WORK EXPERIENCE:

A total of 7 years of professional full-time computer programming experience:

Employed full-time by Odyssey Research Associates, Inc. of Ithaca, New York (from February, 1985 to June, 1986) as a software engineer and system administrator.

• Programming, testing, benchmarking, and documenting for the Air Force Nebula contract. The Nebula is a military standard computer (MIL-STD-1862B). The Nebula contract involved porting UNIX System V to the prototype Nebula computer located at Griffis Air Force Base, Rome, New York.
• Maintained a VAX-11/750 running VMS/EUNICE. EUNICE was the BSD UNIX utilities compiled to execute under the VMS operating system.

Employed full-time by Henry, Sheive, and Associates of Ithaca, New York (from September, 1983 to December, 1984) as a programmer writing programs to be compiled with the Pascal/MT+ compiler.

• Completed the firmware and documentation for the "ACT3", which was an intelligent cash register for cafeterias based on a Z-80 microprocessor, that could be connected to a host computer. It was implemented in the Pascal language without an operating system or BIOS in a very small amount of memory (64 kilobytes).
• A Pascal BCD (Binary Coded Decimal) math library was written from scratch for decimal fixed-point numerical calculations and display.

First job was at Ithaca Intersystems (from June, 1979 to June, 1983), employed full-time as a hardware technician with circuit board assembly experience and later as a programmer for their computer products.

• Successfully completed the Z-8000 CPU boot PROM monitor firmware and the Xenix Intelligent Serial I/O (ISIO) driver (Unix driver in C) and Z-80 assembly language firmware for the ISIO card for the Intersystems' DPS-8000.
• Successfully completed easy to use hardware diagnostic software, such as a fast and informative memory test written in assembly language, and a floppy disk controller exerciser written in Pascal, with its own test language.

Currently doing volunteer community service (from July, 1986 to present) to write "Mathomatic", which is a unique, free and open source, computer algebra system written entirely in C.

Also consulted and contracted to write programs in C and assembly language for the following United States companies, to their specifications:

• Ported a Unix editor to MS-DOS at Performance Software of Midlothian, Virginia.
• Wrote btree database software at Salient Technologies of Elmira, New York.
• Wrote Unix drivers and ported and debugged RISC boot monitor firmware at Ironics Inc. of Ithaca, New York.
• Wrote logic analyzer utilities for Array Analysis of Ithaca, New York.
