Ixox Posted February 24, 2016 Report Share Posted February 24, 2016 (edited) Hi, I'm trying to come up with a PCB for the minimal surface Core8 based SID V1. I have a hand-wired proto with one 24LC512. I modified the setup_8580.asm file with "#define DEFAULT_BS_TYPE 1" and recompiled the firmware. It works fine, the 24LC512 can save 2 banks (A & B). On the PCB i have some free space and i wanted to add a second DIP8 for a second 24LC512. I'd like the second 24LC512 to store bank C & D. My question is : must it be wired as the A=1 or A=2 24LC256 based one this shema:http://www.ucapps.de/mbhp/mbhp_multi_bankstick.pdf Thanks, Xavier Edited February 24, 2016 by Ixox Quote Link to comment Share on other sites More sharing options...
TK. Posted February 29, 2016 Report Share Posted February 29, 2016 Hi Xavier, interesting that somebody still builds a MBSID V1 :) For the DEFAULT_BS_TYPE == 1 configuration, address selections A0, A1, A2 and A3 are used. A4-A7 are not addressed. Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Ixox Posted February 29, 2016 Author Report Share Posted February 29, 2016 (edited) Hi Thorsten, Thanks for the reply. Yes i've found a populated core and SID V1 boards that were useless in a box for a long time. I'll try to put the synth in a 19" 1U Rack with the simple CS. But after i posted my message, i've ordered an other SID PCB, a 8580 and a PIC18F4685 to turn my old midibox V1 into a stereo V2 :) Best, Xavier Edited February 29, 2016 by Ixox Quote Link to comment Share on other sites More sharing options...
