Title: Amiga 1000
Post by: trekiej on January 27, 2015, 07:00:13 PM
Hello.
I got an Amiga 1000 from a friend and it is real nasty.
I took it apart and want to check the power supply.
Do I need to put the power supply under load to check it?
Or do I jut plug it in and put a multi-meter on the leads?
Since it has been wet, I hope it does not pop on me.
Thanks.

If its been wet I would remove the PS completely, open it up and first see if there is alot of corrosion inside. If not then I would power it up without anything connected first.

Thanks, I already opened it and it looks good.
I will give it a try now.
edit:
Fan runs no exploding caps, so far so good.

I hooked up the power supply and fdd. I get the 4 led flashes and can hear the fdd look for a disk.

Well, it sounds like the damage might be minimal. Have you tried to hook up a monitor, do you see anything on the screen?

I am glad you asked, I got a Kick Start screen this morning on my Vizio 19" Lcd.
I thought something went bad over night. I reset the cpu and some of the chips around it.
I used the composite input on the tv.
edit:
wishlist:
Amiga 1000 rom adapter; needed
Amiga 1.3 rom from Amiga 500; have
Memory upgrade, I have not checked the memory module that was included.
A way to hook it to a monitor or my Visio.
I need a keyboard and mouse.

Dear god don't put any hack in there for a 1.3 ROM. All you need to do is get a 1.3 Kickstart Disk, and the 1.3 Workbench disk and you're in business. I really hate to these nice old cold computers butchered.
You would be amazed how many great games there are that need 1.2 and 1.3 OS. With a disk based A1000 all you need are the disks.
Add some extra memory, but leave it at that.

Hey @motrucker -

You seen this one?

http://frederick.craigslist.org/sys/4801333959.html

It's fairly local to us. $75 bucks. I've thought about it, but really I'd just pick through the software and throw the rest up on ebay. Have no time or room for another computer right now. But if you like these old ones, might be worth a drive down for you?

I wish I could make a replacement face plate and put in a new FDD.
A FDD emu would be good too, would it pick up the ks first?

How is the adapter by DJ Base?  Are the Roms at max size?

Does anyone know how to clean up a composite signal?
This could create a few chuckles. :D

Put it on ebay.  It's worth whatever someone's willing to pay for it.

25) The composite video of the Amiga A1000 needs color correction. Your
red, greens, and blues may not look correct.  The modification is simple;
just remove resistor R140; located on the rear-left of the motherboard. On
some A1000's, R140 will have to be replaced with a 470K ohm resistor
instead.



but, if you absolutely can't use RGB, better try making RGB->S-Video adapter.

@Olds_Mike: I thought about buying one. Maybe an external one is better.

@Orange: Thanks, I would like to buy one of those boxes that goes between a NTSC camcorder and a VCR and can correct color, brightness, etc. I will have to wait till I get the A1000 completed.

I did, but I am still not able to drive - so I can't do anything about it. I would have jumped on it. You're right it isn't far at all (I'm a little closer the you are) My A1000 is still working 100%, in totally stock form. I just need to un-yellow it a bit. Time for a can of Fusion.....

Has anyone had any success with a fdd emulator and an A1000?
Thanks.

I want to paint the A1000. What brand of paint would you recommend?
Title: Re: Amiga 1000
Post by: trekiej on February 15, 2015, 07:28:24 PM
I have started my painting. I need to complete the bottom and the front bezel. I wish I cold make a new bezel for standard fdd or for A1200 fdd.
Next is the metal pieces. The power supply and the Motherboard cage or cover.
I hope paint does not flake off the metal and get onto the board.

Does anyone here think it is a good idea for an Amiga 500/600 to boot from a Kick Start disk like an A1000?
Title: Re: Amiga 1000
Post by: motrucker on March 13, 2015, 04:02:46 PM
Why?  The 600 came with 2.05 IIRC, and that's a bit large to try to do by disks. With the 500, you could just use a workbench 1.2 disk (if it's a 1.3 ROM) and get away with that. There might be a few small compatibility issues, but for the most part, it would work. But again, why? There would be very few if any advantages.

Maybe it could be good for developers.
Also, I wonder if it is good for FDD emulators.
Being able to swap out Kick Starts when needed.
Me, I rather have a 3.1 Kick Start and an accelerator.
