Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.
This manual covers the main equipment features only. While it also includes the procedure for saving and loading from the now long obsolete memory cards it does not mention the how to operate with the optional floppy drive interface so I am still at a loss about how to use this! Note that there is a separate manual covering the MIDI interface and programming via the keyboard, not included in this download. You will also need to get hold of this if you want to use the MIDI interface properly. Basically there is little difference between this manual and the free to download manual for the similar PR60 model.
Good list of manuals. I found a very rare one and easily get. Should be promptly to download, as we must to wait hours even after confirmed payment.

The oven
ZDG 58
Baking trays and dishes For your safety
Never place cooking dishes, trays and so on over the oven burner. This will damage the oven as well as the ovenware and possibly the cabinet underneath the oven.
Leave a gap of 13mm (½") between all dishes and the sides of the oven so the heat can circulate properly. Do not push dishes too far back as food will burn if it overhangs the burner flames.
The baking tray we have supplied with your oven has been designed and tested to give the best results from your oven. If you use a tray or tin which is larger than this, you may need to turn it around during cooking. Place single dishes on the centre of the shelf. You may need to turn large items around during cooking.
Condensation
Condensation may form on the oven. This is quite normal and nothing to worry about. The condensation forms when heat and moisture are present, for example during cooking. Whenever possible try to make sure that food which contains a lot of moisture for example casseroles are covered. If you do notice any condensation, wipe it up straight away.
