xanthrou Posted November 21, 2021 Share Posted November 21, 2021 (edited) Wonder if THAT's possible to extend the VERA's VRAM externally. Edited November 21, 2021 by xanthrou Quote Link to comment Share on other sites More sharing options...
Scott Robison Posted November 21, 2021 Share Posted November 21, 2021 VERA would need more address lines and data lines, and given what we've been told about it's limitation, I think the answer is no. But I Am Not An Expert(TM). Quote Link to comment Share on other sites More sharing options...
BruceMcF Posted November 21, 2021 Share Posted November 21, 2021 A RAM expansion similar to the C64 REU would be possible, since it's possible for expansion cards to take over the bus. Quote Link to comment Share on other sites More sharing options...

A (preferably single cycle) DMA transfer into or out of Vera would be the closest you could come, as expanding the SPRAM module built into the FPGA is not going to happen. 2 Quote Link to comment Share on other sites More sharing options...
