LADDERS® 16-Bit

The invention of William R. Boyd—founder of WRB Associates, Inc.—this system was based on Digital Equipment Corporation (DEC) PDP-11 16-Bit Mini-Computers running the RT-11 OS, years before anyone had heard of an IBM PC. I founded MicroCODE in 1987 while still working at WRB with the encouragement of Bill and Joy Boyd.

LADDERS® 32-Bit

The 32-bit upgrade for WRB's PDP-11 system owners, this moved the LADDERS software from single-user PDP-11s to multi-user datacenter servers. This also introduced the CIMport PDS product, as well as the LADDERS Batch and Active Compare Report products. This product ran on the VAX/VMS hardware and operating system.

LADDERS® 64-Bit

This was the move to 64-Bit servers and workstations, years before Windows NT, decades before Windows would reach 64-Bit operating systems. This was made possible by DEC's Alpha-AXP hardware and OpenVMS OS.
