    TashTwenty: Single-Chip DCD (Hard Disk 20) Interface

    I had the same issue; X says the INC file is missing (and indeed it was in my case). My experience with X was less than favorable, so I did exactly what you did and downgraded. Had no issue after that.

    Wow, you weren't kidding - Jan 2023 is the expected in-stock date at Mouser for the one I ordered originally. Glad I bought a few just in case I fried one.

    Well, fudge - I was hoping it was just me, lol. Either way, having HD20 access on a Classic or SE (even if limited to one "volume") is still incredibly valuable. I can't express how grateful I am that you got this running to where it is. With the FloppyEmu potentially no longer being available...

    Also, this is absolutely nuts, lol!

    Okay, sorry for the delay - it was a busy weekend. :( I ran the TashTwenty through the gamut of my Macs and can add the following: your assessment and mine of the 512K line up perfectly, so we're good there I had an identical experience with System 6 and earlier on my Plus, and also found...

    Good news everyone! All problems appear to be generally resolved now. The regulator (more on that below) appears to have absolutely been an issue; the flaky behavior on the Classic is gone and it recognizes and initializes cards (also more on that below) without complaint. It appears 50mA is...

    Nice! That thing truly is very tiny, lol!

    TashTwenty: Single-Chip DCD (Hard Disk 20) Interface

    Yep, powered by the PICKit; after doing some research, it seems PICKit 3's are hit or miss with internal power. I may try programming another with a jerry-rigged socket that uses a solid 5v external power supply driving the PIC. I also need to test this with the 866 and have the PICKit verify...

    TashTwenty: Single-Chip DCD (Hard Disk 20) Interface

    Okay, good-ish news (but PIC steps first)! When I selected the PIC16F1825 in the MPLAB IPE, it complained about not being able to recognize the device in the PICKit. I dropped the voltage from 5v to 3.125 and it immediately recognized it. I'm entirely unsure of how that worked, as I thought the...

    Hmm... then I'll probably avoid using an external supply. Out of curiosity, were there any steps getting the PIC flashed outside of just writing the HEX straight to it? Did it need any other control bits set or what have you? Just want to make sure I wrote the darn thing correctly. Grasping at...

    TashTwenty: Single-Chip DCD (Hard Disk 20) Interface

    @demik So, I did some thinking while I was looking things over (can't locate any faults, unfortunately), I got to thinking. Since I swapped out a 50mA 3.3v regulator for the original 250mA one, could that be failing to provide enough current to the SD card? If so, could I just wire up a 3.3v...

    Surely! Pardon the flux. I'll try another couple of SD cards just in case. Also, I have a logic probe if that's of any value, but sadly no scope. I've been meaning to get one and learn how to use it for a while now. I'll also double-check my work on the board while I'm at it.

    I've tested it on an SE and Classic running 7.0 and 7.1 respectively. I don't have an oscilloscope, unfortunately. :(

    TashTwenty: Single-Chip DCD (Hard Disk 20) Interface

    Alrighty - I got the PIC programmed (PICKit3) and formatted my card to (what I think are) correct specs aaand... nothing. The power LED lights up, but the activity LED does nothing; once into System 7, it doesn't appear to recognize that a disk is attached and in need of formatting. The series...

    TashTwenty: Single-Chip DCD (Hard Disk 20) Interface

    @tashtari @demik Almost done, but I'm not sure what J3 is for. The photo back on page four shows it bridged, but I can't find any reference to it in the readme. Does that need to be bridged for normal operation? Edit: D'oh! My bad - looks like it's just mislabeled as J1 in the readme down in...
