My design is around 8k LE but it is a full VGA - you might look at the original graphics gremlin MDA design to get an idea of the minimum necessary for a text mode.

I have a VGA core, which works on the graphics gremlin. This is for debugging that core but also for expanding beyond what the Gremlin can do - think of it like connecting a motherboard to a rapid prototyping system that has different kinds of memories and an astronomical gate limit. :)

No differential signaling today, Rue.

Altera's HSMC has 3 banks:
Bank 1 connects directly to gigabit transceivers, those can't be used as GPIO.
Banks 2 and 3 connect to standard FPGA I/O, some of which could be configured to be differential across paired pins.
I am using banks 2+3 as level-shifted standard I/O, and speaking ISA bus.

Yep, finally building it to test the VGA core so it can target both the original and HDMI version.

it'll do that when DNS is down but IP is working fine

this is the part where I'm reminded why a stainless steel stencil is worthwhile

Mouser has mine back to 2015 but this is a great idea - I doubt digikey does the same!

I have a couple monitors wall mounted to save space

oh, you thought it was a vitals monitor because it's wall mounted?

no this is just how steve's games looked
