That's most likely a VideoSpigot on that 2 PDS Slot adapter for use with a Spectrum 8•24(?) SuperMac IIsi VideoCard in the top PDS Slot for Display of the VidCap on a 13" CRT. If you're selling, I'm interested.
The other is likely a Hustler/Hurdler/Whatever from the folks that made the Hurdler(?) Parallel Port Card.
