Re: Procedures for MS 250 V1.12 and some wishes for repurposing it
- Your guess is as good as mine about the 350 since I have never seen one. I do know from reading many of the messages in this group that the 350 does not use the same type of central processor chip and that means the firmware in its ROMs will likely be very different. Does that mean that the data in RAM is laid out the same? Well, it could be but I would bet against it. So I would expect that these procedures would not work exactly as I have written them but it is always possible that they might.
Be careful. In my case, I was not too worried about messing up my 250 since I only had a dollar invested in it and the only time I had invested was with reading hundreds of messages and a few files located in this group.
