Now I need to buy a FloppyEmu to see if the passthrough port works. :) Or flash a floppy only firmware on the Fujinet.

Success! Was simply a bad PIC16F1704. Programmed a new one, did a little testing before swapping it in, and all better now.

But !CS you mean the !ENABLE line from the Mac? It's floating in this case and essentially low, so I would expect the Read LED to be lit since the RD line is also floating and low. I was just curious is you have an code to try to actively drive this lines that may have cause this blinking...

SCK always stays low, no activity at all. I see MOSI and CS pulse a bit at startup like they are trying to talk to the SD card, and then CS starts outputting that flash code after a few seconds. Programming with MPELAB X IPE v6.0 and a Chinese PICkit3. Using 20220621-1704.HEX from the latest...

Built up my new design, but no dice yet. Getting the 0000001 blink code (no SD card detected?) on startup. @tashtari, should Pin 10 on the PIC always be outputting a SPI clock signal, or does it stop once the SPI SD init fails and CS (pin 7) start outputting that blink code? I not seeing...

Cleaned up an dual drive 800K SE that came in a big lot today. Novy Systems "Magic" 25 MHz 68030 + FPU + 4MB RAM was hiding inside.

Did you ever do a validation build of your V2 design? Looking to throw a few boards on my next JLC order.

Been away from the Mac scene for a bit, but ran across this while working on the new Fujinet design. Nice work @tashtari Since my SmartPortSD with integrated DB19 connector fits so nicely on the back of a classic Mac, I did a quick respin of that design to turn it into a TashTwenty with an...

Sounds like a bad RTC chip or crystal.

Fixed!  Got my $2 for 10 KM4164 memory from China and had at it.  Piggy backing on F9 cleared the 0200?0 error, but then I got a 041101 (Mod3 test).  Piggybacking could clear that one, but when I actually replaced the chips, it cleared.  Ended up replacing four chips in total, all the Apple...

Picked up a chinese desoldering station a few years back. http://www.memotronics.com/vacuum-desoldering-rework-station-digital-temperature-controlled-dual-lcd-new/ Best money I ever spent on this hobby.  Make jobs like this infinitely easier than using a hand pump or braid.

Ya, I had already been through three cycles of flux, solder, braid, IPA scrub in that photo above.  Top pads and a few of the bottom ones cleaned up fine, it's just a couple of the really corroded ones nearest the cap being stubborn.

Thanks folks, new (used) memory is in the mail.

Since I need to wait on RAM chips for the 128K, I figured I would work on one of my extra nasty SE/30 boards.   LOTS of corrosion from the leaky caps.  No problem popping them off with the hot air station, pads cleaned up fine.  30 minute of vinegar and a toothbrush got most of the fuzzy off...

Finally getting around to fixing the 128K.  It chimes on startup, but then immediately goes to Sad Mac. Looks like a 0200?0 code, so I'm guessing memory in either F9, F10, F11, or F12 according to https://udcf.gla.ac.uk/~gwm1h/Error_Codes/Sad_Mac_Codes.html Any further hits given the video...

Went through most of the non-compact desktops pulling batteries.  So far it looks like exploding battery syndrome has only claimed a LCIII, IIcx, and IIci mainboard.  Maybe a Quadra 605, but that one still looks recoverable with a little work. Found a couple of Daystar's, a 68030 in one of...

Got a little over half the haul picked up this evening.  Even better than the computers is all the parts and other odd and ends this guy had.  Lots of new in box mainboards (including IIe boards), analog boards, power supplies, etc.  Need to head down tomorrow and grab the rest and then finish...

This is what I bought, was all one big lot.

My son really wanted the Apple III (notwithstanding the rodent activity).   The 128k, SE/30, and 840AV will also be nice additions to the collection.  Little spendy, but should be fun sorting and fixing for awhile. ...
