SYSTEM TECHNICAL MANUAL HARDWARE DESCRIPTION HARDWARE DESCRIPTION CONTROLLER MODULE The controller module consists of two printed circuit boards, the controller board and the graphics controller board. Two types of graphic controller boards are used: one, with 32Kbytes of RAM for systems with a monochrome CRT, the other, with 96 Kbytes of RAM for systems with color CRT.
Page 18
I/O Bus The lower part of the controller board contains the I/O bus to gether with seven user-accessible connectors. These connectors are identified on the board as J1 through J7 (reading from left to right), and correspond to the seven slots (numbers 1 through 7) at the rear of the cabinet.

BEDIENUNGSANLEITUNG LEISTUNGSERWEITERÜNGEN DAS STATUS-BYTE Ihr Programm kann das Status-Byte mit einer IN-Anweisung an Port 2 (31H bei IFSEL 2A) lesen. Abbildung 2.1 zeigt die Bedeutung der einzelnen Bits dieses Bytes. Bit: Abbildung 2.1: Das Status-Byte Dieses Bit wird nicht benutzt. Sobald der Maus-Adapter ein Interruptsignal ausgibt, wird dieses Bit gesetzt (logisch 1).

Die beim Einschalten automatisch eingestellten Werte (XMAX = 640, YMAX = 400) entsprechen einer angenehmen Reichweite bei der Benutzung einer Maus auf einem Schreibtisch.
Die Benutzung der Interrupt-Leistungen des Maus- Adapters (über die Abfrage des INT-Bits des Status-Bytes hinaus) setzt Erfahrung im Umgang mit Halbleiter-Bauteilen voraus.
