Hello to the group I just picked up a used Paragon II and have several questions... First, where is the backup battery located? I've read that the Paragon uses a long life lithium cell, but I can't l
As I recall the Memory Backup battery is located in the CPU chip. I don't recall there being an separate lithium cell. Not being familiar with the T voltage mod, can't say. However there is an intern
Unlike the original PARAGON (585) which used a 9V battery to retain memory when the PS was turned off, the PARAGON-II (586) has a microprocessor internal power cell which has a rating of 8 to 10 year
Gary, I was told that the 9v battery for the Par-1 is no longer available. What do you use instead? 73 Rick, DJ0IP Unlike the original PARAGON (585) which used a 9V battery to retain memory when the
Rick, When I had Paragon 1's I routinely replaced the 9-volt rechable batteries with Radio Shack 9- volt rechargeables and they worked just fine. Be aware that for the battery to recharge early Parag

The 9V battery used in the original Paragon is a standard 9 volt rechargeable battery. You know the kind that has 2 snap terminals on top. The Paragon II has an internal CPU battery system which I un
Hello Pete, Ref the Paragon II The Dallas DS1220y-200 mem chip on the RAM/ROM/RTC board at U2 needs to be replaced.... 73 Mike _______________________________________________ TenTec mailing list TenT
Thanks Mike... that confirms my suspicions. I'd also guess the Dallas time chip has an internal battery for the clock. Those Dallas chips seem to run forever. I'd wonder if anyone has opened one up t
Looks like Mike nailed it. $20 in parts to fix the problem. See the data sheet at http://www.alliedelec.com/images/products/datasheets/bm/DALLAS_SEMICONDUCTOR/70127784.pdf 73 ES DX, Gary -- AB9M Hell
Well now, I'm not too sure about that. without looking at the schematic, but I'd guess that this RAM/ROM/RTC has some sort of firmware installed at the Ten Tec factory. It's this firmware that gives
I wrote the firmware for the Paragon II. The firmware resides on the Microprocessor chip not the RAM/ROM/RTC chip. That chip contains all the non-volatile memory. The memory persists because of the b
I found Jameco has product in stock for $13 at http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_114260_-1 the data sheet says that each chip has a AABB (year year week week) date o
Pete - that should take care of it - I've replcd a few.... just be sure to look at the date stamp to be sure it's not old stock. I believe Gary had a good link to purchase that chip.. Good luck with
Gary, good find on the U2 chip - that's still a good price I've replcd a few........ Good luck 73 Mike W9IFR _______________________________________________ TenTec mailing list TenTec@contesting.com

In the mid 1990's Sun SPARC workstations were all dying because the batteries in these chips failed. When they did the ethernet stopped working, and since a 5 year old UNIX system with no ethernet i
