Intel Pentium 120 SY033 - the last p54c core, 0.6 micron, officially socket 5
Micron 72 pin EDO 60ns 8M x2 - period correct size

Diamond Stealth 64 2001 2M PCI ARK Logic ARK2000PV - it would be really great, very good dos performer (~et6000, riva128 in 1995!), and decent output quality, but i did not find anything about it before aug 1995 - out of my strict period

Diamond Stealth 64 DRAM 2M PCI S3 Trio64 - perfect period match, but the output is too dark, the dos performance is also below the millennium
Fastest video card for DOS, Socket 3 VLB / Socket 5 / Socket 7 / Slot 1 FPS comparison

Since that GUS isnt plug and play, you might have problems with IO port clashes with its Adlib and Gameport against the AWE32, I think they are the only two things on both cards whose address you cant change.

date codes on chips are from March 1995, seems passable

Title says 1995.06 but your signature says 1995.05. You ain't foolin' me OP!

it is not a problem, in some rigs i use three sound cards, they work perfectly together.

the pcb is from aug 1995, i think the 1995q3 is correct.

that cpu and ram both have '96 date codes FYI.

if i would follow the manufacturing dates - i never could build anything 😀
the cpu is the closest model (p54c core, not the late 0.35 micron version), and the ram types / release dates are unidentifiable until the early 2000.

i have found an interesing source from feb 1995, with ark2000 info:
http://www.chiark.greenend.org.uk/~andrewm/Do … eo-card_faq.txt

yeah, it is the hercules, and not the diamond, but the hercules card design looks very similar to the diamond (reference design?). anyway, it fits to my socket 5 frame.

Some very nice pieces there - I really dig the Matrox. Also had a CT3910 running in a system a few days ago and even though it only has 512K onboard ram Warcraft sounded really nice.

Is the GUS "worth" the price?

Of you want to watch demos. For games - definitely not.

Ok, there's only two games(DoomII and Warcraft) for which, if the GUS were "better", I may have put in the necessary monies. I got curious after seeing a few videos about the GUS.

From the midi aspect, it depends on the game. Some is better, some not. But the swmix for the voices is weak, the cpu consumption is very high eg in the doom. Another issue the compatibility (as native gus), some games does not like it.

The mod based games with the hwmix are very good (mostly the pinballs).

Your CPU seems to be 1996 made if you care about strict dates 😀

I really like this build a lot congratz man.
Dates like that are pretty irrelevant when you are using what is considered Maxed out hardware.
A analogy would be something like 2006 Stereo headphones comparison, and the example that is used is not only the most expensive pair but costs 10 times the average pair in your round off. Then the person is like my stereo headphones are period correct. 🤣

To give it context Linus tech tips reviewed a 35 thousand dollar pair of headphones. In 20 years maybe someone will think owning a pair of those is period correct who knows.
