I exclusively used an emulator for development. Motorola was not interested in selling erasable EPROM parts. Not only were they extremely expensive but some (PLCC, for example) were not guaranteed to meet specifications. Instead of paying $100 for one PLCC part for testing it was cheaper to use up a few $4-5 OTP parts for final testing. Best regards, Spehro Pefhany --"it's the network..."
