Tandy 5000,
. That's 90's tech. My 1st computer was a TRS-80.
Note the cassette for mass storage. Although mine had the expansion interface and 8" Floppy disk too, which I think held about 120KB. The processor was a Z80. I think Dad paid around $2000 for it. 10 years later, I used a Z80 based "MicroProf" in labs at BCIT, which I think I paid about $150 for.
