Prior to removing a burnt ROM, you can use the monitor's 'C' compare command for verification.
e.g. C <src> 8000 <num_of_bytes>
The programming speed is relatively slow because (from memory) the burner is set for the bog standard 50ms write pulses.
For a 4K ROM the duration is (4096 * 0.050) about 3 minutes 25 seconds.
The duration of these pulses on this programmer is set by hardware.
Faster programming is accomplished by smarter programmers using a combination of shorter programming pulses and content polling to see if the bits have all been burnt correctly for each byte before progressing to the next.
