Hi, I picked up an Acorn RiscPC 600 base unit the other day, my first Archimedes- type Acorn machine. Anyway, I have a few questions. Perhaps someone can point me to a decent web site about the Acorn machines? - I'm assuming the RiscPC 600 uses an Archimedes-type mouse. This should not be a major problem, as a simple pin-to-pin adapter should allow a three- button Amiga mouse to be connected. - Can I use a PS/2 type PC keyboard, or is a custom Acorn keyboard needed? - Before powering it up, I want to remove the hard disk and create an image file of its contents. The CD-ROM drive needs to be removed in order to get to the hard disk. I can't see how to do that. Any ideas? -- Mark
