HP-71B & PILBox & Remote Terminal

Hi, just wondering if you/anyone worked out which HP 75 LEX has KEYBOARD IS in it as I haven't found it yet?

Thanks, dmh

I have not tried it, but it appears to be a likely candidate. No idea if this includes the KEYBOARD IS keyword, but 512 bytes appears large enough to include more than a single Fn.

The HELP LEX file (about 2/3 the way down the article) is the go-to tool to see which keywords are in a given LEX file, described in this helpful thread:

https://www.hpmuseum.org/cgi-sys/cgiwrap...read=76286

The HELP LEX file can be found in the OLDP SWAP/HPCC88 volume.

While searching for and verifying LEX files, etc. it is quite handy to use JFG's emu75/DOS (run on DOSBox) together with ILPer (via ILPilBox virtual connector). It takes a fair amount of fiddling to get it all setup initially, but once working, it's dead reliable and involves a lot less thrashing.

Since posting that, I was told there is no KEYBOARD IS available for the HP-75 as the HP-IL support built-in does not provide the needed, apparently low-level, features to implement that. I am not 100% sure this is the case, but it is consistent with the 71B coming later and having the most powerful HP-IL implementation among the calculator models, and that no one has reported finding it.

But I would love to be wrong about this....

There is no known stand-alone KEYBOARD LEX for the HP-75, but the KEYBOARD IS statement is present in the I/O ROM.

As I was checking, I noticed that it's no more possible to browse Joe's OnLine Disk Project collection on hhuc.us/2014.
Individual files can be accessed for instance: HELPDOC75.txt
but not the root folder or any sub-folders: hhuc.us/2014/files/Speakers/08,09%20Joseph%20Horn/Online%20LIF%20Disk%20Project

The collection can still be found on Joe's site: https://holyjoe.net/HP71/Online-LIF-Disk-Project.zip
but it was very convenient to be able to browse it on-line.

Excellent news, I was wrong. And only yesterday I believe I told Sylvain that this is not in the I/O ROM... <sigh>

The HHC website was recently moved to a new server, and this is apparently a side-effect of that move. I'll look into it with the folks involved and see if it can be easily restored.

[dmh]

Thanks. So I assume this means I need a physical ROM to run on a real 75?

Is there a LEX version of the I/O ROM so I can load into memory?

If not, would it be feasible to create one from the source (for just KEYBOARD IS, say)?

Yep!

The source code of the I/O ROM is available on HP-75 groups.io forum
Under: Hp75/Files/75 Application (plug-in) ROMs and DEVICES/00075-15001 IO ROM/...

Oh, ok. I read that as there is no LEX file JUST containing KEYBOARD IS so wondered if there was something else/similar with it and other things.

I'll have a look at the source code and the assembler :-)

Thanks!

There is no such LEX in the OLDP collection, and I didn't find anything in the comprehensive LEX keyword list made by Paul Berger, available on groups.io/g/hp75 .
If you have some interest in the HP-75, I can advise to join the group. The last 75 experts are there (we are not so many).

Creating a KEYBOARD LEX has already been considered (here), but be aware that converting a ROM-based LEX to RAM requires some work (and knowledge).

[dmh]

Thank you for clarifying.

I did wonder about the conversion process so thanks for that too. If you have any other pointers or tips they would be appreciated (I'm looking at the NOMAS LEX section).

I'll look at some examples first and go from there.
