With the imminent release of Mytekcontrol’s 1088XEL project I have decided to reimage the SDrive and XF551 floppy disk drive boards to allow an in case storage medium. Depending on your preference you can purchase an SDriveXEL for floppy disk emulation only or go almost totally retro with a real modernized XF551 floppy disk drive pcb that will drive a compatible 3 1/2″ or 5 1/4″ drive mech. There’s even an option to combine both SDrive and XF551 features on a single 4 layer pcb. For the die-hard DIYer there’s even the option to buy the bare boards and build from the ground up.
Your choice of mini-ITX case will be crucial as not all will have the required disk drive bays. The SDriveXEL option only requires a single 3 1/2″ or 5 1/4″ drive bay with adapter rails. The XF551XEL options all require both a 3 1/2″ and a 5 1/4″ drive bay or (2) 5 1/4″ drive bays in the case. I have listed some compatible cases below. By no means is this list exhaustive, but it gives an idea of what is needed. MicroATX cases that also handle mini-ITX boards are also an option.
Another crucial requirement is an adequate power supply to support the real 3 1/2″ or 5 1/4″ drive mech. I recommend an actual ATX12V standard pc power supply. A 200-300W power supply should be more than sufficient. No need to go higher. I have created a ATX12V adapter board to ease the use with the 1088XEL motherboard. It should work for either a 20 or 24 pin mainboard connector.
In other news….. the 1090XLR project continues in fits and starts. Currently the main prototype board and a serial/parallel I/O plug in board are in testing. I hope to begin testing Ralf David’s ROMDISK board soon as well.
