Re: Math "ROM" in "RAM"? What about in EMU71 ROM? Message #20 Posted by Chris B. on 29 Nov 2005, 1:56 p.m., in response to message #19 by J-F Garnier
Hi J-F,
This thread has got me thinking about something I've been confused about regarding EMU71 (which by the way is a *fantastic* tool that I plan to upgrade to full HPIL functionality). Is the MathROM actually included with (or is the ROM .BIN file available to load into) EMU71? I've read the instructions on your web site, and it indicates that you must dump the contents from an actual physical ROM (for copyright reasons, which makes complete sense). I've tried this and failed because the MathROM appears to be private and I don't have the alternate PEEK$ LEX file needed to unprivate the ROM. (in fact, I don't know which PEEK$ file is needed -- will the one on JPCROMD work? Apparently, the PEEK$ keyword was removed on JPCROM Ex).
But I've read in this thread and a number of times here in the Forum and in Datafile (Valentin's *superb* HP-71 articles) that the MathROM is *included* in EMU71, which seems to contradict the above.
Since I haven't yet found a MathROM file in the EMU71 download, I'm assuming the instructions on your web site still apply. But now I'm wondering, if the MathROM code is actually available in a LEX file on one of the swap disks (which I was unaware of until seeing the posts in this thread), doesn't that mean the ROM code is already in the public domain? It looks like I could download the LEX file into EMU71 RAM, but can a binary file be created to include it in ROM on EMU71 (without violating any copyright restrictions)?
Best regards,
Chris
