The PS/1 was IBM's return to the home computing market. It was the successor to the IBM PCjr, although it was compatible with IBM's bussines systems. The PS/1 was a propriatary system at first, but standard components were used later on. The later models included "Rapid Resume" a standby feature.
|
||
|
||
The system uses a LPX form factor (layout). Everything was built into the motherboard and had a four expansion slots of 16bit ISA but on a riser card. The memory was 72pin simms.
|
||
|
||
For the 486SX model for example, the CPU is integrated onto the motherboard but there is a socket3 that is empty. Apparently it is possible to put in another 486 CPU and the system disables the built-in CPU, which is not possible with the 386 model.
|
||
|
||
The software was Windows 3.1 and MS-DOS 6.2 on these systems. There is a bootloader from IBM that let you select ether to boot into DOS or Windows.
