Availability:
OUT: headphones71.5x78.5x12.7mm (73.1x80.3x15.5mm max w/protrusions), Body only: 62g (89g w/batt)

Features: Panasonic's first MDLP unit. World record breaking 104 hour battery life. Power cut alarm signals "pi-pi-pi-pi" for 2 seconds, 3 times, before power goes out.

Announcement commentary: (courtesy Leon) Audio section has identical spec to all Panasonic portables since the MR200 (3.5+3.5mW, 2-step S-XBS). Size is identical to the earlier MJ80 (12.7mm thick). Like the MJ80, it is possible to attach a hand strap to the MJ78. The MJ78 also has "smart change" (draws in disc when the lid is pushed closed, and one-touch eject). It seems that the MJ78 doesn't come with the charging stand - the specs say you need a separate adaptor in order to use AC power.

User Comments: I've taken apart my Panasonic MJ30 and MJ75 and was able to dig up some info on the web about the chips I saw. On each of these units, there's a Sanyo chip set (decode-only ATRAC chip and "RF head amp", as listed on press releases), and a Panasonic chip (listed simply as microcomputer). The first Sanyo chip set documented online has ATRAC chip LC89640, and was announced in November 97. The set that has LC89641 was announced in September 98. While the older set consumes 120mW when in use, the newer set only consumes 46mW. These Sanyo chips all incorporate digital bass boost. However, they don't include the DRAM for shock-resistant purposes. Instead, they support external DRAMs. The MJ30 has the LC89641 set. The MJ75, meanwhile, has a LC89642 set. Info about the MJ75's chip was not found online, but it's probably another evolution. The specifications for the microcomputers have also been found. The MJ30 uses MN101C15C, which has RAM 2048(x8bit) and ROM 48K(x8bit). The MJ75 uses MN101C28D, which has RAM 2048(x8bit) and ROM 64K(x8bit). I'd like to mention that the MJ75 takes apart really nicely. Remove the screws that hold the bottom cabinet, then the unit can be split into three parts: bottom cabinet, chassis, top lid + disc holder. No small bits and pieces to worry about. The circuitry/mechanism is also uncluttered, almost elegant. -Leon

The Panasonic NiCd 1.2V 600mAh which came with the UK version of Panasonic SJMJ-75 and the Panasonic NiMH 1.2V 1400mAh that came with the Panasonic SJMJ-70 are compatible with the Sony MZ-R/E900. Both can be recharged on Sony's charger and vice versa. Sony's own NiMH 1.2V 1350mAh battery can be used on Panasonic models and charger. Jon Choo

Comments: The MJ5 has a matt finish front, similar to the Sony MZ-E30/E35. The MJ7 has a special finish, made by engraving many narrow concentric grooves (some frying pans have this circular groove design on their bottom), then coating it. However, having the MJ7 I wish I'd gone for the MJ5, as the coating is now a mass of scratches and dull patches (despite keeping the MJ7 in the protective neoprene bag). It looks like someone's been ice skating on it! The back of the MJ7 is the 'matt' style finish (same as the MJ5 I'd guess). -Martin Clinton
