Sharp MZ-1F11 Documentation
Sharp published an owner's instruction manual and a service manual supplement for the MZ-1F11 MZ Disk Drive, the external Quick Disk drive that it sold for the MZ-700, MZ-800, MZ-2000 and MZ-2200. Its drive is the same Mitsumi drive that is built into the Sharp MZ-1500, so these are the nearest Sharp documents to a service manual for the MZ-1500's drive.[1] Both are hosted as English scans from SharpMZ.net.
Instruction manual
[edit | edit source]File:Sharp MZ-1F11 Instruction Manual.pdf is Sharp's 15-page owner's instruction manual for the MZ-1F11. Its contents, with printed page numbers:[2]
| Section | Page |
|---|---|
| Cautions | before the contents |
| Parts of the disk drive | 1 |
| Connecting the MZ-1F11 to a computer (MZ-700 series with the MZ-1E14, MZ-800 with the MZ-1E19) | 2 |
| MZ disk: the 2.8-inch disk, inserting it, write-protect tabs, data read and write, disk protection | 3 to 5 |
| How to clean the disk head | 6 |
| Removing the bottom plate | 7 |
| Pin-out of connectors | 8 |
| Specifications | 9 |
| Circuit diagram | 10 |
The specifications give 64 KB per side on one spiral track, a disk life of 2,000 passes and a supply of +5 V ±5% at 300 mA average (1.5 W, rising to 5 W during a motor lock failure).[2]
Service manual supplement
[edit | edit source]File:Sharp MZ-1F11 Service Manual Supplement.pdf is Sharp's 8-page supplement to the MZ-1F11 service manual, code 00ZMZ1F11R//E. It applies from serial number SU000012, when the drive's SIO board gained a Quick Disk controller LSI and the head padding became an assembled pad unit.[3]
| Section | Page |
|---|---|
| Troubleshooting: deciding whether the MZ-1E14 interface or the MZ-1F11 is at fault; flow charts for a motor that does not run, write failure (write-protect error, not-ready error, data not readable after writing) and read failure; an SIO bus check program | 1 to 3 |
| Pad unit replacement procedure (pad life 18,000 passes) | 4 |
| QDC pin configuration | 4 |
| Circuit diagram | 5 |
| Parts position of the SIO board | 5 |
| Parts list for the SIO board | 6 |
What these documents do not contain
[edit | edit source]- The original MZ-1F11 service manual is not here. The supplement refers back to it for everything it does not change, including the off-track adjustment named in its read-failure chart.[3]
- There is no parts list for the drive mechanism or its control board, and no belt specification.
- Neither document mentions the MZ-1500 or the MZ-2000; the instruction manual describes connection to the MZ-700 series and the MZ-800 only.[2]
