Nice p66 gold top. I really wanted a p66 back in 1993.

Weren't those CPUs expensive in the early 90's?

X3 AOpen AP5T boards the small one seems a little different, i love that brand, they seem very well made for a Chinese boards, but i guess there was some good ones among the most China junk.

That site claims that boards support AMD K6-III will be interesting to know if its true will be great. But if i can recall correctly as K6-III was AMD only, should not run on intel chipset, but who knows...
http://www.interloper.com/products/product-de … =100377&cat=399

An working 8086 8 bit board, with Fujitsu clone, i guess the ISA cards are working as well. A pair of x2 32MB EDO memory and Kingston ones most strange thing they are from USA...

X2 ISA IDE HDD controllers, as i did not have a single one, now i will be able to finish my 386 build with 450MB Seagate ST3491A HDD...

All things are working except the 386 AMD DX mobo (in the middle with the sooldered CPU), that don`t seems to turn screen on.........

All for 35 euros

K6, K6-2, K6-III, K6-2+ and K6-III+ can pretty much be used on any socket 7 board. They are very compatible.

Of course there are some exceptions, but more likely than not, it will work just fine. And yes, I have tested K6-III+ and K6-2 on older Intel based socket 7 boards.

AOpen is/was a good brand.

Well at least you know how to run K6-II, K6-III to only socket 7 boards (not S socket 7) so i will like to know how to run K6-III on one of these AOpen boards, when i got that CPU.
So far i did test K6-II 450MHz and did run only on 370MHz, as that is the max system bus, not 100, also the multiplier max is 4.5, so i guess only way to run that or some K6-III on that type of boards is overclocking, or some BIOS mod..

Yeah AOpen feels premium, not much of the brands back then did feel so nice, and they are still alive, but seems they are not in the hardware manufacturing anymore......

Just a correction to what Cyclone said:

For socket 7 boards and CPUs, pay attention to the required CPU voltages. Some boards can only run Pentium, Cyrix, K5, and earlier K6 CPUs as the onboard regulator only supplies ~3.3V. Boards that support the P55C (Pentium MMX) CPU often have a regulator flexible enough to run later AMD SS7 CPUs as well.

Earlier boards can be made to work, but it requires items such as socket interposers with onboard voltage regulation.

This is correct. I should have mentioned the voltage requirement. The boards that support MMX are dual voltage. One voltage for I/O and one for CPU core.

Some Socket 7 and even Super Socket 7 boards do not list 2.0v which is the default voltage for some of the K6-2+ and K6-3+ CPUS. However, they do list a 2.1v with one jumper installed. If you look at the way the voltages are set, that single jumper is .1v, so if you remove it or turn it off, then you have 2.0v. 2.1v is fine to use as well and won't hurt the CPUs, and may even be needed for stability on some boards.

I've bought an XCESS S7-MVP3 Socket7 board with a K6-2 380MHz. Wonder if it's any good?
It looks like this: https://www.ebay.com/itm/XCESS-S7-MVP3-REV1-2 … d-/380340162889
It came with original box and manual.

The star of the show was this Hercules 3D Prophet 9700 128MB:

So far nothing ratio is set to 2, voltage is set to 2.0 with removed jumper, the bus is set to 83, no post screen at all..
That board support MMX pentiums, but does not have x2 voltages the hell..
The other AOpen AP5TC does have second voltage 3.3, but does not have 2.1 or 2.0 vcore voltage, maybe if i set 1.8 vcore...
Really strange one of the boards does not have the I/O voltage, but have 2.1 vcore, the other one, have 2.1 vcore but lack I/O voltage, and they both seems to support MMX pentium...

Edit

Did not look the K6 want 2.2v vcore, as someone say they need 2.1v or whatever..
Well now it did boot up on 2.1 vcore, but only at 333MHz on 83Mhz bus...

Edit 2

Seems the AP5TC was able to run the K6-II even at 500MHz, now only thing is need to compensate the lack of 100MHz bus on the mobo 83 is the max, and there is no overclocking in the bios.
Also is there a way to run the K6 on 550, so far seems not, as i tested the other ratios.
Maybe if i put SDram 133MHz this will end up as 110MHz memory and that will work just fine..

If you can identify the VRM chip, the required jumper settings are often available on the datasheet.

Got the industrial system from my post back a few pages.

I was wrong on both the backplane and the installed SBC.

The SBC is actually a Socket 478 Pentium 4. Model number SBC 81822 with ISA support. Chipset is Intel 845GV 😀
http://www.orbitmicro.com/download/resources/ … 1822_Manual.pdf

I can disable the onboard video.
It also has built in AC-97 audio... which is kind of surprising but useless for my purposes.

The backplane is a PX-14S of which I can't seem to find any documentation about. Not sure if I can install 2 SBCs at the same time or not.
Picture I ripped off of eBay:

Currently working on backing up all interesting files and then I will do a clean install on different HDD.. or maybe I'll use one of my IDE to SATA adapters and throw an SSD in there.

I wonder if speed sensitive ISA sound cards will have issues with this setup or if the industrial stuff is much better at keeping timings proper for what older ISA cards expect.

How much does disabling the L1/L2 cache on a S478 P4 slow it down?

I ordered a CompactFlash to 2.5" 44-pin IDE adapter on Amazon today. It'll go into my Powerbook G3 (Wallstreet) laptop once I get a Transcend 8GB (or failing that, 4GB) CompactFlash card for it soon. I'm really looking forward to getting a CF SSD into that laptop so I have another IDE laptop hard drive to spare for experiments.

500MHz (6x 83MHz) will be the maximum possible. 83MHz FSB is already 'overclocking' for this chipset, the maximum officialy supported FSB is 66MHz.

The 133MHz SDRAM will run at 83MHz, the 133 is only the maximum speed rating.

If this runs stable, it's quite a nice system! Some PCI cards might have trouble with the overclocked PCI bus.

Well if you can see it here, as i don`t know with chip is the VRM controller

Well then i guess i will need other mobo for better results, as for this one K6-III will be ok, just to find one on cheap.
The Video will be S3 Virge/DX, or other depend what will work on that bus.

Yes, you would be looking for a Super Socket 7 motherboard. Phil did a video on this: https://www.youtube.com/watch?v=0K_w_st8wn0

K6-III CPUs run fine on my Tyan S1573S although max FSB is 83MHz, but they work fine at 66MHz FSB at up to 400MHz speed.

That GUS PNP card. Wait... is that chip from AMD? I didn't know that AMD made sound card processors/chipsets. Also, love the MT-32 and MPU-IPC card as well. Kudos!

thx. yes... the interwave is from amd. it is a great card, but at the scene demos you can have some gus compatibility issues with the timing.
