Does anyone know if an ECO exists to convert a REV11
board (M9400) to
22-bit
BTW, it appears that that board (in some configurations) is also known as a
TEV11.
in the same way that an ECO exists to convert
BDV11's to 22-bit? (On
the BDV11, there's a resistor pack with 4 unused pull-up/down pairs
So I located a set of prints for the TEV11 (which I must scan and get to Al,
they don't appear to be available online), and on the M9400 there are four
spare pull-up/down pairs, although not all in one package. They are:
E6-1
E17-1
E17-12
E27-15
I have verified that these are free (looked at a board, no traces to those
pins). (And yes, the 1 pin is usable - it's used in E27.) Not all in the same
package, so the ECO will be a bit messy, but it can be done.
Guess I should read out the ROMs, too (assuming they haven't already suffered
bit rot).
