Today, after some prolonged troubleshooting, I've finally experienced Quake on original Intel Batman board with Pentium 60. It was horrible, as expected.

After how many hours? six?

Making a PC/104 to ISA riser, it might work, it's cheaper than buying an old stock one and this one has an ATX power connector 😁 Much easier than trying to solder one up. Honestly whoever made the PC/104 16-bit connector, I dislike them, it's so bad to route to a 16-bit ISA slot.

I've been fighting with that cursed Intel board around 2 hours.

nice, but... umm, why didn't you just route them straight out? the PC104 pinout follows exactly the same order as ISA, you did for some pins but then start to mix and match? ^^
I can't quite follow some traces on that image.

...but I should probably try that sometime myself before x3

Hopefully the fight was much better than the game itself. 🤣

The 16-bit section is in a really awkward position & direction for routing straight out to the 16-bit of an ISA slot with the 8-bit section directly over it. It's slightly impossible to follow with just one side of the board, and would be much easier with a 4 layer board to do ground and power planes. But the autorouter did this for me, I can't claim much credit beyond putting all the pins in the right places (and checking their location with a multimeter before proceeding)

I much prefer 4 layers PCB at a minimum and few bulk capacitors sized for polymers and few 4.7uf 16V MLCC. You can't imagine how much noise things makes with 2 layer boards especially for improving audio quality.

Finding 4 layers ISA i/o card with fully buffered IDE, and resistors in series of correctly done IDE is nearly impossible.

Also, same problem with ISA video cards. I managed to find some and purchased one.

Testing two ISA WD video cards (90C30-LR and 90C31-LR) in compaq deskpro 386/25e. Actually the compaq's onboard video chipset is faster when I do dir of dos directory. I know this is crude check but that all I have time for.

Was it faster than what I had to deal with on an i486DX4-100 I wonder..

Quake? Obviously faster. After overclocking to 66 MHz, timedemo scored 19.9 fps with Matrox Mystique. Interesting platform from historic POV, but totally not worth resoldering/modding dead RTC for some benchmarks.

I was happily enjoying my new(ish) ESS AudioDrive ES1868F when I decided to play an old favorite of mine, Xargon. I was immediately startled by how damned loud the music was! I quickly turned the speakers down and shock turned to despair when I realized how distorted the audio was... did I just blow out my speakers???

I did some testing and found to my relief that the speakers were fine (they are pretty nice speakers). To make a long story short, I figured since the card does not have a separate "speaker" and "line out" output, it must have some builtin amp—and a way to enable or disable it. Some research showed that the two jumpers (JP1 and JP2) needed to both be set to positions 2-3 to disable the amp... and sure enough, I had mine set to the factory default (positions 1-2; amp enabled). Switching the jumpers fixed the issue, and now it sounds glorious indeed, even when playing XARGON!

I really like this card! The FM synth is not 100% accurate to the OPL2/3, but it's pretty close and it sounds very clean. I definitely prefer it to the CQM synth of the AWE32/64 (my previous card), which I actually didn't mind too much.

My favorite Atari computer model and this one cleaned up nicely. Still had factory plastic over the function keys. Yes, the ST line was nice and the TT030 was a piece of hardware art, but the 800XL holds a special place in gaming history for me.

The 800XL is my favorite, too. The Atari -XL series is the first computer I ever touched, inherited from my older brother (likely a 600XL). I've got an 800XL along with the Lotharek sio2sd (though not in such a nice case as yours!), and it's a lot of fun. Great keyboard to type on, and I still think it's the best looking micro out there.

The HDD for the Versa P/75 came in yesterday (80GB Seagate Momentous 2.5" IDE ATA-133). As of now, it's running Windows 95 and now goes the long and paitient process of pushing software to the 80GB HDD for installation/configuration/setup. I found out the P/75 has the 800x600 screen on it (might have to try that out on the M/75 sometime) - probably also explains why the hinges have not blown up on it (yet) - seems the touch screen and 800x600 had the best hinge design on these laptops. The Memory Card (32MB) Comes in today giving it a total of 40MB of RAM (32MB + the 8MB on the Motherboard) - so it should be pretty fast for what it is.

I also made a discovery. So the other night while messing with the P/75 to test out the ESS 688 Audio Drive in it - I decided on a whim to briefly do the "short trick" on the aftermarket battery it came with and put the battery in my M/75 which is getting daily use as of late. Thinking nothing of it, I went to bed, woke up at 6 a.m. - and found the cats knocked the power plug out of the Versa while I was asleep....well I'll be if that thing was not running under that battery on it's own - I got a good 30 minutes out of it before work playing Hoyle Card Games and MicroLInk Yahtzee on it before going to work. At work I just let it sit idle and run under it's own power off full charges to exercise the battery a bit - I was batting between 30 minutes to a full hour thirty out of that thing depending on screen contrast......looking forward to being outside and doing some sunshine gaming on these beasts on my patio in between rounds of working on the Les Paul copy guitar I'm rebuilding.

I guess I now have what I wanted - a fully mobile DOS system (M/75) - and apparently also a fully mobile Windows 9x system as well (P/75)

I had the same with a ES1869F, the amplification was just too damn high. But I had something similar with the AWE64 where the 'Spk out' port was loud and noisy so I ended up using the 'Line out' port instead.

What are those pre-amplified signals meant? Were they for cheap, passive speakers that didn't have an amplifier (and were those still around around the time of the AWE64?). I don't think I ever saw such things.

Installed a coprocessor on my 386 motherboard. I know it doesn't do much, but I like it when it says it is present, on bootup.

What kind of cable did you use to hook your Atari to TV?

A composite A/V cable.

I seem to recall that LGR mentioned the same about the sound volume of Xargon on one of his latest videos (the one where he reviews a new MCA sound card) so maybe it's the game, not your soundcard.

Nice and Hahhaaa ! I did same with a couple 286 and one 386. Yep ! does not do much much for regular use but maybe Quttro Pro or other app may make use of it 😀

Hate posting a reply and have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. 🤣 Second computer a 286 12Mhz with real IDE drive ! After that came 386, 486, Pentium, P.Pro and everything after....
