Seen on eBay for less than $600, a prototype of a Macintosh IIsi.
The Macintosh is non-functional, but it has some very specific features. First, it supports two NuBus expansion cards, whereas the base model only supports one (more precisely, the external slot is unavailable on the commercial model). It’s a DVT model with a motherboard that the seller claims is a PVT version, and it features a pre-production 68030 processor. Finally, the case is in poor condition, and there is no power supply or disk (or floppy disk) drive.
