The 48 series' thin all-plastic keyboard was not quite as reliable as now wistfully thought; I've read many a time of individual domes cracking and/or failing (sometimes just the ON key, which is a little bit vital), and other durability problems, e.g.: http://groups.google.com/group/comp.sys.hp48/browse_frm/thread/d6943dcf4b739eb8 http://groups.google.com/group/comp.sys.hp48/browse_frm/thread/6c0b0e513a33b119 http://groups.google.com/group/comp.sys.hp48/browse_frm/thread/b63c1a760c59f506 http://groups.google.com/group/comp.sys.hp48/browse_frm/thread/9087b0ad86aa9763 I have never experienced nor read of a keyboard failure on a Voyager (11C-16C) nor even a Pioneer (32S,42S,17B), nor the *second-generation* Spice (31E-38C) with metal discs (whereas *first* generation Spice was a disaster, much like you-know-what); how about you Coconut (41) owners? All-plastic keyboard construction in 48 series: "The guts of the HP48 keyboard are assembled from several layers of mylar and similar material. Some of the layers have *conductive*ink* to create switch contacts. Some are insulators, with appropraitely located holes through which the switch contacts meet. Some are embossed with spherically domed areas, to provide the snap-spring feel when you press the plastic keys. The entire multi-layer sandwich is assembled onto plastic pegs on the backside of the HP48 top case, along with the metal chassis, and then the pegs are 'heat staked,' positively capturing and holding the matrix together." http://groups.google.com/group/comp.sys.hp48/msg/dd7f9885f92f0a7d Here is a keyboard rated by its sound: "My impression of the 49G+ keyboard is that it's very robust and built to last forever. The keyswitches remind me of an old italian motorcycle I used to ride (Laverda SF750). They clunk into engagement with a commanding sound that lets you know you're in gear. Bulletproof." http://groups.google.com/group/comp.sys.hp48/msg/e7309aac57866983 [posted Jan 7 2004, most likely a *first* generation keyboard] [r->] [OFF]

You use the PC's USB port and the mini-USB cable that comes with the calculator. It was the 39G & 40G that used a serial cable but so many computers come out now without a serial port that they changed things in the 39g+ so that it used the USB port instead. The mini-serial port on the 40gs is for communication calculator to calculator via the second cable in the package.
From: jajacom on 23 Jul 2006 12:46 Ok! With HP 40G to download an language machine program I was using Hyperterminal. Now with HP 39G+ or HP 40GS with USB it doesn't work anymore. So how can I proceed? Where can I find a X modem soft running on HP 39G+ or 40GX?

So if you didn't want to use HP's software (HPGComm) then you could use Hyperterminal. This is not the case with the 40gs. It's default method of connection is to use USB. I'm not a user of Hyperterminal but I have the impression that it isn't a USB program? So, how to connect a 40gs to a SERIAL port... I honestly don't think you can. Although the 40gs has a serial port it is not a standard one. The connector is a "mini-serial" and the only cable I've seen that connects to it is the one that comes with the 40gs. This is set up to connect a 40gs to a 40gs, not a 40gs to a PC. I think I've read on another thread that this cable is not a standard one (lower voltage) so I *really* don't like your chances of finding another cable with mini-serial on one end and a DB9 plug on the other. If you find one then PLEASE let me know! What I don't understand is WHY! Why would you want to use Hyperterminal and the serial port when you have a ready supplied USB cable and software ready to use? |
