Nascom / Lucas - Advanced Video Controller - Model B Issue C
Full colour card produced after the rescue of Nascom by Lucas Logic. This large card (10 by 8 inch) card held 48K of DRAM, divided into 16K per RGB channel. The red / green channels could be be combined into one green plane to give a memory mapped 80 column display for use with CP/M.
The AVC proved is an excellent high resolution card at a reasonable price point. Its high-res green mode gives a very capable display for CP/M.
This is the only example of a non-socketted board I have ever seen from Lucas / Nascom. Various devices are not present and only the PL1 video is present. It is believed this was a cost reduced board used to supply an 80*25 display in CP/M workstations.
