Depends when the Minolta flash was made, I think they changed hotshoes in the mid eighties.
Question 1 to ask yourself - Does it physically fit your flash? If not, then no point going any further.
Question 2 to ask yourself - If it fits physically, how high is the trigger voltage. This site
Photo Strobe Trigger Voltages claims that your flash may be around 2-7 volts which SHOULD be safe. (I'm not making any guarantees)
Comment 1 - If it does fit and you want to use it then either measure the trigger voltage or purchase a Wein Safe-Sync or equivalent.
Hope this helps
