[comp.sys.amiga.hardware] Repeeeeeeeating keys problem

dac@prolix.ccadfa.oz.au (Andrew Clayton) (01/25/91)

G'day.

I'm almost sure I've seen this question posted before, but I've never seen an
answer.

My Amiga has recently developed a sporadic problem with its string requestors.
What happens is that I'll press a key, and it will just REPPPPPPPPPPPEAT very
very quickly. Pressing another key stops the repeat, but 'backspace' seems to
take forever to start deleting characters (Amiga-X works instantly though).

I mostly notice this happening in the string requestors for Cygnus Ed, [since
I use CED a lot] but I've seen other programs do it (Quarterback,
Mandelblitz).

I have an A2500 with 2090a disk controller, GVP 30Mhz 68030/68882, 4Mb 32 bit
memory, 4Mb 16 bit memory on an 8Up! board, 1Mb chip, Fat agnus, ASDG dual
serial board, and a 'cherry' keyboard (with the normal key sized function
keys, and red topped 'Amiga' keys.) I'm running under Workbench 1.3.2 with
MyMenu, PopupMenu, Popcli, Arexx, Ced and some AmigaUUCP stuff
running/resident.

Any hints as to what my problem may be?

I had the same problem when I started using SetCPU to put my ROM in 32-bit RAM.

The solution is quite simple. All you have to do is use the KEYPATCH option with
SetCPU. The problem is with Cherry keyboards. (Me thinks it's bad serial frequency
on the keyboard data transmit line.) This fixed my problem about 6 months ago
and I lived ever happily after.
