IBM PS/1

IBM PS/1

This IBM PS/1 system is working and in excellent cosmetic condition. Things to note:

This is the system box only, I do not have the monitor for this system, I powered it up for testing purposes with a bench power supply by inserting wires directly into the plug into which the monitor supplied power cable would normally go. Pinout I use for doing this is here: https://oldcomputer.info/pc/ps1_2121/index.htm a regular VGA monitor can then be used.

Keyboard is not included, I used a standard PS2 keyboard for testing which appeared to work just fine, I did not test the mouse port as I do not have a suitable mouse for it.

The 2.5" floppy drive is working fine.

The system seems to have all the standard PS/1 software installed, though I did not test it all extensively.

Also included is the PS/1 user manual and the Microsoft Works reference manual.
