Thank's to TotO we know pretty precisely how the X-MEM works. Now let me ask a question: Which kind of software is Syx working on? Or is it secret?
SyX do a great work on the FW3.x !
Now, it's possible to use a simple CALL from the BASIC to program any ROM and we no more need to turn the hard switch ON/OFF on each programming. (it's use is more like a floppy disc now)
10 MEMORY &3FFF:LOAD"MYROM.ROM"
20 CALL &B8DD,&4000,1,256
(,256 is optional)Now, MYROM is written at ROM 1 using a 256bytes page.
10 MEMORY &3FFF:LOAD"BLANK.ROM"
20 FOR i = 1 TO 31
30 CALL &B8DD,&4000,i
40 NEXT i
The ROM Board is now cleaned. (sure, lazy blanking but more understandable)
Better to come...
