Re: Voodoo 2 component map

Posted on 2024-03-16, 21:20

Instead of creating a new thread, I need assistance finding out two capacitors C50 & C81 on the STB Voodoo2 cards. I can't find an equivalent component map. I need help reading the values and packaging to get the right SMD capacitors. Thanks. Both of those are 10uF 16V. In fact, all the SMD …

@smsdave, That XT-IDE will do the trick :) I took out the two positive pins and soldered a wire to one of the vias... the negative pin solder directly into the farthest of the two points on the Mega PC mainboard, on a slight angle like I have. Put some tape under to avoid shorts. Then solder the …

@smsdave, the CR2032 is removable so if I decide to ever put my Mega PC in storage i'll just take it out. The diode protects it from being charged whilst running so no danger there either. I had to modify the adapter from Amigakit.com and add a wire to make it fit. Its a nice solution overall, i'd …

I've been working quite a bit on my Mega PC the last few weeks trying to repair the damage to my board and get my floppy drive working.. Here's what I found under the Floppy header 20201201_124159.jpg After some cleaning I managed to trace all tracks and repair 3 broken VIA's with small pieces of …

Ok :) I've scanned the Techinical Manual but realised its too big to attach here (Its 18MB, limit is 5MB). I can do the other two in the coming days.. just wondering how I can get them on here... @Dioxaz, Would you like to add them to your archive? @Zalog, Wow! That looks brill! I have an X5 but …

I'm looking at putting one of those CR2032 adapters from Amiga kit in with the diode to stop the charge circuit.. The "Technical reference" looks just like a regular Mainboard setup user manual. No schematics or anything.. Here's some pages to show you.. Filename 20201123_214421.jpg File size 1.48 …

I finally have my Mega PC! I've stripped it down and checked everything. The battery has caused mild damage which has taken out the funtionality of the floppy drive, but the HDD works perfectly and is still loaded with the stock software! I will take off the floppy and HDD headers and check all …

That means its worse than a 486sx25.. but still a little better than the 386sx25... ok benchmark it just for a laugh 😁 Edit:- what about X-Wing?... Edit 2:- does the 486 aware BIOS recognise HDD above 500MB? And allow booting from CD?

@smsdave I have tried to find a clip on solution too but had no luck... so started to think how I could make my own with one of those Ti 486SXLC G50 CPUs. I can't seem to find the 100 pin QFP clip on sockets now either so maybe its going to take some time to figure out what to do, if anything at all …
