Irish Horse Racing Test card (McCorquodale)
The McCorquodale test card was produced to test compatibilty of the McCorquodale chipset in Telecom eireann cardphones. What is very interesting about this test card is that it was encoded with 50 units of credit. The Irish horse Racing design was simply used for aesthetics purpose.
The McCorquodale chipset was never seen on any public issued Callcards.
