This is similar  to a CF7, but use SD card and has nothing to do with CF7.

It allows a TI-99/4a to use disk image volumes on SD card as floppies.

I started this a couple years ago and have decided to share it in case someone else wants to build one.

Very cool project.  I checked out the Kicad project and there does not seem to be a created PCB file (just a blank one).  Did you ever get one tooled or have gerbers for the is project already?

There is no PCB and I don't intend to make one.

I built this using wire wrap for myself.

I never know when I will make a change.

 

If someone wants a PCB, They can use KICAD to make one.

I wished I would have used Eagle, Because Eagle is now part of Fusion 360.

In which case I could have milled a PCB on my CNC.

 

This ATMEGA162 emulates the disk controller and interfaces to the TI DSR rom.

I've got two Bunyan and two Fetzer protoboards. I may take one and do this and the Nouspikel USB, both of them, on it, for the peb box.

Nice! I use wire wrap too

 

So this acts like a drive attached to the TI controller? Or do you mean it has its own DSR ROM replaces the need for a controller?

It uses the TI DSR rom. I wanted it that way so it would be total compatible.
