Yeah - I popped in this morning to have a look at it (well, that and to see if they had any SCSI cables - they don't

). Seems to be a kitset version, and the chap explained that the keyboard had extra extended function keys... yeah. I was curious on the off chance that it was a Super-80 mis-labelled.
Looks like it has two S100 interfaces. one with a card that looks to be a floppy controller? Is that normal?
He may post a pic of the other side. Turns out that if no-one had already bid, he may have sold it to me on the spot.
