- Draft 0.1 of comp.sys.palmtops's unofficial HP-95LX FAQ list:
-
- Well, here is a really short list of questions and answers. Please feel free to
- correct me. Again, if you have any suggestion, please email too.
-
- ======
- Q) What FTP sites are available for the HP 95LX?
-
- A) There are two sites:
- eddie.mit.edu:/distrib/hp95lx
- col.hp.com:/mirrors/hp95lx
- Obviously, the HP site is merely a mirror of MIT. Use whichever is closer to
- you. Portions of this FAQ have been gleaned from various files on these sites.
-
- ------
- Q) How many version of ROM's have there been for the HP 95LX and what bugs are
- available in each revision?
-
- A) I still don't have an answer for this one. I do know that my 512K's ROM is
- dated 04/02/91. At the very least, can everyone please email me their ROM
- revision so that we can have a list. Please include whether your 95 is the 512K
- or the 1M version. (To check your ROM revision, just turn off your 95 and hold
- down the ESC key while powering it up again.) As well, there are several
- revision of the manuals. Can everyone just email me their manual revision along
- with their ROM?
-
- ------
- Q) Why does my 95 emit a high pitched whine when it is on? It get's louder when
- a key is pressed.
-
- A) The sound that you hear comes from the voltage conversion required to drive
- the screen from DC. A similar sound can be hear on the HP-48s[x]. Using HP's AC
- adapter (which outputs AC) will eliminate the whine.
-
- ------
- Q) What kind of AC adapter can I use with the 95?
-
- A) The 95 can accept both AC and DC (either polarity) from the AC adapter. The
- HP adapter outputs 9V AC and 13.5 VA max. People have also used 9VC DC adapter
- with success.
-
- ------
- Q) Why is the hinge on the left hand side slightly looser than the right hand
- side?
-
- A) According to an HP employee, the hinge was built with only one clutch on the
- right hand side to reduce cost. This is the cause for the loosening.
-
- ------
- Q) I heard that there are some games in the ROM. How do I get access to them?
-
- A) Only the US-English version of the 95LX contains these games. The two games
- are `TigerFox' and `Hearts & Bones'. A standard command-line version of
- `TigerFox' is included as C:\TF.COM. All version of the 95 contains a hidden ROM
- directory C:\_SYS\. Both games are in what is known as System Manager Compliant
- format and have the extension .EXM. .EXM-type programs behave just like the
- built-in application in that you can hot-key back and forth between them.
- .EXM format program requires some slight amount of work to setup. Use the editor
- to create the file C:\_DAT\APNAME.LST with the following:
-
- --
- C:\_SYS\TFOX.EXM,1400,TigerFox
- C:\_SYS\HB.EXM,2300,Hearts & Bones
- --
- Then reboot. Now, Alt-T and Alt-H will start up `TigerFox' and `Hearts & Bones'
- respectively. In general, APNAME.LST controls what .EXM programs are installed.
- The format for each line is:
-
- <pathname of .EXM>,<scancode of key>,<full name of program>
-
- ------
- Q) How do I find out what the scancode is for a particular key sequence?
-
- A) Grab the file tools/hp95dev.zip from either FTP site.
-
- ------
- Q) Where do I start if I want to write programs for the 95?
-
- A) Grab the file tools/hp95dev.zip from either FTP site.
-
- ------
-
- Q) The soft plastic holder for the backup battery seems to be rather fragile.
- Does HP sell any replacement? I'm just afraid it's gonna break one of these
- days.
-
- A) Haven't tried calling up HP on this.
-
- ------
- Q) How do I get the 95 to generate phone tones suitable for a touch-touch phone.
- Is this possible?
-
- A) Try others/dialtone.zip from either FTP site.
-
- ------
- Q) Where's the cheapest place for a 1 or 2Mb RAM-card?
-
- A) The best price for a 1Mb card so far seems to be EXP Computer (516)496-3703.
- As of two months ago, they were working on a 2Mb card.
