The PLI utilities at Mac Driver Museum are for the earlier Syquest drives, alas.

I thought that I had broken my drive after cracking it open to take a few photos of the internals. I cracked it open again, ensured that everything was seated (the ROM is the only socketed DIP chip), twiddled about and it partially works again.

* The floppy mechanism is labelled Sony MP-F40W-1Y. It uses a 20 pin ribbon cable and has no supplementary power. It is an auto inject/eject drive. I have not compared physical size to a conventional 1.4MB mechanism.

* The physical ROM carries a paper label: "V1.4 PLI©NXT288".

* The board is silk screened "PLI Turbo Floppy".

* There is a square socketed chip next to the silk screen label that I cannot identify because the marks are so indistinct.

* Mac SCSI utilities identify the ROM as version 1.00. A couple of formatters have a go at formatting a 1.4MB floppy disk and the result is a 1.2MB not-especially-useful disk. I presume that the formatters are assuming block/sector/MFM parameters.

I have my own thoughts (about which I will be quiet initially) and welcome yours.
