I've heard some genuine horror stories regarding fax machines being used in software development in japan. A prime example was in the early 2000, circa 2003-04, when it was somewhat common for Japanese studios to outsource Game Boy Advance ports from arcade machines to smaller studios residing in Eastern and Southern Europe. A friend of mine was working in a studio tasked with porting several Irem (or Konami, can't remember) shooters. Despite communicating by normal means with the EU publisher and distributor, the contractual side was handled by fax, which they had specifically bought for this reason. Once the contract had been signed... nothing happened. That is, for all practical purposes they were expected to rebuild the game from scratch. They had zero support of communication from the original publisher and developer, Once they pointed out to the firm that it was an absolutely insane idea, and if at least they could ftpd them a snapshot of the original sources/assets, again all they got was radio silence. Then, after a week or two they started receiving... something, by fax. And by "something" I mean "printed and rescanned at 72DPI Black and White pages of partial Motorola 68K source code and artwork on grid paper fully in japanese". It was an obscene amount of useless, nearly unreadable data. Eventually they decided to ignore the original dev and got paid support from some MAME guys that basically helped them rev-eng the original roms. No idea how they were expected to send the finished game, I can only hope they didn't have to fax it back.
