Is there an XR4 manual anywhere by any chance? m ----- Original Message ----- From: Stephen Adolph To: [email protected] Sent: Sunday, February 26, 2023 1:37 PM Subject: Re: [M100] VIDEO - Dial-A-ROM for the Model T computers (and others)
Mike, XR4 did not have any "protect the user from switching an installed ROM" functionality. It just hard-switched. You can see that when you disassemble the utilities. I think it had a couple of flip flops on the flex-board that wrapped the RAM chip. But I can't say for sure. I don't have an XR4. I do have an XR1. aka EXTRAM.

Also if/when I order one of each will the shipping be combined? TIA, m On Sun, Feb 26, 2023 at 8:32 AM <[email protected]> wrote: I’ll be doing a video on it eventually.

Anyone have a demo for that weather tracker? Looks DOPE On 2/25/23 07:31, [email protected] wrote: Morning all, I just made this video live this AM. The DARs for the Model T computers have sold out already but my friend is making more. In this video we take a look at the ‘Dial-A-ROM’ a spiffy new multi-ROM for vintage portable computers. It was designed by the same guy who did the Backpack drive. First, we’ll learn how to use the Dial-A-ROM with the ROM images that come preinstalled on it. Then we’ll see how to add our own ROM images if we so desire. https://youtu.be/CejyLsI0HIw Jeff Birt (Hey Birt!)
