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,

thanks a lot, I'll look forward to getting it in due course :)

Re: Bootstrap and boot blocks

Hi Bill,

That’s neat!

How is it done?
Are there any changes in MEMU?
How did you get from Alan’s image file to a “special” CF image for MENU, or is it unchanged?

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...

Re: Bootstrap and boot blocks

@Dave: Mem and Swap blocks are 1Kbyte Thanks Alan, I seem to be missing some memory.

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

Re: Bootstrap and boot blocks

Anyway back on topic Alan I'm pretty taken with the concept so far and wonder whether it deserves it's own section on the forum? That probably depends on how willing you are to keep contributing going forward? I guess that implementing FUZIX on many platforms might be more of interest to you than s...
