Hi Thomas,
sorry its taken so long to come back on your comments, but ... the good news is I seem to have most things working OK and that was using the A590 HD install disk.
Part of the problem I was having not only related to my lack of knowledge about Amiga DOS, but also I appear to have a mouse with a VERY sticky right button, hence when I "right clicked" to initialise absolutely nothing happened. Any way I now have a A500 complete with a 490M scsi HD and 2M of ram running WB 1.3 together with a KCS power board with 1/2M ram, battery backed up clock running MS DOS.
Thanks for your help, your thoughts put me in the right direction.
Ehmmmm now what can we do with this machine?
