The MicroVAX 3800 and MicroVAX 3900, code-named Mayfair III, were introduced in April 1989. [19] They were high-end models in the MicroVAX family, replacing the MicroVAX 3500 and MicroVAX 3600, and were intended to compete with the IBM AS/400.

This memorandum documents the DEC VAX (MicroVAX 3900) simulator. 1 Simulator Files To compile the VAX, you must define VM_VAX and USE_INT64 as part of the compilation command line. To enable extended file support (files greater than 2GB), you must define USE_ADDR64 as part of the command line as well. sim/ scp.h sim_console.h sim_defs.h

2017年6月6日 · SimH软件是配置用来仿真一个，64Mb内存，1.5Gb硬盘和一个CD-ROM光驱的MicroVAX 3900。 另外将需要一个包含OpenVMS安装媒体的ISO镜像文件，加载到虚拟光驱来启动仿真器。

The MicroVAX 3900 is the original model of VAX emulated by SIMH. (It now also emulates a VAX-11/780 .) It can run 4.3 BSD , VMS 5.1-1 to 7.3, and NetBSD , and OpenVMS 7.3 under Debian on a Tinkerboard.

DIGITAL VAX CLASSIC SYSTEM VIRTUALIZATION CHARON-VAX creates a virtual VAX environment on a standard Windows or Linux based host system. Stromasys customers can quickly, easily, and safely phase out aging and increasingly expensive DEC hardware, and replace it with an enterprise-grade virtual VAX environment on an industry-standard x86 platform.

VMS operating system on a VAX 4000 or MicroVAX, VAXstation, or VAXserver 3200, 3300/3400, 3500/3600, or 3800/3900 series computer. Document Structure This manual is organized as follows: • Chapter 1 describes some of the tasks you need to perform when you install the VMS operating system from a tape cartridge, magnetic tape, or compact disc.

VAXstation: II, 3600, 3900; Emulated systems can be configured with up to 512 MB of memory, subject to configuration constraints of the particular hardware model. Some emulated models may allow for more memory than can be configured on the original VAX system.

2016年10月1日 · layered product, DECwindows Motif for OpenVMS VAX. V1.2-3 is the minimum version of DECwindows Motif for OpenVMS VAX: that can be used with OpenVMS VAX V7.3. The DECwindows components provided in this kit requires approximately: 34400 blocks, broken down as follows: o DECwindows base support - 4400 blocks

A complete chart of the VAX processors and their instruction sets and system implementations can be found here. SimH supports two different VAX models: the VAX-11/780 and the MicroVAX 3900. The options for the VAX-11/780 are:
