Yes, that's a good point - changing the ISA video card might help. I would really like to run some tests, like that. When I ordered the 386 mobo, I also bought some ISA video cards from a seller in the USA. (I don't own a single ISA video card, but that's just changed!) Very luckily, there was this …

RG100 has a original game blaster. IMO much more interesting than an Adlib card LOL I got it from our good friend here on Vogons, Salient. Also, I have bought his Disney Sound Source module, which makes another interesting acquisition. :happy: I only began collecting PC stuff about 2.5 years ago, …

Aren't there some speed sensitive games, around the 386 / 1990s era? Some of these games run on a "maxed out" 386 DX might run a bit too fast. But if you drop the speed slightly, to act more like a low to mid range 386 DX, then these games might run at a more favourable speed rate. That's why I am …

Thanks very much for those extra tests - really appreciate that. What do you guys think about this: I managed to get 3DBench to produce every result number between 1 and 16, using a 486. I got the different results by changing its bus speed, cache settings, BIOS settings, and turbo status. To me, it …

Thanks very much for the info people. I was a bit late, when I joined the retro party, and there are some things I never managed to find, at a reasonable price. An Ad Lib card was one of them, and another was the LAPC-i. I did find a CM-32L and MT-32, so that's OK, but as for the Ad Lib - well, I …

OK, great! :happy: Looking at this mobo, the oscillator is socketed, so I think it can be changed fairly easily. I wonder if it's possible to find and then remove a suitable osci from an old defective piece of hardware, to use for these kind of experiments. Also, has the seller shipped your item yet …

Welcome. I also have one of these PC Chips mobos, with the same PCB layout and revision number of 3.4. I talked about it here. I remember getting it to perform fairly well, by using EDO SIMMs, and maxing out the mobo's BIOS settings.

This might be interesting: http://www.costronic.com.tw/Ev71p.htm Not sure how much it costs, if you go to thier homepage it asks you to email an enquiry. The info underneath the pics says that you need to write a device driver yourself. Could be very tricky, if you're not in to that kind of thing. …

Excellent info, people! @DK, I see that you have tested your mobo @ ~7, 8 and 10 MHz bus speed. Perhaps understandably, there are no documented settings to reduce this bus speed, and also understandably, any increases result in failure. I believe in theory, if you were to replace your CPU with a …
What does an Ad Lib sound card sound like?
Posted on 2011-01-02, 15:00
I would like to hear some recordings of old DOS games using either the Ad Lib sound card, or the Ad Lib gold sound card. Also, does the Creative 8-bit (or 16-bit) Soundblaster do a good job of emulating the Ad Lib card? Is the quality OK, if you compare the two cards' music output?

I might try the /10 jumper setting which should give a 4MHz ISA bus speed and do some benchmarks. It would be great to see a benchmark scores table for this mobo populated fairly evenly. That is to say, you already have 3DBench scores of about 15, 10, 6 and also 3. What would be really good is if …

I would really like to know what speed range this mobo can produce. @DK reports that using the mobo's "top performance settings", Speedsys = 5.85, and 3DBench = 15.3. I would be very interested to see what this mobo's performance "range" is, when factors such as bus jumpers are altered, memory …

Edit: I bought those "3 chip" SIMMs, and I wonder if these are OK too - My guess is they should work fine. No guarantees though, but I can't really imagine your board to be so incompatible regarding memory. If it won't work with the memory you bought, imo the board would pretty much suck Hehe!! …
