What is Douglas CAD/CAM Professional System?

This includes 3 applications from the Professional System for Circuit board layout and manufacturing software suite sold by Douglas Electronics in late 1980's:

• Schematic Designer 1.2
• Schematic Librarian 1.2
• Schematic Reporter 1.2

This is version 1.2.  It lets you build electronics schematics and even virtual tests in real time.  You can click logic doors and switches on the schematics to see how the current/voltage changes.  It can display some label colors too.

Included in the download is also the Professional Layout and Pen from the Douglas CAD/CAM system, version 5.2 from 1988.

The Douglas CAD/CAM Professional System is aimed at professional printed circuit board (PCB) designers. It is a fully integrated computer-aided design (CAD) and computer-aided manufacturing (CAM) system that, after four years of evolution, has overcome all the shortcomings of the original version.

The latest version is a complete package. With it you can capture an electronic schematic diagram, perform digital logic analysis on the circuit, and lay out the PCB manually or, using autorouting, plot the output and have prototype boards fabricated by Douglas.

You perform each operation in Douglas CAD/CAM Professional with a separate application program. You can buy all of the modules separately or all as a set. The company offers full credit on the lower-priced modules when you upgrade.

There are three primary CAD/CAM Professional programs: Schematic Designer, AutoRouter, and Professional Layout. Professional Layout contains two output programs: Professional Print and Professional Pen (for plotters). These are augmented by Douglas CAM Exchange, a communications program that allows you to send design layouts by modem to Douglas for manufacturing. With it you can receive price quotes and place orders for circuit boards.

You can design single-sided, double-sided, or multilayer PCBs up to 32 inches by 32 inches, using conventional assembly procedures or surface-mounted techniques. You can also design silk screens for markings and solder masks.

Compatibility notes

 

• Macintosh 512KE or later
• Two 800K floppy disk drives or hard disk drive recommended

This probably runs on any 68K or PPC Macintosh computer ever made.

It's tested and working in SheepShaver under Mac OS 9.0.4. 

Also works under BasiliskII with OS 8.1 or 7.0.1, and vMac with 6.0.8

 

Emulating this? It could probably run under: Basilisk II
