The document outlines several milestones and accomplishments in the person's career developing computer systems and components. They developed new methods for detecting microcode memory failures, designed performance monitoring and communication systems, completed software for a communications project, designed a data acquisition system for racing, and developed models and systems for disk drive validation. Their work resulted in several patents and positions at companies, and they now operate their own consulting business.

1. Milestones
Achieved

2. Computer system production was stopped. No
one had a method of detecting intermittent
microcode memory failures.
I developed a new method for detecting the failures.
My hand-built design, successfully restored global
production.
I was awarded four patents:
– 4,510,603 Testing system for reliable access times in ROM semiconductor
memories
– 4,379,265 Dual clocking time delay generation circuit
– 4,430,735 Apparatus and technique for testing IC memories
– 4,429,389 Test pattern address generator

3. A marketing group was unable to find a
performance monitoring system that met
their requirements and offered me an
R&D position to develop one.
Accepted the position and
developed a performance
measurement system.
It identified system
bottlenecks, and ways to boost
computer performance with
system upgrades.
Used to boost sales of
computer equipment in the
USA and Canada.

4. A communication system manager quit.
I was asked to save the failed project.
A re-designed system exceeded specifications.
My group met almost impossible deadlines.
Patents awarded:
4,514,824 Byte-oriented line adapter system
4,456,970 Interrupt system for peripheral controller
4,507,732 I/O subsystem using slow devices
4,430,710 Subsystem controller
4,428,043 Data communications network
4,379,328 Linear sequencing microprocessor facilitating
4,374,418 Linear microsequencer unit cooperating with microprocessor system having
dual modes
4,374,416 Linear sequencing microprocessor having word and byte handling
4,371,931 Linear micro-sequencer for micro-processor system utilizing specialized
instruction format
4,301,505 Microprocessor having word and byte handling
4,293,909 Digital system for data transfer using universal input-output microprocessor
4,292,667 Microprocessor system facilitating repetition of instructions
4,291,372 Microprocessor system with specialized instruction format
4,290,106 Microprocessor system with source address selection
4,287,560 Dual mode microprocessor system

5. An immediate need existed for
a low cost communications
system
Developed a high-speed
“C” firmware architecture
to run four high speed lines
on an existing, low cost,
board.

6. After developing a hardware/firmware prototype, my
software partner was late, so were losing our contract.
• Dissolved my partnership and completed the software myself.
• Offered the entire project, at half the cost, from RDC Enterprises (my
consulting company).
• The product resulted in a power measurement patent:
– 4,713,608 Apparatus for providing cost efficient power
measurement
• The product did well, and the company was purchased by a large
competitor, 5 years later.
Power Control and Environmental Monitoring System

7. Team Cotter Racing needed a better data
acquisition system
Having experience designing data
acquisition systems, and a
fascination with Indy race cars,
I volunteered to develop a system
to meet their requirements
Developed the data acquisition system
prototype, and a new company was
founded to manufacture and sell it.

8. Edge Racing
RDC Enterprises designed system upgrades
and new peripherals for the Edge product
line for over ten years.

9. Validation of a drive controller, requires an
accurate, adjustable, timing model for the
rotating media.
None existed.
Developed a model, using FPGAs,
memory devices, and host automation
software.
It produced timings that matched the
product design requirements.
The model resulted in the awards on
the next slide.

10. Award from Infineon, for successful
validation of the first Xbox drive controller
(0 Defects)
Patent awarded:
#7,031,902

11. As a victim of the latest recession, I was
frustrated during job interviews, when told I
was “overqualified”.
Nobody had a problem with me being “overqualified” when I was
a consultant, and owner of RDC Enterprises.
So, it was time to start a new consulting business:
Received 2 awards from the Who’s Who Registry, because of my
numerous computer design patents, (next Slide).
Another patent was granted:
7,800,856 Disk Drive flushing write cache to reserved tracks
during a power failure

12. Who’s Who Honors:
Lifetime Honorary Member Featured Member in the Registry
and on the Web Site

13. Is seeking more milestones
