The ILI9341 has an 8-bit interface, and can be placed on the 6502 bus...To get around this problem, you can add an additional 74xx245 that you can then control the OE# pin of.
I did look into the 8-bit interface, but my thoughts were to use this display and the PS/2 keyboard to work as a "serial ...

Re: Supermon 816 and Kowalski Simulator 1.4.0.6
As part of further testing of my simulator on STM32, I compiled from the source code SuperMon 816. The program starts and does not suspend, unfortunately some functions, e.g. A or M, do not work correctly.
So I decided to start the Supermon under the control of the Kowalski simulator and it turns ...

Re: Character Encodings (WAS: Crenshaw - Let's Build a Compi
The VT/ANSI/ECMA48 mess is just that: a big, friggin’, designed-by-committee, implemented-by-a-drunken-monkey mess. When WYSE developed their terminals, starting with the WY50 (and most famously, the WY60), they studiously avoided all that CSI... mumbo-jumbo and adopted a pseudo-binary control ...

A continuation from: Crenshaw - Let's Build a Compiler

Re: Text Editor Shifting Mechanics
The question then is what codes? Go all-out and go for ANSI/vt100 or something else?
I am personally biased against ANSI/VT100/VT52 control sequences...There are many other popular terminal control sequence sets such as ADM3A, Televideo 950, IBM 3101.

Since I started this thread, I did track down a few data books, including the TI yellow book you mention. Mine is from 1984; I'd really like to get the 1989 one (I have a PDF copy of it on my desktop), but it is a bit hard to find it seems. I also got the National / Fairchild one that Garth ...

Re: DOS/65 ROM version 3.02 up and running!
It seems to work well, although I have not yet figured out how the ANSI function keys work. Part of my project for next week, when I should finish my project's VT-100 driver code. Apparently, ANSI function keys != VT-100 function keys.

Re: A VERY simple 6502 programming language
Some key points is that it will only use minimal keywords (IF...THEN, GOTO, PRINT, INPUT, LIST, RUN), all variables are treated as arrays or strings, NO special symbols required, and line numbers for editing. I'm hoping it will fit within a few KB of ROM, and use about 8KB of RAM for variables and ...

Re: 74HCS series?
Unless you need Schmidt trigger inputs I can't see why one would opt for HCS over AHC or HC. Or maybe I'm missing something?
The 74HCS family is targeted at noisy environments, such as machine controllers or automotive ECMs. Take out the Schmitt inputs and you have the 74HC family—essentially the ...

I wonder if it has anything to do with the chip shortage that has even shut down some of the auto industry.

Re: About the humble Floppy Disk…
So, I randomly came back to the subject of EFM encoding and decoding. I've now concluded that this is noticeably easier to do in hardware than in software, as long as you take the correct approach - though finding that approach might be less than obvious. In particular a hardware decoder eliminates ...

That is actually pretty interesting. And it looks like it wouldn't be too hard to make it understand BBC VDU codes instead of minicomputer rubbish. ;-)
