The Receipt printer #05-0009 has been replaced by a newer model printer. The printer #05-0009 is repairable, around $100 - $250 depending on what’s wrong with it. The conversion kit to upgrade to the new printer is around $1000.
The dial up EIC #05-0053 is still available, they are pretty pricey, and list price is $1933.00. The part number #13-1137 is a recon part number. The last used dial up EIC I sold, I sold for $750 so they are worth their weight in gold. The EIC's are also repairable, but can get pretty expensive. I don’t think dial up is going to be around much longer, you might want to think about going to high speed internet.
