Am I to understand that people other than Mark are finding V3.10 to be unstable? I'm not talking about the excessive power consumption when off, I mean the device crashing.
Yes, I was able to reproduce another error on two different devices (SN00480 and SN00155).
For example.
Input:
5
ENTER
1E10
y^x

Now the machines freezes!
Then I run DM42 3.9.1 on DMCP 3.10 like Mark Hardman did and all worked fine ("Out Of Range" or 1.E6145).

On machine with SN00480:

Bench with DM42 3.10 on DMCP3.10:
I tried 1E4 on USB, ok.
I tried 1E4 on Battery, the machine freezes.

Bench with DM42 3.9.1 on DMCP3.10:
I tried 1E4 on USB, ok.
I tried 1E4 on Battery, ok.
I can confirm that mine crashes as well. SN 00245.
Just to note; mine crashes also connected to USB power and voltage indication 3,02V (5^E10)

Reverting back to 3.9.1
No crashes.
5^E10 returns "out of range"
Bench 10.000 takes abt a minute and returns 13.955,8579043 after abt a minute.

So, sticking with the 3.9.1 for the time being.

My DM42 (beta unit #62) freezes after a couple of seconds of ijabbott's BENCH example (with X = 10000), and also freezes when I do 5 ENTER 1e10 Y^X.

Battery voltage is 2.88 V. No USB power used. I ran both tests only once, since I wasn't interested in how often these freezes occurred on my calculator, but only whether they occurred at all.

See this message above (viewtopic.php?p=9071#p9049)

However, there are multiple benchmarks available so we need to get clarification from Mark regarding which benchmark it is that he used.
Sorry not to be more specific about which BENCH I was using.

Here's the code I'm running:

Code: Select all

01 LBL "BENCH"
02 STO 00
03 CLST
04 LBL A
05 RCL 00
06 ATAN
07 SIN
08 E^X
09 3
10 1/X
11 Y^X
12 +
13 DSE 00
14 GTO A
DM42 S/N: 00043 (Beta)
DM42 S/N: 00065 (Beta)
DM42 S/N: 00357
