The Sharp MZ-2200 is an 8-bit personal computer that Sharp announced in Japan in May 1983 as the successor to the Sharp MZ-2000. It runs the MZ-2000's software, but the keyboard unit no longer contains a monitor or cassette deck: the display and the MZ-1T02 data recorder are separate, and the graphics memory and expansion unit that were options on the MZ-2000 are built in.[1][2] It sold for 128,000 yen, against the MZ-2000's 218,000 yen.[1]
History
[edit | edit source]Sharp announced the MZ-2200 on 23 May 1983, with the slogan of a "component-type MZ" whose parts could be combined freely.[1] The Japanese Wikipedia article gives the release date as 17 July 1983.[2] The machine kept full software compatibility with the MZ-2000, so commercial MZ-2000 software and magazine listings ran unchanged, and both colour BASIC (MZ-1Z002) and the standard MZ-1Z001 BASIC came with it.[1] AKIBA PC Hotline describes it as Sharp's front-line machine until the Sharp MZ-2500 appeared in 1985.[1]
Hardware
[edit | edit source]The MZ-2200 is built around the MZ-2000's design. Sharp fitted as standard the equivalents of the MZ-2000's options: the MZ-1R01 graphics board, two MZ-1R02 graphics memory sets and the MZ-1U01 expansion unit.[1] The expansion unit lost the auxiliary power supply that the MZ-1U01 has, because the computer's own supply no longer had to power a monitor, and it is smaller as a result.[2] Sharp also changed the graphics memory refresh and the IPL ROM, whose messages differ from the MZ-2000's.[2] The floppy disk interface uses Fujitsu's MB8876 controller.[2]
The Japanese Wikipedia article describes three custom chips, the LZ90D01 CRT controller, the LZ90D02 memory controller and the LZ90D03 graphics memory controller, as made for the MZ-2200.[2] The same three part numbers already appear in the 1982 owner's manual of the MZ-2000, on its CPU board and graphics board.[3]
No scan of an MZ-2200 circuit diagram is known to be online. One owner, Ohishi, repaired an MZ-2000 by fitting a main board said to have come from an MZ-2200, after which it started and showed the IPL message.[5]
Connections and controls
[edit | edit source]- Front, in a pocket at the right: the RESET and IPL buttons and a volume slider.[1] The power lamp is also there.[2]
- Rear, from the left: the power switch, the power socket and the signal socket for the MZ-1T02 data recorder, the digital RGB output and the monochrome monitor output, with the expansion unit below.[1]
The MZ-1T02 is the only data recorder the MZ-2200 can use, and it works with no other computer. It takes its power from the MZ-2200 through a four-pin square plug and its signals through a 16-pin plug, so it has no mains lead of its own.[6] Its keys are rewind, fast forward, stop and eject, and it has READ and WRITE lamps.[6]
Known problems
[edit | edit source]- The MZ-1T02's pinch roller can melt with age.[6][2]
- The top of the case is not built to carry a CRT monitor, and the flat rear part of the top is a vent.[2][1]
Diagnosis and repair are covered in the guides below.
Documentation
[edit | edit source]Sharp printed the circuit diagrams of its MZ machines in their owner's manuals up to the MZ-2200, but no scan of the MZ-2200's own manual is known to be online.[7] The Sharp MZ-2000 Owner's Manual, with the full circuit diagrams of the closely related MZ-2000, is hosted with a description. A Sharp brochure page showing the MZ-2200 system and its peripherals is in the gallery below.
