Re: Bootstrap and boot blocks

Hi Alan, thanks a lot, it does not seem to work for me though. Did you upload it to the same link as last time? Can you change the time using the ":" key? That doesn't work on my PC (laptop). The Scroll Lock mode should enable the ":" key, but doesn't work for me. Of course, I could have made a mess...

Re: Bootstrap and boot blocks

Hi Bill,

That’s neat!

How is it done?
Are there any changes in MEMU?

Regards
Dave

Re: MTX 512 (debugging thread)

It might be worth making a quick check of the voltage on the sense lines that I described in the second link. That might or might not show anything, but it is a quick test to do while you are looking at the VRAMs

Re: MTX 512 (debugging thread)

Is the behaviour in the last screen repeatable? i.e., what happened the next time you turned it off/on, was it the same? Different VRAM chips from different manufacturers are OK, provided that the spec (speed is the same). Shorting the VRAM (through a resistor) to ground is a good test, but by no me...

With the 64-512 PROM installed on the memory card and all jumpers set, there s...
