d2k Posted April 25, 2003 Report Posted April 25, 2003 I think the 6582A is the early 8580 version...they are the same i beleive.BestDan Quote
Jack Posted April 28, 2003 Author Report Posted April 28, 2003 Hello d2k!It the same! But not earlier. It was for a prototyp from a C65.Picture of the developer:@Monster SID Specs:- Classic SID Emulation (including address mirroring)- Monster SID Mode- 16 stereo SID voices (1-8 left, 9-16 right)- Sync and Ring Modulation and filtering on all voices- Extra voices mapped in order after the first three- DMA audio- 8 Stereo voices (4 left, 4 right)- 64k internal sound memory (sound or instruments) as well as access to main CPU memory for playing DMA clips- Variable sample playback rate- Audio resolution of 8 bits- DMA segment playback can be either continuous (loop) or one-shot (note/segment)- two sockets for classic SID chips, Monster SID audio can be routed through their analog filters (prpared for more analog audio routing)But which Chip ist the MonsterSID?wfgJack Quote
Jack Posted October 5, 2005 Author Report Posted October 5, 2005 It is time to learn VHDL!And develope the first MB_FPGA!For FPGA based Monstersid!wfgJack Quote
Davo Posted October 6, 2005 Report Posted October 6, 2005 Note that there are two sockets on the C1 for SIDs. I'd assume then that "Monster SID" means that the SIDs can be stacked as in the Midibox SID and/or used in a superpoly mode as the Midibox SID hopefully soon will be. Quote
tarzan boy Posted October 6, 2005 Report Posted October 6, 2005 i remember reading a while ago that indeed jeri (that woman) designed a new chip that was a monster sid; its not just a name for multiple sids inside the machine. I looked at the schematics of this about a year ago and i seem to remember the 'sid' that she designed being incorporated into the same ICs that control joystick input. She's also the person who designed the c64-direct-to-tv joystick gadget thing, which had all of the c64 recreated on one single IC. (it was even possible to hack the thing and add a keyboard, joystick, and disk drive to it) The reviews i read of that said that she 'faithfully' recreated the 6851 for this toy, although i don't know how connossierre the reviewers were in sid-dom. :) Quote
Jack Posted October 6, 2005 Author Report Posted October 6, 2005 FPGA based SID 6581.http://www.fpga.nl/jester.htmlwfgJack Quote
Davo Posted October 7, 2005 Report Posted October 7, 2005 Nifty! Anyone know if the sources to that are available? Can it be used as a drop-in replacement for a SID? Quote
