The Sharp MZ 700 series replaced the aging MZ 80 (MZ 80K, MZ 80A and MZ 80B) series. Moreover, the MZ 700 was compatible with the MZ 80K and MZ 80A. The MZ 700 series is composed of four machines: the first three models were launched in 1983 (November 1982 in Japan) and the last one was launched in late 1985 (in fact, this one is the 'ancestor.

Sharp MZ-700 (MZ-711) Retro Computer good christma Hi, has been in a drawer for a few years. This item has not been used before and has not been opened. Details: sharp, computer, retro, christmas, idea, strting, exact, model, tape, ideal. Connection to the MZ-700 series: The MZ-700 must be opened. To this remove its screws: 5 screws at the rear, 3 at the bottom, 2 of the cassette recorder or the cover ( MZ-711 only ), 2 of the plotter ( MZ-731 only ) or the cover, 2 under the plotter and the recorder or the cover(s).

Perhaps you have so far been using a standard audio cassette player with your computer, or you may have been lucky enough to have load the data recorder supplied separately as a free ‘extra‘ when you purchased the computer. In either case, you will need to know how to connect up the data recorder.

Turn off the mains power to the computer and unplug the power cable.

Then turn the computer round so that you can reach the two cross-headed screws which hold the cassette compartment cover. Remove these carefully, using the right size of Philips-type screwdriver so that you don‘t damage the screwheads. You may find that a screwdriver with a suitable head size is rather small overall, making it difficult to get sufficient leverage if, as on my model ( was ;-), the screws are very tight. The answer is to get someone to steady the computer while you place the screwdriver into the head of the screw, pressing it in firmly, while you use a pair of pliers in your other hand to grip the shank of the screwdriver and effect the turning motion.

The following instructions are specific to the MZ-711, although owners of the MZ-811 will be able to glean general hints from them. Nowever, you will find that the MZ-800 Owners Manual shows the data recorder connections quite clearly in section 7.2.6 which covers fitting of the VRAM chips.

Having removed the cover, look into the compartment, which seems to be almost filled by a metal box ( the TV modulator ). You will see the jumper plug – a white connector with three short blue wires which come out of it and go back in again. lt is towards the rear of the computer – don‘t touch the connectors which contain several multi-coloured wires. Your task is to grip that connector gently but firmly and lift it upwards to remove it. lt is a tight fit, and you may find it helps to gently rock the connector from end to end ( but not across its narrowest axis, because that would bend the pins inside ).

When you have removed the connector store it away carefully ( together with the compartment cover ) as you would need it if you had to revert to a standard cassette player. Now look for a thin metal strip, with a row of projecting ‘teeth‘, which should be supplied with the data recorder. This is the earthing strip, and it is slipped over the two lugs into which the retaining screws are fitted, so that the ‘teeth‘ are uppermost and come into contact with the metal base of the data recorder when it is placed in position. Make sure that the tabs with holes in them are located between the metal lugs and the plastic of the outer casing, so they are firmly gripped when the screws are tightened.

Next locate the polarity switch. This is a black slide switch located inside the compartment, and changes the polarity of the recording head. On my computer it needed to be pushed to the right ( as you face the keyboard ) when being used with the integral data recorder, and to the left when used with an audio cassette. lf you subsequently find difficulties in loading programs try changing the position of this switch.

MZ-800 owners should ensure that system switch 4 is now in the 0FF position.

You will be relieved to learn that it is much easier to plug in the data recorder connector than it was to remove the jumper plug! Look at the 9-pin connector attached to the data recorder and you will see that at one side it projects downwards. This projection should be on the left as you face the keyboard. Place the connector gently on to the pins, and when you are sure that it is correctly located, press it firmly downwards into position.

Now lower the data recorder into its compartment, making sure that the connecting cable subsides gracefully into the space next to the connector, so that it will not get pinched between the data recorder and parts of the computer. Locate the screws and begin to tighten them. lf they do not seem to grip, check that the cable is not caught, then try again. Tighten the screws firmly ( so that they grip the earthing strip ) but not to excess.

Your Sharp MZ-711 / MZ-811 has now been transformed into a model 721 / 821, and you will now be able to follow the LOAD and SAVE procedures as outlined by the last 2 links and additional here.

For the MZ-700

Overview

This interface connects an MZ-700 series personal computer and the MZ-1F11 disk drive.

The interface reads the system software ( BASIC 5Z-008 etc. ) with built in IPL ROM.
( This takes about 8 seconds, not including AUTO RUN. )

BASIC text file ( program )Three types of files can be cataloged on a MZ disc:

  1. Sequential data
  2. Machine language ( system software, etc. )

Up to 32 files can be cataloged on one side of a disc ( the number of files equals to the number of programs or group data entries ). If only one program file is cataloged per side, the maximum storage capacity is 64 Kbytes. As the number of files increases, the storage capacity decreases. This is because a gap is required between files. Sequential data files are blocked in units of 1 Kbytes; the maximum storage capacity of a disc side is about 40Kbytes.

Parts of the interface

Connection

To connect the MZ disc drive to an MZ-700 series computer, perform the following.

Remove the data recorder, or the cover ( for MZ-711 or MZ-710 ).Turn off the power of the computer and unplug the AC cord. Remove the two screws holding the data recorder from the left rear side of the computer. Lift the data recorder out of its mounting. ( See picture below )
Remove the connector ( CN1 ) between the data recorder and the MZ-700 series computer.

When the data recorder is to be used, connect it to the MZ-1F11 connector (click here for details).

Install the MZ-1F11

Remove the bottom plate of the MZ-1F11 as follows:

  1. Unscrew the screws holding the bottom plate at the rear side.
  2. Remove the bottom plate in the direction indicated by the arrow.
  1. Connect CN2 ( from the bottom of MZ-1F11 ) to the connector of the computer main unit that was originally connected to the data recorder. ( See picture below )
  2. Mount the MZ-1F11 where the data recorder was originally, using the screws that held the data recorder in place.

Connecting the MZ-1E14 and the MZ-1F11 ( see picture above )

  1. Remove the cover for the external output terminal ( I/O bus ) at the back of the computer main unit by unscrewing the two screws for mounting the MZ-1F11.
  2. Plug CN5 of the MZ-1E14 into the external output terminal at the back of the computer and secure it with the two screws you just removed.
  3. Insert CN3 at the rear of the MZ-1F11 into CN4 of the MZ-1E14 and secure the connection using the screws originally securing CN3.

This completes connection of the MZ-1F11, the MZ-1E14 and the computer.

Connecting the data recorder ( see picture above )

The remover data recorder can be connected as an external unit to the computer as follows:

  1. Remove the cover for CN6 from the rear of the MZ-1F11, then insert CN1 from the bottom of the data recorder into CN6.
  2. Use the extension cable to be connected to CN1 and CN6, if you prefer more distance between the data recorder and the computer main unit.

This step completes the procedure. Switch on the power, and check operation.
