Referring to that discussion, I can see a downside to remove it if you use headphones directly with the MIST. I do so will keep it for now...

OSD also provides menu where you select the disk and then press enter to run it.
Sorgelig wrote:So, the only advantage of HDD is multi-disk apps where you don't need to change the disk manually. But honestly it looks like magic. How app will know which disk to load next?
When you have 4MB of external RAM, two disk drives are not enoughSorgelig wrote:By the way, aren't multi-disk apps aware of second drive provided by core?

Sorgelig wrote:Can you recommend application to test writing? I'm not familiar with SAM Coupe software.
It can be some file copy program or similar.

As far as i know it's mapped to cursor keys.
SirDavid wrote:Besides, why have you done real CPU frequency for ZX mode? It's great, but why use it instead of ZX core?
SirDavid wrote:You can change the record by " RECORD "name" " and names could be "demo_a_disk2", "demo_a_disk3" and so on.

SirDavid wrote:You can simply use BASIC (SAMDOS) commands. Insert the disk to the first drive and type 'boot 1' to load DOS without autorun. Then just type ' save "prog" ' for saving basic program (it can be even empty) or ' save "screen" screen$ ' to save screen. You can type dir or dir1 to check what is on the disk. To delete a file use ' ERASE "name" '.
SirDavid wrote:Sorgelig wrote:I don't think so. You can't use mouse instead of cursor keys in every software. It doesn't work. When you can use both (like in the games I have mentioned), you can move cursor much faster using mouse than using cursor keys, so it can't be just mapped.

these simple commands i've already used. They work ok. But i need something more heavy for writing tests.
SirDavid wrote:I can't remember any program for now, but you can check it by saving very large code files, for example save "name" code 30000,400000. What do you mean by "more heavy"? maybe a loop would be heavy? Just an example:
for i=0 to 10: save over "name" code 30000+i,400000+i: next i
Sorgelig wrote:How can i be sure it was written correctly?
When i was adding write ability to BK0011M i had there good file manager similar to Norton Commander. Just press F5 and copy as many files as i want. Then run these programs to check if they are still working.
