On my side, I have two other questions:
- How expensive/difficult is it to have 8 banks of RAM versus just 2 banks. I guess it's a bigger memory chip with more pins, is that much more problematic to use? If not, why not 16, 32, 64 pages??? (just to push the cork)
six years after, i found this post
Twilighte card handles 7*16KB of rom bank like telestrat. But it can also handles 7 banks of RAM and almost 32 banks too because there is a 512KB SRAM on the board. It's not activated in the CPLD, mainly because, it's a bit slow to manage it with software code.
For example, for Orix (telemon initially), keyboard buffer is in RAM overlay. When we read a key, we have to switch to the ram overlay for each keys read.
Well, it's possible on Twilighte card, but as i said it's not activated because i would like to have a mmu instead, if i can handle it on the oric !

/me still thinks that having joystick and mouse ports could be awesome, would allow us to make other types of games.
Done also on twilighte card (joysticks and mouse). 3 ways to have mouse on the card :
1) Joystick port : plug a amiga mouse or atari mouse, and driver must be written
2) on joysticks port : with an usb to db9 converter (tom2 for example) and plug a usb mouse : driver must be written too
3) plug the usb mouse in usb port, and the hardware will return delta X & deltaY from the last access to the chip, (coordinates must be read from page 3) Driver must be written too
