Re: First PAK board attempt...

Those little Picos are awesome.. I have one in my AMD64 that runs the media center in my car (90w I think). On board computing is a great thing. music/videos, and internet when in 3G or WiFi range. The less I use the 240v inverter the better. Sucks too much power and drops out early. ST. :cheers: Mi...

If I am having a bad day Ron- I'll visit your thread.

Misery loves company... Seeing someone else trying really hard to do good things- and crazy annoying stupid things going wrong, is rather amusing in a dark kind of way. :mrgreen:

Chin up mate... you're nearly there!!!

Re: First PAK board attempt...

The way I read Marks posts, using an IC to combine V & H sync for a new composite does away with the modulator.

Unless I'm mistaken. It should work.

Re: First PAK board attempt...

Back from Vacation.

How about.. that new version of the GBS v5.0 has a LCD connector instead of a second VGA output.

Would there be a lcd panel that would fit the STacy screen hole and give color!

Now that is a project.

Re: GBS-8220 to Atari ST (2012 topic)

I hadn't bothered to buy one my self.. but now I will just to see the drama. So to be annoying- instead of resisters in the simple version, why not a pair of signal diodes? It would drop the voltage a bit too as a bonus. 1N4148 or similar. Then the lines wouldn't been see as a short to the Atari. Ot...

Re: Wires connected to goldstar and yamaha chips.

You're right.. The Mono detect & Previously GP0 output is exchanged for 'Genlock input', they are fed to a 74S257 chip, clocked with 32Mhz. Generating a new 'MonoMon' signal sent almost to IO7 (like a normal ST mono detect pin.. but different, also altered with interupts from XSint).. And still with...

Re: Wires connected to goldstar and yamaha chips.

No... not nothing to do the bad DMA issues..... @dml has the idea. Its a botch job. Detailed comparison between the STFM schematics and STE shows an unusual wiring alteration to TA1 by instead being connected back to the IO0 output of the same MFP (& incidently the #Busy signal of the parallel port)...

Re: Atari PCF554 - Can it be used with an ST?

I used a 5 1/4" drive many year ago - along with my AtSpeedC16... To use one of these drives.. the 'software modification' is a step rate adjustment. These old drives don't like the 3ms pulse of the ST. We need to bring it back to 6ms. STEP6M.zip You'll need software like FCopyPro to format discs. H...

Re: Time for a "SuperNova"?

Which is almost exactly what the cartridge based 'NetUS-Bee' did. Use a real 'RTL8019 chip' for the ethernet port... remove the ISA implementation crap, and simplify it.

See the solution forming.

You know, the track work to connect a ET4000 to a Mega ST (or ST) to the cpu/expansion bus is really minimal. I don't have access to my data drive for at least a while, but the diagrams are online around the place. Surely a FPGA version would be the smallest solution to do away with the ISA connecte...
