No, once you're in the blink code routine, there's nothing that should cause the SPI peripheral to output any signal... that's very strange.
This is also very strange. At the very least, you should see 80 clock pulses on the SCK line on startup.
*suspiciousness intensifies*
It should still go through the usual init routine, meaning it'll try to initialize the card and will jump into the blink code routine if it fails. If it succeeds in initializing the card, I'm not sure what it'll do because it might read the unconnected Phase/CA* pins as anything. I'm assuming the LED you're referring to is lit when the !CS pin is low... is the !CS pin constantly low, or does it go high for brief periods along the way?
No, I mean the chip select line to the memory card - my mistake, I thought that's where you had the LED connected. If you can, in future spins of the board, I'd recommend that you have a single LED connected to the !CS pin, that way users can see the blink code without using an oscilliscope. The read/write LEDs are somewhat inaccurate anyway because the Mac always has to do a "write" in order to read from the DCD, and likewise the DCD puts out a response that looks like a "read" for each sector when the Mac is writing to it.
Cool, that's a relief. =)
Looking good! You could also attach an actual-for-real floppy drive (an internal one, anyway), couldn't you?Now I need to buy a FloppyEmu to see if the passthrough port works.
The postal service transfers items to the Tashtari just fine... =D Seriously, though, last I heard, @Corgi was working on a tool along those lines, but that was in 2022 and they haven't been heard from since. CiderPress is an interesting prospect, though. If it doesn't have support for the images used by TashTwenty already, it seems like it'd be relatively easy to add it - if you ignore the custom icon support, TashTwenty's images are just standard MBR images with HFS partitions (type 0xAF).
TashTwenty recognizes cards with standard MBR (DOS) partition tables on them with HFS (type 0xAF) primary partitions. If you have a raw .dsk image that you want to convert into an image you can write to a card for use with TashTwenty, I made up a small Python script here that will do the job. Working with cards is currently easiest on Linux where you can just use fdisk to manipulate the partition table and then dd to/from the partitions... do you have a Linux machine (a Raspberry Pi works fine) available? I wish there was a simple GUI utility I could direct you to, but none exists that I'm aware of and I have very little experience in the area so I'm poorly positioned to write one myself...
Oh, good! I try to get it. And, I have a MacBook Pro M1 which is also a Linux like machine. Is MacBook Pro able to do the job?
You should be able to use the Python script, at least, and use dd to write an image to your card. I don't know very much about (modern) Mac OS, but perhaps others can chime in...
So, I plan to do:
