Hello and a couple of questions

[Thomas]

From the screenshots it has Workbench 2.04 and Kickstart 37.299.

1) I intend to add a 2.5" 180MB HD in the internal slot, will this work? If not what do I need to do to be able to do so?

You need Kickstart 37.300 or 37.350 to use a HDD. The 37.299's IDE driver is not able to boot from HDD. When changing Kickstarts, you should consider to upgrade to the latest version (3.1 / 40.63).

2) I need to be able to use CrossDos to read 720k PC formatted disks (in order to copy compressed adf's at work) does my workbench have this? If not what can I do to be able to do this?

Insert the Extras disk, open Extras/Storage/DosDrivers and run PC0.

Bye,
Thomas

Does this therefore mean that the HDD would be recognised, you just cannot boot from it (in other words I would need to use the workbench floppy to boot workbench to use the HDD)?

Probably, yes. I don't know exactly (never had an A600 myself). See this page for details: http://www.gregdonner.org/workbench/wb_205.html

Also, how hard is it to actually change the ROM as I am not good at soldering things at all.

The ROM chip should be in a socket. You should be able to lift it easily with a screw driver. Just make sure you do it equally on both ends so that none of the legs is bended.

Edit: see this picture: http://www.amiga-hardware.com/download_photos/a600mbrev1_big.jpg
On the left bottom the big socketed chip is the Kickstart ROM. You can see that the third line printed on it reads "(c)1991 V2.05 (37.300)", this is the ROM version.

Bye,
Thomas
