Welcome to the IMSAI Vintage Microcomputers storefront and library. We produce high quality vintage microcomputer kits for the hobbyist market. We are very excited to offer many of the same systems, components, and parts that were available when IMSAI began in San Leandro, California in 1975. IMSAI’s original flagship product, the IMSAI 8080 (CAD rendering on the right) sold nearly 20,000 units from 1975 through 1979.

After a hiatus, IMSAI is back in business under new leadership. Our goal is to meticulously recreate the IMSAI products that were successful throughout their time in business. We will also add to the IMSAI catalog with new products in the original IMSAI tradition. They will be unmistakably IMSAI. Some will have a modern twist.

Update — Please Note!

As of 25-April, 2025, we have been hit with unforeseen delays from vendors and crazy tariffs being imposed on special order parts. This extreme level of uncertainty is making it almost impossible for us to publish stable anticipated pricing and availability. While this is affecting primarily the cabinets and backplane, it is having a ripple effect on everything. Because of this, I have temporarily suspended publishing pricing and availability of product that is not currently shipping. For those who have been watching this website lately, the “coming” prices and dates have been rather unstable.

I just wanted to explain why suddenly future pricing and availability have disappeared. It doesn’t mean that the products aren’t coming. It just reflects the extreme uncertainty we’re facing. I hope that these issues are resolved sooner than later. My heartfelt thanks for your continued interest in IMSAI and our efforts to bring back the legacy!
