The name " blade server " appeared when a card included the processor, memory, I / O and non-volatile program storage ( flash memory or small hard disk ( s ) ).

It combines both the stream decoder for live programming and storage receiver for pre-recorded programming in one rack-mounted system, in previous comparison to separate units for live decoding and program storage respectively with the introduction of ContentDepot.

The Special Function Register ( SFR ) is the upper area of addressable memory, from address 0x80 to 0xFF . This area of memory cannot be used for data or program storage, but is instead a series of memory-mapped ports and registers.

Earlier revision Replica 1 came with an available Serial I / O card which allowed programs written on or for the Replica 1 to be stored on the hard drive of any common PC . This was needed because the Replica 1 had no other ready means of program storage, since cassette drives ( the Apple I's storage device ) are in short supply.

8051 variants may include built-in reset timers with brown-out detection, on-chip oscillators, self-programmable Flash ROM program memory, built-in external RAM, extra internal program storage, bootloader code in ROM, EEPROM non-volatile data storage, I�C, RTCs, extra counters and timers, in-circuit debugging facilities, more interrupt sources, extra power saving modes, more / less parallel ports etc . Intel manufactured a mask programmed version, 8052AH-BASIC, with a BASIC interpreter in ROM, capable of running user programs loaded into RAM.

When you feel you've mastered BASIC you can learn to give instructions directly to the processor instead of going through basic by using something called assembly language, which is natively supported on the 83 plus / SE and 84 plus / SE . Personally I never had much patience for ASM so I haven't published many things written in it, but you learn a lot about the real architecture of the thing and about embedded devices-for example, on a calculator, any given memory address is used for a single purpose ( whether it's holding the contrast level of the screen or for BASIC program storage ), something unheard of in higher-level applications like those on PCs.
