Can anyone find or get a copy of the internal ROM from the SPO256AL2? I want to emulate it - Executioner 12:39, 1 September 2006 (CEST)
- Hmmm... I can probably manage that, i got the chip! But how to read out the ROM data? Can a simple program on the CPC do that or do i have to plug it in a romboard to read the data? (Have to check the pin configs i guess) --CPCLER 12:52, 1 September 2006 (CEST)
- Is it an additional CPC OS rom? If yes, it's quite easy, I can send you a program for this. BTW, @CPCLER, please use the colon (:) at the beginning of your "talk"-text for correct formatting. -- Prodatron 13:46, 1 September 2006 (CEST)
- (Sorry about the colons!!! New to this wiki stuff) No... I have uploaded some pictures of the SPO256 board, and there are clearly no additional ROM chips! so how to proceed, any way of reading the rom data via the SPO256 chip?
- The software for the SSA1 has to be loaded from disc or tape (I will test this when i get a CPC up and running). I think the dk'tronics (also based on the SPO256) had at least the software on rom, dont know if it actually used the feature with a rom connected directly to the SPO256.
SPO256 internal phoneme ROM
- No, this isn't a ROM for the CPC, it's the built-in phoneme ROM in the SPO256AL2, and it can only be read by using the serial output on the chip itself, which will require some hardware knowledge and the SPO datasheet. Yes, I do also have an SPO256 in my SSA-1, but no way to read it... Guess I'll have to desolder and pull the chip and connect it to my 8255 I/O board (no idea if that still works) :)
