JC Wren had one with a load of other classic computers and the high bid was only about $2100! for a supposedly serial number 3 unit, run up by bidders from Switzerland, the US and finally the UK. It had been heavily modified internally, with even a hard disk inside. serial number) than a later unit that had all of the original MITS cards, motherboard and powersupply? My experience with car collectors (Corvettes), is that a unit in stock factory condition is more valuable than one that has been heavily modified. IMO ALL of the Altairs have been modified since they were sold only as kits. Yes you COULD buy assembled one but MITs still took a kit and just assembled it for you. To my knowledge none of them were build on an assembly line. Even MITs changed parts and revised the boards frequently so even the basic kits weren't all the same. On top of that, the user had to buy or build their own memory and I/O cards and the like (everything except the CPU card and chassis) so it's virtually certain that no two Altairs were identical even when they were new. And some mods such as a bus terminator were mandatory in order to make them work. Then considering that these were leading edge technology at the time and that they were constantly being hacked on and upgraded by their owners I would expect all of the surviving ones to be very different. I expect that 3rd party cards vs original MITs cards would detract from their value but not to the extend that 3rd party mods would to a collector's car. I suppose a better comparision would be a 1930s Duesenburg or some other car that were ALL build to order and no two were the same.
