Mainframe emulator cards for PCs are essentially no longer available or practical. It doesn't appear that any PCI or PCIe bus cards were ever produced, and the ISA cards don't show up on eBay.
This is presumably because the software emulators work well enough:
"Popular Software Emulators
- Hercules: A widely used emulator that can simulate IBM mainframe environments, allowing users to run various mainframe operating systems. https://en.wikipedia.org/wiki/Hercules_(emulator)
- QEMU: Another emulator that supports running mainframe hardware, particularly useful for Linux environments." https://en.wikipedia.org/wiki/QEMU

| "Hercules by itself only provides the implementation of the hardware instruction set of IBM mainframe architectures, S/370, ESA/390, and z/390. In order to utilize Hercules, it is necessary to acquire either an operating system or a stand-alone program that has been designed to run on IBM mainframe hardware. Like the hardware itself, the operating system software that runs mainframe computers is prohibitively expensive. However, there are older versions of several of IBM's popular operating systems that are now classified as Public Domain, meaning that they may be obtained and utilized freely. | |

| The Hercules community runs a variety of vintage IBM mainframe operating systems which have been determined to be in the public domain, including MVT release 21.8, MVS release 3.8, DOS/VS release 34, and VM370 R6 (all from the 1970's time period). Linux/390 by its very nature is publicly available. Under the disaster recovery provisions of their licenses, some have successfully run more recent operating systems on their Hercules enabled systems." |
