I started this some time ago, but never really got it finished.
It should be noted that I had it working "as is" previously, but all the file names were being truncated.
Now its just "broken" and doesn't find the drive at all...
But I still set about redoing all the wiring, so the lid would actually close!
Original plan was a slot load drive, with just a slot routered into the back of the case... but I stuffed that up.
So I changed to a tray load, but couldn't get workbench to recognise that drive at all, so changed back to slot load.
I believe this dvd drive is hardware set to master, as a result, the compact flash is set to slave, and it seems to boot from this just fine...
Onto some pics!
Mmmm... melted plastic....

Not a lot of clearance at all.. I originally had an adapter that converter it to a 40pin full size IDE, with a separate power connector.... fail!
(http://imageshack.com/a/img5/1686/ewqq.jpg)
(http://imageshack.com/a/img163/15/qcgh.jpg)
So today, I set about making a new cable, routing it as neatly as possible, and being a bit creative...
(http://imageshack.com/a/img850/2329/svya.jpg)
This meant removing the IDE connector, and power connector, and soldering the ribbon cable directly to the board...
(http://imageshack.com/a/img24/5598/g46o.jpg)
Basically how the drive and cables sit once the drive is in place.

Mmmm.. clearance...

Oh, and the work area! Amiga 500 to the left, been used for parts, 286 laptop motherboard sitting ontop of the soldering stations, has battery damage I'm working on.
(http://imageshack.com/a/img198/2681/qckn.jpg)
Flip top!

Which is handing for when you connect it all together, and realise it won't boot anymore... CF card master/slave jumper had gone dicky.

My $5, 19inch LCD monitor, complete with svideo input... lovely!
(http://imageshack.com/a/img546/8181/z9fw.jpg)
And this is how far the disc ejects from the drive...

Now.... the final step.... getting it to actually work... :laughing:

Very nice!
I've always fancied an A600 to mod and I've periodically placed bids on Ebay but never managed to clinch the deal.
That's a proper electronics tinkerer's workbench as well - nice one. Ahhhh the smell of leaded fluxy solder :)
PS: What's that bit of kit on the very far left edge of your work area pic?
-
Thanks!
I like the A600, because we had the A500 as kids..
But you can easily add a HDD, Svideo output, and cdrom drive all internally, for cheap!
I also plan to stack the extra 1mb of memory ontop of the memory on the motherboard, so I can put a DC-DC power supply in the trapdoor slot, and run this off a much smaller laptop power supply, as all my Amiga bricks are 2kg bricks!

Annoyingly, it worked, once...
The machine was being a total pain, refusing to boot at all, it seemed to be in a constant reset loop, occasionally bringing up the kickstart screen...
And then, it presented a software error, rebooted, loaded workbench, mounted the cd rom drive... and no file names were truncated... :furious:
Restarted it, and it refused to mount the drive again...
Magnific!
Thanks! I'd seen some pretty average looking cdrom drive installs in Amiga 600's, so thought I'd post my pics to help other out who might be considering doing the same ;)

If you don't mind I will use your 9th picture as wallpaper for my next AmiKit Real update :) . It looks marvellous with 256 colors and looks also nice with 16.

@AmmoJammo
I'm no expert but it could be confused by your IDE cable . . . :)

Nice work!
Here is my A1200 with internal CDROM mod done in 2009.
I used 4way buffered IDE splitter with IDEFix97 sw.

