Re: Cloning the AdLib Gold Surround Sound Module

it'd be really fun to clone the Gold! i think the "Gold Ctrl" should be fairly straightforward to implement in an FPGA. or possibly a CPLD, if it is simple. the YMZ263 looks hard to find so it should also go into the FPGA. The Gold CTRL will definitely fit a small CPLD, the only real thing it does …

Re: Tandy 1000 TL/2 + Upgrades

I think the best use case I've found for the computer so far are the old Sierra games up to SCI0. These all have good Tandy graphics and CMS support, and can also use EMS. There is an unofficial Tandy high-res driver for SCI1 VGA games, though: http://www.vcfed.org/forum/showthread.php?30424-Tandy …

Re: TNDLPT : Tandy Sound on parallel port

I purchased a TNDLPT from Serdaco but noticed that it didn't render the music in Maniac Mansion or Zak Mckracken quite right (the noise tracks dropped out). No fault of the TNDLPT design, it was actually because the original TI chips used in the PCJR and widely available for re-use in the TNDLPT …

Re: CGA Replica / Potential New-Design CGA Card

Maybe I should have clarified my question a bit more. From what I have understood of how the shared video memory in the Tandy 1000 (and the PCjr?) worked, is that it encompassed the first (lowest) 128KB of the conventional memory. And since (I assume) any existing on-board memory in most PC/XT …

Re: Unknown Soundcard

this soundcard (i think it is one) is laying around here quite a while and i am wondering what brand/type it is. Googling was not successfull so far. Maybe some one on the Forum has a clue what it could be ? No idea about the brand, but the type of sound card is stupidly obvious: It's an AdLib …

Incidentally, he also posted to the thread that is linked above a couple of days ago. According to his own words, he still plans to publish his design files at some point …

Re: Do you want an EGA monitor?

The BIOS-less Hercules InColor scaled the MDA timings programmed by the system BIOS to something within the specifications of EGA monitors by replacing the 16.257MHz oscillator with a 19MHz oscillator. That trick should work with an MDA, too. By the way: The MDA can then technically output 16 colors …

Re: EGA/CGA card or ?

That being said, the digital RGBI signals from a CGA card or an EGA card in one of the 200-line modes can be converted to analog RGB with very little circuitry. The resulting analog signal is what the scaler board wants as input. If it wants a composite sync signal, add an XOR gate with hsync and …
