Sounds great. Let me know when you're ready and I can message you my address. Thanks again!

If you don't hear back from me in a couple of days, please remind me!  My short term task memory is basically nonfunctional at the moment, so it may get lost...

WIll do. 

 

I actually had some luck with the SCSI hard drive this evening - after taking off the enclosure, it magically started spinning. 

 

Starting up the HD followed by the Plus lead to a Happy Mac... wonderful!

 

Of course - the story isn't over yet. The Plus starts to boot, I hear plenty of action during the boot, but it stops after around 30 seconds. The boot unfortunately gets stuck on the Happy Mac, and does not complete...... any ideas?

Many SCSI drives have rubber bumpers inside of them that turn into a sort of goo over time. When the drive head hits the bumpers, it gets stuck and prevents any additional data from being read. This is a common point of failure for many hard disks. It is possible that this has happened inside of your drive, however, the issue may also lie with corrupted software.

 

If you don't care about the data on the drive, I would first try reformating it with something like the LIDO program to rule out a corrupted filesystem. Maybe @cheesestraws can include some sort of disk formatting program on the disk they are sending you?

It lives!.... I finally got the damn thing to boot. 

 

Switching around and/or cleaning the RAM chips seemed to do the trick in the end. The hard drive seems to function well.

 

Now all I need to do is find a mouse - I'm thinking I might DIY something like this: https://hackaday.com/2017/01/23/bring-a-modern-mouse-to-an-atari-st/

As far as I can read, the Atari ST mouse output similar signals to the Mac Plus mouse (just a different pin-out), so a RPi + some code to emulate the old mouse might do the trick.

 

In the meantime, does any know if I can control the plus sufficiently only using a keyboard?

Does it have an OS on it or would you still like me to make a boot disc for you?

I built something to do this recently using an Arduino, see this thread which includes a link to source code.

It did indeed have an operating system on it, so I should be good to go without a boot floppy.  Thanks again for the offer. If the hard drive gives up the ghost, I may come running.

 

That device looks perfect - great build. I'll have a rummage around to see if I have one of those joysticks.

You are very welcome.  Just let me know if you do and I'll drop one in the post :-)

I'm not sure where mine came from honestly, but they seem to be very cheap on eBay :-).  If you need any more info on how to wire it up, let me know and I'll try to provide clarity...

So the machine is up and running nicely. Managed to build a mouse using the Raspberry Pi and the code here (https://hackaday.com/2017/01/23/bring-a-modern-mouse-to-an-atari-st/).

 

I'd quite like to upgrade to System 7 on the SCSI. What's the best way of going about getting System 7 installed on the SCSI without floppies?

 

I have a PowerMac G4 running OS9.2 with a SCSI PCI card that recognizes the hard drive - can I use this to install the new OS?

In an effort to archive the files of the SCSI drive, I connected it up to my G4. This worked well and I was able to copy over all the files.

 

However, connecting it back to Mac Plus resulted in a boot failure - I just get a solid floppy. 

 

It seems like connecting it up to the G4 running OS9 has messed around with the apple_driver partition or the boot blocks, so now I am without a working boot, unfortunately - Sorry to say that I may just need that boot floppy after all.

If you need it, then I can sort one :-).  I actually just got some "new" (second-hand) floppy drives in the post, so it will be a good exercise for one of those :-).

 

Does it have System 7 on it or 6?

That would be wonderful - Thanks again! It was running system 6.0.8, and seeing as the machine only has 2.5 MB of RAM, System 7 would probably be a stretch anyway.

 

My hope is that having the boot disk will allow me to see if the SCSI drive is mountable - then I can go from there.

Weirdly, I can't quote your last post.  Webapps are strange.

 

Drop me a DM with your address?  I'll try to get something sorted early in the week.
