IBM Z® is a family of modern infrastructure that runs enterprise operating systems and IBM Z software, delivering advanced security, resiliency, performance, scalability and sustainability. Powered by the IBM Telum® processor, IBM z16™ enables AI inferencing at unprecedented speed and scale.

Cambridge Z88 (1987) Another notable computer was the 8-bit Cambridge Z88, designed by Clive Sinclair, introduced in 1988. About the size of an A4 sheet of paper as well, it ran on standard batteries, and contained basic spreadsheet, word processing, and communications programs.

RangerDisk2 gives users the benefit of handling large volumes of data without requiring a dedicated PC to act as host to the Z88. The combination of Z88 and RangerDisk2 can be regarded as a highly flexible alternative to the PC itself in many applications.

The Z88 was the final computer in the Z80 CPU "series" that Clive Sinclair created with the team of designers and engineers that also were famous for the ZX-80, ZX-81 and ZX Spectrum. The object of this project is to streamline the operating system, OZ and to build new applications by replacing the built-in ROM with a larger device.

z88dk is the only C and assembler development kit that comes ready out-of-the-box to create programs for over 100 z80-family (8080, 8085, gbz80, z80, z180, ez80_z80, KC160, Rabbit 2000, 3000, 4000, 5000) machines. The project was started in 1998/9 to allow a TCP stack for the Cambridge z88 to be easily written.

The Z88 is the most portable full-function computer ever devised, with a full sized silent keyboard, integrated display (8 lines x 80 characters) and yet being able to run for approximately 20 hours on 4xAA Alkaline batteries.

Comes complete with integrated set of powerful applications software: word-processing, spreadsheet, database, calculator, diary, calendar, clock, alarm, printer editor- all included in ROM. Can export, import and manipulate data from IBM- compatible PCs; converts its own applications software into Wordstar or Lotus 1-2-3 files.

The Z88 holds the honor of being the world's smallest laptop computer. It's the same size as a standard magazine, and not much fatter: 8 ½ by 11 inches and only an inch thick. And yet it is, in many ways, as powerful as a desktop computer.

Using plain old DOS commands on a PC, with a Z88 and a special serial cable, you can transfer files back and forth, print through the PC to a printer and replace the PC screen and keyboard by using the Z88 as a terminal to the PC.

There are two reasons for transfering files between a Z88 and another system. One is to backup Z88 files because permanent file storage on Z88 EPROMs is expensive. The other is to use the transfered data on the other system. These two reasons have been the driving force for the design of over 70 file transfer programs.
