My current thinking on my hard drive upgrade: A small square board bolted to the fan grate on the back left. All those 3b1s out there are proving you don't need the left fan. In the 7300s its ok, but in the 3b1 is produces dead spots in the air flow and two fans actually makes it worse. My idea is to just let the connectors stick out the grate. There will be 6 connectors: 1 hard drive 34 pin, 4 hard drive 20 pin connectors and one 34 pin floppy tape connector. There are four hard drive connectors so that you can take the internal drive out of the machine to reduce the load on the power supply. As I have mentioned before in other postings, the system software already supports two hard drives. I intend to re-write the gd driver to be able access two more hard drives, one floppy tape drive and maybe one more floppy drive (AT high density). Convergent had a lot of trouble with this last one, but I've seen it done before, so I think it's possible. BTW, does anyone have specs or practical experience with ST-506 hard drive data cables (the 20 pin one) as far as maximum length goes?
