An enthusiast wrote software to mine Bitcoin on an old Toshiba T3200SX laptop running MS-DOS.
In C++, he wrote code to compute a custom Bitcoin block to test the device’s ability to process it.
The 1989-era computer is powered by an Intel 80386 CPU running at 16 MHz. During testing, the Toshiba T3200SX achieved a mining hash rate of 15 H/s with a power draw of about 39 W.
The developer claims that with these specs, mining the equivalent of $1 would take 584 million years. By comparison, the Raspberry Pi 4’s performance reaches up to 200,000 H/s.
He also tested the algorithm on a Toshiba T1100 Plus from 1986. The device, based on an 8086 CPU at 7.1 MHz, showed a hash rate of 3.6 H/s.
The mining programs for MS-DOS-era laptops were published by the enthusiast on his GitHub account.
As reported in March 2021, miners used a Game Boy to mine the first cryptocurrency. The system delivered a hash rate of 0.8 H/s.
