DEC was not even that late, but so many came into the market. I worked a lot on DEC products (mainframe and mini) from 1974 for about 10 years.
DEC had a nice PC that seemed to debut not that long after IBM’s solidified as a thing, but other companies were also coming out with PCs, and DEC’s was expensive. I really thought it would take off. I was mad that it did not take off because I really liked DEC.
I got the DEC Rainbow PC. Used it for quite a while. I had a hard time imagining how I’d ever use the storage on the 300 MB hard drive. LOL.
