Well, yesterday I picked up a new toy..
an A500 with a PSU and a external Floppy.
My friend Alex (Hes a mod here) had added an extra
Ram mod that also had the PROC and went over the orginal
PROC slot. This board never sat right... no matter how I tried
I could not get it to boot.
This is not the problem
FINALLY my dad got frustrated, removed the expansion board and took a flat blade screwdrive and removed the 68000 from the expansion board. And Put that back into the orginal slot.. booted right up! This is the problem.. when it wasent working correctly the HDD spun up and detected, but now that it works the HDD never spins up and I have no idea whats on it or how to access it.. never used an AMI with a HDD before, (ive used an AMI 1000 since 1990 I was 5 yrs old, which has no HDD) how can I do anything with it Help???
-
Do I need to press a certain key or keys to boot from HDD?
-
What kind of HDD contrller do you use?
An external one connected to the side expansion slot?
-
Umm.. its actually inside the AMI.. I can hear and see it spin up.. seriously. underneath the keyboard I see it saudered to the MOBO.
-
The device underneath this metal cover, that spins up and sounds like a Hard Drive. you can see how i lifted up the keyboard its on the right side underneath it.

I cant find any info on the Amiga 500, or 500+ having an internal HDD.. but this one does.. is this thing an A600? I have personally heard it spin up and make normal HDD sounds.
-
OK I see barely at the top written DISK DRIVE.. now how do I make this thing work?
-
Hi :)
what kickstart do you use?? Did that memory expansion (the one that didn't work - you wrote about it before) come with a kickstart switcher?? don't remember well, but I had a problem with a HDD in my A500 caused by the kickstart 1.3 ROM - when switched to 2.05 the HDD booted up, and worked (almost) perfectly.
BTW can you make a photo of it with the metal screen removed.. maybe some closeups of chips on it..
-
If I can figure out how to get it off...
-
ok.. first of all..
does the computer have a numeric keyboard???
If yes, it's an A500, if no, it's an A600..
try to find some pics of Amis on net and compare to what you have..
Unless ofcourse it's not a custom made A600 in an A500 case :))
-
well.. the metal cover is saudered together, the bottom plastic plate fell off.. gotta put that back on migh as well try the other board again
-
ok.. it goes on the expansion slot, right??
try to remove it from under the Ami..
gotta go now.. but'll be back..
-
Damn I almost broke the 68000 Chip getting it back off.. bad bad tool to use.. but got it back on the expansion board.. now I dont know if I can get it to sit right
-
OK.. board on and sitting i think right.. power light, hdd going but no video
-
OK 68000 PROC back in its slot on the MB screw the expansion and the HDD.. I just want it to work period.
-
Any chance of a few more photos of the hdd and the the other processor board.
Have you tried removing the hdd to boot up without it attached.
Also we need to know what you are trying to view it on and which video output you are using to connect to the display unit.
-
The metal thing you see on the picture is nothing more and nothing less then a 512K memory expansion from C= (the original A501). A hard drive can be fitted internally but you should find it somewhere else! There are at least 2 IDE controllers which fit on the 68K socket, one being the ICD Ad-IDE the other (though very rare) would be a viper 520 or 530.
A harddrive needs power, if you open it up the power to the floppy drive should be split in 2 and lead to both the floppy and the harddrive.
Or maybe the floppy drive was removed all together and replaced with a hardrive? We need more pictures to be certain.
-
Im trying to tell you I have heard it spin up and click like a hard drive.. its there I know it. and yes I have 3 floppy drives, one internal and 2 external
-
The bottome pops out, but the device thats underneath it (Which I know is a HDD, from what Ive heard atleast) will try to fall out but it soldered to the MOBO.
-
And like i said in very small letters are written DISK DRIVE
-
Here are two photos:
PHOTO 1: shows the expansion board and where it went
PHOTO 2: shows the connection (look to the right) that the HDD or whatever it is connects like

Yea thats the A500 I gave him.
Josh,
You need to make sure the RAM board is seated properly otherwise it will not boot. It has no HD..its a floppy drive. The silver triangle shape thing is a A501 ram expansion. So you have 512k there, 512k on the mobo + 1.5megs on that A500 insider. It worked fine here but like I said make sure its seated properly..thats why I gave it to you cause its a pain in the butt board. LOL

Ok.. I was confused badly.. now if I could figure out why some of my games dont work or crash then I would be happy with it. is there any way to clean the FDD drive, or run straight from the externals?
-
if you want to run it straight from a external you need a ...I dunno what to call it.. its a board that plugs into some chip that lets you use a external floppy to boot from (I forget which chip exactly). I have one but I'm using it. It was made by ICD, the people who made the AdIDE internal IDE kit for the Amiga 500.
EDIT: you need a Shuffleboard..
