Many years ago I maintained a system that had a PDP-8i. I remember toggling in the RIM loader. One thing I recall from the programmers reference was they actually recommended using self modifying code! 😮 That was normally considered taboo! Back in those days I also worked on some PDP-11s & VAX 11/780s, Data General Nova & Eclipse, Collins 8500 and some Prime computers. My own computer was an IMSAI 8080, which also had a front panel.

As mentioned there are trade-offs one has to make. When the set of flags was mentioned I immediately recognized there was no mention of a negative flag. It would have been possible to use the middle four bits of opcode 0 to have several pages of 16 instructions so some useful ones could be added but, as was pointed out, it would add to the complexity of the CPU design and cost.

Nice video, one comment - the code in the example at 42 minutes is in error. Due to the lack of ret after the mov rax, 0x02 it will run onto the mov rax, 0x01. I e. No matter if the result of the comparison is true or false you will still end up with 0x01 in rax.

I missed the name of the antenna design software. I have used Xnec2c in Linux quite a bit and 4nec2 seems to more or less work in Wine and probably fine in Windows. As far as I know they are free as in they don't cost money or expire. I don't know if they are better or worse than other options, but it is kind of funny using a GUI to basically fill in virtual punchcards.

26:20 I remember one of the Apple II machines had this "clever" trick with a Green/Magenta screen, where is could either drive both the green and the magenta subpixels, *or* the green from one and the magenta from the adjacent pixel! They used this to double the solubility (not the resolution) of the screen. Like a predecessor to modern anti-aliasing. Might it be that the Mega II has a similar trick, where it "knows" the arrangement of the subpixels and shifts them over per subpixel instead of per pixel to add to the apparent resolution? You could try outputting to a genuine IIe display to see if it "works".
@bald_engineer29 күн бұрын
The IIGS's composite circuit, which I used for the early stages of the project, doesn't output the same composite signal as the IIe. Mega's 4-bit RGB signals and SERVID (the luma/chroma data for each line) output the same data. The 4-bit RGB signals are a de-muxed copy of SERVID. Unfortuantely, SERVID does not behave exactly like the SERVID on the II+/IIe.
