I tried that and it didn't move the cursor..maybe the keyboard only works with the drag cart? Hmm Guess I need to do some more testing.

Have you done the dateline fix on the ACIA ? And also connected the missing GND connection on the keyboard connector ?

Also the color bands in the test cart have fewer levels per color than a standard ST. I'm going to play with the monitor intensity to see if its just over driven but it does look like it. The first pic is from a real ST while the second is from the remake which has less levels per color.
It's possible your Monitor lead has series resistors in lowering the intensity of the RGB drivers?

The color gradient was interesting btw. If you got all the resistors in the right positions then there seems to be a general case of too much resistance on the RGB lines :)

Working on the mouse which doesn't make any sense. The arrow keys don't move the cursor. The mouse doesn't move the cursor however the mouse and all keys work fine with the diagCart. Yes, the ACIA fixes are in. I don't believe the cart would work if they weren't.. :?: :?: :?: The parallel interface is failing again. The only time it passes is when the digital analyzer is connected. Cart docs say parallel interface can only drive 2.2k pull-ups. I may try some 10k pull-ups here. Changed the 2149, 68901, 6850,and no effect.

May be a bad solder joint? Mostly what bugged my board was bad soldering.

So far everything looks ok... I'm a little stumped why it works with the cart and not TOS? The only possible differience I can think of is TOS may get characters based on an interrupt and the cart may poll. Hmm Maybe the wrong MIDI OPTO is at the heart of this issue.. going to pop the MIDI 6850..

OK spots fans.. one bad assumption can cause a lot of trouble!! :smackbum: :smackbum: :smackbum: Wrong OPTO must have caused the MIDI ACIA to believe it had data.. both ACIAs on same IRQ so it never got to serial, alway servicing MIDI. Pop the MIDI ACIA out be have mouse! :dizzy: :dizzy: :dizzy: !

Glad you got to the bottom of it.

Going to make an expendable disk for the Ultra Satan and see if it plays nice with the floppy.
