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....
