P8000

The P8000 is a microcomputer system developed in 1987 by the VEB Elektro-Apparate-Werke Berlin-Treptow „Friedrich Ebert“ (EAW) in the German Democratic Republic (DDR, East Germany).

The initial list price of the P8000 was 172,125 East German marks[1] (around 86,000–172,000 DM).

The processor, with a clock frequency of 4 MHz, was based on the U880 microprocessor (near clone of Zilog Z80) and peripheral circuits along with the U8272 floppy-disk controller.

Direct memory access was accomplished by U858 DMA controller chip.

In addition the computer had a parallel port which allowed the connection of an EPROM burner.

The processor operated at a clock frequency of 4 MHz and was based on the U8001 (Zilog Z8001 clone) 16-bit microprocessor .

A 6 KB static RAM served as a buffer between the host computer to the disk .

The WDC communicated with the host over an eight-bit-wide parallel interface in conjunction with additional control logic.

The interface handled transmission of data blocks plus the command and acknowledgment information.

In this system the Winchester disk controller and hard drive were contained within the housing of the host computer, eliminating the extra cabinet.
