Question about really old EFJ 5300s ver 1.10.0

I've got some super old 5300s that have the 68HC11 cpu and there are some with rev 11.11 firmware and others with 10.xx Was there ever a way to update this by computer or was this some sort of JTAG or component thing? Is there a PCTUNE made for these relics?

Also I've some ARM based 5300s that have the 035-1800-410.05 logic boards.
File Format 5.5
DSP 0.1.23 up to 1.64
Hardware Version 0.1.2
Boot Loader Version "Not applicable" <-Huh??

So nothing for bootloader version. And nothing I can come up with seems to do update them. I've got express updaters and tried doing it from PCConfig.
Has anyone figured out either of these oddities? Is there a special version of PCC that lets me update these golden oldies. If I knew what I was looking for I probably already have it.

When I put the radio into firmware update mode and try one of the express updaters it times out communications error and there is a warning about it being version 0

Thanks for any helpe and sorry if this just turns out to be a short circuit between the headphones.
