Well, I meant not that useful in the context of its time.
Considering how quickly CDROM drives spread to laptops and desktops, imho, this device never delivered on the potential of its promise.
PowerCD
is a computer, there's a teardown thread somewhere showing the amazing logic board in the base. I did the teardown and posted the thread to set the last nail in the coffin burying any mistaken notions that the DB-25 Player/Base interconnect was a SCSI connection. It's not, NEVER try to hook the player section up to a SCSI port.
Don't think you're looking at PowerCD's full feature set and its place within the development timeline of Optical Media.
Mine was built in 1993, 10 years after adoption of the CD for Music distribution. (SINGLE speed to this day!) PowerCD is a full fledged, standalone CD Player with remote control ready to hook up to an Amp/Receiver or even DeWalt's job site stereo radio/battery charger. [

It's a full featured, standalone Photo CD player, with remote control, capable of use interactively for presentations on TV or acting as a sequential or random photo display when coupled with a TV in a boardroom or living room. This was but one year after Kodak's introduction of the standard.
PowerCD s a full featured, standalone VCD (VideoCD) player. DVD didn't happen until 1995! Again there's that amazing (for its time) remote control. Check that lil' puppy out, looks a bit ahead of its time, right?
Oh yeah, there's that computer CD-ROM thing and Laptop adoption. That hit the PowerBook 5300 in mini form a couple of years later (Independence Day) and the 1400 in full form factor in 1996, three years after my PowerCD was first hooked up to my PowerBook 100.
Dunno, when did the first 2x CD mechanism appear on the landscape?
Getting back to that lovely PowerBook Gray appearance: that's a AA battery pack/computer logic board combo holding up the player section. No TV necessary for accessing all the features above from my PowerBook 100 or its Duo 230/SCSI MiniDock replacement. No AC Adapter required to set up a grayscale presentation on either. Used the 2300c/PowerCD to do standalone slideshows at industry get-togethers running off battery power wherever I wanted to set it down. Interactively remote controlled or just sitting there randomly displaying my Portfolio and pics form the last "Letterhead Meet." Of course I could have been using the 1400c I didn't get until about 2002, but anyone with any day one color capable PowerBook could have done the same.
'nuf said. [

addendum: found a bit of it:
PowerCD base unit REQUIRED!
Looks like the link for the full teardown there is to yet another of my many
Disappeared Threads. :-/
