Re: SB2 clone (CT 1350) Sound Machine (project)

Hi, I got the PCB from you, populated it with components, but the card was dead as a doornail. The SB DSP autodetection wasn't working at all, the OPL2 couldn't be written to, and the analog audio path was broken. After a few hours (well?) spent, here are the much needed fixes. The first two missing …

Re: Finally! CMS Upgrade Equations for All SB2.0s

There must be some issue with your programmer, its settings or the chip type used. Programmer settings are OK (all other chips I program - like EPROMS - work fine). Only settings I can change for GAL are Programming voltage (set to 16V) and Encryption (I don't know if I should leave it enabled or …

try different GAL brand. Some programmers like Lattice more than NatSemi etc, some like National.. Often trying different brand helps! (sounds crazy, but its true) The ones I have are Lattice GAL16V8-15LP... Does it matter if it's -15LP or -20LNC or -25QB1 - because those are any other I can source …

Apparently when I will leave it checked - programmer will no longer be able to read from the GAL (for verification etc) - when I uncheck it - it will verify the chip with no problems. The old free equations should work with all card revisions. The only problem would be with the FM and the digital …

SirNickity, exactly. That's why I've put the equations into the public domain. In my equations, there is almost no room for further improvement, so why bother with licensing anyway? 😀

So does this mean that some hardware patching can be done to improve things? Yes, exactly! Toss all Sound Blasters into trash and make a new card design from scratch :D However, we still like them somehow... :lol: :lol: :lol: I was thinking something along the lines of un-grounding those SAA1099 …
