sweet! I am assuming the serial and audio just go direct to pins on the db62 the monitor I think probably passes some signals from one connector to the other but both sets of sync and color singals go back to the card for the small relays to switch I think Looking forward to the pinout thank you …

Socket 5/7/SS7 really was an amazing platform we will likely never see again. It spanned 75mhz to 570mhz (though 10mhz to 700mhz is possible ) 50-100mhz fsb (some supported 7mhz, even 150 mhz though never stable) 1.6v to 3.6v Multipliers spanning 1x-6x Cyrix, ST, IBM, Rise, intel, AMD, IDT, and even …

Very nice! Isn’t there a thread around here for how to do that? Did you document the process?

Settings are stored in the RTC I believe.. but some bioses I think had the ability to rewrite themselves, there is a thread around here about one that kept corrupting its self during that if I recall. Anyway, battery! Sweet!!! Great job dude! Yeah, definitely wanna remove that 5v power source. …

If I'm reading the database correctly, one of these may work. 82C493.zip when I get it back, or if Tony wants to continue tinkering with it, next up is to: - install a AnyCLK in the place of that crystal - install a pod83, or a amd 133 on interposer - see if ram maxes out at 32 or 128 mb - see if it …

update! Tony359 got the board repaired, post, and even got the cache chips I sent working! he's going to play with the battery and see if it can take a coin cell. one thing left that I think would be cool is a Mr Bios for it. anyone familiar with the Mr bios collection enough to suggest one to try? …

Looks like it supports 4mb of memory, swapping out those memory chips should be easy enough. If the address lines are there, and they come in 2mb http://www.bitsavers.org/components/s3/DB018-A_Trio64V+_Integrated_Graphics_Video_Accelerator_Jul95.pdf If someone with a PC can rehost that pdf here that …

At this point I think I am basically dead in the water on this project. Without the cord this is nothing more than a curious brick. If anyone can help mapping the pinout of the cord, that would open up some possibilities. If anyone has a cord, that would be even better, I kind of expect that I am …

I did some more investigating today. Turns out the unit is indeed a dual plane socket. The regulator at the back seems to step 3.3v (which I assume comes from the pci slot) down to 2.8v Again, don’t see any jumpers to change it, The two planes in the socket are indeed separated verified with ohm …

https://en.m.wikipedia.org/wiki/List_of_VIA_chipsets According to this, The chipset supports 512mb of ram. So if they ran the address lines for it, It may actually max out at 256 or 512mb I’m going to guess probably not 512mb with only a single socket though. Probably 128 or 256 is where I’ll end up …

The model I have seems to only have jumper settings listing up to 200 mhz As we know though, the 1.5x and 2x can be handy for later processors. However there seems to be a total lack of voltage options on the board. Leading me to think that my particular one might be single plane. Peeling the …
