Conitec GRIP and GRIP-Color

Hi all, Some time ago I've got from a friend a defective ECB Bus Card named GRIP-4, that's a ancient Z80 based graphic display controller Card using the MC6845/HD6345 CRT Controller made by the (still existing) german Company Conitec in the 80s. Additional I've got an empty extension PCB called Grip-Color..the for color needed Memory, shift and palette registers. I've phoned the CEO from Conitec in the meantime and he will send the paperwork regarding the GRIP-4 that he still could find to me for scanning, unfortunately he couldn't find anything for the Grip-Color card. I have a running ECB bus system with an REH-CPU280, an Z280 based System that could run CP/M-3 and UZI280, has an FDC on board and an IDE Interface with an 128MB Flash disk, I whish to extend that with the GRIP Cards.. Is here someone that could please provide some Information related to the Grip-Color Card? I think I've repaired the GRIP-4 in the meantime (still have to connect an CRT, just replaced the FBT [different Model and Make] in the Monitor that I want to connect), but the oscillograms are looking good. I whish complete the Grip-Color card, any helpful information is welcome, even a picture where I can see which ICs are soldered in. https://www.z80cpu.eu/mirrors/oldcomputers.dyndns.org/public/pub/rechner/co… Thanks in Advance, Holm -- Technik Service u.
