is there a connector for ide to serial ata hdd what does it looks like and where is it available from cause have a machine with pre historic mb
Short answer: No, mostly because IDE/PATA is not in use anymore.
Back in time, some MB have had both connectors, IDE and SATA, but now they are old.
There was also some controller PCI cards for IDE/PATA and for SATA, depending on needs.
Some USB devices are also able to connect to IDE HDD.

If you have an IDE HDD, the large connector is the IDE plug.
