When I finished this I found that I'd essentially used the Tinycore instructions that I'd printed out from the web site,but changed the appropriate file/entry names where needed with regard to microcore (and obviously used a microcore install disc) At the end before rebooting I'd then used 'wget -c' to download the Xlibs,Xprogs and Xvesa gz files from distro.ibiblio site (address in post above) to tce directory.
After rebooting and getting a plain blue desktop I then 'Ctrl Alt Backspace' to stop X and get a cmmd prompt.
At prompt I used 'tce-load -w -i' to get wbar and jwm so that Id have a working desktop.
So the above would be a reasonable guide to installing Microcore.
It did help that I'd installed Tinycore a few times already !
The later bits of the above(and now I think of it,even using tinycore instructions) I picked up from the various responses to my original post.
I noticed also that once I install LXDE I could then delete wbar and jwm,although whether it would work just using LXDE without first loading wbar and jwm I dont know. Thanks .
