Survey data collection software for the HP 48 GX. This includes 1 Topcon FC-48GX Surveying card, Version 4.2 with 1 256k GX ram card and a home made key board overlay. The Topcon card is the same as the TDS survey card. It has just been packaged for resale by Topcon. All work fine as I just had them in a 48 to check them out.
Please ask if t are any questions. Buyer is responsible for shipping fees of $4.00. Good Luck.
