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!
