GE Rangr and Delta S/SX radios were some awesome products back in the day. They are both basically the same radio, with the Rangr subcontracted to an offshore manufacturer and the Delta made here in the United States. Both use the same cables, control heads, power leads, microphones, etc. The Delta radio case is more traditional and square, while the Rangr case is somewhat streamlined and more artistic. I believe both use the same mounting tray, though.
Jim202 is correct in stating there are two different configurations of control heads and cables: The basic cable that used a simple control head (for up to 16 or 32 channels) with the programming in the radio, and a deluxe version with the programming "brain" located in the control head and it downloaded into the radio when power was applied. The deluxe arrangement worked with the alphanumeric control heads and also could control sirens, emergency lights, and may have a built in DTMF (touch tone) keypad. The deluxe heads offered up to 432 channels in banks of 16 channels each.
Don't confuse the original Delta radios with the Delta-S and Delta SX models. The original Deltas came out in the early 80s and were crystal controlled radios, replacing GE's venerable Mastr II series. For you Motorola fans, compare the original Deltas with the Mitrek. The S and SX versions were synthesized (i.e. programmable) and they were offered in the late 80s up through the mid 90s. The SX version is a wideband unit capable of covering a larger frequency spread. The GE Delta S and SX compare to Motorola's Maratrac series.
My hunch is you have the Delta S or SX series, as they were very popular models and the ones most likely to be recently replaced by a customer. Provided everything is there and it works, you have some VERY GOOD radio equipment that should work in the amateur market for years to come with technical performance much better than any traditional mobile ham radio on the market.

For model information, features, etc. your best point of reference is the Hall Electronics website. Hall's was a GE Mobile Communications dealer/factory repair center in Columbus Ohio and they've put almost all of their technical info online. You can find everything you'd ever want to know with some digging. Go to
Hall Electronics, Inc. and click on GE Tech Info in the upper left hand corner.
The Rangr and Delta series was available in 60 and 110 watt VHF low band, 40 and 110 watts in VHF High Band, and in 40 or 50 watt and 110 watt versions for UHF. 800 MHz radios were available in conventional and EDACS trunking formats at 10 or 35 watts, and 300 milliwatt VHF High Band and UHF mobile repeater (PAC-RT) systems were also packaged in Rangr boxes.
If you want someone to do your programming, your best bet is Andy Brinkley at Brinkley Electronics in Wallburg, North Carolina. Go to
Brinkley Electronics Home Page and click on "Company Info", then click "Contact Information". Tell him what type of radio you have and what you want done, and get a service authorization number. Ship it to him and it'll come back right the first time. I've used Andy several times and found him excellent to work with.
What a shame GE isn't in the two-way business anymore. They made some great stuff back in the day.
Hope the info above helps you.
