An Amdahl 470V/6 processor module
A 1975 mainframe module with wiring to give an engineer nightmares.
A processor module from the 1975 Amdahl 470V/6 mainframe. Gene Amdahl first designed System/360, then left IBM and launched his own line of compatible machines that were cheaper and faster.
How did they debug faults with wiring like that? An engineer's nightmare.
Modules occasionally turn up on eBay for around $1,000.
