TINA is Not Aida - it is a TOPS-20 system running on an emulated PDP-10 - a KLH10 model KN10-KL, version 2.0h (with some additional patches), with 4MW memory, one RP07 disk, four RP06 disks, a TU45 tape drive, and an NIA20 network interface.
The emulator is running under
Raspbian Linux on a
Raspberry Pi model B, with a 700 MHz ARM, 512 Mb memory, 8 Gb SDHC,
and a 100MB/s Ethernet interface.
The emulated system cost about 1/20000 of the original, weighs about 1/60000, using 1/6000 of the power, and still runs about 3 times faster than the original system.
