Windows XP? we can install JAVA 1.8.0_152 as the last JAVA version that will install.?
With this you can run just about any version of JMRI.?

JMRI 2.14.1 is very dated and will not have many of the newer decoders in it.? It is not worth your time and effort..?

You can get? JAVA SE Runtime 1.8.0_152 (offline installer) from this link which is the older versions of JAVA.
Disregard the "doom and gloom"? messages you get during install.

I used this setup for quite some time before upgrading to Win10 on this 32 bit IBM Thinkpad R60 laptop
and a T60 running 2gb of ram and 2Ghz processor. I still use it with Win7.

Here is a thread on similar subject :

/g/jmriusers/message/155999

Other option is get newer, cheap laptop that might be 64 bit.? But the XP box will run JAVA/JMRI just fine. The good point is high memory count.
The T60 even ran Win10 for a while without major issue.? With XP it was just faster.

The DB150 can not read decoders, only write.? The PR4, when used in Standalone mode, can read/write to decoders.

You had better target the current TEST (4.17.4) version of JMRI with the PR4 as previous versions had issues with the PR4 and PAGE mode
programming that could cause decoder corruption.?

I am a new kid in the JMRI neighborhood. I've downloaded the manual(s) but have not yet downloaded any of the software pending the answers to the following questions.

First, about my computer setup: I have an old (slow) Dell laptop running Windows XP with lots of available memory. Your info says that Java 1.6 should be used with XP. I have Java 1.7.0. Your info also says that I should use JMRI version 2.14.1 and DecoderPro 3. I'm assuming that these last two are available on your website.

Now the questions: (1) Is Java 1.7.0 alright to use with your software? I hear that all Javas are backwards compatible.
(2) Can I use any updated versions of your software and the (latest) DecoderPro 4.x?
(3) If I must use JMRI 2.14.1, can I use it with DecoderPro 4.x?
(4) Given my old hardware, do you suggest that I just chuck it and buy a newer,cheap laptop computer?

JMRI and DecoderPro are one and the same thing.

You can run the latest JMRI 4.x.x version with Windows XP, but you need to manually install an earlier version of Java 1.8 on your PC (you can't use 1.7.0). The procedure is explained at:

(JMRI V2.14.1 is very old and is pretty much useless for most modern DCC decoders.)

John:

The single largest issue with XP now is a lot of it's parts, like Explorer, can be an issue...

The advice on where you need to be and might be able to get to with JMRI... it's version and the Java needed to run it is good.

Where you might have a problem is will XP let you download the Java version or JMRI version needed. Do you have access to another machine with newer Windows (or a Mac) that would let you download the offline version of Java and then "sneaker net" it onto the laptop via a USB stick?

If so then I think we can get you up to date.

??? My train computers are old desktops, NOT connected to the net.? I update DP with a thumb drive.? I see no reason a XP computer could not be used that way.

Not going to get into the technical ups and downs about running JMRI on winXP...? I have run it on an older XP laptop fine... however, it was so slow booting and bringing up the software... not to say any internal processing (which was sluggish by todays standards)...? ? I bit the bullet and am very very happy I did.??
I bought a used HP laptop,, running Windows10... for little over $100? ?it was older generation,,speed and processor.. however it was superfast for booting and running the JMRI software... well worth the $100...? plus most newer DCC gear was very likable to the Windows10 platform....? my suggestion... get a newer Windows10 laptop... even its an older one... it will be much better that the WindowsXP operating system....? ? ? ?just my opinion...? joeg

Don't forget that JAVA for an XP computer is restricted to version 1.6 (?)
so you are forced to run older versions of JMRI. The newer Win-10 machines
will run the new Version of JAVA and you can update JMRI with no problems.
XP while a good operating system is getting harder and harder to find
support for evolving software.

As already mentioned early in thread, it's possible to install Java 1.8 on XP.

With more time than brains. I blew away Win7 on a Thinkpad T60 2GHZ / 2GB ram and then went thru the Windows XP installation. I then got JAVA 1.8.0_152 (offline installer) from the link I had provided and JMRI 4.17.4 from JMRI Downloads.? Copied them both to a mem stick as the XP's? Internet Explorer would not connect to most sites.

The install was without a glitch and JAVA installed without a whimper. JMRI? loaded just fine. Downloaded the driver for the PR4 from Digitrax (using IE ??).
Everything works fine in both PR4 Standalone mode and/or attached to my DCS50.

I had more problems finding a browser that works under Windows XP.

The T60 starts up faster that another 32 bit system running Win10.? It is ready to work while the Win10 system is still churning away.

Marc

Much to my surprise, this Windows XP Sp3 install is going thru 77 updates at this time.

Looks like there is still some support for XP? from Microsoft? : - )

Marc

You can do the offline download and install of Java 1.8 up to version 153 or
some number close to that. Somebody posted the correct number not too long
ago, which was the last version that installed ok on Win XP.

HI Marc,
I think that by using this paleo computer and operating system you may be building a system that you will never be happy with.
I have a Spectrum ZX81 that still boots up but I wouldn't try to use it for anything serious.

John:

I couldn't think of anything I could actually do with my Sinclair even when it was new... even with extra RAM... The Heathkit H-8 was much better...

An XP machine is fine for JMRI and the RR if that's what you have and a reduced chance replacing it... I know of a couple in the circle of MRRing friends.

And yes I still have my Sinclair...
