I have three items I no longer need.
The Keyspan USA-28X is the dual serial port version and is going for $70 (check out DealTime - Keyspan (USA-28X) Serial Adapter)or more on the net. I'm asking $35 for mine + $2.50 s&h.
The serial cable was purchased from Charles Turner at stellanova and is 12' long. His cost new is $18.50 + $4.50 USPS priority shipping, I'm asking $10.00 +$2.50 s&h.
Also a home-built, and tested, 50' LX200 GPS data cable. This is not shielded cable but is constructed from standard telephone cable. I have used it on my own LX200 GPS to update comet and asteroid ephemerides. I'm asking $25.00 including USPS shipping.
PayPal is preferred, with no surcharge, or I will accept Money Orders, Cashier's Checks or Personal Checks. The latter three methods of payment will delay shipping until the funds clear my bank.
All items are in very good to excellent condition. I apologize for not posting photos but my digital camera is set up and attached to my scope for Mars.
Thanks for looking!
