I bought 100 cardboard boxes that can fit any baby at/ATX motherboard and in there I put the motherboard in a antistatic bag and eventual accessories that can be used with the board (manual, vrm, coast module, I/O shield ...). IMG_20210410_230416__01.jpg Then I stick a label on the box stating …

The photo can bring informations the manual might not provide (such as the socket or the chipset sometimes). If clear enough it can even be used to help people with a damaged motherboard to fix their own.

I don't know, I've checked the jumpers, and also I've tried the landmark testing ROM and it didn't show any sign of life either.

Well I tried ... aaand failed. The board still doesn't give any sign of life. I might try to reflow it with hot air, but I think I'm about to throw the towel on this one.

You can edit presentations in UH19 without knowing programming at all (or even databases), we've got a dedicated form for that. Later I'd like to let anyone make an user account and use that form as well (with validation by admins for new users of course) Here's a page you've never seen yet (but …

I think the first thing to check are the ground pins. If you can find where they are, this should prevent you from blowing up anything (unless the game port has 5 and 12v outputs which I doubt)

Absolutely! (Even for just a 1MB simm)

PCChips isn't known for their quality. Maybe there's a cracked solder joint on both of your board's ? Mine didn't work properly until I reflowed the chipset slightly.

I have ordered 100 chips to fix my cache module so if you share the schematic I might produce some as well 😀

Type 47 isn't user defined ? Then I guess you'll either need another BIOS or you'll have to use XTIDE on a network card.

I here's my coast module which apparently hasn't been documented yet. It's a 01S3 stick but with Toshiba chips instead. IMG_20210405_163533__01.jpg IMG_20210405_163542__01.jpg There's something else I also noticed which hasn't been pointed by anyone yet it seems : 919 coast jumpers.jpg This looks …

Re: Gotek-like emulator drive for CDs?
Posted on 2021-04-04, 22:35
in theory could this not be done somewhat by making a CF card slot and simply writing the cd contents to a cf card? I get it wouldnt have the switching between multiple cd's thing but it's a start This would only solve the "booting from CD" problem. Emulating a CD-Rom is doable in software. However …

Something for IDE and with audio output would be really nice 😀 Perhaps using the bluepill board which uses a ST32 chip ?

Something that has to be done as well is to patch things so they're more accurate. At the moment, form factor aren't quite accurate (they didn't exist in TH99 so I tried to automatically add it ... Which worked for the most part but some board have a "unidentified" form factor, or a wrong one). Even …

I also tried with two 4MB sticks - the board wouldn´t start. I will test this board in the coming weeks. Although I´m not a big fan of ECS / Elitegroup (and never was) I kept some of the earlier boards like the "SI5PI AIO" socket 4 and the "SI54P-AIO" socket 5. The quality was absolutely o.k. at …

Other parts of the site that will use JS (if you prefer it) will work on any browser capable of AJAX (IE5 onwards). I have to say, it was pretty challenging to do that one, but I'm glad it works 😀
