ADAM Expansion Module #3 Memory Console with Wafer Drives - PROTOTYPE

A pre-production Expansion Module #3 memory console fitted with wafer drives rather than the digital data pack drives the shipped module carried. It dates from the period before Coleco settled the ADAM's storage, and is a development unit rather than anything a customer could buy.

LITTLE IS RECORDED about this machine outside collections. What the wafer drives were, how far the arrangement got and how many consoles were built this way all want confirming from the unit itself and from Coleco engineering material rather than from the general histories, which describe only the production system.
