Enthusiast wrote bitcoin mining software on an old Toshiba T3200SX laptop running on MS-DOS operating system.
In C++, he created code to calculate a custom bitcoin block to test the device’s ability to calculate it.
The 1989 computer is equipped with an Intel 80386 processor with a clock speed of 16 MHz. During testing, the mining performance of the Toshiba T3200SX was 15 H/s with a power consumption of 39 W.
The developer claims that with such characteristics, the extraction of the equivalent of $1 will take 584 million years. For comparison, the performance of the Raspberry Pi 4 microcomputer is up to 200,000 H/s.
He also tested the algorithm on a 1986 Toshiba T1100 Plus laptop. A device based on the 8086 CPU clocked at 7.1 MHz showed a performance of 3.6 H/s.
