WTB: Memory card for PCM80

[vintagesoundguy]

Hi all I am searching for a PCMCIA Type I card for the Lexicon PCM80 memory slot. Apart from the odd new card for around $88, all I get in searching on google is bazillions of card 'adaptors'. This got me to thinking, can you use a card adaptor with an SD card or something similar - it certainly would be cheaper. If this is not an option, anyone out there have one to sell? I believe they need to be 1mb type 1 PCMCIA.

Blessings
