Maybe this video I recently stumbled upon helps (how to identify fake Pentiums): https://www.youtube.com/watch?v=wsKjX6UGYUQ If the chip is somehow reprinted you usually don't get the typical very sharp 45° chamfered edges on the ceramic package. On the other hand ... the intel marking is indeed …

Incredible project 😀 I had actually considered to do something similar once I'm done with the ARGUS, as those S3 VLB rarely cards pop up on eBay and if they do they're usually quite expensive. Looking forward to replace the CL5428 in my 486 system with your card once it's ready.

Apparently mine is a Version 1.7 (with the smaller JP16-20 block compared to the 2.x versions). BIOS is 04.02 Beta, also tried the official 04.02, 04.01 and the original version the board came with (unknown revision, but this one only supports 1 IDE channel - dated 04/26/94). I've found your post on …

Bug for FDOOM2 (486) - start up Map01, kill some zombiemen on the stairs. Take out chainsaw and saw away. Bulletpuffs will appear in mid air when standing on/near a corpse. Also music support for Gravis UltraSound appears to be broken.

Thanks for the recordings. They sound absolutely alright. This indicates that the mainboard probably is the source of the issue. It's an Asus VL/I-486SV2GX4. I've already tried to adapt the jumper settings from DX2/DX2SL to P24T (which the POD is identified as) sadly the machine hangs after post …

It's still doesn't make you run Quake so theres no point in this CPU. Usually see like 19-20 FPS in quake, its probably not fast enough to run duke nukem 3d at reasonable FPS either. Maybe if you have a PCI board and slot a voodoo 1 u can run quake lol. Bit late to the party, but I managed to …

Thanks a lot Whiskey - this really increases the value of this project. On the other hand - I found a potential issue that might be worth investigating. Does anyone of you have an ARGUS or GUS PnP in a system with a Pentium Overdrive? I just recieved my PODP5V83 and installed it in my 486 system …

No. Please refer to the large, bold & underlined text in the very first post of this thread. You could always buy a GUSAR tho.

Bad news once again ... lost my job yesterday (on the day I was with the company for exactly 1 year) even tho my contract was limited to 2 years. Intended to celebrate it with my workmates, when the head of department called at 8:20am, that my termination letter was just sent off via courier. …

What 640k said ... additionally the InterWave doesn't have support for CDROM drives ... therefore additional circuitry would be required (likely 2 bus drivers + a GAL/decoder) ... therefore not gonna happen on the ARGUS and not exactly a useful feature in my definition either.

Considering this thread is already borderline with the admins (I did ask before opening this thread or rather as it developed) since the sale/wanted section was removed for a reason. I'm going with Synoptic's and 640k's opinion as well.

Hot air is great for reworking stuff, without doubt ... but for assembling I prefer the good ol' iron + flux + wick technique. For assembling you need some really good quality solder paste, which usually isn't cheap.

Before I forget, I thought I'd mention one observation about the RC-1 design, even though it's not likely to be integrated (we did agree to no changes unless something is broken): C14 should ideally be a low-tolerance C0G/NP0 part. It seems that these are usually stocked in 1206 or 1210 form, and …
