I would agree with the earlier dates (and Roger's comments). Maybe Eric could put a reasonable date on it. The Wikipedia article has several questionable statements in it. The guy who originally posted it is someone in Toronto that I don't know - but he has an "interesting" view of the structure of the company etc....
in 1978 I was involved in negotiations with Hitachi Corp. wherein they were interested in licensing SAPL - the work for MVS had been done, and we had even come to agreement on a price, but the deal breaker was that they wanted it running under TSO... They ended up implementing their own version under TSO and then we sold them some application systems in 1979. I have some interesting stories about all that, but I think they may be best left as "over a beer" stories... However, Xerox had an in-house system several years before that. Just that it, as did that version of the time sharing system run by IPSA, required a DOS System/360 rather than MVT or MFT - that is, pretty much a dedicated machine. By the late 70's most data centers had moved away from DOS. Maybe Catherine Lathwell can record some of these stories in her quest to document the early history of APL. I'll Bcc her on this message in case she doesn't lurk the j forums...

Catherine's blog entries are good reading and she is accumulating a lot of history. - joey At 22:04 -0400 2009/08/31, Devon McCormick wrote: >Joey - according to Wikipedia, Sharp APL was available as an "in-house" >product in 1980.
