Hi John, thanks for your thoughts ... maybe I should have been more precise: The Toshiba laptops (and the Compaq) claim compatibility with the M24's 640x400 mode, so rather than "Super CGA" I should have said "M24 compatible" video - or is even that too generi...

The 'dual-mode monitor' text on my page is copy-pasted from the Interrupt List: INT 10h / AX=BF03h, BX=0000h. If I was asked to hazard a guess, I'd say that it refers to the internal CRT on the Portable I / Portable II and the external monitor used on the Deskpro -- a greenscale ...

To be fair, I'm not even sure if the "Dual mode" monitor is even the monitor you're supposed to hook up to the Portable III's RGBI interface-- I'm just making complete wacky assumptions from the Personal Bulletin, because it seems to be the only way to connect an extra ...

It's worth mentioning that the "dual mode" CRT display on the Portable II was indeed capable of a 720x350 text mode as well as 640x200 graphics. An interesting search result came up from a 1994 book called "SCO UNIX in a Nutshell." Apparently the "vidi&q...

Then again, if the MDA implementation was just a basic workaround in the Portable III's "Super CGA" hardware while it was still in "Dual-Mode", why would it not support an external monitor unlike in the "Dual-Mode" setting? To avoid people from accid...

Well I'll be, 16.098240 MHz for a plasma display. Enough to handle a Hercules signal. I'm guessing that the signal for the monochrome mode comes from the 48MHz clock. If the MDA mode is NOT a separate part of the video board completely using a completely different sync clock, it...

I've been self-compiling mame on Ubuntu 17.10 and one of the things I've noticed is that mame doesn't have a dock icon. If you don't have a dock icon, the mame windows get grouped way down at the bottom of the dock and you have to scroll all the way to the bottom to get them. I...

The service manual mentions a "B000" page for Switch 7's "Monochrome Mode" that is not implemented anywhere in the M24's video hardware. I'm assuming that Compaq went a step further and implemented fully a MDA clone which lies separate of the internal video ha...

Hello and welcome helwie44, I'm not currently working on the Alphatronic machines. It's very nice to see someone who did lots of work on those machines here though. Eventually I'll continue to work on it (if someone else isn't picking up the driver), then I'll be sure to contact...
