Amiga 1000 Not Booting to Workbench

[mindprober]

Alright guys, I've got some horrifying pictures for you.



Amiga 1000 as found, not cleaned yet.

Yeah, ya think? Man, that is the filthiest computer of any kind I have ever seen! Jeeze, it looked like someone used the keyboard as a toilet for cryin' out loud!!

All that aside, I still think it is a great find! As Acill pointed out, that Amiga ball logo is not seen very often.

[Steady]

Wow, that is the dirtiest I have seen. I can't believe it even works ... but it does.

The 2 second pause will be the loading of the Comm app and it is that which is looking for Comm.keys. It is designed to boot straight into that. If you ever get that keyboard working then making changes to your startup-sequence can sort out your issues. It seems you have slightly more pressing matters though :-/

[Alley_Cat_Jack]

Yes, I did in fact find it inside an old barn. The system and the keyboard were on the side of the barn that had a leaky roof, however it was on a shelf and under stuff, so how much rain water got in her over the years is questionable.

I went through the hundreds of disks on the other side of the barn that didn't have a leaky roof, and among them, I found these!



There were other Amiga software disks as well, but I just grabbed up the ones for booting and the Supradrive for now. Some of these disks are pretty dusty on the outside though so I have not put any of them in the system yet. Does anyone have any recommendations for dusting them off to minimize the amount of dust and dirt that gets into the drive? I have not pulled back the dust cover or anything on these so I don't damage them.

So far I have still not been able to locate the second half of the Supradrive, the mouse, or the keyboard cable. Will a standard RJ10 cable that goes from a phone receiver to the base work as the cable, or do they have a different wiring pattern that I will have to change? If that will work, and I can boot, I can at least test to see if the electronics are working on the keyboard just by jumpering keys on the PCB. I will then at least know if doing work on the keyboard is even worth my time at the moment, or if I should set it aside for now if the electronics are dead.

Ha! Those disk labels are hilarious.

Any idea the history of this system? How'd it wind up in a barn?

[Alley_Cat_Jack]

I don't know much about how it ended up there. What I do know, is that the person who used to own all of this computer equipment I found, used to run a networking business of sorts out of his house. The barn is full of old dial-up modems and such as well as computer parts and expansions cards of all ages. He seems to have had some money as there is a lot of stuff I have found that were particularly expensive and not an every day user kind of stuff, such as the server I found. It would seem that the barn was used as storage over time. The stuff inside the house was more recent, and older stuff got moved into the barn for storage.

Here is a picture of the bottom of the system to show the serial number. I haven't found a source online to determine if this was first run or not. Does anyone have a link to a list for the serial numbers?

an amazing find!  around here we usually hope to find old dodge charger daytonas or superbirds in old barns, but what you found is what i would wanna find, other than a '69 charger.

not sure i would even bother with that keyboard, i would be afraid of it causing issues with the main unit.  but i would definitely remove the case and start cleaning out the system.

i think alot of us wanna see whats inside also

but otherwise, a great find!  she will clean up pretty good!  i would proudly put that old war horse on display!

i just repaired another A1000 to add to my collection and I have another one in line for repair, I love the A1000, was my first Amiga back in 1987.  you can never have too many A1000s!

good luck!

Alright, so tonight is the night to open up the Amiga. First I wanted to try out some of those disks. It looks like half of the Kickstart disks work, the others don't. The issue I am faced with now is that the disk auto detection doesn't seem to be working. I managed to get it to work a single time by fluke, but it happened to be a non functioning disk that it happened with, so I didn't get any further. I can now get to the insert Workbench disk, but unable to get passed that point. After opening the system and removing the disk drive, I figured the little switch on the right was the disk detection switch, however, it seems to check out fine with the multi-meter. Does anyone know where the disk detection switch is? I figure this is why there was a Kickstart + Workbench disk in the drive when found.

On to the tear down! Or at least as far as I have dissembled so far.




The shield here is looking pretty rusty, but, but not as bad as the RAM or the keyboard.




Power supply seems to be from Oct of 85.




