I finally got a posting system. Ironically enough, the original board I thought was damaged by acid leakage, works. The SIS 85C461 Lucky Star motherboard has some other issue I haven't been able to pinpoint. What I found was that the Lucky Star motherboard does not post with the DiamondStar Pro VLB …

I remember back then it was more of a board about running LucasArts and Sierra compilations on Windows Vista. Yeah, that was a friendly takeover/silent coup. It used to be all about running v ery o ld g ames o n n ewer s ystems and "VOGOVOS" didn't quite have the same ring to it, so... Oh, freddled …

Yes, that’s because of the lower voltage. The original Intel 486 processor are 5v and generate more heat.

Thank you Deunan. Both RAM slots and cache slots are on the opposite side of the board. I’ve tried reseating the four sticks, but only on their banks, I haven’t tried moving them to the other banks. I’ve already removed the battery, started leaking a bit so I nicked it, applied vinegar, washed off …

Hey all! A couple of weeks ago I posted this: https://www.vogons.org/viewtopic.php?f=46&t=86644 Unfortunately after putting all jumpers were they go, the system won't post and there is no video signal from the VLB video card. I got a POST card. There are no error beeps, either with my old internal …

Hey Cuttoon! Sorry for the late reply, I think the email alerts are not turned on. Yes, that is correct, TI 486, it's actually in almost pristine condition. I'm attaching a picture. My motherboard does not have VRMs around the socket so I'm assuming there's no support for lower voltages. I'm still …

So what you're implying is that it's much easier and cheaper to just get an Intel 5V processor and that going with a lower voltage third party one (that can be more powerful, in line with a first-gen pentium) requires an adapter with an included VRM that can be more difficult to find and …

Hi all! A long while ago I posted that had come accross a GMB-486UNP Socket3 motherboard. Unfortunately at the time I didn't have all the components needed to put it together so I saved it for later. Before the pandemic hit, I took a look at it one day and realized the worst: it was sold to me with …

In my humble opinion, none. Roland made all their modules backwards compatible to their previous module, but that doesn’t mean accurate. The SC-55 has CM32L mode but it doesn’t sound exactly like a CM32L because it is Linear Arithmetic synthesis and the SC-55 is sample based synthesis. The SC-88 has …

IIRC, you can save several steps (and memory) by just putting midiconfig:1 This basically directs DOSBox to the USB device that interfaces with the MIDI port on your SC-55.

I just wish I knew why my line-in on my audio card wasn't working. You have to activate the loopback, unmute line-in and raise the volume. Pavucontrol is shit, just use alsamixer on your terminal. Change to your audio device using F6, move right until you reach loopback and turn it on using up/down …

Anyway, this is the MOBO: GMB-486UNP Socket3 motherboard + Intel 486 25 Mhz + 4 RAM + 256 cache VESA ISA Now, on another auction site I found a Texas Instruments …
