I had a hunch buying this floppy off eBay, and it paid off. The number rather dangerously scrawled on there with ball point is indeed a new driver version, previously unknown.
Version 3.5 Warp Speed light pen drivers and version 3.5 of their CONTROLLER shell.
The copyright date is also 1989, which is about when I figured they went kaput. Interestingly the driver does not say warp speed anymore, it says "Future Tech Software" and credits a Frank Taylor.
Clean flux dump.
