With the old style Cherry keyboards you just can't run the ROMs (and the associated keyboard read routines) at 14MHz. The solution is to remove the 'J1' jumper on your Processor Accelerator. This allows the ROM accesses to be handled at 7MHz at all times, rather than running them at 14 when the processor is running at 14. : : Also, when activating various CLI's the output gets redirected to : the newly activated one. : Do you mean while the keyboard is in BOZO mode? (BOZO mode is a technical term for the problem you were having...) :) That would not be suprising, since the keyboard is still spitting out all those characters. If you mean something else, let me know exactly what's happening. I haven't seen any CLI redirection problems at any speed... : : This is the only problem that I saw with the accelerator. : It worked fine at 7MHz. The system I was using was a : 3meg 2000, w/bridgecard, hard drive. : : I'm still looking for a good accelerator (with 68881 would be nice). : Any suggestions will be appreciated. : You might try the Processor Accelerator... Again. It works very nicely on almost any machine. : : drjerrard@trillium.waterloo.edu -- -Bill Seymour ...tektronix!reed!percival!agora!billsey ...tektronix!sequent!blowpig!billsey Creative Microsystems Northwest Amiga Group At Home Sometimes (503) 684-9300 (503) 656-7393 BBS (503) 640-0842
