The method for generating digital sounds on an Adlib is more resource intensive than a simple Covox. On the Covox, you can just send the bytes of your sample to the DAC. On the Adlib, you have to program a chip that is designed to produced modulated sine waves into a state which it can output a user …

I have read that HASL finishes can wear down to the copper in fewer than 100 insertions. A friend of mine and fellow forum member told me about a vintage card he acquired which had HASL finish on the edge connector. The guy who sold him the card had apparently removed the card in a way that the …

That is a very nice looking board and it has all the options anyone would ever seem to need. I have one question. The edge contacts of the old board are gold whereas the new board look silver in color. This suggests a HASL finish. I hope you aren't planning on using HASL in production boards.

Not all game ports have midi functionality . It was a trend that was introduced on sound card game ports by Creative Labs with the Sound Blasters featuring DSP 2.0 (as far as I know). Most sound cards followed this trend afterwards . I doubt any (Super) I/O cards had midi functionality on their …

Moreover, you need to start with the dumps of the built-in CM-32P Sample ROM and Control ROM and build out with the expansion cards. While the Sample ROM and Control ROM may be easy enough to dump, dumping the cards is going to be a tad more challenging. The CM-32P can shape the output of the …

So let's suppose that for some reason I have two controllers which are both classic game port style, and I want both hooked up (for reasons) at the same time. But.... as far as I know, the only way to get a game port is to install a sound card. There are three ways to get a game port in your PC. …

Does your program intercept a memory read to the BIOS at FC00:0000? Most games use the Tandy identifier byte there (21h) to determine whether to use Tandy sound, and to a lesser extent, Tandy graphics.

Something about that port doesn't seem right. I think it is the sheer number of knives that are dropped. My experiences with the MS-DOS port never give me as many. The EasyFlash cartridge uses a bankswitched 8KB ROM window, so the loss of 8KB of RAM is not particularly acute. ROM is a lot faster to …

The noise channel is missing from the SVN r4106 version from what I can hear. The noise is not gone, it just isn't being heard as it should due to the peculiar way the noise channel works on variants of the SN76496. The change occurred in SVN r4075. The change in that revision was "Merge the …
