The Braille Lite 18 has no USB ports, and has no on board place for any kind of card. It uses serial ports and, I thin, its own proprietory paralel cable for printing. You will need to use hyper terminal or some such programme to copy files between it and the PC. It would not work as a drive in windows explorer so copying files onto it would not be simple. It was fine for its day, and I loved mine, but it is 20 year old technology. You need to decide what you want the machines to do, and find out from the sellers whether they will do this for you. Neither of them will run Sibelius or Goodfeel or anything like that. They would both work as braille displays for a PC, not sure about Mac. __________ Information from ESET Smart Security, version of virus signature database 6813 (20120120) __________ The message was checked by ESET Smart Security. http://www.eset.com If you wish to unsubscribe, send a blank message with the single word, unsubscribe - in the Subject line to: sib-access-request@xxxxxxxxxxxxx