I came across that thread yesterday while looking for pics of something else Amiga related, looks good ;)
What I have succeeded in doing today, is I've managed to make it so that if the CF card is plugged in, the Amiga refuses to do anything... :hammer:
I also managed to break the compact flash adapter... I think I ended up with two pins shorted on the CF socket...
ended up completely removing the socket, and resoldering it from scratch...
doesn't work still..
compact flash card still works in a PC, in winuae, and I also tried setting up an old 40gig ide drive in the Amiga, which it found, partitioned into two 4gig pieces, then failed to format....
maybe I broke the ide controller? maybe the 40gig drive doesn't work so well...
Anyway! it works even less now than it did yesterday..
-
Sux, I hate when things break when you trying to make things better.
BTW, I'm using 4GB microdrive, a small HD inside CF card. Works very well.
I would try smaller HD, if you have one.
-
Tried a 4.3gig 3.5inch ide drive. partioned and formatted fine. Simply copied all the files from a workbench disc onto the drive, and it booted up quickly with no issues. So the ide controller is fine. I've ordered some new compact flash adapters.
-
You have it set like this.
CD drive-------MB-------CF
Might try this way.
MB------CF------CD drive
I know that back in the day connecting the Mb to the middle of the cable caused all kind of problems for PC clones
Just my opinion.
-
Its a definite possibility that the order matters... but I can't find any hard evidence to suggest that it actually does...
Right now, it won't even boot from the compact flash with no cd rom connected... :P
-
Great job. Back around '02 / '03 I put an A1200 in an A500 case and used the extra space to put in a slim DC drive in place of the floppy, Midi adapter, accelerator, scandoubler etc. Don't have it any more (sold it to someone in Australia in '04, postage was £80!) but must have photos on an old CDR somewhere.
-
The issue may be clarified with better ATAPI support using the ELBOX buffered interface and IDEFix97 software; these have made easy work for me accessing CD/DVD drives on a 1200.

Its all very... red! nice :p
I've currently got this dvd rom drive working...
However, I'm not using the CF card (really just a test)
40gig 2.5inch IDE drive, two 4gig partitions.
Drive formatted through Winuae, Classic Workbench copied through Winuae.
Hard drive set as slave, dvd drive set as master, using the same cable I was using on the CF card (yes, both drives are being powered by the ide header (http://www.amibay.com/images/smilies/shhh.gif))
Now, I've just installed IDEFix97, which at first wouldn't find the dvd drive, but did the second time I ran it..
CD rom drive worked...
However, IDEFix would never run with the CF card and adapter, it would crash before it installed the drive...
Copied some files from a cd to the HDD... seems very slow, but then, I am probably used to my Amiga 500 setup...
So, when the new CF adapter arrives, I might try copying the setup as is, from this ide drive, to the compact flash, and see what happens...

Had to laugh... as soon as I read this comment on his Workbench I immediately scrolled up and had another look at his Workbench screen and saw nothing special about it at all. Infact I thought "it's dull, boring and just plain wrong" (4 colour mode etc). Then the penny dropped. :rolleyes:

;)
What you can't see in the pics, is that the ceiling is only about 6 foot high, and there's two 36watt fluro tubes mounted less than 3 foot above the bench... its bright!
-
I ended up getting this working... although I don't recall the details..
However! the A600 is back/still on the bench!
The idea now, is to add a DC-DC power supply internally, to run the A600 off an external, 19volt, laptop power supply.
The only PSUs I have are the A500 bricks! Which kinds defeats the purpose of the compactness of the A600!

Oh, and I was repairing an amplifier, that had some warm resistors inside it... left it on while I went to get Hungry Jacks... so used it to keep my fries warm while eating my burger ^_^

Hopefully Hungry Jack's doesn't substitute Roo meat for beef (a perpetual rumor about the chain's licensee Burger King).

Where can i purchase one of this dvd portable conector to IDE adapters?
-
@kickstart
This is the one I used... with audio connector too...
(http://www.ebay.com/itm/Slim-Optical-Disk-Drive-CD-DVD-IDE-to-Desktop-IDE-PATA-Interposer-Board-Adapter-/29097765727)http://www.ebay.com/itm/Slimline-CD-DVD-ROM-to-40-Pin-IDE-Adapter-/170950610516?pt=LH_DefaultDomain_0&hash=item27cd734e54
This is a real easy solution when using a Fast ATA MKIV from AmigaKit... but will work with a four way IDE interface too... just tricky with master/slave and connecting the ribbon cable correctly to the MB IDE connector.
Connecting audio out to A1200 MB...

