Introduction to the Kingston SLC/Now!
Cached Processor Upgrade Card
Congratulations on your purchase of the Kingston SLC/Now! Cached Processor Upgrade Card. This guide
will take you through the basic steps of physically installing and configuring the SLC/Now! into your PS/
2 system. This installation guide is written to provide a quick and easy process to install the SLC/Now!
processor upgrade. If you should require any assistance with this procedure, please feel free to contact
Kingston Technical Support at (800) 435-0640 (U.S. and Canada) or (714) 435-2639.
The SLC/Now! is a daughter-card upgrade that replaces the 80286 microprocessor in your IBM PS/2 Models
25-286, 30-286, 50, 50z, and 60 with a 386SLC or 486SLC2 processor. There are three models of upgrades
to meet every computing need: 386SLC-20 (20 MHz), 386SLC-25 (25 MHz), and 486SLC2-50 (50 MHz).
Designed by IBM for 100% compatibility, the SLC/Now! provides power and performance for today's most
demanding software applications and graphics-based operating systems.
Several important features of the SLC/Now! are:
Performance enhancement of 4-10 times over 80286 PS/2 processors.
20 MHz or 25 MHz 386SLC processor.
50 MHz 486SLC2 processor running internally at doubled clock rate.
Integrated 32-bit-wide 8KB cache and cache controller for "no-wait" processing for the SLC/Now!
20 and SLC/Now! 25.
Integrated 32-bit-wide 16KB cache and cache controller for the SLC/Now! 50.
Easy installation - simply plug the SLC/Now! into the 80286 socket of your IBM PS/2
25-286, 30-286, 50, 50z or 60.
Math coprocessor socket supplied on all models (supports 80387SX).
Allows you to maintain your investment in your IBM PS/2 at today's performance levels.
No need to reinstall or replace your application software, adapter cards or peripherals.
Add new applications requiring a more powerful 386 or higher processor.
The cache driver, supplied on the 3.5" diskette included with your upgrade package, allow you to enable the
onboard memory cache for superior system performance. Versions for DOS and OS/2 included.
For OS/2 installations, a 386 or higher processor is needed on PS/2 Models 50, 50z, or 60. This is
accomplished by adding the SLC/Now! processor upgrade. Be aware that,
OS/2 is NOT supported on the Model 25-286 or 30-286
even with an upgraded processor due to design limitations on those systems.
