External Gotek on Amiga 500 with Drive-Selector Switch

Support Noel's Retro Lab on Patreon: / noelsretrolab
We set up a Commodore Amiga 500 my favorite way: With a Gotek (USB floppy-disk drive emulator) as an external drive, keeping the internal drive working, and with a drive-selector switch to toggle between DF0 and DF1 to make it possible to boot from the Gotek drive.
For this we start with an external floppy-disk drive and replace the drive with the Gotek. Then we need to add an adapter on the Even CIA to swap the DF0 and DF1 signals to allow the Amiga to boot from the external drive whenever we want to.

Hi Noel, you are actually wrong about needing an external drive! You can solder a floppy cable directly to a db23 (or modded db25) connector and this work fine for the gotek. If you are interested I can mail you the schematic, you can even 'steal' the 5v and ground from the db23 connector to power the gotek. I make these cables myself and use them for a gotek and a 3d printed housing and these look and work perfect.

[@NoelsRetroLab]

Really? And all of that while the internal floppy drive is also enabled? I'd love to find out more and give it a try!

[@patzik1910]

@@NoelsRetroLab Yes, the internal floppy also works, this is a copy/paste from Keirf's GitHub that refers to it, and I think also a link where you can buy the cables. It is however quite easy to build them yourself. How can I send you the schematic of the cable? One other nice feature I have installed is the kickstart switch from Keith, I am using one of the signals of the address lines to switch the bootselector (which I also installed). This way you not only have a switchless kickstart but also switchless bootselector :-) Replacing an external drive depends on the enclosure or cable being used. Amiga external drive enclosures usually include the circuitry to allow the Amiga to identify the presence of the drive. In this case the Gotek with S0 jumper is usually a straight swap for the old floppy drive. If using a passive cable such as this Ebay item then be aware that this identification circuitry is missing, but for arcane reasons identification will typically happen to work as long as the Gotek has an image mounted when the Amiga boots. If you are having problems with your drive being identified, seeForcing Drive Identification below.

[@gonzalo1972]

Hi Patrick. May you share more info on that cable schematic and 3d printing files for the external gotek?

[@patzik1910]

www.ianstedman.co.uk/Amiga/designs/Floppy_Adaptor_V2/External_drive_wiring_V2a.png Here you can find how to wire it up, I used a normal floppy idc cable and soldered the wires to a modified db25 so it will fit the db23. I cut 2 not used wires from the idc connector side and connected a power connector to these and soldered them to 5v and gnd on the db25 side.

[@jensvillebro9637]

Yes, this is a very important point that Patrick Kerkhof is making. As a user I can verify that the described setup works flawlessly, I use it on my Amiga 500 where the Gotek is connected to the external disk drive connector via a modified DB25 connector cable that also provides power. I bought the cable on ebay, it was cheap and easy. I think Noel is right about keeping these old systems as original as possible, so this is a really good solution. If you have the ACA500+ you can actually switch the boot select (DF0/DF1) in the start-up menu instead of installing a fysical switch.

Yes please! please make a complete video all the other steps that you ast if we would like to see in a new video, and please name all the specific partnames etz. regards

[@BokanoiD]

3:45 - Yes the port at the back of the drive allows you to chain another two drives to it, allowing for a total of four drives including the internal one. (DF0 to DF3)

[@NoelsRetroLab]

Right. That makes sense since a lot of the copy programs have the option for 4 drives but there's only one drive connector. Thanks for clearing that up.

[@RMCRetro]

I've tried chaining multiple goteks in cases in this way and it works just great

[@NoelsRetroLab]

Oh, neat! I didn't think about that. I assume each would need to have its own disk controller, right? What would be the main purpose of having multiple drives chained like that? Massive copying of disks, or would a game with multiple disks be smart enough to check all available drives for different disks?

[@heidirichter]

@@NoelsRetroLab It depends on the software. Some software only looks for DF0:, some only look for DF0: and DF1:, and some can and do use all 4 drives if you have them all connected. The main purpose was to reduce disk swapping, as many games would load something from say Disk 1, then Disk 4, than Disk 2. If you only had the one drive, obviously you'd have to swap each time it wanted a different disk, with two drives you'd only have to swap one disk (so in this case, eject Disk 1 and insert Disk 2, and if the game supported all 4 drives, you could just pop each disk in a drive and off you go.

