I just borrowed an A570 and connected it to my A500. I use and RF-Mod. to get the picture and sound on my PC's TV card.
The quesition is; When playing a music CD i have to disconnect the audio cables (going into the RF) from the Amiga and plug them into the A570. When I want to hear any other sounds I must disconnect them from the A570 and plug them into the Amiga. Is this really the only way to get both CD- and normal audio???
Another question; Is there any way to use; both the A570 and an external A500 HD simultaneously?

you are using the RF to get the sound into your pc???
The A570 have amigasound in connectors according to this mag i have here so connect like this.
A500RCAout==to==A570RCAin and then from A570RCAout==to==RFmodulatorRCAin

No not an external A500HD but there was a SCSI-card for the CDTV which fits the A570. I think I also have seen an A500-expansionbus splitter in an old amigamag but to find such a rare beast...
-
Ok, I think you just solved the problem. Have'nt tried it yet but still, I think you're right;) I was wondering what those RC-in connectors on the 570 were useful for, now it seems pretty obvious.. Sorry for beein stupid...
About the HD thing.. That's too bad, really. Would have been actually quite USEFUL to have both the 570 and the HD together. But.. then again,... we have to remember it's OLD stuff we're talking about.. You just cant get everything..
-
By the way, why could'nt they just make a "pass through" connection on the 570 or on the HD? ´Like on the external floppy drives.. Or thats just not the way it works perhaps?

Only some newer hard drives had a pass through connector. But really, an Amiga with a cdrom but without hd drive isn't very useful...

But still. you mean to say that there ARE, some HD's for the A500 that sports a pass-through connection.. That would, for example, let you connect the A570??
The HD I'm talking about I's a DATIC 40MB disk.. Has no pass-through.. but a strange hole on the rear (who has'nt;)). Which made me think that maybe some kinda SCSI cable could be connected inside and be popped outa that hole and then connected to the 570?? Just speculations, of course.. !?
-
What I used to do was use this little card that gives me a zorro slot (at least I think it was a zorro slot) from the 500 slot (plus a passthrough). I would hook the card to the 500, the 570 to the card, and then plug my dataflyer 500 (scsi and ram) to the extra slot the card gave me. The only problem was that I ended up with the dataflyer card sticking straight up in the middle of things.
It did work really well though!

It's easy to get CD and a hard drive on a 500, you just can't have them both directly connected to the side expansion port. Well, not without some rare, barely usable hardware. Someone used to produce cards that gave an extra side expansion slot, but the card was completely exposed, and your extra device somehow had to support its weight vertically.
Here's an easier solution:
Option 1 is to get the SCSI adaptor for the 570 and connect an external HD.
Option 2 is to get say, a GVP530 or A590 w/ SCSI and connect an external CD.
Bear in mind that most high-end A500 hardware is very hard to find now.

What kind of connector?Is it a DSUB(looks like serial and amigaRGB)?
An maxed A500HD had passthru, memory and SCSI, one model had both SCSI and IDE and another one had a 286-pc card.
I have found the expansion connetor splitter by the way

In the U.S. of A. there was the SlingshotPro which was a Zorro slot with a pass-thru. The plain Slingshot had no pass-thru. The Pro version would get along with most Zorro cards & could be modified to handle some 24Bit graphics cards. I have one somewhere, but do not know if it will play nice with an A570.
SCSI-TV (IIRC) was made in Canada and completed whatever was missing thanks to the C= beancounters to use SCSI hard drives. There was one model for the CDTV & onefor the A570. I believe a similar gadget got produced somewhere in Europe.
The SlingshotPro shows up now & then on eBay.
One of the pictures from Ami-West appears to show an A570 with another device between it and the A500.
Happy Hacking!

Does anyone know what interface the CD-ROM in the A570 has? Probably it´s commodores own construction.
Anyway what computer do you have and what specs are they, advice would be a little simpler if we known.
If you have a cd-rom in your pc(which i assume) play the musiccds in that because you don´t want to wear out your A570 unneccesarly.
There really is no point in expanding an A500 except for the fun of it.

