In the US under the FAA system there is only one 373 type rating good for -100s through -900s. Most of the 300s, 400s and 500s have glass cockpits, some of the old Southwest aircraft didn't to have a common cockpit with the 100s and 200s. But eventually even SW went glass.
Pan Am does have a 300 sim also according to the latest FAA list. Whether it is glass or not you would have to check. Also Global One Flight Training in Sanford, FL.
