Hmmm. Test voltage on the Mono detect pin of the shifter... always 0v.. strange. I notice in the schematic the mono pin on the shifter is pulled to ground by a resister, and goes to the 'base' of a small transister before going to the socket.
OK, Try a spare shifter chip...... I see about 2.5v in mono mode, and 0v in colour, and the ST has a picture again. phew. Swap back,..gone. Ok chip buggered. Plus the screen darkens when the meter touches the pin.... careful....
Fantastic work you're doing
I've emailed you about an HD kit.
I guess I can't PM because I'm new

Sadly, the STacy runs a 2 chip 1.4 TOS.. and is difficult to offer you modified ROMs for 1.44Mb Booting...... But not impossible....just more challenging....

Didn't recieve the email..?!..but no matter. There are 3 boards sitting here waiting for someone that wants it.
I will have the new HD Sony drives sometime this week. All modded and ready to go after some brief work... Want one too?
When you can, PM me your address, And I'll add you to the list.

This site mentions a disk change detect/mod... are you finding any hassles regarding disk swap detection?
I have always pressed ESC when changing a disk to update folder.. and it always show the new disk contents..
My batch of 4 Sony drives will be here next week or so (2 white, 2 black) .. I'll test them all and modify them the same as you have.. DS0/HD.. and maybe disk change...
Might keep one for my ST.(But not modded for DS0, I modded my cable ) More available online from the sellers if I need more.
Interesting that mod is nothing like ppera using WP pin for similar result.

When in an application, I use the other drive, or access a disk in the other drive, then swap back (but this does not always work! ).
On the machines that have TOS 1.04 or higher, I still tend to automatically press [Esc], but don't remember too many problems. Having said that, I also use NeoDesk on some of them as well...
