You're not gonna get anywhere unless you bitbang HDLC or have a suitable USART (the S is the important part) on the Pi.  Let me say this one time because people seem to miss it: YOU CANNOT USE A NORMAL SERIAL PORT TO DRIVE LOCALTALK. You need a SYNCHRONOUS port, which uses clock signals for...

Hooooly crap, where'd you find that extension cable? This is very relevant to my hacking plans.

Yep, all SEs have a 50 pin SCSI header on the mobo. I assume the Molex is also in the wiring. It'd actually be cheaper for Apple to leave it in by reducing the number of wiring harnesses to stock.

Sure. Lop a molex off of a junk PSU and solder it to a +5 point on the AB. The extra power draw of the SCSI2SD is negligible, especially compared to hard disks from the day.

That depends on your definition of "put one in a Plus". You could hypothetically solder a ribbon cable onto the points used for the DB25 on the back panel...

D4164C is just NEC's model number for a 4164. If you're looking at 4164s, the letters before and after the 4164 part are vendor-specific information. It doesn't matter what it is, just that "4164" is in the name.

If you want my honest opinion, I would focus on taking an off-the-shelf Zynq board (I noticed Zynq was discussed before) and develop a NuBus/PDS "carrier card" to fit it on to. By doing this, you avoid all the difficulties involved with designing a Zynq board, for the most part. I should note...

Or SCSI2SD. I have never been a fan of Zip ever since the first one I had started eating disks in 2000. Too finicky.

Yes. You don't really need a buffer for this because the signals will be a static state, if you will. I would suggest using ground for low and a pull-up for high.

What he said. Although I might point out that 9 track is about as generic as SCSI tape drives get when it comes to compatibility- so it probably works with almost anything that supports tape.

That's not a resistor, that's a coil. Resistors are usually designated with R, not L. L is usually for coils (inductors, etc.) in terms of component designations. Plus your description matches with a coil more. Hopefully the wire is okay, because you're going to have a hell of a time replacing...

When you format a disk, it does a test for bad sectors, etc. Just because it appears to have worked in the past as a IIgs disk doesn't mean that; the Mac OS formatter may be much more strict about the disk. Your testing sample size is one. You have no way to determine if you just have a bad...

I'm up to my eyeballs in iPhone barcode scanner peripherals. Fun stuff. And every time I clean my house, I find yet another damn Bluetooth one.

Barcode scanner. Symbol SPT1550?

The power button color makes me think it's an IBM WorkPad, but I've never seen one with silver buttons like that. Much less a Palm III-form factor one with a rechargeable battery. Huh. I'm pretty stumped on this one.

Except that the 040 FPU is an incomplete implementation that relies on a bit of code from Motorola supplied with the OS to emulate the rest.

It wouldn't just confuse it, it does a checksum on the ROM and compares it to a supported list of ROMs.

Hell, might as well buy an IR thermometer, they're cheap these days.

New ROMs came this weekend, and it works! Now, what shall I fire up on this thing under 6.0.8?

Depends on which part of Durham- some of it is pretty sketchy, some is alright, some is pretty uppity. And then you have Duke students, which is a whole different level of scary in of itself... I live just south of Durham and do most of my shopping, etc. there. McDougle? I live just up the road...
