You have to activate RAM in BLK5, right, so there's something you can load the SE cartridge dump into (with LOAD"...",8,1).

But you also have to activate at least RAM in RAM1..3 - so the SE ROM has some extra RAM to work with. That's especially important when you want to work with graphics.

Then, a simple Reset will activate the Super Expander, via its built in cartridge signature.

With a +3K RAM expansion alongside (what is normally built into SE) you'll see 6519 BYTES FREE on start up - a bit less than 6655 as with a 'standard' +3K RAM expander. No extra 'fancy' message, like "Super Expander activated", or the like.

The original poster is asking for technical information in french so I will reply in french. Please notice me immediately if you feel this is a violation of forum policies.

See my own answer above. I think we are fine with that.

You can check if the Super Expander is active by typing the command KEY which doesn't exist in BASIC V2.

If Super Expander is active, it will give you a list of shortcuts assigned to the function keys. If not, you'll get a syntax error.

when i set SW5 to off, and reset , i have 3447bytes free instead of 19kb if i have config with 16k....

to be sure, i set SW 1,2,4,5,6 to on, other on Off

i type load "superexp",8,1

Switch sw5 to off and reset or sys 64802

right ?

The hardware configuration of Super Expander is replicated on the +37K RAM expander as follows:

- DIP switches 1 to 3: OFF
- DIP switch 4: ON
- DIP switch 5: ON (for 'normal' setting)
- DIP switch 6: ON
- DIP switch 7: OFF
- DIP switch 8: ON

Then, LOAD "...",8,1 of the Super Expander ROM dump.

Ideally, you should now set DIP switch 5 to OFF (i.e., 'read only') so the cartridge image is write protected, and then do either a reset or SYS64802.

Then, check with KEY whether SE is there. And again, it should show 6519 BYTES FREE.

@eslapion: corrected DIP5 action. Thanks!

Why set the RAM to read only ?

to be sure, i set SW 1,2,4,5,6 to on, other on Off

i type load "superexp",8,1

That's OK.

It will give you a Super Expander with 24k expansion.

Switch sw5 to off

NO!

and reset or sys 64802

Yes!

SW5 to off sets the 32k RAM to read-only and that's useful for many cartridge games which try to self-destruct as a means of copy protection. SE doesn't do that and can use RAM in BLK 1,2,3.

If you ABSOLUTELY want to set the 32k RAM to read-only for whatever technical reason then you'll need to add the 3k RAM expansion (set SW8 to ON) and this will give you exactly the same configuration as a real SE cartridge.

ok

now it works with 28kb.... thanks !
