-Due to the individually different expansion of many QLs, we have designed the structure of a hard disk system with the HDD card as an "open solution", without a hard disk of a certain size, power supply unit and housing. This allows the experienced hobbyist in particular a significant cost saving compared to the finished complete system. Of course we can deliver all required parts, also ready to plug in. +Due to the individually different expansion of many QLs, we have designed the structure of a hard disk system with the HDD card as an "open solution", without a hard disk of a certain size, power supply unit and housing.

-The hard disk controller to be connected is already supplied with power from the QL via the HDD card If you are still using the original QL power supply, you must ensure that it is not overloaded (especially if there are other peripherals on the QL). If it warms up strongly and dark stripes move vertically across the screen, the power supply is overstrained and must be replaced by a stronger one.+ 
 +The hard disk controller to be connected is already supplied with power from the QL via the HDD card If you are still using the original QL power supply, you must ensure that it is not overloaded (especially if there are other peripherals on the QL). If it gets very hot and dark stripes move vertically across the screen, the power supply is overstrained and must be replaced by a stronger one. 
 For the hard disk an additional power supply with +5V and +12V DC voltage and the hard disk corresponding power design is required in any case. With QL systems, which were built into a PC housing with integrated power supply, this can usually also be used for the Winchester. A suitable housing for the hard disk drive is then already available here. Otherwise, you will need a sheet steel housing, with sufficient space for the additional power supply unit. For the hard disk an additional power supply with +5V and +12V DC voltage and the hard disk corresponding power design is required in any case.

 Due to its dimensions, however, the board cannot be connected directly to the system bus as the first board if the QL motherboard is (still) accommodated in the original housing. In practice, however, the two will hardly occur together. Due to its dimensions, however, the board cannot be connected directly to the system bus as the first board if the QL motherboard is (still) accommodated in the original housing.

-When using with other QL peripheral cards, note that an expansion slot is not used twice. 512K RAM extensions are always in the $40000 to $BFFFF address range and can never lead to conflicts.

 The addresses $10000, $14000 and $1COOO are not originally intended for extensions and are not checked by the standard QDOS so that the driver EPROM is not recognized. If you still want to use this address space (with the exception of the cases mentioned above), the Winchester driver must be explicitly included after system startup by the command CALL adresse+48, whereby the corresponding decimal value (65536, 81920 or 114688) must be used for address.
