About this MSX1 RAM config.
________________________
PEEK(&HFCC1)=0
PEEK(&HFCC2)=0

INP(&HA8))=0
PEEK(&HFFFF)=&HF0
0-0:[0000-7FFF] MSX ROM
0-0:[8000-FFFF] 32KB RAM
1: SLOT
2: SLOT
3-0:[0000-7FFF] 32kb RAM
3-3:[4000-BFFF] 32kb ROM WORD PROCESSOR + DISK RAM
It is not compatible with programs which use RAM in the same slot /subslot.
- it's able to relocate 32kb chip (?) RAM to 3-0 slot?
- or the solution would be to add more RAM? How?

Officially you need to search each slot for RAM in a certain page. Once you know where it's located for that page you can do anything you need with it.

Try to use the MemTR program for this.
The MemTR was developed by Armando Perez.
In Hans Otten's website you can get the MemTR program.

I think MemTR just selects the slot with the bigger memory mapper, and modifies system variables to use it. So it can't handle RAM in different slots. |

Where can I get this program? (MemTR)
I have Padial's 4MB mapper and I want to get 64K with it on my 32K MSX1 machine.....