The inside is reassuringly clean!




The three girls. Denis is R5 rather than R6. From my understanding, this indicates an early American model that does not support EHB.




Not sure if any of these had a variation from early to older models, but here is a close up anyway.


Is there anything else you guys would like to see, or further tear down. I still have it opened right now as I am trying to figure out the disk drive's auto detect. Any help or suggestions on that would be great.

[Alley_Cat_Jack]

Wow, some days some of us are just oblivious to things. Usually Me.




Huh..... Well that's odd placement for a button...




Opps, looks like they missed the mark with the screw holes. Well it WAS the first model, sometimes these things happen and quick fixes are needed.




Wait a minute... Mitsubishi? What are you doing here? From the future you say?


It would seem that this drive has been replaced before and I feel quite silly that it took me that long to realize it. I'm wondering if this is the cause of my auto disk detect problem. I was looking at the wrong switch earlier for disk detection, but soon found the correct one with the help of a YouTube video. All switches are working fine it seems. The fact that this is a drive that was swapped into it later, and that the auto disk detect isn't working is likely why I found a disk with Kickstart + Workbench 1.2 in the drive.

Is there a key that can be used on the keyboard to initiate the reading of the desk at the insert workbench disk screen?

[kneehighspy]

wow! looks much better inside than I thought it would.  looks like someone replaced the original full height floppy drive with a half height drive sometime in the past.

i would try cleaning the drive head to see if that helps, but i think you mainly have a bad disk problem, the drive is probably ok.

thanks for the posts!

[Alley_Cat_Jack]

No, I don't think not is a drive read head problem, because when it is trying to read something, it reads just fine, no struggling at all. The problem is that it doesn't detect that insert the disk. I was thinking though, and since the drive will read a disk just fine if the disk is in the drive while you boot, it clearly must since that there is a disk in the drive. The problem might in fact be that it doesn't detect that the previous disk was removed. This is of course speculation as I do not know exactly how the drive's disk detection works, other than the physical switch.

There are some guides out there to modify other disks drives to be comparable with an Amiga. I haven't found one for this particular drive yet though. I'll be returning to the barn tomorrow. There were a few drives in there that I might check model numbers to see if any of them are able to be modded to work with an Amiga since it looks like an official drive would be quite costly.

For heavily dusted disks, I'd use a vacuum with a really soft brush attachment.

Yes you can have to many A1000's because I have been trying to find a working clean one for years and everyone sucks em up to put on a shelf or store in a garage out of greedy hording issues!

[Alley_Cat_Jack]

Today I found a drive laying around that happened to be compatible with Amiga computers with very little modification. I used the information here https://www.youtube.com/watch?v=QtMvoql0W8Y and here https://translate.googleusercontent.com/translate_c?depth=1&hl=en&prev=search&rurl=translate.google.ca&sl=de&u=http://honi.hucki.net/samsung.html&usg=ALkJrhiCrCz6osuQrYinWhZXzN6SttrZfQ



Here we have a nice clean and functioning Samsung SFD-321D modded and ready to go with an Amiga computer.




I once again tried to boot with the kickstart and workbench disks and tada! It works! The system now boots up into it's OS.


Now I still need to see about getting the keyboard to work, and finding a mouse that is compatible.

hang in there bud, you will find one.  I got lucky on my last one that came with the spare motherboard, they were both listed as doa.  i bid $31 on it on ebay and won, shipping was like $14, so $45 wasnt bad.

replaced the main 256k ram in the unit, was showing main ram error, and it works fine now.  the motherboard is showing the same error, so hopefully thats all it is, but i can only start there first

you will find one tho!

//kneehighspy

[Alley_Cat_Jack]

Yeah, this is my first Amiga, and I have been after one for years myself. I'm so happy I found it and that its is turning out to be in a lot better working condition than I initially thought. Much better than that NES I caught while fishing last year....

[Oldsmobile_Mike]

954,376 free ram? That's not a standard ram expansion ya got on there.  Normal would be 256k on the motherboard + 256k in the front...
