Does the monitor still have raster when the picture disappears? A quick way to check this is to crank up the brightness until black becomes gray, that way you can see if it's just the picture blanking out or you're losing raster entirely. If you're losing raster it could be the horizontal …

You also might want to recap it with some good quality capacitors. The ones presently on there may give you a headache down the road. EDIT: The AGP universal is definitely nice for the 2x cards, like a 2x Voodoo 5500.

I'd say it's a failing electrolytic capacitor, located on from most to least likely: +200V supply for the cathodes B+ filter capacitor Main power supply capacitor Thanks for the tip; I just got the thing apart (which was hideously difficult). I'll need to order some of the larger caps from digikey …

The IBM 6325, also known as '15V' as per the label on the front was the last official Personal System/2 monitor--succeeded the 'grey faced' ones-- released with the last series of PS/2s (then after came the P and G series of CRTs, like the rather available P70). Windows 95 strangely even has a …

It's a huge problem with foams as well. Such as the insulating foam in Personal System/2s, or Polymoogs (which it gets really nasty as they layered it behind the front panel). You end up needing crazy industrial solutions to remove the residue... The foam and rubber that experiences the 'melt to …

Strange indeed! As Phil stated earlier, new entries are always welcome! Okay what I'll do is test the model 95 with an MCA VGA card, and then I'll leave the model 33 with its XGA (which is VGA compatible), just for the sake of bizarreness as there aren't any XGA entries yet. One thing I did forget …

So I finally got around to booting with diskettes and no SCSI or SCSI controller... However, it appears GODS is coded to detect if it's being ran on A:\ and will then will refuse with: "attempt to run from non-original disk". I went ahead and edited the GODS DOS executable with a hex editor, but …

I can bench some of my PS/2s if it would help (the PS/2E or model 33 has a 486SLC @ 50 Mhz which is quite a unique processor, and the PS/2 95 has a pentium 60 with insane cache running on synchrostream). So both of those processors will perform unusually faster than their 'regular' counterparts. …

I had issues with MPU-401AT and a PCI SATA card. Games such as Gateway would lock up the machine. Question: Does your BIOS have an option for ACPI? Of so, disable it. Is there no way you can try the system without the SCSI card? The computer was made in 1991, so thankfully there is no ACPI (which …

Regarding Gods, it's a lapc-i / cm-32l game , not a mt-32 one. Some weirdness in playback is to be expected (nothing severe as the problem described here though) with uploaded samples, they sound wrong. Well GODS should still respond to the MPU-IMC even if it sounds incorrect with earlier devices. …

Okay after a frustrating time with the 'dial-a-pirate', I finally got the floppy version working. The MPU-IMC works with monkey island 1 just fine. I tried GODS again, the MT-32 receives no MIDI signals from the MPU-IMC. Hmmmmm. EDIT: Well I will be getting a 2nd revision 'head phones' MT-32 pretty …

I tried playing Monkey Island 2 and the MPU-IMC worked fine for it (the sound setup asks for the address instead of IRQ, which I have mine at 330 of course). I'm still in the process of getting Monkey Island 1 (the floppy version for proper MT-32 output). I will report back after I test it out.

Certain games will not work if you cannot use IRQ2/9, see here : https://github.com/bjt42/softmpu/wiki/Compatible-Intelligent-Mode-Games As you are using a Pentium-type PS/2, there could be a speed issue that the CPU is too fast for the MT-32 driver. Hello, Yes there are some speed issues and IRQ …

Dune 1 sounds *terrible* with the MT-32! The reason being is they did a very poor port of the adlib music; I was horrified when I first heard it. It was designed for the Adlib Gold (and is one of the few games to support the optional surround sound module). While there are still a handful of Adlib …

Do these games fit on a floppy? You really should test with the default IRQ 2/9 to rule out an Interrupt issue. The MPU-IMC does not support IRQ 2, and cannot be used on IRQ 9 due to the aforementioned conflict with SCSI (and it must be present so the system can see its 'convenience partition'): …

The MPU-IMC has no timing issues whatsoever thankfully. The reason why some 16-bit MCA cards have trouble in faster PS/2s (like Pentiums such as my PS/2) is because they use low-speed schottkys; which if replaced with ALS or 'F' variants, resolves the problem. So typically OEMs cheapened out to use …

Hello, If anyone was wondering my previous account was unrecoverable so I had to create another one (the email address it was registered to was no longer valid so I couldn't do the mandatory password reset). I have one problem with the MPU-IMC (microchannel MPU-401). On certain games, it seems like …
