Ok, here's the full story : I have had my Amiga 600 since 2001 and have added a few bits over the years: - 2.5" 4GB harddrive (I can't remember the make and model at the moment) - 1MB RAM (in trapdoor underneath) I also have a 4MB PCMCIA RAM card which is rarely used, and 2 external floppy drives (one doesn't work), with only 1 connected up. I haven't upgraded any of the kickstart or ROM chips, they are the same as when I bought it. I run WB2.05 (and am happy with it) with kickstart 37.300 I don't know the board revision number off-hand but I can find out if required. My harddrive used to power down (powersave?) after not being used for say 20/30 mins and happily power-up again whenever I tried to access the drive (via WB or via AMOS BASIC). However, around April/May this year the drive started to randomly power down and then, usually, almost instantly power back up again but WB nor AMOS could access the HD. Any attempt to do so would freeze WB or AMOS. I figured (as you would) that my harddrive was playing up, so I copied all the important files to 26 floppy disks (fun!) - 880K each, you see. A mate (Scuzz, who owns the http://www.commodore-amiga-retro.com website and the equivalent yahoo group), and die-hard retro (especially Amiga) enthusiast offered to use my HD as a slave and copy the files,

from floppies to the HD, including Octamed 5

as best he could, to his PC and burn them to a CD for me. In the meantime I got myself another HD, which happened to be the same make as my last one, with WB3 on it (it has a Locale folder, files I didn't see on WB2 and a 68040.Lib file). This new HD has exactly the same problem :( I popped along to www.amiga.org and posted my problem up there and peeps then suggested it might be a flaky PSU. I got myself an A500 "heavy brick" model (AFAIK it's compatible and gives more power if required) by chance (I was planning to get another A600 PSU) from www.amigadeals.co.uk Everything appeared to be fixed. However, my A600 was running hotter than normal. I have always put a plastic pen above the air vent bit at the top of the machine (by the F1-F4 keys)

d it used to always be cold. With this new PSU it was warm and the underside of the Amiga 600 was hotter than normal. I posted my concerns to either Amiga.org or CAR and then someone suggested that it might be a faulty resistor. He claimed that the A600 PSU didn't have enough power to supply the machine with a faulty resistor (thus causing the HD to shutdown temporaily) and that the A500 PSU did, and the extra draw from the board (caused by the faulty resistor) could be sustained by the A500 PSU, thus causing the extra heat. (I could look up what he said and quote it tomorrow, if it helps?) Phew! I hope that all makes sense.
