I'm using V1.32 of EightyOne.
Using TS1500 setting and TS1500.ROM (with RAMPACK set to none) I get Ramtop at 32768 which is correct.
But DIM A(1000) crashes the TS1500.
If I add a 16K Rampack ramtop doesn't change (I'm not shure if thats correct) but DIM A(1000) works.
If I use the ZX81 setting with no RAMPACK and TS1500.ROM DIM A(1000) gives error 4
Again, with 16K Rampack added, DIM A(1000) works as expected.
Using TS1500 setting and zx81.edition3.rom with no RAMPACK DIM A(1000) gives error 4 which is unexpected

This combination also gives just 17408 as Ramtop

Am I doing something wrong?
