HP49 problem (bug?)
Steindor E. Sigurdsson
Home directory.
The following is an example of a sequence of actions that causes my 49G to
freeze (on both 1.10 and 1.16).
PLOT(X) [ENTER]
[->] [TABLE]
[->] [TBLSET]
|
V (down arrow tvice, to ZOOM)
[F6] (OK)
Could someone try the above and let my know if this is just a bug or if i
might have a damaged calculator.
I don't know wheter it is relevant but when I turned it on for the first
time I got two messages, "Invalid card data" and "Try to recover memory?".
Any ideas?

not following exactly your steps (I didn't fully understand what you
meant)...anyhow, suddenly it crashed and stated "Recover Memory"...so, it
might be a bug after all...but again, this might be pure coincidence since I
didn't follow exactly all your steps!

sorry)
Type PLOT(X) and press [ENTER]
Press "left shift" (blue left arrow) and then [TABLE] (F6)
Press "left shift" (blue left arrow) and then [TBLSET] (F5)
Press [F6] (OK)
Like I said earlier, I've been having problems with my HP (halts and memory
corruption) so I'm hoping that some feedback could help me figure out if
this is caused by an unstable operating system or if I just got a faulty
calculator.
Also,
does anyone know what "Invalid card data" means?

Hello.
I can't reproduce any problems using your key sequence on any ROM
version (1.05, 1.10 and 1.16)...
What version are you using ?
In order to get rid of the "Invalid Card Data" type the PINIT
sequence...

the screen or responds with "Try to recover memory?").
And this is not the only thing that causes problems, just the only sequence
I've noted exactly and been able to repeat (it has also happened while
running games for example).
Like I noted in my first post, when I turned it on for the first time it
responded with "Try to recover memory?" and "Invalid card data", I was
wondering if that might indicate problems with the machine itself.
My main concern is therefore, could this problem be related to software (and
hence fixable) or hardware?

You shouldn't swear by games' stability.. Some may crash ! Just run a big
UserRPL program,
or try running some safe Assembly program to check whether it happens..

I don't think so.. I guess it's because the RAM contents were undefined when
you
bought the machine.

Maybe your hp's RAM is not reliable.. The TRM never happens with my machine
(rom 1.16),
except when I'm coding and running bad Assembly programs (but that's another
story..).
A garbled screen happened only once, and ON-C did the job.
You should run some test program ! Also, try ON-D to check the RAM ..

It's either a hardware fault or a bug if any user action
causes a crash.

Yes, I tried these keystrokes, and the screen was frozen, and a bit
later, many vertical lines , then the happy message:
Try To Recover Memory? My user memory was not erased, but I have
experienced some different situations with the same result.
There are many bugs which cause memory corruption. Therefore, I have
seen many others which was fixed succesfuly.

anyway to avoid the "invalid card data" message type PINIT, it should
go away.

1.14-2, 1.15-5 and 1.14-7. Many bugs in older versions are fixed in
later versions fortunately, but not all.
The problems are not with "invalid card data", but with warm or
coldstarts, depending on situation. For an example, when I was editing
programs in sys-rpl, and press [enter] without compile nor run it, the
editor causes a warmstart. The memory was not corrupted, but the stack,
pict etc. was lost. Many other crashes occur in various situations.
These situations are unpredictables.

I'm using the editor A LOT, and I haven't had any warmboot since 1.14-3.
I think they changed something in the interrupt handler after the 1.14-2,
but I don't know if this is related.
Besides, I couldn't reproduce your keystroke sequence to crash 1.16.. Could
you be more precise ?
Thanks

I could reproduce the bug on both my real machine
and on the emulator, both with ROM 1.16, using the same
key sequence, entered immediately after a full reset,
in *algebraic* mode.
Instead, I was *not* able to crash the calculator
in *RPN* mode, possibly because in RPN mode the left-shift(hold)
TBLSET shortcut does *not* work while TABLE is active, so
I was no able to start TBLSET without exiting TABLE first.
Hope this helps,
Ivan

This is about as precise as I can be:
Type PLOT(X) and press [ENTER]
Press "left shift" (blue left arrow) and then [TABLE] (F6)
Press "left shift" (blue left arrow) and then [TBLSET] (F5)
Press [OK] (F6)
"Works" every time, halts the machine on both ROM 1.10 and 1.16 and on
"ON-C" responds with "Try to recovery memory?"

Reproduced here on 1.16. These are my flags (yes that's algebraic mode).
{ # 3080018402A14FF0h
# 1000000000000000h
# 18010442000000h
# 0h }
Note also that:
Plot type FUNCTION is necessary. I had 'X' stored in EQ.
And "halts the machine" means it hangs with the hourglass on.

You're right ! Sorry.
If happens on mine (it locks up), but only in algebraic mode.
Thanks, I'll report it to them.

Thank you for this interesting mode...
Unfortunately, to fix it I had to disable the TaskSwitch capabilities of
the HP49..
Fortunately, it was not used *yet* :)

Multitask?
Garcia Garcia, Cesar F.
Like Windows?
and
Without getting blue-screen errors two times out of three?????

The point is to set the display blue! (and be Microsh*t compliant)
This shows the famous HP 49G preproduction "Blue Screen":
