Moving Combo Disk Boot Loader (CDBL) Solved
Posted: April 19th, 2019, 6:25 am
I'd like to store the Combo Disk Boot Loader (CDBL) in ROM on my 8800c and AltairDuino.
The only HEX file I can find for CDBL locates it at its execution address (4C00h) rather than its storage address (FF00h)
I can change the load addresses in the HEX file but how do I recalculate the checksums?
Got it!
I found a website that calculates the chcksum on individual lines in the HEX file. Since there aren't many lines, I copied and pasted them
one at a time into the calculator and got the correct checksums. Now all my repros have the same ROM configuration.