Big X-Files fan, are we?
Same house I've lived in for my entire life (minus about 2 years a while back when I moved out)
The X-Files stuff was all from my older brother, 15+ years ago. There is also a large "X-Files" logo on the wall behind the 286 motherboard in the top left, and a few other bits and pieces around, such as "trust no one" :lol:
-
So you inherited this neat little work area.
I like your toys.
Is that a hot air rework station I see in the pictures?
-
Nope, living with my parents while I save a house deposit ;)
Pace desoldering station, cheapo hot air rework/soldering station, and a Quick (brand) soldering station.
The hot air mainly just gets used for heatshrink ;) its cheap and nasty, but it gets the job done.
-
Yeah, about the only use I've put hot air to is repairing smt capacitors that come off boards.
-
I may have ordered an aca620 for this... wish me luck making it fit! I'm also revisiting the idea of fitting an internal dc-dc supply, with a few bits and pieces on their way from eBay.
I'm aiming for a power supply that's good for 5volts at about 5amps, and 12volts at 5amps, not because the a600 needs 12v at 5amps, but rather because I can steal 12volts out of the original power input jack to run an lcd screen ;)
-
The ACA620 is a cracking little card. It'll make your A600 fly comparatively :)

Nice clean mod, thanks for sharing! Looks sharp!
-
Will be nice to see you fit the ACA620 in that one ;) The ACA600 looks smaller then my Vampire 600 board at least so "should" fit under the optical drive ^^
Good luck, waiting for pics :)
-
I doubt an accelerator will fit in there but for your sake I hope I'm wrong. Why not use the underside of the drive to mount the CF?
If it was up to me I'd probably skip the internal ODD for other internal components but if I had to, I'd mount a slotin drive to the side instead... would give more room for the accelerator and a more "natural way" of inserting media into the machine.
-
It'll fit... I'll make it fit ;)
-
It'll fit... I'll make it fit ;)
Remove the ROM socket and mount it directly to the board? Might give you an extra mm or two in that area. ;)
-
Its the clearance between the accelerator and cd drive that may be an issue, namely above the 68000 cpu.
The plcc sockets appear to measure 8.1mm, plus a 1.6mm pcb. I can always trim the pins flat to the board ;)
So, do I have 10mm of clearance between the motherboard and cd drive... I dunno, I'll worry about that when it doesn't fit! I have a file and I'm not afraid to make the cd drive housing smaller! xD
-
Heaps of room in there!
(http://oi58.tinypic.com/xe4i9s.jpg)
I mean, you can make the lid fit ok.... xD

Are you absolutely sure that your dvd drive isn't shorting on your 68000 adapter pins? Looks like it is to me...DON'T POWER IT ON UNTIL YOU'RE SURE! :(
Better to insulate and play it safe (if not already done so).
-
I know its not shorting, because I cut the pins off, and there's two layers of kapton tape over the board ;)
I need to modify the ide cable now, as obviously it won't fit where it used to run...
-
That is dang impressive! Almost makes me want to do something crazy like fit an optical drive inside my cell phone or something, just to one-up you, haha. :lol: No, seriously, great work! :banana:

I'd like to see the keyboard in place now. Looks pretty tight to me, but it looks as though you're well on the way. ;)

