in parallel to my other projects I'm currently trying to choose a graphics card for another retro project.
But: I find it very difficult to classify ISA cards.
I have a mainboard on which (according to the manufacturer's information) there is a Chips & Technologies CT W65545AE3 (written on the chip itself) card. According to the manufacturer, this should be a Vesa Local Bus connected card. It has 1MB of memory.
This is what the mainboard manual says:
Controller: VL-bus C&T 65545 VGA controller with Windows accelerator * Display memory: 1 MB on-board DRAM * Display resolution: […]
Controller: VL-bus C&T 65545 VGA controller with Windows accelerator
* Display memory: 1 MB on-board DRAM
* Display resolution: Supports resolutions up to 1280 x 1024
* Non-interlaced CRT display up to 1024 x 768 with 256 colors
* Flat panel display up to 640 x 480 resolution
* Support True-color and Hi-color display capability
* Display output: DB-15 VGA connector, 22 x 2 pin header general purpose flat panel display connector
Target purpose of this system will be a DOS only machine. No Windows - only native DOS.
My questions would be:
Shall I stay with the onboard VGA card?
Or shall I add another ISA graphics card?
The only upgrade options are ISA cards - the system doesnt have a PCI Bus!
If I should go for another card: which one should I use when sticking to DOS only?
