  • Massbus Follies
    A Massbus Mystery, or, Why Primary Sources Matter, Even In Computer History Bob Supnik, 24-Sep-2004 Summary In preparing a simulator for the VAX-11/780, I discovered that all the extent printed documentation for the DEC RP04/RP05/RP06 controllers is incorrect. Further, VMS followed this error in its drivers, creating a latent bug that has been present since the first release of the operating system in 1977. Background: The Massbus The Massbus is a simple, 16b, high-speed interconnect between a CPU host adapter and one or more mass storage devices. DEC created the Massbus in the early 1970’s, to provide a CPU-to-mass-storage interconnect that was faster than the Unibus. The Massbus was implemented in the PDP-11/70 (via the RH70 host bus adapter) and the DECsystem-20 (via the RH20 host bus adapter). The Massbus was the primary storage interconnect on the VAX-11/780 (via the RH780 host bus adapter). Massbus storage could also be connected to Unibus PDP-11’s (via the RH11 host bus adapter). The Massbus implemented a very simple command and control structure between the host bus adapter and devices. The host adapter maintained the address and word count (DMA) logic. It communicated with the devices via register reads and writes. The host adapter mapped host addresses either to internal (adapter) registers offsets, or to external (device) register offsets. On the PDP-11, this mapping was quite complicated, and a mapping PROM was used between host addresses and register offsets; on the VAX, it was very simple, with different partitions of the adapter’s address space being used for internal offsets and external offsets.

Hệ nhị phân (Binary) 1.1. Khái niệm: Hệ nhị phân hay hệ đếm cơ số 2 chỉ có hai con số 0 và 1. Đó là hệ đếm dựa theo vị trí. Giá trị của một số bất kỳ nào đó tuỳ thuộc vào vị trí của nó. Các vị trí có trọng số bằng bậc luỹ thừa của cơ số 2. Chấm cơ số được gọi là chấm nhị phân trong hệ đếm cơ số 2. Mỗi một con số nhị phân được gọi là một bit (Binary digit). Bit ngoài cùng bên trái là bit có trọng số lớn nhất (MSB, Most Significant Bit) và bit ngoài cùng bên phải là bit có trọng số nhỏ nhất (LSB, Least Significant Bit) như dưới đây: 23 22 21 20 2-1 2-2 MSB 1 0 1 0 . 1 1 LSB Chấm nhị phân Số nhị phân (1010.11)2 có thể biểu diễn thành: 3 2 1 0 -1 -2 (1010.11)2 = 1*2 + 0*2 + 1*2 + 0*2 + 1*2 + 1*2 = (10.75)10. Chú ý: dùng dấu ngoặc đơn và chỉ số dưới để ký hiệu cơ số của hệ đếm. Đối với phần lẻ của các số thập phân, số lẻ được nhân với cơ số và số nhớ được ghi lại làm một số nhị phân.

  • A UNIX™ Operating System for the DEC VAX-11/780 Computer*
    A UNIX™ Operating System for the DEC VAX-11/780 Computer* Thomas B. London John F. Reiser ABSTRACT A UNIX operating system together with a complete user environment has been implemented on the VAX-11/780 computer manufactured by Digital Equipment Corpora- tion. The VAX-11/780 system provides 32-bit addresses and data. It uses the same input/output devices and the PDP-11 family and is controlled through a console computer which can be remotely accessed. Additionally, the VAX-11/780 is priced nearly the same as a PDP-11/70 and executes most programs somewhat faster than a PDP-11/780. This memorandum describes the VAX-11/780 hardware and the UNIX operating system and the C programming language software implementation, records some obser- vations on program portability, and speculates ways in which the operating system over- head can be significantly reduced. The authors conclude that the VAX-11/780 provides and excellent hardware environment for running UNIX and C software. Introduction The VAX-11/780 [1] is a new, general-purpose, stored-program electronic digital computer manufac- tured by Digital Equipment Corporation. At minicomputer prices it provides addresses and data which are 32 bits wide; the traditional minicomputer address space bound of 64K is gone. This memorandum describes the VAX-11/780 and the implementation of a UNIX operating system and complete user environ- ment for it. Section 2 contains an overview suitable for general consumption; details normally of interest only to devotees of computer system architecture appear in Section 3. The authors comment on software portability in Section 4.