[@regisdumoulin]

​@@NoelsRetroLabcontrary to an Ms DOS PC the Amiga always checks all drives for an inserted disk. Note the message says "Insert a disc in ANY drive". Back in the days I had an external disk drive and it was a breeze playing 2 floppies games

[@alexodis]

Ola Noel. Muito obrigado pelos teus videos, já aprendi muito com eles! I think installing a switch to the back of the amiga, to toggle df0 df1 ended up being a more intrusive mod than just taking the internal drive and replace it with the Gotek. The original drive would be carefully stowed in a drawer, ready to go back inside the amiga anytime you'd feel like having it back. Again, thank you very much for sharing your knowlege, I'm a subscriber and a fan. Greetings from Alhos Vedros, Portugal.

[@NoelsRetroLab]

I can see that. I really like having both the Gotek and the real drive functional, so for me it was worth the small modification, but I get why people wouldn't want to do that. There's probably a way to put the switch on the external drive with a minor cable. Heck, I wonder if the drive connection has an unused pin that could be used for this. Que bom que gostou dos videos :-)

Nice hack! The Amiga 1200 can boot directly from external drives, but they will never be interpreted as DF0:.

[@NoelsRetroLab]

I didn't know that. Booting from the external drive is the most important thing I wanted to achieve from this. Is there a drawback to having the external drive never being DF0? I can't think of anything.

[@oleurgast730]

@@NoelsRetroLab Many games assume the drive their are booted from is df0: So they start to boot, than access to df0: to load a file and fail. Simply a bad art of programming. Quite a big drawback... The CIA on the A1200 are PLCC44, not DIP. No socket, so no adapter. But of course, you have df0_select on the internal connector for the floppy drive and df1_select on the external connector. So cut the df1_select pin of the external drive connector and solder one wire to the pcb (to get df1_select) and one to the external connector (to put df0 or df1 select depending on switch position there). Also cut df0_select line on the internal floppy cable, sending the df0_select to the switch and the signal selected by the switch back to the internal drive.

[@johnseamons7455]

Great and very precise video. I am in the middle of purchasing a Gotek for the A500 . I want to also leave my internal drive as a floppy disk. I have been told that if I dont use the switch (DF0/DF1) to select the Gotek (External) I will not be able to boot from the Gotek. This also means the floppy drive will not show up, so I cannot copy disk from the floppy to the gotek using x-copy. If I want to copy from the floppy to the Gotek I need to ensure that the floppy boots first. This is using a supply cable, Not the one from an old external drive. What your thoughts on this. Is tht correct or will the cable from an old external drive work better ? Thanks

[@tetsujin_144]

10:42 ah yes the finest of dentistry games

[@ojkolsrud1]

My case doesn't have any holes in it, so I was thinking that I could put the switch behind the trap door somehow. It's useful to have the switch, if you ever need the internal to be DF0, but I can't imagine the need to switch it up that often if you have everything you need on the Gotek.

[@NoelsRetroLab]

Absolutely. 99% of the time you want the Gotek as DF0, so that seems totally reasonable.

[@davidef6621]

I'm using gotek fully external driver without the df selector i have not touch any internal part of amiga and since some of the games are not booting from DF1 the external drive (gotek) i'm using the usb of the gotek and then move to phisical floppy with X-copy so i can boot from df0 without doing anything to my amiga. Ofc you need to have some working amiga floppies but this is the solution to not touch anything of amiga.

My particular external drive (which shares a common form factor amongst many brands) has pin 1 on the opposite side so I had to twist my short ribbon cable to make it work.

Switching my external GoTek clone (from Simulant) is disabling the internal floppy drive. The vendor of your DF0/1 switcher actually says so, too.

[@NoelsRetroLab]

BokanoiD there at least 2 types of external drives. The ones that use a regular amiga floppy drive and the ones that use a regular pc drive with special circuits. The first ones work right away with the gotek, for the second ones you need to modify the circuit but I’m not 100% sure how.

