Re: Adding PS/2 mouse components to a Chaintech 486SPM

Hmm. Look like 486 SPM is really fast. I got some 32MB 50ns EDO single sided SIMMs and it seem that this motherboard do not support them. Is there any advantage caompared to FPM? And how fast is compared to famous Aopen AP43? Are there any tests? Is it possible to make PS/2 mod for AP43 too? Thanks …

Hi guys, I soldered the rest of the parts and this mod works. I must only replace both big inductors for the smaller ones. But I ordered them. Thank you Feipoa!

I thought that the rest parts are required only for volt regulator. I dont have SMD capacitors 47 pF right now. It will take a few days. I let you now than. Thank you.

Hi. I own Chaintech 486SPM Rev. M103 with BIOS labelled 02/08/96. I made this mod with original PS/2 connectors and PS/2 mouse does not work. Keyboard works. I "beeped" all the traces and I found out that all 4 lines of the PS/2 mouse spots are connected +5V/ground and data and clock to VT82C42N …

By default, the 3D-XG routes the output from the YMF715E through the A/D inputs of the DB60XG. This requires proper SysEx initialization of the DB60XG's A/D parts. Mediatrix' INIT3DXG utility provides this functionality, whereas the SETUPSA utility does not, resulting in the behavior you've …

What's so bad about the Audician32 supplied software? Last time I used the card it worked quite well! I believe there was one effect setting I was advised to disable in the INI but otherwise it sounded pretty sweet :) Oh and the wavetable header location is a bit annoying but I use external units …

I have finally flashed the BIOS. I downloaded FLASH.EXE wihout a readme file. Than I found the FLASH.EXE with readme file and I have found out that FLASH.EXE + DOS4GW.EXE + *.ROM file must be placed in a temporary directory. That is all.

Thank you for an explanation of that. I did not catch this You only need to send simple 8-bit commands to an OPL2/OPL3 chip. The original AdLib card with OPL2 was an 8-bit card, and later cards with OPL3 were designed to be fully backward compatible, so the FM-part still works the same as on the 8- …

Not sure what you mean with 8-bit or 16-bit. Are you talking about the ISA slot, or about the DAC? I thought 16-bit sampling not the bus. Are OPL3 chips able to play 16-bit samples or only 8-bit? Or does exist hte games with 16-bit FM synthesis? As I gave an example Aztech cards (meant Basic 16 and …

Maybe stupid question. Is WSS supported under pure DOS or only in Windows DOS prompts? WSS was released first for Windows 3.1. If WSS is only for pure DOS so GUS MAX must play the same like GUS Classic.
