luke Posted April 27, 2010 Report Share Posted April 27, 2010 Hi all! Here's my version of the SID-Board. It's based on two 8580, compatible to the Core32 board and the drivers found in the repository. Chip select is on J5A, but can be anywhere else. It only needs a +5V supply, the 9V are generated on board. Also there are output amplifiers to attennuate the signals to a 1Vpp level, line-out compatible. The board is 80x50mm, two layer. I am currently doing a redesign with two 6581 and two 8580 SIDs. More details soon. Questions, Ideas etc. are welcome.MBHP_SID_V4.pdfMBHP_SID_V4_brd.pdf Quote Link to comment Share on other sites More sharing options...
luke Posted June 11, 2010 Author Report Share Posted June 11, 2010 (edited) Update: inofficial MBHP_SID_V4.1 features: -supports two MOS8580 and -swinsid x2 compatible (this is not my brainchild, i solely announce the compatibility. i do not provide the firmware, as this is swinkels' work) -makes a total of 4 channels -logic chips replaced with an altera max7000 cpld to provide greater flexibility -only requires 5V supply, as the 9V are generated on board connectors: 4 x SMA (or SMB), one per channel 1 x 2pin external 5V J5a and J19 for link to MBHP_CORE_32 J5a: -/CS0 and /CS1: binary chip selects, that get decoded by the cpld -EN: global enable -SPARE: not in use yet J19: -SCLK, RCLK, SO, SI (standard, si not yet used, might be handy in future for things like reading out sid registers) Status: Two PCBs have been produced, one of them has all components placed. The CPLD-design is still beta, but will be stable before too long (this is caused by size difficulties, maybe a bigger cpld in future versions) Edit: IC6 / Pin3 must be on VCC for reliable operation. This corection is the blue wire on the bottom side of the pcb.

Smithy Posted June 13, 2010 Report Share Posted June 13, 2010 (edited) That looks pretty cool Luke! Nice and compact 4 x sid(V-sid) beast! Not sure how i missed this first time round. Edited June 13, 2010 by Smithy Quote Link to comment Share on other sites More sharing options...
luke Posted June 22, 2010 Author Report Share Posted June 22, 2010 thanks! i am still working on the cpld part, trying to find a way to easily provide reading access, but updates will follow! Quote Link to comment Share on other sites More sharing options...

Hi, luke In the your MBHP_SID_V4.pdf file the 74HC595 SRs outs are connected to diferent pins of Sids, than I can saw in the Sid module and in the fnp-sid ( stereo sid ) schems. The first SR in this chain controls a data bus instead of addreses and the second SR controls a address bus instead of data. Is that realy workable without any software changes? sorry, may be I am wrong. Regards, Janis Edited July 22, 2010 by Janis1279 Quote Link to comment Share on other sites More sharing options...
