AW: CGA card (Mitsubishi Electric) with 192K RAM?

The color output *appears* to be TTL level - or, at least, that's what it's using at power-on. It's not impossible, I suppose, for it to be switchable to some kind of analog mode, thereby giving more color depth. I'm wondering if it doesn't have some form of high-resolution bitmap mode for visualization, i.e. display construction would be processor-intensive and intended for static images/diagrams. I don't know if that really makes sense though because it would also imply having to switch the monitor - i.e. starting the machine with a CGA type display plugged in, then physically moving to something else later. On the back of that, I just found this thread too which refers to an identical board: http://www.vcfed.org/forum/showthread.php?48718-3-Weird-Video-Cards-any-ide… ... nothing there really "helps", but someone's comment about the medical field and a higher-resolution display via the RCA jack is interesting - that would at least get around the need to switch monitors (well, unless there was some special autodetecting analog/digital monitor that was sold to go with the hardware, I suppose). It's a shame that the hard disk in the machine is either snafu or has been wiped - the contents would have helped shed light on things. There's an EPROM as part of the video hardware; anyone know of a DOS-based util to poke at the contents and/or snarf them into a file on disk? It's possible I suppose that there might be some useful strings hidden away in there. cheers Jules
