**Expert Report: Analysis of Vintage Computer Prices**

**Price Trends Over Time**

Our analysis reveals a general trend of decreasing prices for vintage computers over time. As more modern systems become available, demand and prices for older models tend to drop. This is reflected in the relatively low prices for early-era personal computers, such as the Tandy 200.

However, certain high-end or collectible items, like the Tandy 128K Color Computer 3, continue to command higher prices due to their rarity and demand among enthusiasts. These exceptions suggest that there are still pockets of interest in vintage computing, particularly for unique or highly sought-after models.

**General Assumptions about Products**

Based on our analysis, we make the following general assumptions:

1. **Condition is key**: The condition of a product significantly impacts its price. Items described as "working" or "tested" tend to sell for more than those labeled as "for parts" or "untested".
2. **Rarity and demand drive prices**: Products that are rare, collectible, or in high demand (e.g., Tandy 1000 TL/2) tend to sell for higher prices.
3. **Age is a factor**: Older products generally sell for lower prices due to decreased demand.

**Significant Outliers or Price Fluctuations**

Our analysis identifies the following significant outliers or price fluctuations:

1. **High-end sales**: The Tandy 128K Color Computer 3 sells for an unusually high price ($325) compared to similar listings.
2. **Price disparities**: Certain products, like the Tandy TRS-80 64K Color Computer 2, have identical prices despite differences in specifications or condition.

These findings suggest that there are still opportunities for collectors and enthusiasts to find unique and valuable vintage computer systems.
