is there a program wich will tell me how many memory a msx has.

i have 2 msx computers

1 nms 8245
1 nms 8250

both have extra build in chips , i think both are a memory upgrade.

thank.

i have runned the program

and it says it has 256kram in slot 3 and 2

does this mean there is a total of 512 kb in it.

i do not have i msx standard to test it on.

Would that be slot "3-2" ? Question (usual place where Philips MSX2's have their RAM). If so: that's just 1 (one) slot, and it would mean this machine has memory mapper expanded from factory 128K -> 256K.

Is this the 8245 or the 8250? And the other machine?

it's a 8250

it has a extra little board in the machine, wich is connected with a bunch of wiring to the original
ic's on the msx board it self

the extra print, looks factory aftermarket.

but the wiring is flatcable type

i was also thinking about twice 256kb
but if i am correct the 8250 only has 128kb ram
so that would be have doubled and is now 256kb ram

correct?
