Thanks, that helps me understand the use case for dual-MPU configs a bit better. I have been using Unisound but notice that ORPHINIT has mixer control over the wavetable volume separate to FM, that seems like it should do the trick and not risk getting stomped by games making their own mixer …

Maybe this is a stupid question, but how do I disable the wavetable synth so I can use an external MIDI device to mix with Digital audio? Is it just a matter of reducing the FM volume to 0?

What version of DOS exactly are you running (show output of "ver")? Both PC/MS-DOS 3.3 support the goto/label batch commands and it does work fine locally when I try it.

You do not need to put up with CTMMSYS.SYS and CTSB16.SYS just to run the mixer. You need to update your drivers to a version that includes SBMIX.EXE which does not need the architecture TSRs to work; I think the update file SB16UP.EXE, wherever you find it, is the one you want.

You need more UMBs and fewer loaded drivers. EMS consumes a 64K page frame in upper memory, which wipes out an entire segment into which you would otherwise load modules, and there aren't that many segments to go around. You don't need SETVER or DISPLAY. If Arena doesn't run from a CD then you don't …

I was working the phones at Gateway 2000 when Windows 95 shipped. So from day one I saw the worst of it. 16-bit Windows and DOS application hell; legacy driver incompatibilities; installation issues; you name it. Still the most fun and most interesting version of Windows I've ever used. After Win95, …

What makes those games difficult to get working? A plain list of game names doesn't mean much to me. What's interesting about them? In my experience, games that push the envelope at the time of their release are the toughest to get working. Ultima VII: Had a requirement of both high free memory but …

For the interested, the EZMEM.SYS file is on the boot disk created by the EZDRIVE9.EXE program -- the one available as "9.03W" -- but not in the archive described as "9.06W". There is no readme or instructions about its purpose, use or method of operation, but it does do something: - Without EZMEM. …

I don't see any options for PIO in my BIOS. I think older systems had jumpers on the controller card for this... Now that I think of it, didn't some controller cards have configuration software? What model controller cards are you working with? Yes, there may be jumpers on a VLB IO card for PIO …

Only if you want to tinker with hardware stuff instead of playing something. Sure, but only once, then the system is set up forever. If you really dislike tinkering with hardware, there's always DosBox.

Why? More problems with setting everything up (jumpers, cache policy, memory chipset limitations, etc). Usually HDD size is limited more. Very picky with system bus speed and also can be unstable with 3 VLB cards installed. Can't install USB / decent network card for quick file management. Hard to …

VLB cards tend to more expensive because they were produced in smaller numbers and there is demand for them. There is nothing wrong with a VLB 486 (some of us prefer them). If you can get a VLB setup cheaply then go for it. That’s not really a compelling reason to avoid VLB boards. You’re not …

PCs don’t care whether there’s a floppy present or not. You should always at least be able to disable it in the BIOS or at least turn off seek-at-boot and/or the a:/c: boot order. I only plug in a floppy sometimes on my open frame builds, and there’s never an issue having it disconnected.

The old Access games with "RealSound" suggested using a 4.7uF capacitor in series with the speaker signal and connecting it to line or aux in of a stereo. The "Mean Streets" manual had instructions for this. Copy code to clipboard 1 PC SPK ----- (+) 4.7uF (-) --==-- 2 GND ------------------------/

Do partitions always need to be separate drive letters? The answer to this is "yes and no". Initially, a partition or logical drive needs to be assigned to a drive letter and formatted before it can be used. This is always true for DOS. After that, though, you can use the JOIN.EXE utility (on the …
