What's a Sharp MZ?
While this portion of my website is dedicated to the MZ-2500. We need to know a bit of history in order to get a better understanding. Citations are located at the bottom of the page.
The "MZ" portion is commonly associated with the processor, the Zilog Z80B, hence the name "Microcomputer Z80B." The name is actually originated from a much older, 4-bit microcomputer kit, called the MZ-40k aka The Microcomputer Doctor.
The Sharp MZ-2500 was released exclusively in Japan on 1985, it was the final and most powerful model for the 8-bit series. It was succeeded by the 16-bit computer, MZ-2861. The MZ-2500 was known as the "Super MZ," because its CPU can go up to 6mHz, compared to the previous models that ran 2-4mHz. Its memory (RAM) is 128kb and can be expanded to 256kb. It can emulate older models like the MZ-2000 and MZ-80b, which is done by switching to said modes, making this the most compatible MZ model ever released.
The MZ-2500 has five different computer models:
- - Sharp MZ-2500
The most common model.
- Sharp MZ-2511Variation that comes with one 640kb, 3.5 inch floppy drive.
- Sharp MZ-2520Meant to be a cheaper option to an already expensive computer. Removes the tape drive, and 2000/80b compatibility modes. It was the first MZ-2500 model to come with a built-in dictionary ROM.
- Sharp MZ-2521Variation that comes with two 640kb, 3.5 inch floppy drives.
- Sharp MZ-2531Known as the SuperMZ V2, the most powerful variation. Comes with a tape drive for recording, two 640kb floppy drives, optional dictionary ROM, expanded main memory and TV video integration.
