The DPDT switch will allow me to switch the Gotek on and off, and when it is on the drive select signal will be routed to the Gotek, and when off it will be directed to the physical B drive. Then further Dupont ribbon cables take the signals into the floppy storage pocket to the Gotek drive.Įverything is removable, and in modular sections for easy disassembly of the machine in the future. Then I use Dupont ribbon cables (from a floppy plug) to take the signals I need to the front of the machine. The idea is I have a 34 pin floppy extension cable inside the machine, to intercept the existing floppy cable without cutting it. So I design this rather convoluted wiring diagram: That’s a nice round dozen – or two 6 pin cables that will happily fit through the slots! That’s just 11 pins :-) If I want to switch between the physical and emulated drives, I’ll need an extra line connected to a switch to send the drive select signal back to the physical drive.

A floppy cable would probably fit through if I doubled it up – but then I’d have to install plugs either end after feeding it through, making the cable fairly permanent (without cutting it). So next I investigate the ventilation slots at the back of the storage pockets: Ideally we’ll have a way of switching between the physical B drive and the emulated B drive. So let’s work on the idea of putting the Gotek in the right pocket, and have it emulate a B drive. The RS232 port is more central, but it would be a tight fit to get the floppy cable alongside the socket, and might stop me using the RS232 (which I will probably still want to use).Įither way, I don’t really want to use the left pocket, as it’s very hard to fold up the keyboard unless you tuck the keyboard cable in that slot! On the left side of the machine I could get a cable out of the IEEE 488 port, but then the cable would go diagonally up to the left storage pocket. But that would mean permanently removing the vertical bits of that grill, which I don’t want to do. I also eyed-up the ventilation slot just beneath the Gotek, as it’s the perfect width, and the cable would go up nicely through the indents designed to allow your fingers to grip the stored floppy disks. But then a light grey cable would snake its way up the outside of the machine. I measured one, and I could just get one through the hole of the “Ext Video” port (where it says “DO NOT REMOVE WHILE POWER IS ON” in the above photo). A typical 34 pin floppy cable is very wide.

The only problem was how to route cables to the floppy. I think this solution might fit the bill.

Ideally they shouldn’t change the aesthetic too much either. For something as rare as the Osborne any modifications had to be easily reversible.

I’m sometimes willing to make changes to retro equipment, but only to very common machines. I quite liked that idea, as it would let me keep a USB drive emulator in the Osborne case where it was easily accessible, but without needing to make any permanent changes to the Osborne. I discovered that if I removed the top of the case from the Gotek drive, it would fit quite nicely in one of the floppy disk storage slots on the Osborne: I had also wondered about leaving a floppy cable installed somewhere in the machine so I could attach a USB floppy emulator easily when I needed to, but it was in no way obvious how to do that without leaving the aesthetics of the machine a bit ‘messy’.

I’d already experimented with RS232 serial transfers.

In my last post I had successfully got a Gotek/FlashFloppy USB floppy emulator working with my Osborne computer.įor future use, I still wanted to design a way to copy any additional files as and when I needed.
