@tubetime A Panic button is essential functionality for every MIDI device. Also conveniently placed right next to the power button. This checks all boxes.

@tubetime Oof! This panic button is dangerously close to the power switch. As a testimony to the robustness of the midi protocol (ahem), the need for such a button is VERY real in live settings. Simply disconnecting cables or powering off won't do.

@tubetime Can I install that in my Apple silicon Mac and get back FLOAT80 support? 🤔

@tubetime I had an 8086 board for my CP/M machine, a NorthStar Advantage. It ran DOS 2.0, which could be configured to use forward slashes in paths. Eventually I got an 8087 daughter board for this machine. It was fun while it lasted.

@tubetime That Quadro and WinTV card are offended. ;)

This must mean I’m also old if I’ve had several of these and can spot the sound blaster clones.

@tubetime Damn! Good thing I slept in as I have no use & space for this hp9825 but would have grabbed it regardless

@rdp yep. hmm, the 9845 with the power supply overvoltage was quite tricky to fix.

@tubetime the yellow box could also be interesting..
