Re: [TUHS] AT&T / Teletype DMD 5620 Emulator

Hello folks, I realized I should mention this here on TUHS, since it is likely of interest to at least some of you! I recently wrote a DMD 5620 emulator, currently available on Linux and Macintosh, with Windows support coming soon. Here's a brief demo of the Mac version: https://www.youtube.com/watch?v=tcSWqBmAMeY I wrote it because DMD 5620s are becoming incredibly rare, and showing them off in person is quite difficult nowadays. This emulator is using ROM version 2.0 (8;7;5) dumped from my personal 5620. If anyone out there has a DMD 5620 with an older ROM, I would be incredibly grateful if you could dump the ROMs. I'd like to find versions of 1.x (8;7;3 or earlier); so far I've had no luck. The main reason I'm interested in older ROMs, besides pure preservation reasons, is that the 'mux' and 'muxterm' system on Research UNIX V8/V9 is hard-coded for the 1.1 ROMs. It doesn't work with the emulator without significant tweaking of the source. It DOES work perfectly well with the DMD Core Utilities package for the AT&T 3B2, however. All the best! -Seth -- Seth Morabito Poulsbo, WA, USA web(a)loomcom.com
