Design Notes :

Shell Composition: Ultra-fine 3-D knitting incorporates knitted motors for full mobility surface, improved power handling circuitry.
Power Source and Energy Information: The armor ran on batteries and was able to recharge itself from electrical sources.
Weaponry: Monobeam: portable proton beam generator with a pulsed laser for ionized air conduit. Useful range about 275 feet; Palm Repulsor (Mark 1): laser-guided particle beam emission units mounted in the palm of each hand.
Equipment: Pacemaker; Boot Jets: second generation boot jets. Provided limited flight and it was the first to use a two-inch diameter turbine. Without the turbine in each boot, Iron Man would only be able to hover.; Jet-powered roller skates; Long-range AM/FM radio.

Notes: First attempt at anti-acceleration field; practical because of suit-wide electrical contacts. Armor's eye and mouth hole slits could be sealed as it had an oxygen supply for about 15 minutes.
