MCMs Final Hi-Res Astrocade - Report 5

[@ballyalley]

This is a great video. Thanks for creating it and showing us your personal Astrocade that you have modified to use the custom chips' commercial ("hi-res") mode. I agree with you, viewing these classic systems always does look much better on a real CRT screen versus a modern flatscreen TV because the picture looks, as you said, "emulated."

Thanks for the positive feedback. When I ran the hi-res screen SRAM test @11:48 in the video, I stated "that was 4 passes right there". That was an erroneous statement. What you saw was only 1 pass of tests for the hi-res screen RAM. In this video, you can see an out of focus dual 7-segment display just below the TV screen. This display is part of the BalcheckHR diagnostics/demos board. When the hi-res screen SRAM test is executed, the dual display initializes to 00 and counts up by 1 each time a test pass is completed not finding any data errors. When I made the erroneous statement, the dual display was at 01 indicating only 1 pass of tests was executed on the 16KB hi-res screen RAM. Oops! So, 4 test passes would have taken 4 times longer to complete. MCM Design Dec 2022
