No waiting for software ...This exciting micro has fired the imagination of programmers who are busy developping new software to take full advantage of its performance capabilities...
|
|
|
|
No wait state ...One advantage is the total elimination of memory access wait states so that interaction between the processor, RAM and disk drive is speeded up...
|
|
|
|
A free p-System for those who don't wait ...A free p-System operating system and PASCAL, FORTRAN 77 and BASIC compilers which alone lists for $1475, we're now including free with the Sage II...

text: I had one of these for a while. Nice machine, and astonishingly quick given its vintage. Distinctive feature - the CPU activity LED changed colour depending on whether the CPU was in user or system mode!

Sage Technology designed the Sage II around one of the fastest and most powerful chip available at the time, the Motorola MC68000, which was designed, among other things, for the implementation of high-level languages.
|
|
|
|
The Sage II, didn't look awesome. It was physically smaller than an Apple II, but packed a true 16 bits CPU and 512 KB of RAM. Only 128 KB were left free for the user, the remaining 384 KB being used as a RAM disc.
|
|
|
|
The Sage II used the **UCSD P-System** operating system. P-System means P-Code, an early universal intermediate code concept for programming languages, the same idea that Java is now based upon. Sage had even modified the P-System so that the system was truly multi-user. A special version of CP/M called **CP/M 68K** could also run on the Sage II.
|
|
|
|
One or two Mitsubishi 5.25 inch floppy drives were used to store programs and data. Each one could store up to 800 Kb per disk in the native Sage format. They were fully software configurable and had preset formats for IBM, Xerox, Rainbow and other systems. The only problem is that the Sage II didn't provide any hard disk management. This is will only be possible with the [Sage IV](/museum/sage-computer-technology-sage-iv/) model (10 to 40 MB hard disks).
