Re: VCS - A capture utility for certain Datapath capture cards

I learned that alias mode requires a comma after each number, so 534,472,720,400 should work.
Re: Trying to add Amstrad PC1512 special video mode.
Posted on 2019-02-12, 17:10
It is not impossible, but the Amstrad PC-1512 was like the Tandy 1000 of many European countries, the first IBM PC compatible that was close to 100% compatible and sold for consumer-affordable prices. Amstrad hit it big as a result. The PC-1512 has its quirks when it came to CGA graphics, so putting …

I can't get the alias setting working with VCS 1.2.5. I have followed the readme's instructions. I created a text file with only the numbers 534 472 720 400 and the program refuses to load the file. The terminal states that "Expected a 4-parameter row in the alias file". Any ideas?
Re: List of SBPro (CT-1330) stereo YM3812 supported games?
Posted on 2019-01-11, 13:58
ripsaw8080 beat me to it. I must have used Cloudschatze's Quest Studios post because I list the same games as he did. I did touch up the language on the list. I had no idea there was some kind of Wayback Machine archive of the Quest Studios' forum. So much was lost when that forum went down, so I'm …
Re: MediaVision Thunderboard
Posted on 2019-01-06, 04:42
The Thunderboard is a cut-down clone of the Sound Blaster 1.5 with DSP v2.00. It does not have upgrade sockets for Game Blaster chips and cannot communicate with MIDI devices at all through the joystick port. The only advantage it has over the Sound Blaster 1.5 and its successors is that it has …

This no-name Adlib clone has a very nice PC Speaker passthrough. It's superior to the PC Speaker inputs on the Sound Blasters, which apply some filters that do ugly things to the sound.

Is there any Documentation how the DAC works ? :) Ahh i see.. These two activate the IBM PS/1 Audio Card. It is always situated at ports 0200, 0202-0204, so there's no need for a "base" value. is it dma driven ? or more like a covox device ? It's an in-between, think of it like a more capable …
Re: 3DFX cards - too expensive
Posted on 2018-12-03, 15:31
I think you really need to set your sights more on what you can afford vs. what you want. Voodoo 5s and Voodoo 2s seem to be the ones going for the most, so you may need to accept and embrace the less-expensive Voodoo, Voodoo Rush, Voodoo Banshee and Voodoo 3 cards. However, we are fortunate that …
Re: Covox Sound Master Reverse Engineering / Replica
Posted on 2018-11-11, 14:48
I think your current layout is "close enough", I'm definitely on board with one. I like that an AY-3-8910 or YM2149 can be used for the sound chip with only a slight reduction in game support. I'll fix that joystick error in my article. These Covoxes become more mysterious as we learn more about …
Re: Covox Sound Master Reverse Engineering / Replica
Posted on 2018-11-10, 15:07
But for the "original replica" what should be done? 1) Component placement and routing: a) should be left as close to original as possible (even if it degrades output quality and looks bad); b) can be re-done in some places to get some improvements; c) should be fully made from scratch (as an …

What do I need softwarewise? Can I simply fire up Zak McKracken or Maniac Mansion and it will detect the card? If you have the card configured for address C0h, it will just work as-is (on PC/XT class machines at least, ATs and newer have the second DMA controller at address C0h, in which case using …
Re: OPL3LPT : OPL3 FM Synthesis on parallel port
Posted on 2018-09-07, 13:06
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.
Re: No MIDI output on Game Port
Posted on 2018-07-31, 17:27
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 …
