As for the mouse header - it has 5 pins,if that helps. I guess the 2nd pin going from left (my board does have it in place) is NC? It is actually in the same orientation as your picture and it goes up to the 5th pin.

I'll check. Visual inspection wise I noticed pin 1 goes to something that looks like either a ceramic cap or a ferrite bead.

Probably the best way is using a DMM and check pin 1 and then pin 5.

Speed wise, cache limit impact isn't that hard, as long as you have all drivers installed. I tested this with a 3.2GB Maxtor installing Windows 98 from HDD. It was pretty slow and I might attribute that mainly because it ran in the uncahched limit.

Gotta live with it though as the only 64MB stick I have is PC133, lmao.

I have also figured the fan pin headers. It's a kind of reversed 3pin header - normal fan are wired blk/red/yellow - this was not the case here. This board has it wired this way - red/blk/yellow. Took me a while to find out.

Another thing I was surprised to find is an ATX header, and right next to it, a DIP slot (much smaller than a BIOS chip) that is unused.

Thanks to keropi I've got this nice thing here in the mail:

You can expect a video reviewing it in the next week or so. Looking forward to hooking up my SC55 to it!

^ excellent , you are actually the first person this batch that confirms receipt 🤣
but as long as I don't get "hey this does not work" complaints I guess all is OK 🤣 🤣 🤣

any idea what soundcard is this? combo scsi2 controller + sound?

OOO! Scsi and sound on the same card? with an option for FDD also? Color me intrigued, I had no idea such a Frankenstein's monster even existed. it looks like an unholy cross between an Adaptec AHA_1542C and AD1848!

I knew sound blaster has a scsi/sound love child, but this one looks BOOTABLE, and has (potentially) FDD support.

Please excuse me while I start up some ebay saved searches for this!

The manual is still available online, it is an Adaptec AMM-1570. the 1572 has the FDD option.

If possible, I'd dump both roms and host on vogons drivers. Mostly the large sound-rom on the far left. For those that don't know, if you are dealing with ISA and SCSI in the same machine, the 1542C is THE card to get for such a combination.

Bought this pile of junk for 20€ shipped...:

Hope its not only junk but a memory card below it, which I can use to proove my concept here
ISA XMS/EMS Memory Extension / Expansion cards: Now Running without Driver / Documentation :-)

If yes, it was agood deal.

An IPC MediaMagic Telemetry-32 soundcard/modem.

Supposed to have onboard wavetable as well. And looking at it, I bet those two large ROM chips confirms it. Just have to wait for it to get here and find drivers.

Original price was $399 I think. from what I could find. Maybe $299.

Edit: Found the drivers.

Here are a few links that mention this card:
https://books.google.com/books?id=eMKimy4DFaE … etry-32&f=false - This one actually shows a breakdown of what it supports.

I guess these ROMs belong to the modem part...let us know 😉

since i' m too stupid to find this myself - what does the zilog do on the board? iirc a cpu of comparable power could not pull off midi in most cases;
and what is that intelligent midi thing? does it magically fix all intelligent mode troubles?

The whole board is just a specialized Micro controller. The Z80 processor was INCREDIBLY cheap and easy to use. It is right up there with the 6502 and 8051. Rather than make a custom micro chip, you could slap a z80 on a board with a bit of ram/rom and have it do all the work.

It is just a small cpu whose whole purpose in life is to watch the isa bus, take any data given to it, and translate that to midi signals. This was a VERY common thing to do. Quite a few early scsi cards did the same thing. including some top-shelf serial/parallel cards. Even some very early Ethernet cards have them. But that was short lived.

in this case this is a Z8 MCU , not a full Z80 cpu. It does stuff that it needs to do very quick and it's clocked at 12mhz.
The card is compatible 100% with the Roland "intelligent mode" functions, the firmware is just a port to the Z8 mcu from Roland's Hitachi (iirc) MCU so you don't need any drivers or other software to run the software that requires it

Today's prize is the Intel TC430HX motherboard with all the optional extras integrated:

• Intel 430HX chipset for Socket 7 processors
• Powerful S3 Virge DX integrated PCI graphics with 2MB of EDO memory
• Supports the latest Intel Pentium 233MHz MMX processor
• 512KB of L2 Cache integrated
• SRS 3D Yamaha OPL3-SA audio with OPL4 WaveTable
• The latest ATX format motherboard design with Universal Serial Bus ports

Installing Windows 98SE on this has been great - everything just works out of the box, all the drivers are already there and there's OPL3 or OPL4 options selectable for MIDI playback. The seller was selling it as broken, which it is if you plug the jumpers in like the picture, but it works when they're installed where the manual says they go 😁

I guess this would be good to pair with the Voodoo 1, but it's working pretty well with nothing plugged in as well (except when the processor gets busy the screen gets wavey because that's what happens when you put the IGP that far away from the port and run it past the cache chips)

Man that's a beauty of a board! Something about ATX socket 7 boards. Onboard OPL 3 & 4 and 3 isa slots!! That would be perfect for a mega sound card build!

wow that must have been an elite board or something back then, black ss7 mobo? 😮

With all the talk of Cyrix 5x86 CPUs lately, imagine my surprise when somebody stuck up this lot with a 5x86 120.

Also has an Intel 486 DX4 100 which I don't have yet as well as a TI 486DLC-33 and a Cyrix FasMath 40Mhz.

Initial asking price was too much so I put in an offer and it was accepted.. woohoo!

According to the BIOS string, it's a "1.00.xx.DH05 MBD001078 Millennia® LXA/ClientPro® MTA (Tucson P5/TC430HX)", which appears to be one of these:
https://books.google.co.uk/books?id=6TsEAAAAM … ge%20dx&f=false

So not particularly high end, but lucky that it has "integrated wavetable". Sadly, as I'm running it, it's getting less happy and more crashy, so I guess there are some issues to look into after all 😀

Maximum FSB will officially be 66MHz, and PCB colour meant nothing about the "eliteness" of an MB back then. As it's an Intel motherboard, it's likely closer to dark green anyway.

Found two sound cards on my list this past week: (sellers' photos)

Interwave based sound card:

And an Awe64 Gold hiding in this lot:

I can tell it was an incredible deal when you're buying them by the pound!

Not from yesterday but the weekend 😀

Got these 3 for 70€ which is pretty good imho.
The Olivetti has had some TLC scrub but due to keyboard error, I can't get it to post further. I think the HD is toast, it squeaks like an old wheel.
I have enough keyboards but this Olivetti doesn't seem to have a classic keyboard connector so any help is appreciated.
The seller also gave me the MS mouse that came with it but it has an parallel or serial adapter attached so I'm guessing the keyboard also needs something like that?
I need to find more info on the screen too. Not sure if it's VGA.

The Tandy should work according to a picture he sent me before but that is on the menu today. First one I've ever had....
Should I ask MS for the cellphone :p?

This also came in:

Not in the picture: an XT psu that has some damage to the switch so I need to look into that.

Traded this + Voodoo3 2000 for my boxed AWE64 Gold
