I assume this is on the bottom of the PGA2350? That's a view I've not seen.

Thanks Jim, for posting the illustration. (Excellent macro-photography, by the way.)

Just for clarity, the arrow marks the point of cut/connection and the solder pads for reversal.

Not my photos. Compliments of the Pimoroni website.

I had an idea this morning. Apologies for going back on topic. :)

VAR SAVE PSRAM var1,var2 [,var3 ... ,var8]
copies the variables into PSRAM
variables must exist. arrays must be DIMed.

VAR RESTORE PSRAM var1,var2 [,var3 ... ,var8]
overwrites variables with copies from PSRAM
if variables don't exist they will be created using types & values from PSRAM.
arrays will be deleted first then recreated from the PSRAM using those dimensions.

VAR ERASE PSRAM var1,var2 [,var3 ... ,var8]
erases the named variables.
this may not be sensible unless the PSRAM space can be re-used.

VAR CLEAR PSRAM
clears all the PSRAM

mm.imfo(PSRAM SIZE)
returns the size of the PSRAM

mm.info(PSRAM USED)
returns the amount of used PSRAM

And for those who are masochistic programmers...

VAR DISK PSRAM "filename"
saves the content of PSRAM to disk as filename.PSR
it may also need to save filename.PNM
which is a CSV file of the variable names, complete withj array dimensions and string LENGTH values so that variables can be recreated later.

VAR LOAD PSRAM "filename"
restores the PSRAM content from the disk file.

VAR MOVE PSRAM var1,var2 [,var3 ... ,var8]
moves the variables from the variables area to PSRAM by copying them, changeing the pointers to the new address then deleting them from the variables area.

Phew... I had to get that out of my head before I could think of other things! :)