Keyboard has already been fitted with the optical drive in place, and the optical drive hasn't moved.
(http://imageshack.com/a/img32/9032/eqqe.jpg)
I'm going to try and get another half a mm or so of clearance between the accelerator and the optical drive, as I think its a bit too close :hammer:
-
haha great work, knew it would fit ;)
-
its all together, for now, and it works.
However, while I had it apart, I changed the ide wiring, and now the cd drive refuses to auto mount...
Previously, it would only mount if there was a cd in the drive, now it will never mount, even putting it at the very end of the startup sequence, after workbench has loaded!
However, type "mount CD0:" in the shell, and it mounts every time, even without the cd in the drive, so maybe I'll just mount it with a shortcut from now on ;)
(http://oi57.tinypic.com/2d26at1.jpg)
I'm also planning to add an internal DC-DC power supply, so I can run the Amiga off a small laptop power supply, and may in the future add an A604n, and an Indivision scan doubler ;)
I also believe that the CPU needs a heatsink... it got to about 70 degrees doing basically nothing.... I'm also considering adding a fan to the top of the case so there's some active cooling.
-

Needed a heatsink ;)
(http://oi58.tinypic.com/28stx00.jpg)
I do however now suspect that the ide cable is putting pressure on the bottom of the drive, and putting a load on the eject mechanism when trying to eject a CD...
-
I ended up building a messy DC-DC converter, just to get it running, so I didn't have to carry the 1.8kg original power supply around.
(http://oi58.tinypic.com/jsee85.jpg)
Its not the final version, as the parts I'm waiting on haven't arrived yet, so it was just made using what I already have.
The -12v rail is coming from a dc-dc module that does +-12v, but if you unevenly load the rails, they go fairly out of spec, so I'm only using the -12v, with a small load applied to the +12v side to keep it balanced.
Meanwhile, I'm using a 93 cent dual output dc-dc module off ebay, modified to give the +5 and +12volt rails.... what can possibly go wrong!
-
Are there any 3.5 inch DVD drives that cold go where the FDD goes?
-
When I press the right shift key, I get about 8 keystrokes across the keyboard, including caps lock being turned on xD
Oh dear....

Work in progress on the new internal DC-DC power supply... xD

I actually ran it off the bodged together power supply at the bottom of the pic for a few hours, the regulators and/or inductors got hot enough that you could smell them from outside the case, and there's a module that does +-12volts, with a resistor on the positive rail, as I was only using the negative rail... There's capacitors on the bottom, fake Rubycon most likely (http://www.eevblog.com/forum/Smileys/default/tongue.gif)
The final design above still isn't the final, one regulator isn't soldered on, as its the wrong part, and I plan to run bigger inductors all round, so I'll finish this board, make sure it works, then build another (I etched two already)
-
Looking might fine there :D Will be nice to see the final one installed in the case! Are you or have you planned on removing the Amiga square power connector? Keep up the good work :)
-

I'm going to leave the original power connector in place.
It makes it very easy to measure the internal power supply rails if needed, or run external devices off the internal power supply (the 12volt section is designed to be able to give 5amps, while the A600 needs less than 1amp on this rail, from memory)
I still need to put the VGA connector in place of the RF output, and relocate my SVideo connector to the composite output location :hammer:

ACA620, with heatsink, overclocked to 25Mhz.
Internal slot load CD Rom drive.
A604 and Indivision ECS.
Internal DC-DC PSU (will happily do 5volts at 5amps, 12volts at 2amps)
4gb compact flash card.
Still has the original floppy drive too!

Looking good mate! :)
Is the ACA running stable at 25MHz with the heatsink?
-
As yet, I haven't run it for an extended period.
With the power connector were I've put it, the lid won't fit on :P
I've got some cheapo thermometers on their way, as I want to keep an eye on the PSU, and CPU temperatures the first few times I run it, with the lid closed.
I was also considering adding a fan into the top of the case, but I'm not sure how much this will help...

Personally I'd use a fan if that was my rig. Even a slow fan will do as it will move at least some air about. There's a small space to the left of the floppy where some heat vents remain. I'd probably rest it in the case at 45 degrees, drawing air from the vent blowing it towards the front. If the cpu does get hot, then just put the fan anywhere... As long as the air flows towards the heat sink.
I have a fan in my A600, as mine has a ACA630 which in my mind is too warm for comfort without the fan.
