See the announcement for Firmware V26 for full details and a link to the firmware.
A bug that caused corruption of registers allocated to matrices during a numerical integration has been fixed and backported to legacy DM15_M80 units built on the LPC1114 chip with 32KB of ROM.

Re: Firmware V16a for legacy DM15 M80
A short question: After flashing, the info screen (E+On) still shows version 16 for my legacy 32k DM15 M80 (and not the anticipated 16a). Is this correct, or did I something wrong, and so I have still the previous version 16?

I think you're still good do go.
You can check this by putting the machine in the situation that caused the problem.
Reset the machine with the [ON]+[-] key combo to get the usual "PR ERROR"
Write a small program to give the integrator something to chew on:
...is sufficient.
Create a matrix A of 7x4 elements: 7 [ENTER] 4 [DIM][A]
And a matrix B of 2x2 elements 2 [ENTER][DIM][ B ]
Reset the matrix pointer and observe that B[1,1] is zero: [MATRIX] 1 [RCL][ B ]
Perform the integration: 0 [ENTER] 1 [INTEG][A]
View B[1,1] again: [RCL][ B ]
If you get 0 then you have the correct firmware and it simply doesn't display the "a" (which I suspect is the case). If not then we have to think again!

Thank you very much for the quick, and detailed reply! Since I've got 0.0000 as the result of the test above, all is fine for both of us.
