Now i'm Searching a way to reset attiny on System Reset.

I think you could use B2 on the ISA bus.

RESET
This signal goes low when the machine is powered up. Driving it low will force a system reset. This signal goes high to reset the system during powerup, low line-voltage or hardware reset. ??????????????

As far as i understand you don't need an inverter.
Reset on B2 is low on running state and on bootup and reset it goes high.
And iirc ATTinys reset on high on the reset pin.
Edit:
Nope, i remembered wrong, you need an inverter.

Now i can Mix in PC-Speaker :)
But the adjustment range is too small.

Need to order few parts for testing, maybe i want to try another amp too.

Radovan from Slovakia re-eneneered Tandy and Adlib sound cards for PC/104 bus.
For me it is from outer space.

i hope i can repost his prototype picures from Oldkomp cs facebook group. If not, i will delete them.

After nearly 1 Year of work in rare free time i got now the first working PCB, with only one minor Fix in my hands:

DSC_0070.JPG


it worked out of the Box after soldering :D

Now there is still Stuff todo,

- bracklet design (3D Printer is ready! :D)
- Firmware improving of the MCU / seems feature isnt working properly on all Machines, remute LM386 on reset. (ISA Reset Signal)
- Writing proper muting utility,
- maybe dreamblaster/pdw will help with his tandy lpt tsr software by adding support for this card too, redirecting 2c0h to 0c0h for machines who can't support the lower adress.
(Pentium and higher ISA/PCI Bridge..)
- intense testing is required, so its time to play some Games :D
