Both numbers are nice round numbers in base-2 space. After some calculations I ended up with 512 * 384 resolution. Ping! I realized, I don’t have to draw all the pixel data from the memory. Even that 128 kB is almost too much for a thing that is supposed to be old-school. I had some 128 kB SRAM’s lying around which was about the maximum I wanted this thing to have.

I still wanted to be able to display 16 colors, but not with that amount of memory. The monochrome picture would be ok, but the memory required for a 16 colors was just too much. Monochrome picture would take 38400 bytes and 16 color (4-bit) image would take 153600 bytes.

Then came probably the biggest problem: Memory amount needed to display picture with 640*480 resolution.

They seemed a very nice solution for this project because of their speed and flexibility, plus they are old going back to mid 1980 (they are based on PAL’s which are from late 1970). After looking around and thinking of ways to implement the adapter, I dug up some old GAL re-programmable logic IC’s which I got from an old Cisco(?) router/switch/whatever it was and some that I had bought from ebay. After a lot of thought, 640 * 480 60 Hz seemed the best as it is kind of a industry standard and uses the lowest pixel clock frequency, 25.175 MHz, supported by standard VGA resolutions. There are many resolutions and frequencies that can be used. Next thing was to find out about signalling. And I also decided to cheat a little bit on this part of my totally old-school computer. Though VGA is bit too recent to be used in an 8-bit old-school computer, I decided that it is a good trade off between old and something still around. VGA is old too, but it will still be around many years. Composite-connection is getting quite old and there ain’t especially many monitors (or none?) supporting it anymore. VGA as a standard was quite obvious choice. Plus I planned to build the adapter in a way that it can be used separately from the computer itself. After some thought I realized: When I get even the CPU-board working, I want to display some stuff! So why not build the display adapter first. I first re-designed many things, like power, CPU-board, IO-board and so on (my old plans were around 10 to 15 years old). This week I had a bad flu and could not do anything useful so I decided to dig up my old plans for this project. My lifetime project: building an 8-bit computer using Z80 CPU.
