TINA is Not Aida - it is a TOPS-20 system running on an emulated PDP-10 - a KLH10 model KN10-KL, 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 4 model B, with a 1.5 GHz ARM, 8 Gb memory, 32 Gb SDHC, and a Gigabit Ethernet interface, which it shares with three other KLH10 systems.
The emulated system cost about 1/10000 of the original, weighs about 1/60000, using 1/6000 of the power, and still runs about 25 times faster than the original system.
