I can't but believe your willingness in participating in the "rom dump" game. Then you realize how difficult it is to actually dig out the case it is in and simply desist. Happened to me. :) I guess a lot of other people here. Do you have drivers, an old cd that came with it? or anyhting else? I …

Chipset: Cyrix Cx5510 (MediaGx) First version, last is 5530. Drivers are up to Win98. Can you dump the bios rom here? Sure, it appears the BIOS is a socketed DIP so that should be easy. It will take me a week or two though before I can get to it, but it's on my to-do list. It's currently in a case, …

Are MediaGX motherboards of much interest to the retro community? I have a GCT-MGX that would be considered a "new pull" with manual (this one https://theretroweb.com/motherboards/s/gct-mgx) It seems like a strange beast, AT form factor with integrated video and sound that come out on a card plugged …

Drove 45 minutes today to get this Macintosh SE/30. I was so relieved when I cracked it open and found an intact battery instead of an exploded mess. Needs cap repair but they pretty much all do at this point. Love it! I'm not an Apple person but still find them interesting. And was getting tired …

And feedback on eBay say nothing about this other than "great transaction blah blah". So weird. And 60 units were sold. I assume those buyers know how to make it works I would encourage the buyer to message the seller and ask about this. I've bought items from that buyer before and in my experience …

An update for anyone who might run across one of these and find this thread. The card works great, but the jumpers text file isn't completely accurate. They have some of the jumper positions swapped, specifically the IDE and floppy I/O address. So I'd encourage anyone who has one of these and trying …

Thank You to everyone (: I think I'm going to give up..... ? .... I'd be so curious and try controlling this manually. Only jumpers to ground or another pin is required. Although, if you've already connected a known good drive to the same cable, seems that should do the same thing. And feedback on …

Also, have you taken the top cover off to see if there's anything non-standard in there? I took the cover off. Looks very normal. Does it perform a seek at boot, provided that's enabled in BIOS? Older BIOSes did not have the ability to turn it off. Provided it does, another thing to try is format a …

Finally found the mini tower case I've been looking for. This is the exact same case that I had in high school for my am386DX-40 system. I just purchased this one on eBay and it looks to have an i486SX-25 CPU on a SIH 486B motherboard. There's a network card, IO card, video card, and modem …

Hot from the thrift store, the cheap bug bit me. $3.99.... the funny thing was, I was just thinking as I walked into the place "I dunno why I come to this one, no real computer parts in months, years..." I'm a little superstitious I guess, but it seems I never find something cool for dirt cheap if …

Bought this NIB Gigabyte Iram today, seems like a pretty cool way to use spare DDR to act as a SSD like device. Seller sates the battery seems fine but I will likely buy a new one for it as a spare, not sure if these can be recharged or not. (Yes they can be, says right on the battery doh) That's …

That's impressive. Did you have to pour white on all the black areas? I wouldn't know how else to do it. Irfanview -click I for picture information and check number of individual colors -reduce number of colors to that number -edit palette, in this case first color is black and just changing it to …

Yeah agree those are only if a BIOS is being used. Here are the reversed color schematics.. That's impressive. Did you have to pour white on all the black areas? I wouldn't know how else to do it.

From what I can gather, none of the missing chips are required for the card to work. or maybe U6 is required for address decoding ? U6 appears to be for address decoding, but only to read the set of jumpers on JP25 and JP26. I have not yet tried it on a motherboard, but will eventually. It looks …

Nice thanks. Ha there are two JP26 (the 8 pin header and the actual two pin jumper). Your pics are great but am used to white background for Schems so edited them to grey scale (probably not the best choices for palette)... might work on it a bit... Right, they have a JP26 in each SCH so it wasn't …

If you figure out where they go/what they do and post it here will add it (with your picture, the text, the datasheet, the schems) to our driver library with creds to you, PC Hoarder and a link to here for the work involved if that is ok. I think I have this figured out. First, I pieced together …

Oh cool, I was looking for a jumper reference. I found that same file but didn't know what it was because of its weird extension. I will certainly be studying this. Interesting though, neither schematic has JP25 or JP26, although the card and jumper reference has it. Time to trace some connections. …
