IBM PS/2 (Model 65 SX) - Technical Specifications

General information
Machine type: 8565
Announce date: March 20, 1990

Excerpt from the original announcement letter;
"IBM introduces two new Micro Channel (TM) Architecture models based on the popular Intel TM 80386 SX processor, the IBM Personal System/2 Model 65 SX 8565-061 and the 8565-121. These floorstanding systems utilize the 80386SX processor running at a clock speed of 16MHz. Standard features include a 1.44MB, 3.5-inch, half-high diskette drive, VGA graphics and 2MB of memory on the system board. The fixed disk drive controller is the newly introduced Small Computer System Interface (SCSI), the PS/2 Micro Channel SCSI Adapter. This bus master adapter provides additional expansion capability while providing an interface for the new 3.5-inch, half-high SCSI fixed disk drives of either 60MB (8565-061) or 120MB (8565-121). Both models can be expanded to 8MB of memory on the system board and support up to 16MB of system memory. "
