I concur with Dave McGuire. It's a Z8002 control computer, with some healthy RAM and ROM, that runs some kind of studio video editing workstation, with its own display. What it can do by itself, is unclear. It's certainly *not*, some kind of general purpose computer that loads and runs text or numeric programs. recycledgoods.com, seems to have some ADO 1000 stuff, like that big video processor that Dave mentioned. Someone with technical Z8000 interest, would have to dump and disassemble the ROMS, and disassemble. And, dump that diskette - but my guess is, it's full of scripting files not "code". And they'd have to second-guess the floppy controller and the video controller, to have fun with the screen and floppy. Extra credit: communicate with five UARTs with FIFOs (character memories). And of course, figure out how to replace the keyboard (and whatever else is on that keyboard). Maybe some 1990's TV studio techs could provide some assistance or direction. So the guts of it, are late-80's chip-techie fun, for those of us who do that stuff. about "nothing appears on the screen". It may need to have a keyboard attached to finish its ROM bootup. Or maybe the brightness needs to be turned up. Or maybe there's video output on the video connector in the back. I'd say, enough Web research on Ampex video studio equipment from 1990 would find some information. Plenty of that stuff in trade-journals about TV studio production. And recyclers. I found all that, with "Ampex ADO 1000" web searching. Hey, one of my favorite Web sites is on this! https://deskthority.net/viewtopic.php?t=12256 Ampex ADO 1000 They are a little focused on the keyswitches .... https://www.youtube.com/watch?v=0rxuU_TaFiw Ampex ADO-1000 Digital Video Effects - promo, but there it is! Maybe it made its own promotional video? Funny. So it's likely a thing, for people who want to collect vintage video production equipment. There's actually a history of microcomputers in video production, all the way back through S-100. Cromemco (those Dazzler people) became a producer of video editing equipment in the 1990's. There's an Australian guy who was early in digital video editing, including some S-100 stuff. Thanks to David K for showing off his find, and Dean and Dave McGuire for further IDing this box. I have too many other things myself, to acquire this. Regards Herb -- Herbert R.
