I've been using Teraterm (http://ttssh2.osdn.jp/) for quite some time now and am generally pleased with it.

jmp(FFFA), BDD's comment about microcontroller speed was with reference to using it as glue logic and more-sophisticated logic (an MMU in this case) to support a 6502/816. In a recent topic , I figured a 25MIPS PIC (100MHz in that case) was marginally fast enough to substitute for glue logic for a ...

However, commentary by others has suggested to me that the PIC's throughput is not all that great relative to clock speed.

I have it on good authority that a PIC32MZ clocked at 14 MHz will run circles around a 65816 running at 14 MHz.

But if you want some hard numbers:

ARM Cortex M4: 1.25 MIPS ...

The RPi has very little general-purpose I/O; and with the things it does have, you won't have any hope of every understanding every bit of all the software layers right down to the metal. Where will the next generation of engineers come from? They're all conditioned to have "all this stuff already ...

So basically you (or David Cramer) is saying that all of the many advances in processor architecture that have occurred for the past 30-40 years are irrelevant, at least for the "hundreds of different products being made today."

Excuse me if I take that claim with a grain of salt and require ...

Anyone know of a Verilog 6551 core or a Verilog project with a Verilog 6551 implemented into the project?
Not sure if it's of interest, but there was a 6850 core included as part of a 6809 project here: http://opencores.org/project,system09 The 6850 has similar capabilities and a similar bus ...

Anyone who knows where I can get/buy these? The original manufacturer no longer makes them. They can, for example, be used to make the high-speed RAMS breadboard friendly.
Have you considered making a run of the PC boards yourself? If you've done PC boards before, it shouldn't take you more than a ...

That is an impressive bit of 6502 code! It would be interesting to see how many bytes an x86 "master" could translate it into.
Out of curiousity, I did a little searching and found this: http://www.boo.net/~jasonp/bf3pi.zip which does it in 40% the size of the 6502 code (52 bytes)!

Back on topic ...

In the hands of a master like dclxvi, the NMOS 6502 can do something similar in about 130 bytes , but I agree that 8086 code is impressively dense. [double entendre, anyone? :wink: ]

That's an important point. 65xx programs are not huge like what you see in the x86 arena. I've written some really big 65xx programs over the years, but only once or twice exceeded 16KB code size.
If you're programming the x86 in 16-bit real mode, the code density is very high -- much more so than ...

My project (PCB stage) includes a 6809 and a couple of Altera Flex10K to implement a bus stealing DMA controller and a simple 4K/16 page MMU, as well as other functions. I am consciously limiting myself to through-hole, 5V parts.
I'm consciously limiting myself to parts available in DIP format, or ...

Also possible, I would think, would be synthesizing the function of the '612 in a 22V10 GAL.
Unless you know of some tricks I don't know of, I don't see how this would be possible. First of all, the '612 is a 40-pin device and the 22V10 is a 24-pin PDIP. Second of all, as far as I know, the 22V10 ...

Still, the point being that you could use the FPGA to implement an MMU and, as extra credit, custom instructions to manage it (as opposed to having a memory mapped interface). All with a stock 65c02.
If you're going to the trouble of using an FPGA, you may as well do everything on it as Rob ...

The '612 can be found on Ebay in both LS and HCT. Currently the '610 can also be had in LS.
Thanks! Just found a couple of them there. Performance is disappointing (75 nS worst case access time) but it should be adequate for speeds up to 4-5 MHz assuming one uses relatively fast memory with it ...

There's a second source for MC6829 compatible IC's that I found on Ebay one day. It's under a completely different part number which I can't recall at the moment but it does exist. The 6829's only a 1MHz part though.
If you think of the part number, let me know. Always nice to have in my growing ...
