# TECHNICAL CHALLENGES AND WORK SUMMARY

The Welder Control Project presented unique technical challenges due to the vintage nature of the hardware involved.

Key Technical Challenges:

1. Legacy Hardware: The original controller used ISA bus cards from the 1990s, requiring specialized knowledge and equipment.

2. Driver Compatibility: Modern operating systems do not support legacy ISA cards, limiting virtualization options.

3. Hardware Failure: The original system experienced HDD failure, requiring data recovery from backup.

4. Incomplete Specifications: Tom never provided the complete technical specifications from MTI needed for full virtualization.

Work Performed:

1. Diagnostic analysis of failing original system

2. Sourcing and procurement of compatible replacement hardware

3. Physical integration of legacy cards into new system

4. Multiple attempts at virtualization using USB-to-ISA adapters

5. Data recovery and system restoration after HDD failure

6. Ongoing support and troubleshooting
