I never really used libraries with my 48G, 48GX and now my 49G+. I really like the HP line. However, I have become extremely use to the equation library on the 48 series. I have researched on hpcalc.org. They indicate that Libman was a good program to manage libraries and eql49r27 was a good library to replicate the equation library. However I have no idea what I am doing with the libraries, how to install them or how to run them. the directions for the programs are clearly for someone who knows what they are doing. Please help me with any advise. Thanks.

Hi, since you have at least two HP-48G type machines, you propably still have the user manuals. Installing of libraries should be explained there. I don't know the quality of the 49G+ manual, but if it's like the 49G manual, then go for the 48G manual. However, there are FAQs on www.hpcalc.org covering the topic of libraries. Raymond ▼

As for installing the libraries, I agree with Raymond. It's essentially the same since the 48SX. There are a few differences though. The 49g+ has the SD card as port 3, but libraries won't work from there, you have to use ports 0, 1, or 2 for active libraries. The File Manager application is perhaps an easier way to move the library to a port. For the 49 series, turning the calculator off and back on no longer executes the library configuration routines. Do an ON-C warmstart after storing the library in a port to run the configuration routines. If you have a misbehaving library, you may want to have them all detached so you can find and purge the buggy one. On the 49 series, hold down the backspace key while doing a warmstart, which bypasses the configuration routines, so no libraries will be attached. Except for I/O and the SD card, the 49g+ is very much like the 49G, at least as far as UserRPL goes.
As for the 49g+ user's guide, in some ways, it's a big improvement over the 49G, but it lacks an "Advanced User's Guide" with information on each command. I suggest using the 49G Advanced User's Guide with it. See http://www.hpcalc.org/search.php?query=advanced+user%27s+guide&hp49=1 In general, keep in mind that most of the information on older model RPL calculators still applies to the newer models. ▼

The 48 series calculators are still amazingly useful products with Quote:Sorry about that. I think that the manuals mention the [ON] and [C] keypresses together operation to exit the system tests, but I don't know that they bother to give it a name. And yes, the 48 series automatically does the warmstart for you, if you haven't already done it yourself.
I suppose that a "cold start" would be just turning the calculator on
What's commonly referred to as a "warmstart" is what Bill Wickes calls Quote:
Note that the 49 series don't do a warmstart on turn-on just because
Ordinarily, all keys except [ON] are put into the key buffer as soon
A warmstart may be needed if a buggy operating system or misbehaving
But sometimes the crash is so bad that even the [ON]-[C] operation
A paperclip reset also adds an entry similar to "C-03/20/04 21:35:31"
As I mentioned in my earlier post, on the 49 series, holding down the
Most libraries seem to include an ATTACH command as part of their
On the 49G, [ON] and [D] together gets you to the "Tests" screen, and
The 48 series doesn't have a built-in way to bypass the library

James Prange gave a great explanation of warm starts as they relate to HP calculators, but I thought I'd add a bit of other HP trivia. Some of these terms probably were borrowed from HP's HP3000 minicomputers and their operating system, MPE (Multi-Programming Executive). Back when I was an HP3000 system manager, this was the procedure we followed after an unexpected crash (system halt): (1) Perform a memory dump to tape so HP Support could look at it if necessary. (2) If possible, bring the system up with a warm start, which preserves in-memory tables, temp files, spool (print) files, etc. (3) Print the spool files or dump them to tape. (4) Shut the system down again. (5) Bring it up again with a cool start, which clears spool files and temp tables, and loads the operating system into memory from disk. (6) If the system wouldn't come up with a warm start or cool start, the next option was a cold start (also called cold load) which copied the essential parts of the operating system from tape to disk and then proceeded like a cool start. (7) If all else failed it was time for a reload, which cleared the disk packs and loaded everything from tape. This was a drastic last resort and usually was the time that you discovered one of your backup tapes had a read error. :-( After a normal shutdown (as opposed to a crash) a warm start was all that really was necessary, but we usually did a cool start because it took very little more time and we liked knowing all the temporary stuff had been cleaned up. An HP3000 warm start was much like a normal "power-on" for an HP48, the 3000 cool start was similar to a 48 warm start, and a 3000 cold load was something like a 48 TTRM. I guess the closest 48 equivalent to a 3000 reload would be clearing all the ports on a 48 expansion card and reloading them from a PC backup.

Hi,
if it's mainly the filer you like, then I'd suggest to try Filer48 from Raul Del Cid Lopez. Regards, Raymond

I need help in finding a program to copy text files onto my HP 49G +. I've tried WinHp, but sadly it's only for the 49G, so there's alot of dot ect... that doesn't belong... Please Help! |
