Jupiter ACE - SDOS
azesmbog:
well closed - so closed.
SDOS - open specification by the author of PVV
And here I finish the game, especially as it is offtopic.
A couple of photos from the screen and that's it. SD card is real.
Someday I will please the owners of the ZX UNO with one more, “correct” core
KWF:
Good work.
Could you share your game? Is it TETRIS clone?
azesmbog:
No, this is not my game, this is a standard game for JA

There are sources for it, you can try to change the control to other keys.
The game is good, but at level 10 is already very high speed.
Just this game first earned in the emulator, they trained on it :)
Now others are running, not all, but with a dozen checked - work.
I would like to check this demo

but he is nowhere?))
and yes, SDOS supports subdirectories and the CD command and TAP files
KWF:
azesmbog: So sorry for being picky, but how the SDOS is in relation to the Jupiter ACE hardware. Is there any release available as a ROM image that we could burn into EPROMs and give a go in the hardware? What is the port used for SD card operations?
Don't take me wrong, I appreciate SDOS team work, but if you could share more detailed information I would be grateful.
azesmbog:
SDOS can be configured completely to any addresses, in this case the ROM is located from the address F000h, the size is 2391 bytes.
In the 2kB version, you can probably do it.
In the more complete version (for example, under Galaxia) there is a pause in the output of DIR and the recording of files is implemented, but the size is slightly larger, but still within 4kB
The SD sector buffer is 2kB from the E800h-EFFFh address, possibly also from any address, at least in the main memory.
Well, you also need two ports or memory cells, in this case, cells E000h and E001h are used for the operation of the SD interface itself. Cells can also be selected arbitrarily, perhaps even you can use FFFEh and FFFFh if you wish so much)
The SD interface itself can be assembled at least on logical chips, either on CPLD, for example EPM7064SLC.
Summarizing, if it works in FPGA, then absolutely there should not be contraindications for working with real iron. Only desire and free time :)
