Had the 60ii since 98. Paid 800 for it way back then bone stock with the bottom row of pads damaged.
Since then I've upgraded it with Marion SCSI, +4db output boost, & 3.10 O.S.
The 60 in the middle, I just bought 2 weeks ago from Craigslist. Got it for a steal of a deal. Originally it needed a new disk drive and os upgrade from 2.14. It also had an old ram hack memory expansion that caused problems. But it did have a Marion SCSI to my surprise.
The 3rd 60 on the end I grabbed in December of off craigslist for a deal as well. It was & still is in kinda ruff condition. It had/has some rust and corrosion , but was functional. Got the metronome fixed & also the right stereo channel. It came with 3.14b Os & memory expansion..but no SCSI.
I swapped the OS chips from this into the middle Mpc. I also pulled the disk drive/memory expansion and installed in the middle Mpc.
I'll probably put a gotek USB & upgrade memory & OS in the 3rd 60. Then sell!
