   Time to look inside a thing!
   I got this at the ewaste place a few weeks ago.

     It's a Dedicated Micros Eco4, apparently.
     As you can see from the buttons, this is some kind of security system device.

     The back. We've got a din-8 power supply, ethernet port, serial port, a db-15 alarm/relay port, then two sets (A/B) of BNC connectors.
     Mon, Vid1-4. Interesting.

     The bottom says it's specifically an Eco4 CD - 80GB, or a DM/ECO4C/80

     I don't have the power supply, but apparently it needs 5v, 12v, and -12v.

     I unplugged the cables. We've got HD, FAN1, and an unpopulated FAN2.

     Then the 40-pin IDE connector, and then KEYBOARD (which is the front panel), TTL DEBUG, JTAG, and TRST.

     That's why it's got 4 pins.

     It's reading about 1v now.

     And it plugs into this weird thing: The ST M48T35Y-70MH1
     That's a 32 kilobyte SRAM & realtime clock.

     They call this a SOIC28 but it has 32 pins, it's just that 4 are on top.

     I'm not sure what the max resolution is, but it seems like it's at least 720x480?

     IC12 and IC22 are both Sanyo LC82210LKs. These are JPEG/MJPEG encoder/decoders.
     They use external DRAM, and they're on the opposite side as IC66/67 half-megabyte chips, so those must be the ram chips for these.

     The other side of the keyboard. Little plastic buttons on a membrane. So it's slightly better than a remote control style keypad, but only by a tiny bit.
