I know this is an Apple based community, but I was wondering of the plausability of/interest in designing an Exidy Sorcerer replica (I think they are now as rare as or perhaps even rarer than the Apple 1). Somewhere around my house I have the complete set of schematics (I think its complete) for the Exidy Sorcerer. (Unfortunately the physical machine itself is long gone) Along with the schematics I have the original hardware and software manuals and a couple of cartridges (Basic and RAM) for this machine. Feel free to comment etc. etc.
While the Sorcerer is relatively rare, at least compared to the more popular computers of the era; like the TRS-80 and Apple II+, there is no way that it is anywhere near as rare as the Apple 1. Thousands of them were produced (versus about 200 for the Apple 1) and a significant percentage have survived. I have two of them myself, including my first "store-bought" computer, which I have owned since 1980.
They come up on eBay fairly regularly. In fact, there's one on there right now: http://www.ebay.com.au/itm/VINTAGE-EXIDY-SORCERER-II-COMPUTER-80x24-IN-BOX-RARE-COLLECTIBLE-/230741168838?pt=US_Vintage_Computers_Mainframes&hash=item35b93ed2c6
That one has been available for a while. They tend to sell for <$500 usually.
I doubt a replica would be practical. Firstly, because a real one is not that valuable. Secondly, unlike the Apple 1, the Sorcerer is more than a PCB. It would also require reproducing the case, keyboard, etc.
I'm not sure if it has already been done yet, but it would be a good candidate for an FPGA simulation.
