Just joined this group so Hi All....I am an Amiga fan from way back but went to a PC some time ago now...a friend has just given me a 1200 with a 1 gig 2.5 hard drive and rom 3.0 .... now... the hard drive has packed up...(to long in the previous owners shed I guess) so what is the largest HD I can install without to much fuss and can I run os 3.1 on a 3.0 rom 1200 ... I have my A4000/040 OS on cd from years ago and would like to install that on the 1200 ... this 1200 has a separate case with an ide cdrom/floppy drive and the HD in....goes like the wind ...after all these years it still boots in around 10 secs (or it did until the HD went down) ... love my Amiga and will be keeping it for sure.....sorry to drool for so long....all the best .... Regards Seb (In luv agin)
