IBM PS/2 (Model 35 SLC) - Technical Specifications

General information
Machine type: 8535-050, 055
Announce date: April, 1992

Excerpt from the original announcement letter;

"IBM is extending The Personal System/2 (R) (PS/2(R)) Model 35 SX family of systems by introducing the 8535 SLC. The PS/2 Model 35 SLC includes a 20MHz cached processor that provides up to 88% performance improvement above the 8535 SX. The processor includes 8K of internal cache, internal cache controller an improved instruction set and runs at zero wait states. Two model configurations are available. The 8535-050, 2.88 FDD with media sense and an open bay. The 8535-055 with 2.88MB FDD with media sense and an 80MB hardfile. "
