0's and 1's, the frame formats, etc.
HP 00041-15043 HP-IL Development Module
Owner's Manual
p/n 00041-90449 Rev B, Oct 1984
A ROM for the HP41, I think. Essential if you use HPIL on the 41, but
I've only really used it on the 71B and the HP150-II. 1LB3-0003 The HP-IL Integrated Circuit User's
Manual
p/n 82166-90016 Rev B, Nov 1983
The 1LB3 is a custom HP chip that sits on an 8 bit microprocessor bus and
talks HPIL on the other side. Most HP HPIL units, apart from the handheld
calculators, contain this chip. That book is essentially the data sheet
for it
HP 82166C The HP-IL Interface Kit Technical
Guide
p/n 82166-90020 Rev B, May 1983
Dunno that one. Possibly the manual for the kit that contained 1LB3s and
some programmed 3870 microcontrollers?

The operating manual for the 82166.

Converter Manual Supplement
> p/n 82165-90012, Oct 1982
The operating manual for the 82165. The 82165 is similar to the 82166 (
IL to 16 bit parallel buss) but the 82165 is bigger and runs from a HP
82159 wall wart that provides 8 VAC power. The 82166 requires 5 VDC.
The 82166 was an interface between some 8-bit ports and the HPIL, with
the controller on the HPIL side. It's a fun device for linking up
homebrew projects to calculators. There was also a version called the
82165, which was in the standard case (like the HPIB converter and the
RS232 converter), and had a DB25-S connector for the 'GPIO' parallel port.
Yeap, except they have 16 I/O lines and a couple of handshaking lines.
The 16 I/O lines can be software configured as input only, output only or
input & output. They can be software configured as one 16 bit port, two
8-bit ports, etc.

OK, that is what I found in the first binder. Somehow I have a feeling
I'm gonna wish I had Tony's clues by the time I get done with this.
Oh come on. I'm not that clueful, surely...
