Normally, the function RESPR(0) will return the address of ramtop, this can actually be used to find out the size of memory attached to the QL
PRINT RESPR(0)/1024-128

Hi,

You could load Toolkit 2 and use the FREE_MEM function. Or upload a photograph with the cover off.

Hi,

Most PCML interfaces had 256Kb of ram, from the blurrly photograph, the memory chips look to be 256 chips.

You always put the interface into a QL with Minerva installed, which tell you how ram the system holds.

Derek