All the DF0/DF1 switches I find on ebay say that the internal drive is disabled when DF0 is set to the external drive.

If the latter, could you point me to one that makes both drives available in both switch positions.

[@NoelsRetroLab]

That makes no sense. The switch is a really simple switch that moves a couple of signals around. It sends DF0 enable to DF1 and viceversa. So they must mean that when you have the switch on, BOOTING from the internal drive is disabled and you boot from the external one instead. But you're right, even the one I bought sais that. Weird! www.ebay.co.uk/itm/273053625803

[@thomasquemar969]

Inside an external floppy case there is a small circuitry that does two things : activate the motor only if required and identifying the drive type connected. Inside an amiga 500 there is also the circuitry to activate the motor but nothing for identifying the drive. This is no problem since the ROM assumes that DF0 is "double density" and always present. The problem happens when you logically swap DF0 and DF1 : the external drive become DF0 and works perfectly but the internal drive which should become DF1 isn't recognized since it lacks the identifying circuitry... Mods are possible but quite hard to carry out ;)

Good point. There's power to be had in the Amiga connector, but not in the Gotek data cable itself.

Can´t you simply use both drives internaly? There is so much space inside the A500... The backdoor is available at thingiverse. So without damaging the case of the A500 you might simply print a new trapdoor with a hole for a small USB drive like the Intenso Slim Line sticks to connect it there. Also a switch (of course a flat one). For display and push buttons print a smal "external" case. You only need a 6 wire connection (the buttons both use a signal and a GND, one of the OLED is also GND). You can route them inside the A500 out on the top (ventilation slots). Something like www.thingiverse.com/thing:2701629 , but the two buttons (or an encoder wheel) added. Of course you have to route the df1 select to the internal floppy connector (like it is from stock on A2000/3000/4000). But thats only one wire on the underside of the PCB. Of course you have to make a drive cable to connect both drives. As you have to make it yourself to connect both drives, you make the turn of df0 and df1 select in the cable (like it is done in A2000). It would be a completly reversible mod, no permanent modification - and much more comfortable than having always an external drive to connect.

Yes, I believe you could. The only thing is that you need the Gotek and a controller for it. Or at least so I thought. Someone told me it's not necessary, but I haven't confirmed that. In any case, yes, there's definitely space internally and that would be a lot more convenient than pulling out that brick of an external drive 😃

@@NoelsRetroLab Actually there seems to be much more interesting projects than a gotek. In 2013 there have been at least two projects to use a Raspberry Pi with a bunch of discrete parts for about $5 simulating an Amiga Floppy drive. At that time the Pi Zero W did not exist; I wonder if its possible to port that projects to it. It would be about 5$ more than a gotek - but transfering adf´s via wlan and selecting image to load via webbrowser would eliminate any need of case modding, as you use the sd of the pi and do not need swapping it arround to transfer data. It even emulates two floppys in parallel (if df1_sel is at the floppy cable like on A2000 A3000 or A4000, or added manualy to it). So using the Pi Floppy Emulation + internal drive would allow 3 floppys at the same time (if you also route df2_sel to internal cable). Have not gone into details of the projects now, only read summary articles. Edit: Sorry, now found out the Pi +5$ Hardware solution does not use an operating system on the pi, so no wlan available (but still an interesting solution) while the wlan version uses a pi and a SB HxC Floppy Emulator (>>100$), so out of range in price (and also cant write to image). But there might be an interesting alternative: It should be possible to use an ESP32 (or even ESP2866) in i2c-client mode to put the i2c output for the oled into a web-server. Also with up/down buttons using two I/O-pins it should be able to select images. So you can select images via smartphone and avoid button and display on the Amiga. Also there is a simple mod for making SD-Cards accessible via webdav using an esp (de.aliexpress.com/i/4001031573171.html). This in combination with SD->SD adapter (instead USB-Stick) might work to transfer adf between PC and gotek...

wtf...? nice video and neat work but.. what happened with "I wanna keep my hardware as close as possible to the original"? you even had to screw a hole on the amiga itself!

with ROM 3.x you do not need a switch

[@NoelsRetroLab]

Oh, I didn't know that! Do you switch with some key press or something like that? Where do you get that ROM?
