New Driver for Port Redirection without need of QEMM386 or EMM386 is in development.

How about decoding another port on the card? Port B0 or port E0 are good candidates, this will make patching games a lot easier.

Maybe..
biggest issue are still the bios check of the tandy games 😳

Had time to retest all changes on real pcb.

accidently dropped some solder on one of the card fingers 😁

Almost ready now.
Just need some time to drill my bracklets soon 😀

I also noticed someone on ebay sales tandy pcbs but they are the old jj_pearce design, no muting, and pc-speaker MixIn can shortcircuit mainboard.

I need one of these new ones matze79 😁
tbh I have not tried or patched the older version yet 😵 - it will be kept as-is for archival reasons along with the rest of alpha/beta stuff I have 😊

Looking good, and very tempting to buy if they become available at some point.

The more sound cards, the better.

Adress Encoder is expanded to support 0E0 and also 2E0 for easier Patching 😀

if you have existing card / lo-tech Card and want to use 0E0 just connect Pin 16 of 74HC688 to VCC. Or for normal 0C0 to GND.

But i see no benefit, games running on 0C0 are always running on my 386/486 without Problems
and on my Pentium 3 i can not access low adress ranges at all, only 1E0 and 2C0 works here.

And for DMA issues ? i did not encountered one yet but i also did not many heavy testings with SB Cards installed.
I use it mostly in XT Systems and my Testing 486 😀

"periodic noise" is not the right term to use, it actually is a 6.666% duty cycle square wave (and 6.25% on SEGA VDP PSG). LFSR is operated without feedback so one single bit circles through 15 stages (16 on VDP) the register is long.
