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

[Tashtari]

So, I plan to do:
1. Format the SD card
2. Extract the image from the zipped file on above
3. Run the python script

Thus, I can have a SD card for my Macintosh 512K. Right?

The Python script helps you turn a raw Macintosh .dsk image (like those used with emulators like Mini vMac and Basilisk II) into an image that you can then write to your SD card and use with TashTwenty. You can get the .dsk image prepared on an emulator, then use the Python script to convert it to an SD card image, then use dd to write the image to the SD card, and use that card in your TashTwenty.

Okay, I will do it tomorrow. Thanks, pals!

The System 3.2 and 4.1 images I created for the FloppyEMU should work without modification

I just got a Mac 512k to experiment with

without modification

Unless they're made for TashTwenty, they will need to go through the Python script in order to add a MBR partition table.

So, you mean I can extract 410_2GB_drive.zip this file, and copy the content to the formatted SD card, it will be ready for everything?

Ah, if I remember correctly I initialized them on my Plus, I thought that would add the MBR. Will check

Try https://www.savagetaylor.com/wp-content/uploads/68k_Macintosh/Bootdisks/320_32MB_volume.zip. I initialized it on my Plus, and was able to boot using my FloppyEMU, what I don't know is if that added the MBR

I have used RUFUS in Windows 10 succesfully

Rufus - The Official Website (Download, New Releases)

Rufus is a small application that creates bootable USB drives, which can then be used to install or run Microsoft Windows, Linux or DOS. In just a few minutes, and with very few clicks, Rufus can help you run a new Operating System on your computer...

It didn't. What you have to understand is that the Floppy Emu and TashTwenty work very differently - the Floppy Emu allows the user to copy image files to a FAT filesystem, which you can then select using the display and buttons on the device. TashTwenty, by contrast, doesn't have a display or buttons - it works by using an SD card where the hard disk images (up to four) are prepared as partitions rather than files.

Ah, thanks. I can work with that, it would be similar to how I had to do a RAW write to an SD for SCSI2SD, or the partition setup option for the MacSD

So, what is the plan? I read so many messages.

1. Format the SD card by windows using FAT
2. Run the python script convert the file on above after I extract it.
3. Run the ETCHER to write the converted file to SD card

Thus, I can get the right SD card for Tash20 runs on Macintosh 512K?

You don't need to format the SD card using FAT, you're only going to overwrite it later. What I'd do is prepare a .dsk image with the desired version of the System/Finder using Mini vMac, then use the Python script to produce an image for the SD card, then use either dd or some other tool (I don't know what Etcher is, but it might work) to write the image produced by the Python script to the SD card.

• Make systemdisk.dsk using Mini vMac
• python3 makeimg.py sdcard.img systemdisk.dsk -
• dd if=sdcard.img of=/dev/sdc (but replace /dev/sdc with whatever the SD card device is)
  • Alternatively use Etcher or some other tool to write sdcard.img to the SD card

But, will the image file big enough? I am afraid I probably will install many other software in the future.

You can make systemdisk.dsk as big as you want.

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

i need one of these in my life.
