Hello, everybody!
I need some help!
Two months ago I bought old Power Macintosh 7500 in rather good condition: no cracks, looks rather good. The seller assured me that it works fine. Instead of SCSI drive he installed Sonnet ATA 66 controller card with SSD ATA drive and ATAPI DVD-RW drive. 200 Mhz CPU card and 176 mb memory. With MacOS 9.1 it worked flawlessly and fast, at least on video.
When I received the mac, at the beginning everything was ok. But after 4-5 days of rare boots disk partition on SSD drive once crashed. I booted mac with MacOS 9.1 installation disk and had to initialize the SSD. After that, unexpectedly, I couldn’t install system on the drive: installation started, but after 2 minutes it stopped with no changes to the disk. The same repeated with MacOS 8.5, 8.1 and so on.
I bought used ATA drive to install OS on it, with no success.
I tried to pull out memory modules (there are 176 mb, all slots are taken), one by one, but with no success.
I got bluescsi v.2 and there was no success in installation too: system boots, but never installs, even from one disk image to another.
However I managed to boot my mac with bluescsi with the image of MacOS8.1 installed by Sheepshaver. With that way it boots and works but I still can’t install anything or even unpacking *.sit archives is not always successful. Though copying from one drive to another works perfectly. I.g. I couldn’t install MS office 98, but if I install it under Sheepshaver and then boot with that image my mac, MS Office works perfectly.
Where should I dig up? What it can be? CPU card? Mobo? Any suggestion are welcome!
