The first SLR, coming after the Minolta CLE rangefinder, which used the same TTL flash electronics and flash units. The Metz SCA 331 adapter shoe works with the X-700 and the CLE, and the Metz SCA 307A extension cord allows TTL flash metering with the flash off-camera as the OP wants to do. I've done that with both the X-700 and CLE.

According to the chart, the SCA 331 shoe works with the following Minolta camera models:

X300S / X370N / XD / XG / X300 / X370
X500 / X570 / X700
5000 / 7000 / 9000 / MAXXUM 5000 /7000 / 9000

(The Maxxum name wasn't used outside the US)
