If they're so good why don't you post them here or on the Internet Archive?

Hi, USB PD 3.1 supports up to 240W, should be plenty for a TAM. It can only output one voltage at a time, you would need a power supply that converts its 20-48 VDC into your +5V, +12V, -12V rails. And it would have to work with the soft-power switch...

Is there a broken connection inside the PSU?

It's down again...

It would be very cool if this drive was reverse-engineered and new ones built. 1.44MB floppies on a Plus? The PEEL 18CV8P programmable logic chips used are supported by afterburner but are most likely read-protected and will need a special technique to dump them. As for the EPROM you can dump...

Affix to the end of each of your messages :)

I would prefer hot air... I've never owned a PowerMac and it isn't necessary. Just would like a more precise mechanical specification coming up so I know exactly where to place the footprints

Picture of hacksawed riser shows trace on slot B connecting all interrupt lines together. So I'm not sure why you'd think you've erred? I would like to start with schematics of a known-good riser. Even if your cable kludge worked, I'd rather do things by the book. If you need me to you may send...

Yeah, 0.01µF seems right. Are the purple pins on the illustration all GND?

Can't you just flip it around horizontally?

Hmm, looking at the picture of the 6400 riser, the two caps C1 and C2 are connected to these pins PRSNT1# and PRSNT2#. So not decoupling. Your cable kludge worked without these? Are they present on other 2 slot risers? I have a cheap ESR meter that should be able to find an approximate...

Let me know when you find them... Also, I think the capacitors are just for decoupling? If so capacitance value is not critical and can be assumed. Please check this. If they are decoupling then the anode (+) will be connected to Vcc and the cathode (-) goes to GND. Once this and the resistor...
