Atari 1050/XF551 remote drive selector and LED display

macsonny · June 5

Hi All,

A few of you may have seen I've put a 3.5" and 5.25" drive using @Dropcheck's boards into an external case. It's really running nice.

I'm a bit annoyed every time I have to change the drive ID so I was thinking I'd just make something I could put on the front of the case that would have an UP and DOWN button and a display to show the DRIVE ID number selected. I was thinking an Ardunio board would be a good driver as relatively easy to program and maybe a display like this that can be customised to show the drive ID for each drive and also has built in control buttons: https://www.jaycar.com.au/duinotech-arduino-compatible-2-x-16-lcd-screen-display-with-controller/p/XC4454

I'm just wondering if anyone has done something like this in the past. I know @Dropcheck designed a remote control/display for her controller boards, but I was thinking I could design/build something more generic that woud effectively solder to the points on the exiting 1050/XF551 drive selector points and be independent of the controller board.

Anything done something like this in the past?

It will get a little complicated, not something a simple on-on switch could handle. You're most likely looking at a completely separate logic board to handle always on signals coming from each XF551 board to a single drive select toggle and ID display. I suppose it could be done with an Arduino board, but I've not heard of a project like that. I do know of a single drive id display project here . It's in Polish, but Google translator should work. But you'd have to add circuitry to handle a dual drive input.

Alternately fully populate the optional circuitry on the XF551 boards, assemble the optional control and display boards for each drive and then find a space on your case to mount them.

Sounds like a fun project I am assuming you trying to fit the display in one of the empty 5.25" Drive bay.

Chri O. · June 6

This OLED 2.42" display looks way better not sure about fitment in one drive bay ?

LINK: amazon.com

Drive bays are 1+5⁄8 inches (41.3 mm) high by 5+3⁄4 inches (146.1 mm) wide.

For buttons there is several options available just Google search for (Button Switch Module).

You may try to adapt a SCSI ID switch. These were common on external SCSI boxes 30 years ago. These are much smaller than an LCD display and are not powered.

Here is a project from 2013 for my Linux MythTV server 😃

Thanks for the links @Dropcheck. They are exactly what I need to build up. FOr all my skills of building electronics I’m hopeless with taking a schematic through to a PCB. Is anyone here skilled enough to turn the schematic into a PCB that I can get build up at PCBWay? I’m willing to send a few $$$ to cover people’s time?

Chri O. · June 11

Instead of trying to build PCB which can get expensive real quick how about easy start no buttons no display for now.

You will need Arduino nano + prototyping board.

This is only for reading the two drives switches and showing it on Serial Monitor set to 115200 baud.

Arduino code:

Maybe something like this:

It's not tested and it's SMT heavy. But it combines my drive ID switch and Igor's drive id display on a single board (50x30mm) with a cable running from the existing control board connector on the main board to this one. So far that's the smallest size board I've been able to cram the parts onto. Might be able to go a little smaller.

I could duplicate the circuit and put both on a single board of longer length. But each drive id switch and display is independent of the other.

Chri O. · June 11

I got a dump question if we change the drives ID while powered up will the drive actually accept the new settings or do we need reset (power cycle the drives) ?

I believe you'd have to power reset both the drive and computer in order for both to be in sync after changing the driveID. This board is a fancy way of not having to use the dip switch on the back of the drive and having an led display of the drive ID.

Chri O. · June 11

Well my plan:

Use one of 7407 IC Hex Buffers Drivers With Open-Collector. For the drives ID switches under software control.

We need four drivers for the switches and the two for CPU reset.

No buttons but joystick: ANALOG 2-AXIS THUMB JOYSTICK

Perhaps we can modify this for installation: StarTech.com 3.5" to 5.25"

I really like it. Looks like you have two ID displays and selectors on the single board. I'm happy to trial it if you are happy to send me the PCB files?

What is the width and length of the space available to install such a board?

Would you want to install the other items? Track Display, Reset and Bios Switches?

I actually have a heap of space in the case as there is a spacer between the two drives if you can see in the photos. However, for other future users I suspect they'd like a small board for potential installation. For me I'm not fussed size.

With respect to additional features, having access to track display would be great. I don't need reset to bios switch but it might be a good option for other future users.

What is key is that the displays need to be remote from the actual controller boards so the ability to connect via a ribbon cable so I can mount the LED displays on the case without the boards getting in the way.

Maybe as long as you can keep the board height below the hight of a standard 5.25" floppy drive mechanism then that would work great for me.

Thanks for assisting - you are awesome!

Okay so I am assuming we can shove a full drive 5 and 1/4 size device in the middle. Am I correct here ? 😃

Note: no picture or link in this thread.. I've been looking for it?

Sorry - previous thread. Photos at top of this link:

I know this is an odd question - but can the track number be taken from any of the primary IC's on the XF551 MB similar to this thread? for the 1050. I got the track display for a 1050 working via a Uno board and this code (slightly modified). Wondering if something similar could be done for the XF551?

The XF551 reimaged boards both have track display circuitry on them. You just need to fully populate the boards and then have the track display aux boards from my site made and populated. Add the FFC cables and connect.

In your case I think I can pull together both the drive ID display and control and the track displays for both drives on a single board. But you will have to fully populate the XF551 boards with the track display circuitry in order to use it. Cabling might be a problem, looks like four cables for the two drives.

Let me dive into Diptrace and see if I can come up with a design in the next day or so, that is as simplified as possible.

Okay:

I have a version 1 non-tested board that combines controls to switch OS and drive ID and reset the drive without power off. The untested part is primarily the Drive ID LED display, the other features have been tested in other forms. You will need to have a fully populated XF551_A v4 or XF551_B v7 pcb(That includes the aux circuitry). Remember to set your Drive ID on both boards to 4 and remove the OS jumper. This new board will now control those options. This new board is 40.5 x 147 mm, slightly less than the normal standard 5.25" drive bay opening. Take note of the FFC cable length as you might be able to shorten it depending on how you arraign the boards in the case. I gave the part # for the 200 mm as a guide on what type of cable is needed. They do come in various lengths.

I did not consider how to mount this board as it is still considered a prototype. You should still be able to carefully hot glue the board in place regardless.

The attached file contains the schematic, BOM and gerbers.

Here's a mockup of what the finished board should resemble.

Haven't got around to purchasing the boards yet. I was looking at the option to get the board pre-populated and save me a bit of work but the cost was staggering. I'm a bit distracted right now but plan to take a look at this in the next few weeks 🙂

Well, finally purchased the boards and arrived today. They look great. Will start populating over the weekend and will advise how it goes.
