Manufacturer : NEC
Model number : PC-8801mkIISR model 30
Processor : μ PD780C-1 4 mhz
Memory : 64 kb
Drive : 2 5-inch floppy disk drives
Included : Keyboard, 3 terminal covers
With or without box : Body (without box / without box)
Special Instructions : The body and accessories are stained due to dirt and discoloration caused by burn marks.
There is a missing cover for the expansion slot on the back of the body, so the inside is visible.
When I checked the operation, the fan is louder than when I turned on the power.
Also, I am not sure whether it is caused by the body or the keyboard, but even if I connect the keyboard due to poor contact with the terminal, it is unstable because I can't recognize or input at all.
There was no other problem with basic operation.
The cover attached to the terminal had white powder due to deterioration, so it has been removed.
