OK, got a replacement board in now. Its a P3V133 board, so I have an extra ISA/PCI slot. It's also ATX so a "little bit" more space. Not much, still having to go with a mini-tower so it will fit in the space I have for it, but I can keep most of the airflow clear anyways. Only problem is the MB seems to need the -5V input from the ATX. Just discovered that a lot of recent PSUs don't have that line for some strange reason. Literally, no wire in the spot, just an empty socket.... So, my 500W PSU I was going to use had to be removed. With 3 HDDs, CD-ROM, 2 Floppies, 2 VooDoo IIs, SB AWE32, MPU-401AT w/SCB-55, S3 Savage 4, & 10/100/1000 NIC I figured it might need it. But it won't work with that PSU. So I have to use the only PSU I have that includes the -5V line... It's only 300W. I hope it's enough 😒
Other than that, it works great. PIII 800Mhz w/ 100Mhz FSB. 256MB PC133 RAM (I might upgrade to 133Mhz FSB some day.) It's actually capable of going up to 1.5GB but I'm not planning to go over 386MB. Heck, I don't really plan to go over 256. Not much call for it with Win98 or DOS6.22 (or Win3.1 for that matter.) My next test (once I get audio going,) is to see how it performs with both caches turned off. The only thing I'm really missing is the ability to underclock it in BIOS like my 2 failed MBs could 🙁 Oh well, there are other options for that.
Only thing left is to wait for my audio equipment to come in. It's the 3rd so I was able to order what I needed. Decided to just get a pair of speakers and a simple 4 channel (stereo,) mixer. Since the 2 Amigas, this PC, the MPU-401AT, and the MT-32 are all stereo (and not quadraphonic,) they'll be all that's on the mixer. My modern system will use the 4.1 speakers I have. The MPU, MT32, and eventually the CM32L will go through a basic audio switch box. All that stuff is scheduled (according to Amazon and eBay,) to arrive next Wednesday and Thursday. Getting a mixer, speakers, switch box, and all the necessary cables for only $40 (all with very good reviews.) So I think I'm doing well there 😀 Went ahead and got everything needed to add the CM32 as well, so if/when I find one, all I'll need to do is plug it in.
To be honest, there were several mixers that came soooooo close to being perfect. But every time I'd say, "Ooh, this is just what I need," I'd find a problem. What would be perfect.... 8 stereo inputs (DOS System, SCB-55, MT-32, CM-32L, Amiga 2000, Amiga 4000, Modern System Front, & Modern System Back.) 2 stereo outputs (Front Speakers & Back Speakers.) The ability to set each input to one or both outputs. Best would be both a balance (left-right) and a fade (output 1-output 2) for every channel. What I do "not" need... 5001 special effects dials that I'll never touch. 20 microphone inputs that I'll never use (or will have to "fake" into stereo inputs to get the 8.) ANY mono conversions (really, why do so many "expensive" mixers take stereo input and turn it to mono before sending a stereo output????) Headphone output, (ok, I would probably use it if I had it, but I don't really need it.) Really, it's that stupid (IMHO,) wasteful conversion of stereo to mono that is the primary culprit in ruining otherwise perfect mixers 🙁
