> These days you can get a similar spec (within approximately an order of magnitude) in an Arduino: 8,000 or 16,000 kHz with 32kB (rather than the 7090's 144kB) of RAM. That's 32K of flash memory, not general purpose RAM - the ATMega328 has only 2K of actual general purpose RAM (also, the ATMega series is also a mostly Harvard architecture - but I don't know what the 7090 was). If you wanted something closer to the 7090, the Arduino Mega (ATMega2560) with a RAM extension upgrade (because the 2560 only has 8k of RAM) would be a better comparison (if you wanted to stick with the Arduino microcontroller comparison).
