Internal
The HD24 operates on a Nucleus embedded real-time operating system, running on a Motorola MCF5206 EFT54 processor, which combines a Coldfire processor core with several peripheral functions such as a DRAM controller, timers, parallel and serial interfaces.
A 26-pin port on the mainboard labelled 'Motorola BDM Port' permits background debugging using a Background Debug Mode interface adaptor.
There are two IC41LV16256 chips in the HD24: according to the data sheets, they are 256kx16 bit Dynamic RAM with EDO page mode, giving the HD24 a total of 1 megabyte of RAM.
The Ethernet chip is a CrystalLan CS8900A-CQ3, a 10BASE-T LAN chip.
For recording, the original HD24 uses 12 stereo Wavefront AL1101G A/D converters, and for playback it uses 12 stereo AL1201G D/A converters. The HD24XR model uses the higher-quality AKM 5393 A/D and AKM 4393 D/A converters.
The HD24 is equipped with an Analog Devices ADSP 21065L KS-264 digital signal processor. There is an ALTERA ACEX EP1K30QC208-2 FPGA (Field Programmable Gate Array) in there as well.
The HD24 little remote control (LRC) is almost identical to older ADAT LRC's. The buttons are labeled differently, but internally the remote controls are identical: a simple resistor network.

Famous quotes containing the word internal:
“I believe that there was a great age, a great epoch when man did not make war: previous to 2000 B.C. Then the self had not really become aware of itself, it had not separated itself off, the spirit was not yet born, so there was no internal conflict, and hence no permanent external conflict.”
—D.H. (David Herbert)
“The real essence, the internal qualities, and constitution of even the meanest object, is hid from our view; something there is in every drop of water, every grain of sand, which it is beyond the power of human understanding to fathom or comprehend. But it is evident ... that we are influenced by false principles to that degree as to mistrust our senses, and think we know nothing of those things which we perfectly comprehend.”
—George Berkeley (1685–1753)
“I have been amazed by the Anglo-Saxon’s lack of curiosity about the internal lives and emotions of the Negroes, and for that matter, any non-Anglo-Saxon peoples within our borders, above the class of unskilled labor.”
—Zora Neale Hurston (1891–1960)
