Re: [EXTERNAL] Re: Translating a DEVTYPE from LISTC into something usable?
Back in the olden days we were kinda pushed into new technology trying to get any angle we could for VSCR with software and hardware. One of the items was speed matching buffers in 3380 control unit. Everything went fine in testing. Then someone added a pack to JES3 spool. Blam! When I got in the PSR was just dog cussing one of the developers. Evidently there was no SMB controllers in JES3 development and they had a fall thru lookup followed by a DC X'00'. In a message dated 9/22/2016 2:13:54 P.M.

Some other trivia about DEVTYPE in catalog entries... The first two bytes are "feature" bits. For modern disk, it will always be x'3010'. These bits represent obsolete and now-standard functions that were once features, namely burst mode (obsolete), data chaining (now standard), and rotational position sensing (now both standard *and* obsolete!). The next byte is the device class, x'20' for direct access. The last byte, represents the device, and as others have posted x'0F' is set for 3390.

John - thank you I gathered the 3010 for dasd and it appears that tape is a bit more challenging (32, 33, 34, and 78) for the 1st 2 chars and the last 4 depend on the tape device. Is there a reference for these numbers - I recall there was at one time but that was in the last century. -- Lionel B.
