Hi, I've been absent from the list for a few years. A combination of relocation for work, and other stuff going on. I'd not stopped altogether though. I have got an antenna on the new QTH, my Thunderbolt boxed up and running and some other test equipment sorted. Any way I randomly typed Odetics into eBay (UK) last week and a 365 GPStar Plus time source / GPSDO popped up as a BIN. It appeared to be brand new in the original box and complete apart from the antenna. I made an offer and won it for under $100. It turned up promptly and sure enough is NOS, the power connector has never been made off. It's all working, but being a 1995 model it has the Magellen OEM5000 GPS engine so has the wrong date due to the week rollover issue. Back in 2012 Arthur Dent tried a Zyfer 565 GPStar Plus EPROM in a later Oncore engined 365 and it all worked. Rob Kimberley confirmed that this was the only difference between the 1995 Odetics 365 and the current Zyfer 565. Back then I got a BIN file of the EPROM (thanks Arthur) even though I had no 365. I burnt a 27C010 last night and the 365 runs with it fitted, but as expected does not recognise the GPS. So tonight I dug out Oncore UT+ (R5122U-1153) to make a retrofit. Next step is to identify the connetions to the GPS module. I have some OEM5000 info and some probing should sort that out. I do wonder if anyone else has tried this and has the connection information already? Oh nd as a bonus I will have a spare OEM5000 to retrofit my fully loaded, including Rb oscillator, 325 SatSync (currently needs a down converter antenna which I don't have) so I can get that working if I ever get it out of the back of the garage.
