9200/9300

The UNIVAC 9000 series (9200, 9300, 9400, 9700) was a line of computers introduced by Sperry Rand in the mid-1960s to compete with the low end of the IBM System/360 series. The 9200 and 9300 (which differed only in CPU speed) implemented the same restricted 16-bit subset of the System/360 instruction set as the IBM 360/20.

The 9000 series used monolithic integrated circuits for logic and plated wire memory; the latter functioned somewhat like core memory but used a non-destructive read. Since the 9000 series was intended as direct competitors to IBM, they used 80-column cards and EBCDIC character encoding.

The UNIVAC 9200 was marketed as a functional replacement for the 1004 and as a direct competitor to the IBM 360/20. The printer-processor was one cabinet, the power supply and memory another and the card reader and optional card punch made an 'L' shaped configuration. Memory was 8 KB expandable to 32 KB.^[1] The 9200 II and 9300 II models, introduced in 1969, were extensions of the original 9200 and 9300 systems.^[3]

The printer differed from earlier UNIVAC printers, being similar to IBM's "bar printer" of the same era. It used an oscillating-type bar instead of the drums that had been used until this point, and ran at speeds up to 300 lines per minute.

This emulator implements the complete 9200/9300 instruction set, card reader, card punch, printer and Uniserver VIC tape drives. It includes the original Univac assembler, linker, RPG compiler and various utilities. A large selection of original Univac manuals are provided, including a three volume "teach yourself assembler" programmed instruction guide. It also includes a simple Windows based assembler that I wrote to allow me to debug the emulator. It has an integrated machine language debugger so you can debug any program that you may choose to write.

The blinking lights and switches on the maintenance panel have been implemented to the degree allowed by the available documentation. You can use the maintenance panel to manually enter your program into memory and single step through it just as you would have been able to do on an original 9200/9300.

This emulator was written by me, so if you have any questions or (heaven forbid) bugs to report you can contact me and I will do my best to help you.
