Talk:PDB (Palm OS)

Several References state that PDB dates are offset from 1904. Some day offset from 1970 (same as unix). One states that "old files" may be offset from 1900. What should this article say? References (may need to be sited)?

PDB - Palm OS and Mac OS - October 2019[edit]

Question from User pinchies to User BrianFennell:

Hi Brian, I'm curious of the source of your information, "there were close links between Palm OS and Mac OS during early development" on the PDB (Palm OS) page. Could you expand a little on what you meant? Is that personal knowledge, or is there a source you would recommend I look into? I'm not aware of the history, but I'm interested in both Palm OS and Mac OS history. Thank you! pinchies (talk) 07:36, 12 October 2019 (UTC)[reply]

Pinchies - the documentation on the internals of Palm OS and its history are hard to track down. Much of the information is either in Copyrighted documentation which was released only to Developers who had paid for a Developer license (and occasionally leaked via a PDF here or there). Some of the information is "hear-say" - that is repeated by those with specialized personal knowledge or with access to non-public information on discussion forums, listservs, etc. I will try to find a reference-able source for the information about the connection between Mac development and Palm development. I believe that the statement is correct - but I do not recall a specific source at this time. It may have been a pattern of references that I noticed over many different sources, but I may be able to find a single source which is reference-able.

I wasn't able to find a single source - but basically: Mac Classic used Motorola 68000 cpus, and Palm devices used Motorolla 683xx cpus. Both had Metrowerks CodeWarrior for the officially supported development environment. The history of Metrowerks and CodeWarrior clearly show that the Mac developer community was the place of birth for that. You can look at the history of Mac OS Classic and Machines that used that OS and the history of Palm OS and the Devices that used that OS, also the history of Motorolla and Freescale and the 68000 chip set, and the following related Wikipedia pages: BrianFennell (talk) 22:46, 23 November 2019 (UTC)[reply]
