Development at least for the initial phase is almost done and I'll post the sources on github. The board piggybacks an inexpensive MCU dev board and looks like the first photo here. The first version of the PCB needed only minor "bodge" wires; the respin appears to work perfectly.
I've got mine in a nice box that will be tucked away in back of one of my tape drives. It looks like the second photo.
I've attached a sample log of dealing with a tape having 4 files. After reading the whole thing, I show how to read each file individually.
Hooked to a Fujitsu M2444AC drive, the controller can read a 6250 GCR tape at the full 75 ips. Writing takes about the same amount of time. Read errors are flagged in the .tap file.
Although I connected the STM32F4VE devboard using wire-wrap (easy to modify), I'll be replacing the wires with Dupont-terminated cables.
I want to compliment Mattis Lind for his fine job of PCB layout. The gerbers went to PCBway without a hitch.
