Hello, I purchased a used Tascam MX-2424 recorder that is missing the TL media card. I would like to update the firmware to the latest version but I need the card. My question is what type of media card is this? If this is an older PCMCIA type of card is there a substitute media card that would work? It also looks like a possible compact flash type slot. If possible I would like to "NOT" have to contact Tascam about this. I really appreciate any help with this.
