Hi all,
Just wanted to let you know that I have some early units of the next version of the PETdisk ready for testing.
Named PETdisk MAX after my toddler son. (He's named Max, not PETdisk in case you were wondering.)
Like the original, it's an SD card drive for the PET, and now includes a WiFi module to support using a standard webserver as a network drive for the PET.
I like using this function when doing PET software development - just build your program files to your development machine into a hosted directory, and then load straight from the PET, no SD card shenanigans required.
The new PETdisk does include a passthrough for use with other IEEE-488 devices, and is very low profile, doesn't stick out much from the back of the PET. It includes a connector for powering the device internally, using the 5v supply, which avoids the need for any external cabling. So hopefully this can be something you can just leave attached and use at your leisure. Has one SD socket, and also includes a connector which leads into the PET which you can use to connect a second SD card via an internal ribbon cable somewhere else. So you can mount something in a more convenient location on the machine if you wish.
For the internal power, I originally intended to use a pin on the memory expansion header, because for some reason I had it in my head that 5v was available on that connector - but it's not. So instead I laid out a small ROM passthrough board, which will go into one of your ROM sockets on the PET motherboard and provides a 5v pin to easily connect to the PETdisk. If you have an empty ROM socket, that's all you need, but if all your ROM sockets are full the passthrough board provides a socket to connect that ROM.
Still doing some improvements on the firmware, so there will be some frequent updates in the next couple of weeks. I have a few early units available now - if anyone is interested in helping with testing, I can send you one of these for just shipping cost.
Included a couple of pictures here, I hope to make a short demo video within the next couple of days as well. Here you can see the PETdisk max attached to the back of a PET with a debug/programming harness attached. Then the unit by itself.
Thanks for checking it out! Please let me know if you have any questions.
