I¡¯ve done the ¡°make program disk¡± and ¡°load program disk¡± and it works a treat. I also converted an 8510X to 8510C. Someone mentioned awhile back that you couldn¡¯t take a program disk from one serial numbered machine and do a ¡°load program¡± onto another 8510 as the programs contained serial number data. That doesn¡¯t appear to be the case.
The 8530 to 8510 may be a different thing, though, as there¡¯s a PROM or EPROM specific to the 8530 on the security key board. I don¡¯t have an 8530 so I can¡¯t give it a try.

I have an HP floppy with the 8530A FW V 1.60 and an 8530A with the 8510C FW loaded. I would love to get a floppy image for the 8510C FW so I can switch between the two.
As far as I understand the 8510C On-Site Service Manual (08510-90282)
page 9-20: Making a Backup Operating System Disk
This function is intended exactly for that purpose.
Function 19 is "Load Program Disc" which I assume does the reverse.
Of course I have never tested this yet.
So you should be able to backup your 8510C and then load the 8350A. But
do test your disk somehow as mine are all old and shaky.
