SuperAltair Card Development
Well, I finished the hardware development (in the computer) for the SuperAltair card over a year ago. I had to stop myself and finish the Altair kits first! After thinking about the SOFTWARE development time required, I've decided to scrap the whole thing and start over. The target price is $250-$350 depending on options selected.
Most of the reasons for the change are quality related, not function. The biggest change is the substitution of the FPGA and -several- AVRs with a 200MHz ARM computer running Linux. Don't even think about mentioning the irony of a 200MHz RISC computer doing the dirty work for a 2MHz 8080. The combined AVRs and FPGA were also about as excessive. The reason for the major change is to EASILY support USB, file systems, etc. The SBC is inexpensive, and will actually reduce the cost! RAM:
Now is the time to complain. No money has been committed to the design yet. |

RE: SuperAltair Card Development
How about allowing the upper 8K to be deselected so a PROM card can be used?

800x600 VGA output
I took a look at the 7300 and noted that the VGA support listed is 800x600. I doubt if there are many modern, off the shelf monitors with a native resolution that small. An 800x600 output will appear in one of two ways on a modern display: scaled up (looks lousy except if on a 1600x1200 monitor), or centered with a dual letterbox border.
Also, most off the shelf monitors are now wide screen with either 8:5 or 16:9 aspect ratios. I think the 4:3 VGA aspect has come and gone. |
