Rave-TZ Posted November 13, 2010 Report Share Posted November 13, 2010 (edited) I have 8 SIDs installed, went with option B for the PSU since I'm using a C64 power supply. SIDs 1-6 are 6581s and its set to 12v while 7 and 8 are set to 9v for the 8580s. I hear a quiet high pitch tone with SIDs 1-4 but no tones from MIDI thru the SID. SIDs 5, 6 no tone, no sound. 7 and 8 work fine. SIDs 1-6 get very warm, almost hot to touch. 7 and 8 just stay warm, not hot (guessing due to 9v VS 12v). All cores are responding to MIOS Studio. Any ideas what I can try? Very new to this. Edited November 14, 2010 by Rave-TZ Quote Link to comment Share on other sites More sharing options...
Hawkeye Posted November 13, 2010 Report Share Posted November 13, 2010 Have you measured voltages without SIDs plugged in, as described in TKs build document? If so, you could move the 8580s to 1 and 2 (set to 9v before!) etc and test the output circuits. It is normal that 6581s get warmer than 8580s. You can add passive heatsinks (see my photo tut for parts link) if you feel uncomfortable about it. Quote Link to comment Share on other sites More sharing options...
Rave-TZ Posted November 13, 2010 Author Report Share Posted November 13, 2010 Voltages all check out. Will swap the 6581s with my 8580 here in a sec Quote Link to comment Share on other sites More sharing options...
Rave-TZ Posted November 13, 2010 Author Report Share Posted November 13, 2010 MIOS Studio has a difficult time connecting to core 1 when the 8580 is connected. I made sure to set to 9v. When I removed all the SID chips the core was easy to connect to. I only get the high pitch when I upload setup-mb6582.hex. This is really confusing me.

Rave-TZ Posted November 13, 2010 Author Report Share Posted November 13, 2010 Am I missing an important Master/Slave core setup procedure or something? Quote Link to comment Share on other sites More sharing options...
Rave-TZ Posted November 13, 2010 Author Report Share Posted November 13, 2010 All sid sockets test tone perfectly (1-8) Ouch, my ears. Quote Link to comment Share on other sites More sharing options...
Hawkeye Posted November 13, 2010 Report Share Posted November 13, 2010 did you try with fewer sid chips, maybe a psu problem when fully loaded? try with two 6581 in 1 and 2... Quote Link to comment Share on other sites More sharing options...
Rave-TZ Posted November 13, 2010 Author Report Share Posted November 13, 2010 did you try with fewer sid chips, maybe a psu problem when fully loaded? try with two 6581 in 1 and 2... Still no notes. Im using the virtual keyboard in MIOS Studio. Ch1 produces notes on sid 7,8 before I pulled them. Retested voltage, test tones. All check out. Can I get a quick bullet point procedure list on uploading? I've uploade MIOS v1.9g for PIC 18F4685 to core 1 (although I believe the cores already had this due to the sticker on them saying "BSL V1.2b MIOS v1.9g") I then uploaded setup_mb6582.hex to each core. The cores are installed in the correct device id order (0-3) Is there any other apps I could test core 1 with? Maybe an asid player? Kinda blind without a control surface.

Rave-TZ Posted November 13, 2010 Author Report Share Posted November 13, 2010 Core 4 works great, its just 1-3 Quote Link to comment Share on other sites More sharing options...
Hawkeye Posted November 14, 2010 Report Share Posted November 14, 2010 (edited) random mental output: * Do the 6581s now work in core 4/sid 7+8? * I don´t know how the 6581s behave, but have you jumpered the audio in headers, so that the sid audio in pin is grounded - on the 8580 i get some static noise or 50hz hum if left open, but not as extreme as you mentioned. * Are your cores installed in the correct order - 0 right ... 3 left? * Have you uploaded the same (newest version) of mb6582.hex to each core in mios studio, setting the midi jumper on the baseboard and the address in mios studio so that the right core receives midi data?

JRock Posted November 14, 2010 Report Share Posted November 14, 2010 (edited) Yeah. I was gonna ask about jumper J11. I guess you have that under control if you uploaded MB6582 to all the cores... Here's a Java Based Virtual editor: SID Editor V2 What happens if you take all the PICs out besides 1?

Rave-TZ Posted November 14, 2010 Author Report Share Posted November 14, 2010 (edited) 6581s work on slots 7 and 8. Test tone works on all 8 slots without sids and with on 7 / 8. Removing all cores but 1 produces no difference. Swapped 585s and caps with core 4 to 1, no effect, tried another c64 psu, no go. Checked for bridges, nothing. Voltage on cores check out. mbsid ver 1.9g updated, cores in correct order Edited November 14, 2010 by Rave-TZ Quote Link to comment Share on other sites More sharing options...
Rave-TZ Posted November 14, 2010 Author Report Share Posted November 14, 2010 issue solved, some 595s(74HC595) where mixed up where the 165s(74HC165) go. Once sorted everything works. Quote Link to comment Share on other sites More sharing options...
