A bit of thread necromancy here to resolve the issue possibly: The ASUS website says you need BIOS 1007.A or later to resolve specifically an issue with the K6-2 500MHz chip. Additionally, the K6+ compatibility page says that the version 1.05 and 1.06 boards are slow with K6+ CPUs due to a hardware …

The only card plugged in at the moment is the Voodoo 3, along with a Gotek drive and a CF-IDE adapter. Loads more things to put into the system, but I figured it was best to test each component in turn.

Probably not going to attempt anything with hardware--I am having too much trouble just getting something that will POST and boot. 🙁 This is rapidly becoming a very expensive project.

I just received an EFA Viking 3, my second super socket 7 board. It doesn't recognize the K6-2+ CPU without a BIOS update which has not been installed yet. The video card comes up, the board tests the memory, etc, and then hangs here: http://i.imgur.com/qp6SZR4m.jpg The CPU is a K6-2+ 550, but at …

The other thing I suppose I could do which might make more sense than trying to make the turbo function of a SS7 board be useful for something might be to swap out the SPDT turbo switch for a DPDT switch. DPDT could be connected to the FSB jumpers to select 66MHz or 100MHz. I'd probably want a …

I recall that in the later socket 5/7 days, boards began featuring a turbo LED connector, but often lacking a turbo switch connector. Take for example this EFA Viking 3 . If you llook at page 8 of that manual, the front panel connector lists a turbo switch connection. Next to that is a pair of …

Either you run your output of one to the input of the other, or you use an audio switch like they use to test speakers in stores, or you run it to a mixer. Mixer is most flexible setup. Something like the Rolls Mini-Mix II stereo would be perfect for the purpose--it's just inputs and separate volume …

I recently picked up AT case that used to have rubber pads that held the motherboard in place and stopped it flexing in situ, however they had …

Pictures I can do! Here's the back side of the plate. As you can see, there's NOT much to work with here as every single hole on the motherboard has a standoff in it, they're just all plastic keyhole types. If you look at the bottom edge of the picture , you may have spotted the board edge standoff …

For my budget SS7 box, I ended up using an AT/ATX hybrid motherboard because it's a lot cheaper than any SS7 ATX board I found. I decided to spend a little more than the price of a budget ATX case and buy an cheap AT case which I figured would be significantly better made than what passes for cheap …

On the Apple IIgs, we use 3.6v barrel batteries. In the case of the original design, these are soldered on as I recall them being on many 386 boards. The ROM3 machines have a battery holder. And it turns out the battery holder fits the holes for the soldered battery, so if you have room, that's an …

Hey everyone, I am building a super socket 7 system on a budget and picked up an Acorp 5ali61. It has a turbo switch connector, but the only manual I can find for it gives no indication what turbo is going to do for me. Classically, I know that when a turbo button was pressed, the system would slow …

I personally chose the Yamaha card because it's so quiet compared with the average Creative Labs card, and it's got the real OPL chip.

I'm hoping that once the prototypes are all built/tested, perhaps these can be sold fabricated rather than as kits. That'd probably mean a switch to SMT parts and a new board layout, but at least it'd e established that the design works by then. I can't solder a board like this to save my life (with …

Hey all, Possibly thanks to Phil's videos on Super Socket 7 (thanks a lot Phil! ;) ), the prices on Socket 7 have become kind of crazy since they can throttle all the way down to support 386 DOS games, but up to handle pretty much the end of DOS gaming. Can the Athlon XP-M boards perform a similar …

My understanding of this (for folks who are joining late and haven't skimmed through 13 pages) is that this is an effort to create an ISA card compatible with the real Roland MPU-401 interface, including with the intelligent mode needed by some games to use with the MT-32 and other such devices.