I notice my A570 puts out some really low level audio output. I have to jack my volume way up on my stereo system to hear the music. Also the built in headphone jack if you're going to use it plan on buying some good amplified headphones. Other than that A570 is a must have for any Amiga collector as far as I can see. Wasn't this the first CD-ROM made for a computer period!? I think that's a different post someone asking if they should get one. Well it's not like it's state of the art but it is very cool and old and it works and you can download games whether you are a bad pirate or just looking for some public domain stuffs!
:roflmao:
website you should check out to see which games will work for A570: http://www.cdtv.org.uk lots of CDTV titles aren't compatible with it. not sure why. CD32 & CDTV titles do work with A1200's that have CD drives and a lot of 4000's too. At least this is what I've heard. Main point just watch out for the not compatible with A570 so you don't burn yourself a bunch of coasters.
-
@ceaser, there's something wrong - either with your A570 or your amplifier - the A570 should give a perfectly good and strong CD audio line output. The A500/500+ on the other hand, throws several volts out so in comparison the CD level is low in the mix, but you aren't really meant to feed those sort of levels into audio amplifiers.
Also, have you got the volume control turned up for the headphone jack? (it isn't just an on/off disable switch).
-
Don't forget you can crank up the volume with the front knob!
Using various expansions with pass-through connectors on the 500 can be a major pain - around 50% of the possible combinations simple won't work (reliably). Combining the A570 with a DMA SCSI controller is almost certain to fail. The 500 is simply missing a bus controller which the 2000 does have.
As posted your only options are
- expanding the 570 with SCSI for HDD
- replacing it with SCSI controller + CDROM alltogether (much faster)
- adding an internal IDE controller (slow)
-
Is there any way to use; both the A570 and an external A500 HD simultaneously?
1) Amitrix SCSI-TV 570 (http://amiga.resource.cx/exp/scsitv)
2) HK-Computer Vector Falcon 570 (http://amiga.resource.cx/exp/falcon570)
3) Possibly IDE68k (but that is internal).
Does anyone know what interface the CD-ROM in the A570 has?
Matsushita MKE (http://www.chiark.greenend.org.uk/~theom/electronics/panasoniccd.html)
The best purchase for your A570 is a 2MByte FastRAM card (http://freenet-homepage.de/x1541/hardware/a570ram.html). With one of these in your A570 you can play almost any WHDload game from CD.
-
I use an A570 with SCSI-TV and HD, Supra 500RX with 4 Megs of fast ram. It works with 1 or 2 Megs of chip ram. The A570's internal CD drive is not in the SCSI chain.
A570 doesn't like acceleration other than 7 Mhz 68010 (hard to measure benefit).
A570 will boot from a CD with the OS on it, if you can write your own (less need for a HD).
-
I use to use an AdIDE 44 in my CDTV so I'd imagine it would work with an A500 and A570 with no problems. Simple install, it just goes between the 68000 socket and CPU plugs back in top of it. Then you can hook up a 2.5" laptop HD inside.
Then maybe you could through a Supra Turbo 28 on the side (it has a pass through), I use to have the A2000 version and that thing was awsome. It speed everything up when you flipped the switch to 28mhz mode. It was basically just a 28MHZ 68000 and it would speed lots of things up even games that you didn't want speed up. (there was a switch to through you back to 7mhz mode) Yeah that might have been my favorite accelerator ever. Then plug in to that a AlfaRam RA5-8M which also has a pass through, and then plug the A570 into that. Should be rock solid! ;-)

Hi
This is a sexy little addition for any A500. A Viper 520 CD.

PPS Sorry
If you put your A500 in a case like the 'Checkmate' you can have say 2 external hardrives, and say two external floppy drives... And more.

The A500 was a magical computer when you think about it.

They are not rare, lots were released. No practical difference to A570 and just like A570 it is practically worthless.

Not as sexy as Viper A530! Neither of these cards were made in volume, both are like rocking horse poo and demand overly large prices for what they are.
I've said it 100's of times, the best upgrade for A500 is A1200.
-

Way back when - I had an A500 with a Supra hard drive/RAM expansion on it (with a pass thru) with the A570 plugged into it. It was the widest A500 in history (maybe) but it worked.

Not sure thats correct. These were the prototype that was given out only at shows and the like. When officially released it was rebadged. There is an interesting article on one of the CDTV fan sites about the rarity of the unit, and from the mail I get I would suggest few are in existence. Happy to be proven wrong. Always pleased when there are more Amigas around than you think.

Well, I had A500+SupraTurbo+ActionReplay/Datel bus divider/RocHard800 speaking of wide A500s...

Always liked the idea of a souped up A500 with an A570 and a Viper 530, would have been cool :-)
If anyone is interested I have my A570 up for sale over on amibay.

That's for sure, but nowadays many amigans have many Amiga to play with, and they have the insane idea to expand them with "uselss" hardware (me too). :)
The fact is that is pretty much like with old historical cars: it's nice to improve a "limited resourced" thing to make it work better, even if not near to today standards (of course you don't have to go deep to keep mental sanity ;) ).
Regarding the A570 and CDTV and the way to provide them a SCSI interface you can check this, by a clever italian guy:
