Re: Lightning VME open Order

Create Partition on that USB drive, with partitions upto 512MB, before this go to compatibility and check Tos and Windows Compatible (no Byteswap).

Then the stick is usabel using TOS and Windows (Windows 10 supports more then one partition on USB Drives)

Re: phantom bus accelerator & clock patch

The Volage isnt the problem, the Problem is the Timing , a F type 74F04 has 4ns per gate. Instead 20ns or so with LS or 7404. And when you put it through 2 gates then you have 20ns.

Its more an timing issue instead of Voltage!!

Re: phantom bus accelerator & clock patch

Just some thoughts, i think you give the SDMA more time to take over the Data. I tested it alot and also instable falcons are working better with this patch. Feel free to try it out! Its just how i do it, you can do what you want ;)

Re: phantom bus accelerator & clock patch

You have to use a extra gate for the sdma line, to get more time, then it is working well! Tested it on weekend again.

I have connected Pin 2 +3 together and 4 and 5 together, pin 6 connect the wire to SDMA

Pin 1 Input from Mainboard
Pin 2 Inverted Output
No extra capacitor is necessary!
