nebula Posted June 21, 2006 Report Share Posted June 21, 2006 I have received a CORE and a SID module from another MIDIboxer who decided not to complete the project. I don't know whether it is tested or not.The CORE appears to be a CORE R2 from SmashTV. From everything I can gather, there is a mod required to make this work with MIOS 1.7 and above - or are there two mods required?The first is a jumper from J4 which presently goes to pin 21 of the PIC, it appears that I will need to connect that to pin 28? From looking at the module, I see pin 28 is already connected to a pin on J10 and J15. It looks like I can connect my jumper to one of those points rather easily, otherwise I'd have to desolder the IC socket. Am I on the right track, or is there an easier way for me to do this?Also, is there another jumper I'm supposed to relocate for connection to the SID module? TK mentions it in the MIOS changelog for V1.7, but it doesn't appear to be addressed on Smash's site. Quote Link to comment Share on other sites More sharing options...
TK. Posted June 21, 2006 Report Share Posted June 21, 2006 Hi,you only need to follow the instructions on these pages:http://www.ucapps.de/mbhp_core_old.htmlhttp://www.ucapps.de/mbhp_sid_old.htmlBest Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
nebula Posted June 21, 2006 Author Report Share Posted June 21, 2006 Hi Thorsten,Thanks, but the boards are already assembled, with the wire jumper going to pin 22. I'll change that to pin 28. Is that the only revision to the CORE I need to worry about? ... and I assume the only SID revisions are layout-related? Quote Link to comment Share on other sites More sharing options...
TK. Posted June 21, 2006 Report Share Posted June 21, 2006 I must say that I don't have a clear oversight over all the different versions and revisions. You could compare the layout with the schematic in order to find this out. You can also run the interconnection test to check the pinning if you are unsure.Best Regards, Thorsten.

smashtv Posted June 21, 2006 Report Share Posted June 21, 2006 Well, considering there was no R2 Core (just V2 or R3), you probably have a V2 Core.Docs for V2 are here.V2 was before the 1.7 hardware rev., R3 was after.Is the board green or brown?Also depending on which PIC it was built for it may have the wrong crystal.BestSmash Quote Link to comment Share on other sites More sharing options...
nebula Posted June 22, 2006 Author Report Share Posted June 22, 2006 Right!I guess I'm just making sure that the one jumper (moved from pin 22 to 28) is the only hardware rev required for MIOS 1.7 and beyond.You see, this page on ucapps.de sort of implies that there are two mods (bankstick connection and SID connection) - do I accomplish both of those by moving the one jumper?(BTW it's a brown board, so it must be V2. And it has a 10 MHz crystal). Quote Link to comment Share on other sites More sharing options...
