The 7i90 in SPI mode works well with the Raspberry Pi 4, and probably
the Pi 3 too. (There's an issue with SPI on Pi on Debian Bookworm, but
it works fine on Raspberry Pi OS Buster.)
Yes, it runs fine on a pi3b, but the pi3b is dragging its tongue on the
floor, where the 4 core pi4b is right at home.

6 available, for $60.
But that also needs a triplet of 7i42TA's and 3 very short 50 pin scsi
style cables, the fpga is connected directly to the fpga, the 7i42TA are
its overvoltage protecors/adapters to the 5 volt world. The 7i42TA's
also supply the very convenient screw terminals to wire it to the
machine, 10,000% easier to wire.
You have to flash one of the SPI firmwares on it, using mesaflash.
That needs a pc with a std parport, see the fine manual for how to go
about reflashing it if an spi enabled bitfile is in it.
