PowerBook 160
Donor: Stern
The powerbook was introduced on October 19, 1992. It featured a 25 Mhz 68030 processor, 4 MB of RAM, and came with the option of 40, 80 or 120 MB of hard drive space. Also it came with a 1.44 MB floppy drive and a 640 x 400 pixel LCD. The screen was back lit by a cold cathode fluorescent lamp. The display supports 4-bit gray-scale but can support 8-bit color display on all Apple monitors up to 16 inches. This was the first power book to do so. It retailed at $2430. A few changes from the the older models were that the screen supports 1, 2, and 4 bit modes. Also the frame buffer was moved from $FE00 0000 to $6000 0000 and also occupies 128KB instead of 32KB. Another change was the display used a fixed device, instead of a color look up table(CLUT). This would effect software attempting to change the color table. This Powerbook also has a soft shut down feature. This means that that pressing the button the back would the same as manually shut the laptop off from the start menu.
Joyce Stern used this specific Powerbook 160. She is presently the “dean of student academic support and advising at Grinnell College”. The Powerbook was bought in late 1992 when she started at Lawrence University and the first computer she had ever owned. It died around 2000.
