Re: Strange sticker on the processor. Pentium 166 MMX

Posted on Yesterday, 17:56

I have not seen this before, but it definitely appears what vstrakh described, protection to avoid shorting things with heatsink. I would leave it be, there's more than can go wrong than right when trying to remove it.

There is one thing that sticks out to me in this build, which is the power supply. Everything else looks to be pretty nice but the PSU is looking like one of those really cheap things... I do see the warranty sticker being broken so I guess it has new capacitors in it and probably will serve well. …

Unfortunately for me, all the Pro/100S I have go nuts with 50MHz (random freezes, unable to get IP and other oddities), but are completely fine at 40 and 33... But I don't think they are 66MHz capable either. I had some luck with RTL8169 but I never found a driver that works in Win95.

Do you know of a network card that won't mind 50MHz PCI speed ?

That is a strange problem, FM should be the one thing that shouldn't fight back... Laptops are special however as far as YMF71x card goes, allowing hardware specific configuration and you may have to use drivers that were originally provided with the laptop for things to work. Since SETYMF didn't …

the 9V written on the bricks is only under the load equalling to the current written on them, i.e at 1A or 1.2A. Without load it is normal to get around 14V range reading, that voltage will drop when actually connected to the synth etc. And as said before the devices these supplies are used for have …

You need something to push from the bottom edge of the cell to get one out, while holding that lever away.

It is definitely possible to get it up and running again but it will not likely be pretty since the copper is likely to be unsolderable without some effort and that may lead to some creative solutions to get the needed connectivities. These cards suffer from bad capacitors so they should all be …

The board seems to lack an onboard 14.31818MHz clock source and thus should rely on one from ISA slot, and it may not always be quite right although it should never be so wrong you have really noticable pitch difference... Do you have any other machine to test the card in ?

As far as EDID + Win9x goes, I found that I needed to use EDID 1.3 in my experiments, at least with ATI drivers. Version 1.4 didn't get picked up properly, with missing display name and other things.

That stable API is the OS driver interface (or things like Glide and ATI CIF), which unifies all the hardware for the software side of things. But all the stuff from driver to hardware is purely hardware specific and depends very much on how the particular hardware was implemented and there was a …

The acceleration is a non-trivial task, every different video chipset and chipset family has its own idea how things should work too so universality is not going to happen. The VBE/AF was basically not supported, and the rest is device/card specific drivers territory.

YMF701 - literally glued together OPL3, MPU401, SBpro2 and WSS. Non-PnP and resource hog since SB, WSS and MPU use 3x IRQs and WSS and SB use their own separate DMAs too. YMF711 / 718 - PnP, with shared IRQs and DMAs between all the components, dramatically reducing resource requirements. YMF715 / …

Yeah, it is usually not the transformer itself that makes the noise. Extra capacitance can definitely help a lot, and a good modern brick will fix the issue for sure.

Transformer laminations being loose can produce physical noise that won't be heard from the speaker cones themselves. You can listen if the transformer actually humms or even buzzes, which can also happen if a 220V transformer is ran at 230 or even 240V because the core experiences higher …
