Indeed :-). And I seem to rememebr all sorts of other wireless communication devices use versions of the AT command set. OK :-). I am not sure what I am going to use them for (the minidisk unit is playback only, I don't have anythign that could record such a disk, the hard-disk unit has a multi-pin connector on the bottom, I have no idea what the connections are), and I have no idea if they work. But tat thet price they're worth it for case parts, etc (they are in good physical condition). Incidnetally, for those who don't know what a Philips EL3586 is, it's a forerunner of the compact cassette recorder. The compact cassette origianlly used 2 track mono recording (heads record on half the width of the tame, flip the tape over to use the other half) at 1+7/8 ips. The EL3586 (and the older, and similar EL3585) is about the size of a large transistor radio and is a battery-operated reel-to-reel recorder (3" spools with the lid on, 4" with it off IIRC), using the same 'logical format'. I must compare the circuitry with that in the early cassette recorders sometime (yes, I have one and the service manual). -tony
