Usagi Electric | The Ultimate DEC Rainbow and a PDP Question for You! @UsagiElectric | Uploaded November 2023 | Updated October 2024, 19 hours ago.
Our DEC Rainbow is a pretty neat little machine, being a fully triple boot system – can boot DOS, CPM or into VT100 terminal emulation mode. However, it was still missing some vital components to really turn it into the best of the best. First and foremost, the VR241 color monitor. We managed to get a Princeton Ultrasync to work, but it’s not what’s supposed to be bolted to it. Next, we were a little low on RAM. And finally, we were missing the best expansion of them all, the RD51 Winchester hard drive option. Today, we fix all three of those!
