JR BIOS

Postby Chuckphd53 » Sun Jun 17, 2018 12:08 am

I noticed that at boot up I have seen a couple different screens on the Jr monitor. At least I think I have !!!!

So I wondered if the Jr had a bios change over the few years it was available.

Second: If there is, will the earlier hardware support the later BIOS if upgraded.
Lastly: does a later version of BIOS exist in file format to burn a new ROM:
