Had to travel a bit today, but I think it's worth it. First, another AT desktop case for my 5x86 VLB machine:
The size and internal layout is almost identical to another case I have:
Although this one has a much more interesting design. You can't really see it, but the case has both a Turbo button and a LED display (it's inside the black area). Sadly, it has a crack on the side of the front panel that isn't visible but is on the verge of breaking off. Not sure if there's a way to fix that kind of plastic.
Inside is actually a full system:
- an IBM 6x86 150+ CPU.
I don't really "collect" stuff, but I think it's fun to have this. I also have an AMD K5-100, so it's not going to be a lone weird Pentium clone in my closet! Seems like the system is configured to run this CPU at 188 MHz when Turbo is on.
- an ASUS P/I-P55SP3AV motherboard (the photo isn't mine):
It's my first Socket 7 motherboard that doesn't use an Intel chipset but rather a SIS510X one. It has onboard SIS 6205 video and ESS1788 audio. The connectors are placed on a peculiar addon AV card that uses a proprietary slot and even has Waveblaster header. I also think it's interesting because it has both a COAST slot and slots for 486-like cache DIP chips.
Finally, got this Socket 3 motherboard:
Can't identify this yet: it just says "AV-7541 rev 1.2" on the front (Google tells me that the vendor could be "Ansoon Tech Co", but that's it). It's SIS471, ZIF socket, 3xVLB, has VRM. So I guess, it should support my AMD 5x86. Kind of hoping it supports EDO RAM or is at least less picky about FPM sticks than my other SIS471.
Interestingly, it has jumper settings for 1M of cache. I can use my other SIS471 board's chips as a donor, but it only has 256K.
Also, it's missing a battery. Looking at this layout I assume I can just ask my friend to desolder a CR2032 holder from one of my other boards and just solder it here, right?
