Commodore B256/700 with Graphic and Ultra Electronic 7000 Board
in [Commodore]

From: Boris on 5 Jul 2008 04:58 Hi everyone, recently I got a CBM 700 (as it labeled here in Germany) with graphic board and - most strangely - an internal "Ultra Electronic 7000 Board". As it turned out (got that hint in the "forum64"), this board emulates the 80XX series up to the 8296, but because it's pretty rare, there are no information nor disk images on the web. Can someone please help me with this? Does anyone know where to get schematics or the disk image for that board? Does someone happen to have one and could provide some help? Thanks in advance. Kind regards, B.

Fascinating. Is this a Commodore board or third-party? -- Cameron Kaiser * ckaiser(a)floodgap.com * posting with a Commodore 128 personal page: http://www.cameronkaiser.com/ ** Computer Workshops: games, productivity software and more for C64/128! ** ** http://www.armory.com/%7Espectre/cwi/ **

Sounds like maybe a bitmap graphics board (similar to PET's MTU visible memory) - never heard of an Ultra Electric, but a good place to start would be some of the Commodore B Series sites: http://ca.geocities.com/sjgray(a)rogers.com/index.html (the CBM II page mentions an external Graphics unit) http://www.wfking.de/ Here's the external board: http://www.wfking.de/hires.htm http://home.comcast.net/~shockley15790/onlinestorage/b128.html Good luck

Indeed, there are two boards in it: the originally external (and manufactured by Commodore!) graphic board AND the Ultra Electronic Proxa 7000 board, which, as I said, offers an hardware- emulation of the 80xx series. Not the software to use the graphic board is my problem, because it can be activated via switch and the manual can be downloaded on some websites, but the emu-board is what I'm trying to find out more about. Has anyone heard of it yet? Does anyone have it? Perhaps it was only distributed in Germany by the company "Ultra Electronic" (Cologne?) and was distributed under another name in UK or US? I need the software to start the board as it seems. :( Best, Boris

I've never heard of this. I'd love to see some pics. I have the "High- Speed Graphics" board for the 8000 series PETs and I compared to the 700 version from WFKing's site and they are very similar. The 700 version is basically the PET version with the power section removed. It is mounted in an external case and connected to the B-Series via a ribbon cable from the ROM socket on the board to a small cartridge adapter that plugs into the 700. Both versions use exactly the same BASIC extensions, the only difference being the SYS location to initialize it. The board contains 32K of dedicated ram that the GPU uses for bitmap memory. It's kinda similar to how the 80-column chip in the C128 works. Otherwise, I have no idea what the "Ultra Electronic 7000 Board" would be needed for... Steve Gray "The CBM-II Page" |
