Is this possible?

i don't see why not. you may have to run some extra lines from the expansion slot that are missing from the CPU socket...

cpu socket 64 pins
side port 86 pins

other thing you can do is make a port doubler for the side slot of the A500, then you'd have all the lines you need. i imagine you are going to have the GVP sat on top of the A570...

another thing you can do is get a CPU accelerator that goes in the CPU socket. these are often faster, and carry more ram than an A530, (32-128Mb as opposed to 8Mb).
but you don't get scsi.

or just get an A530 and an external scsi cd drive. the only thing you don't get then is booting off of CD-rom, but the advantage that you arn't limited to the single speed, caddy loading mechanism the A570 has....

yeah i think as far as i know, the viper was the only internal A500 accelerator with an onboard hard disk controller. i think there was an option for scsi on the viper aswell, plus more than 32Mb ram....
you may be able to get a supraturbo28, an external 8Mb ram box, (i don't think i've ever seem the 2Mb ram expansion for the A570) and a 68kIDE board that plugs into the internal 68k socket and allows you to have an IDE hard disk inside the A500. that would still leave you a side port slot to bolt the A570 into... not to mention an increasingly long A500 :-D

otherwise you're stuck looking for the scsi expansion for the A570 and some form of scsi drive to plug into it.

i belive there are hard disk controllers that plugged into the side port that had a pass through, but i think the last time i same one of those was pre 90's

i'd go with the external CDrom idea. however an A570 was the easist way i've ever bolted a CD drive to a machine...

heh, that brings back memories. my first A500, i had an ICD ad-ide under an Mtec020 board to lift it over a 2meg minimegachip agnus upgrade. i didn't care about the keyboard as the lid was never on my machine :lol: but it did work with an A570... even with the 3.1 upgrade... good times...

ok, so as you want to keep your amiga with its lid on, :-D your options are pretty much as follows:-

A570,supraturbo28,external rambox,68kIDE hard disk board..

A570,internal accelerator, no hard disk.

A570, rambox with pass-through, 68kIDE controller, no accelerator.

A570,find a hard disk with a pass-through,internal accelerator.

external scsi DVD/CD, scsi hard disk contoller+ram, internal accelerator or supraturbo28.

extrenal scsi DVD/CD, A530.

really you gotta ask, what are you going to use it for? if it is primerily playing CDTV titles then get the A570.
if it is just accessing CD stuff, then go for the external CD drive. you can kinda play most CDTV stuff on a CD drive anyway. iirc the IDEfix97 CDrom driver software off aminet comes with a CDTV/CD32 emulator for stuff thats hard coded to look for cd.device

i hope this is of some help in getting you to where you want to be :-)
