Re: [M100] Video adapter.

Congratulations, Steve. By now I know you've made the adaptations, using code from the disk-BASIC. (post on facebook 19/04) That comes very close to the description of a device we needed to output video to a modern monitor, that I posted a few years ago. And was flamed for it... Anyway, great

Re: [M100] Video adapter.

Right, it's because of the digital S-VHS players that first had it. The TI-99/4a has baseband video on its DIN connector, which was then converted to RF by its bulky RF connector. On Thu, 16 Apr 2020 at 16:13, C. Magaret wrote: > > Other 8-bit platforms used Y/C video as well, particularly the

Gotcha. In my case, I want to use it with an Arduino powered Altair emulator, as well as with the T-102. I did actually find an option board for the Altair-Duino that will work, but it's designed to be used inside the other device, not as a stand-alone terminal. So configuring it as such would

kit has a 4 pin header for serial data, and is tolerant to RS-232 levels but you need to invert the signal (there is a setting for that). You'd need to sort out 4pin header to DB-25.. or DE? you get my drift ;) On Thu, Apr 16, 2020 at 12:18 PM Tom Wilson wrote: > Does the kit just not have a

Does the kit just not have a serial connector, or is it a DB-25? (fun trivia fact... there is no DB-9. The “B” refers to the size of the shell, and the 9 pin D-Sun is axtually an E size. So a 9 pin port is DE-9. But since so many people say it wrong, manufactures just incorrectly call then DB-9.)

Re: [M100] Video adapter.

regarding the kit. The kits available don't have a convenient RS-232 connector. I redesigned the PCB to support a DB-9 connector. If you can wait, I'll have that ready soon. If not, then I think you can go for Tindie ($$$) or the source that Geoff cites on his site. On Thu, Apr 16, 2020 at

I have a few bugs to sort out. DVI works in an interesting way. MENU is always on the LCD. So, one goes into BASIC, issues SCREEN 1 command to use DVI. Then, as I understand it, to get to TEXT you would first go to MENU (on LCD), select TEXT and automatically be back to DVI again. I have a bug to

[M100] Video adapter.

As some of you may recall, it is fairly straightforward to access an 80x24 screen in CP/M through the use of the M100 serial port, and an external VT100 emulator. This device: http://geoffg.net/terminal.html is a great example of how to connect a modern VGA flat screen display to the M100.
