I am building a replica of the Busicom 141-PF printing calculator. It used a variant of the Seiko/Epson EP-101 mini-printer, the Model 102. Does anyone which products used these early "drum printers"? By drum printer I mean where there is a continually spinning metal drum behind the paper and a series of hammers in front of the ribbon. Ideally I would like to get a working printer that is compatible with the Busicom calculator, but I will settle for a working calculator that I can adapt and/or reverse-engineer. Any advice would be appreciated.
