"Are those things STILL around?"
Never really went away.
GE Series One, TI 305, A-B SLC-100 (many people don't remember that version), all of them are the same Koyo PLC and once it got a little long in the tooth, all of the partners dumped the product. So Koyo cut a deal with PLC Direct (now Automation Direct). But it never really went away completely, just the brand-label deals did.
