FWIW apparently mine is connected via a USB 2.0 hub to a USB 3.0 bus, but I've never had that underflow error.

Ah, brilliant! (I’m curious if your VR177x is happy with the Greaseweazel-written disk. Hopefully it’s fine but let me know how it goes!)

Cool, thanks, that bodes well! I’ve not actually used my home-made PlusD for a wee while so I’ve dug it out tonight to have a play with it. 😁

Brill, thanks. Let me know if you want to check out Beta DOS, I can share a prepared disk image with all the bug fixes and patches. A good source of interesting software is the old Outlet disk magazines. A deep vein of real nerd stuff, haha.

Yes sounds interesting. Do you know if there is a +d snapshot menu system ? I wrote a quick one in basic and it works ok.
