All of a sudden virtually nothing works. Tried to run all the
diagnostics in the manual, tried hard reset. Batteries fresh. So how
do I penetrate the HP web pages to get a repair estimate - anyone
know. Where are the good places to buy a new 48GX, if it comes to
that. I suppose the 48GX has been superceded, but the reason I want to
stay with the 48 is that I have a 128K ram card for it.

Ideas or advice - send to jwfe...@ties2.net

Thanks.

Amazon.Com or eBay.

All the current HP graphing calculators have more RAM than that built-in. An
HP-50 (HP's current "top end" machine) is $115 at Amazon has 512kB whereas the
cheapest graphing machine, the 39GS for $68, has 256kB.

Would the 128K ram card that fits the 48GX fit and work in the 50? I
know about Calc Pro - are they reliable still?

I'd guess it is the data on those cards that is more of a concern.... Good
reason to get the PC connection package, although it looks like Jack is on
a Mac and I don't know how well that works out (too late now anyays). I'm
in the same boat - when the HP48 dies, I'll lose everything on it because I
have never bothered to buy the connection stuff and figure out how to get it
working under Linux.

What is the functionality difference between the 48GX and the 48GII
and 50G, other than memory.

BTW, I went over to Yahoo Groups and found the HP48 group. Checked
back messages to beginning of October this year and did not see one
single post that was about the 48 - all 52 posts were pure spam. There
were 10 HP calculator groups and most were less than 15 members. Is
this group plagued with spam and are there few active folks. Ten
years ago things would have been different. I still have my PPC Rom
Users Manual from 41C era.

Please take a look at www.hpcalc.org ,
where you'll find almost everything about
the different HP-48, 49x, and 50g machines.

To make it short, forget all machines numbered 49-something,
and even the so-called '48gII', which is basically a stripped-down '49g+',
and has nothing to do with an HP-48.

For a comparison I'd concentrate on the HP-48 G series and the 50g...

BTW: If you intend to keep your real HP-48,
or even buy another unit,
be sure to take a look at SpeedUI (on hpcalc.org),
the software turbo for the HP-48 G series!
With SpeedUI installed, there are not many reasons left
to use something other than a real HP-48;-)

The 49 and 50 series cannot take RAM cards.
But with the 50g or 49g you can use SD-cards as a mass-storage.

Found an 800 number for HP Repair services and learned HP doesn't fix
calculators. Of course, had I read www.hpcalc.org first I would have
surmised that. Anyhow, HP gave me a web URL that does fix HP
calculators: fixthatcalc.com (no www). Went there I found a price of
70 bucks to fix the 48GX. So far that is the least costly option.
Anyone have any experience with them?

The HP48GX can "talk" using "serial over IR" [SIR],
which offers wireless connection to other gear of similar competence;
otherwise one can get a still-available serial calc cable (or build one),
perhaps to a USB<->Serial at computer end.

The HP48GX also "speaks Kermit and Xmodem" (file transfer protocols),
which are very commonly available for computers of every description, and
nearly always built into "terminal" programs, such as Windows' HyperTerminal.

I used fixthatcalc a couple of years ago to fix an HP-42S. In my case,
they did what they promised, in a reasonable amount of time, for a
reasonable cost. YMMV
