Replace all the caps. Antec (in my experience) has good power supply design and absolutely terrible cap selection.

Any concerns about the surface mount caps?

Following this for sure. You could consider some black screws/washers for that top to streamline the look a bit. I suppose you could also sand and paint or create a sticker friendly plastic or acrylic shell for it. I never really do much in terms of case customization, but it does have quite the …

Yo Ace! I can't answer regarding the difference between the SB16/MX300 and the YMF719 cards' wavetable header, but it is rather interesting - the external CHiLL MIDI interface board available on serdashop basically jumpers to select if the L and R output go straight through, through one 47k resistor …

Funny thing about caps is that the printed stuff like voltage, uF, and temperature have good wiggle room while the unprinted stuff like ESR and ripple are a little more important (imho).

Hmm. Not sure the full reason, but I moved it back over to the 386 from the Pentium and it works. Zeroed out Precomp and Landing Zone. Also - DOOM 2 on a 386DX-33. Wow.

Seems to work OK with a 250 MB Normal drive. I just assumed ontrack caused the problem, but I can’t initialize it with the Win 10 pc.

Dude. So much case work and certainly lots of dedication. If you need any encouragement, you've got it. Also! ... You could always stick with that mobo and solder in a VLB socket - be it with this project or some other one.

Found this in a thrift store today. Sound Blaster 2.0 box with I think everything. Too bad it didn't have the card in it. box_front.jpg Wow, cyclone3d. Nice pickup. How long did the old sound blaster last after the box redesign? Its days had to be pretty numbered by the time they moved to the blue …

I found it odd that it would have the correct custom specs still in "user defined 1." That said - I've got a replacement battery case with 3xAAA and a wire, so I'll add that to the equation just to eliminate another variable. Perhaps a different HDD type is best anyway since the drive is using …

Well the P90 saw it. It does have an ontrack overlay. chkdsk causes extremely weird things to happen. Otherwise, DOS, Windows 3.1, DOOM2 with some savegames. Fun stuff. Latest files on there appear to be from 1998. Looks like it was rebuilt/repurposed in 1995 - and apparently for college. Not sure …

Hey guys - Picked up a 386 system a couple of years ago. RAM issue. Finally toook care of that and got it up and running today. I am having some issues with the hard drive (HD controller failure message from the 1991 386 BIOS, etc) - a Western Digital Caviar 2120. The no-battery mobo still has the …

Different jumper configurations for SX vs DX on a 486 is pretty normal stuff. I just assumed it was chipset related.

There is a bit of a grey cloud representing the phrase "it works" for a given PSU. There could be a noisy PSU that meets the power draw requirements and the components seem to handle everything OK. There could also be a rather barebones PSU that works and has no protection inside. There could be a …
