Re: Sound Blaster 16 not playing nice with other audio devices

This is a ground loop caused issue, there's no good fix for it unfortunately... Balanced inputs will be able to help but all devices need to use them.

16MB ones I'd like to do but there's difficulties sourcing parts for them, these very large DRAM chips are uncommon and quite expensive but definitely not 77usd/pair expensive 🤣.

If you are in USA the 4MB 60ns sticks are pretty cheap to get but pretty much nobody sells them in EU and buying from USA will end up more than twice the cost due to ridiculously high shipping costs over there and import taxes that come on top aswell. They're not yet for sale but soon will be. …

For OPL3 ports move, try to make a new PnP EEPROM with OPL3 given ideal IO location you desire and acceptable IO locations that also don't contain 388. Hopefully Creative's utils respect the EEPROM settings. Windows definitely will.

You'll definitely want to use some of the older drivers, 4x.xx for example. The later ones are very buggy...

It does seem that there are a number of suspicious vias near the keyboard controller. You can see lot of corrosion on chip pins and also ISA slot pins aswell.

I have had no problems with any of my several SpecTek sticks. PQI I have had no issues with either, other brands i haven't seen or at least don't recall to.
Re: Strange problem with Trident TVGA8900CL

With a broken ISA slot side of things the video BIOS would be unreadable and the machine would beep with no video card error since BIOS checksum cannot be verified.

Looks like one of the lower address lines is not functioning on VRAM side of things.

I don't know the necessary sysexes to enable ADC related things, closest info I know is SW60XG related but how much applies to DB60XG I don't know : http://www.studio4all.de/htmle/frameset090.html

I had a similar issue that developed after some time and cleaning of the SD socket contacts fixed it.
Re: Lucky Star LS-486e rev F doesn't recognize ATAPI
Posted on 2019-08-10, 12:49
That won't make a difference unless the card has ins own BIOS and that BIOS knows what ATAPI devices are. I don't know any such card. But as said before, this won't matter, you load your favorite CD driver in DOS and get access to the drive, and even if BIOS did know CD drives, DOS wouldn't still …

None of my 486 (and older) boards know what a CD drive is, only my Pentium1 and newer boards do.

Capacitors can and do go bad and what you describe definitely sounds like they're at fault.

I am getting the freeze in DynaBlaster and haven't yet figured out the reason. SETUPSA definitely does something different but I'm not yet sure what. Running SETYMF after SETUPSA won't show improvement, at least suggesting that it isn't setting some secret stuff that I don't know about. I'll have to …

Re: What retro activity did you get up to today?
Posted on 2019-08-07, 16:49
I added a socket to my 386 so that I could use a 486DLC with it. While at it I heatsinked the 486DLC since it gets really hot without. It was quite PITA to remove solder from all the PGA area holes. Removal of the original CPU took maybe a minute. http://www.tmeeco.eu/BitShit/PCschit/SER0.jpg …

I would change the two "speed" jumpers and see if it makes a difference.
