Edm identification

HI to all this is my first posting and im asking for any information on the following machine.
but first a little background.
20yrs ago i purchased an old edm machine manufactured by a company in southern uk called concept edm
it was an excellant m/c being a bench type and 10 amp power i was so impressed by its action so i found another one and bought that also well i think you can see where this is leading both m/c have now stopped working as the company stopped trading years ago i can find no help here but as thousands of these maachines were made and they were well made to last i feel certain some one must have information regarding their circuitry etc so any help would be appreceated.
sorry for the ramble and spelling
