Quote:How to move lexfiles from PC to 71 w/o HP-IL?
Message #1 Posted by Joe Horn on 11 Oct 2013, 9:55 a.m.

Help, please. If I don't have a PC-to-IL converter or card, how can I take HP-71 lex files in binary form on my PC's hard disk, and get them into an HP-71?

Back in the 71's heyday, a popular method for transferring lexfiles was in a kind of hex dump with checksums at the end of each line or at the end of the entire dump. But the conversion from binary to hex dump was also done on the HP-71. Is there a PC utility that converts lexfiles in binary form into hex dumps that can be typed into the HP-71 and converted there?

I'd use LIF2DOS or LIFUTIL if I could, but all my LIF disks are apparently unreadable. :-( So I'm stuck with the binaries on my PC's hard drive.

Thanks in advance for any help you can offer in this regard.

FWIW, my ancient collection of HP-71 lexfiles is now available online:

Brief descriptions of the most popular lexfiles:
Zipfile of complete lexfile collection (binaries):
Zipfile of all the related text files (docs and/or source code):


Others may have already done this, but here are all the individual LIF files in compiled into a single LIF image, like the HPSWAP files on the FTP site.[attachment=397]
