Kelly – have you been reading Don Lancaster's column in Radio-Electronics?
Apparently old car alternators make great stepping motors… especially if
rewound slightly (so that each rotor is independent, I think).
Of course, they're rather large 🙂 But super-high-torque, I believe.
The 68070 also has a subset of the 68450… dual channels. Burst or cycle
steal. Max's out around 3MBs/sec in wordmode. I've written DMA code for
it, but it's been a while now. On an OS-9 system with a Quantum drive,
people are getting 1.5Mbs/sec file transfers thru the OS. Pretty quick. A
friend has designed a 68340/video card, but hasn't built it up yet.
cheers – kev
