Well, I'm soon to be the owner of an HP-48SX, which I ordered a few weeks ago. Anyway, I have several questions about the ROM revisions I keep hearing about. 1: Everyone seems to have ROM Rev. A. Does any other revision even exist yet? 2: When a new ROM revision is released, what kind of upgrade path is available, and how much can one expect to pay for it? 3: This last may be a dumb question, since it may be marked on the calculator, or more likely the manual tells you how to find this out, but since I don't have the thing yet, I thought I'd ask how you identify which revision you have?

I've seen and played with a 48SX with a ROM Version "C". I've heard (in comp.sys.handhelds) that version "D" exists, but I haven't seen one. > 3: This last may be a dumb question, since it may be marked on the > calculator, or more likely the manual tells you how to find this out, > but since I don't have the thing yet, I thought I'd ask how you > identify which revision you have? Instructions are at the end of this message. These instructions were originally posted here some time back. -- Darryl Okahata darrylo%hpnmd@hpcea =============================================================================== From: madler@tybalt.caltech.edu (Mark Adler) Date: Sun, 11 Mar 1990 03:19:51 GMT Subject: Re: hp48sx ROM revision Organization: California Institute of Technology, Pasadena Newsgroups: comp.sys.handhelds I neglected to say in the ROM bug listing how to tell the ROM revision. Here's how: 1. Turn the calculator on (press ON and then release). 2. Press ON again, and while holding it down, hit the "D" key (the fourth white key in the top row) and then release the ON key. You should get three vertical lines in the display, one down the middle. 3. Hit the backspace key (it says DROP and CLR over it). You should get some meaningless hexadecimal in the first line of the display. (Mine says 705D9:1B8D...). 4. Press and hold down the EVAL key. It should say: Version HP48-* Copyright HP 1989 where the * is an uppercase letter (A, B, etc.) indicating the ROM version. 5. Release the EVAL key. Hold down ON and hit "C" (the third white key in the top row. This is a general reset operation that returns the calculator to normal from the diagnostic stuff (which is where ON-D puts you). I'd be very interested if anyone gets anything but revision A. Mark Adler madler@hamlet.caltech.edu

I have ROM rev. C. There aren't too many differences (but a few. The matrix >= 8x8 inversion problem still is there, but several minor bugs, like KERMIT handling file size 0 and other things seem to be fixed) I also have a 32kb RAM card (HP original) and a mac interface, and I'm very pleased with both. If I ever get to making a decent non-cryptic version of the time-manager software I'm hacking on, I'll post it here. > 3: This last may be a dumb question, since it may be marked on the calculator, > or more likely the manual tells you how to find this out, but since I don't > have the thing yet, I thought I'd ask how you identify which revision you have?

Thanks for posting the instructions. I got mine two weeks ago from EduCALC. It still has the Kermit "Arrow" bug and the 8x8 matrix inversion bug. A page of "Important operating tips" mentions a few others, such as transferring a zero-length file with KGET may clear memory. -- Dave Seaman ags@seaman.cc.purdue.edu

I have had my HP48 since mid April, and it is a Rev B ROM.
I have seen a lot of people asking if HP will offer ROM upgrades,
but so far, HP has remained silent.
To find out the Rev. level, you have to do the following:
1) Turn the calculator on.
2) Hold down the ON button and press the D button (4th button, top
row). Then release both buttons. This puts you in a testing
mode that can be used to test the hardware.
3) Press the button with DROP/CLR above it. This is the last button
on the row with the Enter button. This should display a HEX
address and some HEX data on the top row of the screen.
4) Press the EVAL button. This will display "Version HP48-x" on the
top line, where x is the revision level (A, B, C or whatever).
This will only display for 2 seconds before the HEX dump line
comes back. If you want to see it again, push EVAL again, or
you can hold the EVAL button down.
5) To return the calculator to normal operation, hold down the ON
button and press the C button (top row, third button).
This is all documented in an addendum that came with the calculator
that lists known problems by rev. level. There are only 6 problems
listed, and all but two only apply to rev A. The others are listed
as applying to revs A,B,C and A,B,C,D respectively.
HP has a free bulliten board for people interested in the HP48. The
phone number is (503) 750-4448, and it supports 300-2400 baud, and
they have some lines that support 9600 baud V.32. The phone number
also comes with the calculator.
Even though the bug sheets mention rev levels through D, I have not
seen anybody here or on the HP bulliten board claim to have an rev.
levels higher than B.
