If your assembler's .lst (list) file output includes an alphabetized list of all the labels and how many times each label is referenced, you can see which ones never got used, and especially if they're not just local branch labels, remove (or comment-out) the particular routines.

I use the MultiEdit professional programmers' text editor, the last DOS version, with an absolutely astounding long, long list of really nice features and a manual that's a inch thick. Today all versions are for Windows only, unfortunately. Giving it stiff competition today is UltraEdit which is als...

I describe a couple of conditional-assembly situations where no number of passes will ever end the phase errors, or where dozens of passes may be required (which may be ok), at http://forum.6502.org/viewtopic.php?p=45897#p45897 . Those are unusual though. A solution for the first one might be to hav...

Sadly Bombjack.org is down

I suppose you could turn the monitor brightness down if you think it's too bright. I do like that it's much, much easier to read now. The way it was before, I kind of had to highlight the quoted sections to be able to read them at all, with that dark grey against dark blue, or whatever it was.

Hi, very interesting. Really useful post. Thank you, I'm new This is a very typical first post for a spammer, and a near guarantee that you are one! On the forums I moderate, when I see this I do a quick search and find the person has left quite a trail of spam, and I ban them and kick them out imm...

I have designed switching supplies (SMPSs) into several of our aircraft products where they had to be really quiet to avoid getting switching noise into the radios and into the entertainment electronics. Getting such good performance out of them is beyond the capabilities of mere electronics hobbyis...

I would think that whatever you're trying to do would be better done with macros.

A 65816 has 22k transistors? I thought the 6502 had 3500 transistors. If that's correct then how did it jump so much in transistor count? According to https://en.wikipedia.org/wiki/Transistor_count, WDC's 65c02 (ie, CMOS) has 11,500 transistors, and the 65816 does have 22,000. My guess is that the ...

These are discussed in my treatise on 6502 stacks (plural, not just the page-1 hardware stack), particularly section 6 on passing parameters and section 14 on local variables and environments. Edit: It shows how to do what rainwarrior mentions below in section 7 , on inlining data. It's mostly about...

I'm paying $60/year at Digital Ocean ($5 a month price for basic hosting service): https://www.digitalocean.com/pricing/ . Running our son's server (where my site was originally hosted) costs three times that much just for electricity (although our residential electric rates here is SoCal are high, ...

Near where I worked around 1990 there was a truck-repair place. To save the labor cost, truckers would often buy parts there and do their own repairs out on the street, parked nearby. I used to go out for a walk at lunch time, and sometimes got to talk to them. One time there was a flatbed with a co...

The oldest playable pipe organ was made in the 11th century. The keyboard is the same as our modern keyboard. Yeah, but back then another person had to pump the air into the organ (or the player had to do it with his feet), today a small electric motor does this job. Organists' feet were busy with ...

Bikes. Sure, they got disk brakes and other new fancy stuff, but often this is optional. You can use a 50-year old bike and, assuming you replaced the parts that needed replacement, it'll still work great today, and - as opposed to 50-year old car - nobody will immediately notice how old the bike i...

No; the point would have been to make a machine (let's call it an Apple IIx for the sake of discussion) which can, while multitasking, run 32-bit IIx programs,at the same time with II GS programs that have not been recompiled for the new processor, at the same time with 8-bit Apple II programs whic...
