The IBM P75 has similar specifications to an IBM model 90, but has been made into a portable. It features an Intel i486-DX 33 CPU that is housed on a processor complex card separate from the motherboard.

This machine is one of the two so-called "luggable" models that IBM produced as a part of the PS/2 family. With the 8573-401 (P75) model you got a 486DX-33 CPU, onboard SCSI and four expansion slots.

P75 Information. The P75 can be described as a P70 on steroids. It boasts a redesigned planar with a i486DX-33 MHz CPU on a plug-in processor complex, as well as an embedded SCSI subsystem to replace the P70's direct ESDI attachment bus. Internal SCSI hard disk options were 160 MB and 400 MB.

With the Model P75, you can install sin­ gle modules. Two 4-MB SIMMs of 70-nanosecond DRAMs make up the system's standard 8 MB of memory. IBM offers both 2-MB ($565) and 4-MB ($1095) memory up­ grade modules to allow total system memory of 8, 10, 12, 14, or 16 MB. You can add more memory by way of a Micro Channel memory board.
