Isn't this card technically an SB 1.5 clone; I believe we had established that the image used for the flash chip is the DSP from 1.5? or am I off completely? Just started building mine, so a bit curious..

Ok. Terratec EWS64 cards used Dream chips, and they had a free bank editor ( Ed!son ) available. Do Dream's current terms for some bizarre reason prohibit providing something like that to end user? Are you sure the Dream chipset was used for soundbank wavetables? EWS64 is a VERY complex card with a …

Yes, many - GUS came before AWE32, and was easier to support in software. See eg. the original Doom release: GUS supported natively, but AWE32 only works as a SB16. Native AWE32 was added later, in the Ultimate Doom. Yes but it was added nonetheless. Are there any high profile games that warrant …

Are there any games that support GUS but not AWE32 anyway? People seem to be really interested in this and I can't see why, GUS wavetable isn't THAT much better than the AWE wavetable.

Better use a fibreglass pen to expose a few millimeters of the trace where it is broken and join it using solder. This. Use flux and a tiny amount of solder on the iron's tip, this way you won't join traces together, and reseal it with uv curable mask. I just splash on some flux onto the area, tin …

Depends. If it's just VCC or GND, it will work fine. For traces carrying signals with high clock speeds however, a conductive pen is not good for fixing it. It will make the signal end up being distorted. Better use a fibreglass pen to expose a few millimeters of the trace where it is broken and …

ı've done some trace continuity checks on my 286 as part of my restoration project and found one trace that is indeed broken. The break is tiiiiny, almost microscopic, so I don't want to have to solder a botch wire between the legs of two ICs, one of which is PLCC so the wire has to be on the front …

By connection to KBC I meant ISA or dedicated peripheral bus, not connection between keyboard and KBC. CPU is not able to talk to the KBC so either KBC is damaged or connection to it.

Problem is most probably some connection to a KBC if another KBC won't work in there. If you can borrow one from another board then do so, if it still gives the same error you got a broken trace or a via somewhere. Pins 1-2-5 are definitely connected to the KBC, solid. If the circuit I posted above …

So it looks fine? Then I don’t know what else could possibly be wrong with this system if it does not boot when I replace the fuse other than a possibly faulty KBC.. The legs on it look dull so I’ll give it a spray of contact cleaner just in case but I guess adding a socket and replacing it is next …
