I am looking for experiences of anyone who's worked the HC11A8 uC made by Motorola in general, and any experience with hardware development systems (in circuit emulators and the like) in particular. I'm considering between a Motorola model (which can emulate most, if not all of the Motorola chips by changing the "emulation unit" attached to the mainframe), and an Applied Microsystems Corp. EC 7000 microcontroller emulator, which only does the 68HC11A8 uC. By price the two units seem nearly the same (around $10K US), but if I can emulate more than one processor at a reasonable incremental cost (the Motorola emulator box for the 68HC05 chips is $2K US, so for $12K US I'd have an emulator for both the 68HC11A8 and the 68HC05C4/C8, while with the AMC box I'd have to buy *another* emulator from who-knows-where in order to work with the HC05C4/C8 chips as well as the 68HC11A8) I've heard some pretty reasonable things about the AMC emulator and was given a look-see by a local company who's using three of them, but haven't seen or heard anything about the Motorola box, save what Motorola's told me. I intend to see the local Motorola engineers to take a look at their development gear before making my final decision. If anyone in net.land has experience with this unit (or the AMC, or some other emulator I don't know about) and could suggest things to look out for, or what's good about these respective units it would be a great help. Thank you in advance for any and all comments / suggestions. +-----------------------------------------------------------------------------+ |Timothy D.
