This is an aftermarket Atari 1040 ST internal power supply recently sold by Best Electronics. It works perfectly. It was acquired by a relative for a project but it was unfinished when I inherited their belongings. It may work on other models or other Atari computing devices, I don’t know.
You’ll need to solder the two input power wires to the spot indicated on the circuit board.
Shipped promptly USPS Priority Mail.
No returns.
