HP-71B - Clockdsp Line 23 Message #1 Posted by Roland Storz on 22 May 2008, 6:35 a.m. Hi All, in Joseph Horn's ebook "HP-71 Basic Made Easy" you find the Lex File "CLOCKDSP". However, in line 23 there must be an error, or I do have a bad copy. For me it seems to be impossible to get that line entered correctly. In my printout of the ebook the line reads as follows: 023: E061 5101 F174 F233 BE What is wrong with this? Any help is very much appreciated, Thanks, Roland

Cheers, Geoff

It makes the Digits graphically, smaller than the standard ones, leaving more digits for the normal display. Warning, take care not to have both programs in memory, they both use CLOCK ON/OFF Greetings, RamLab

Re: Had the same problem...try Message #7 Posted by RamLab on 25 May 2008, 3:45 p.m., in response to message #6 by roland storz Hi, The great thing about the HP41/71 is that there have been a lot of programs written, and published in several magazines in the mid 80's. The other great thing is, that several people have put a tremendous effort in preserving them, by scanning them, and making them available to "later" HP41/71 users/lovers. One of them is Warren Furlow. Download EMU 71, install it on you PC, than go the the LIF archive, ftp://ftp.math.jyu.fi/pub/hpil/swap/chhu04/ and include it in EMU71, than you can list you LEX file. RamLab
