Keyboard auto-repeat for Dragon and Coco
Here's a great little keyboard auto-repeat routine by Steve Woolham. He sent me this little gem via e-mail the other day and asked me to post it here after I had tested it.

Re: Cumana disk system
Thanks for the posted CumanaDOS ROM but I would prefer a copy from your original. The posted copy has been around on the internet for a few years now and I suspect it to be an incomplete copy. That's why I was asking for the ROM dump in the first place.

Re: EPROM Programmer?
Can anyone make out the number on those chips? It looks like MCM687 something?
What about a 24 to 28 pin socket adapter?

Re: EPROM Programmer?
Thank you!
What chips were used for the Dragon 32 prototype? Could these be D32 compatible EPROM chips?

The top of the PCB is comprised of a socketed SAM chip (SN74LS783N), two smaller chips (SN74LS74AN, S...
