My experience with WinCupl is that it doesn't like spaces in file paths or names.
My advice:
Make sure the path to your WinCupl program does not contain spaces
Make sure the path to your WinCupl project does not contain spaces
Make sure the name of your WinCupl project does not contain spaces
Make ...

I think I for one would like to see more of the actual equates for your variables, etc. (what memory locations are used, i.e., page zero or other RAM). Good point. I'll try to remember to include my equates in the future. The memory usage is still in flux. I need to decide things like "Do I want to ...

I have been working on my BIOS a bit, and have the basics for writing to and reading from the SC28L92 DUART. The DUART is configured with 16-byte FIFOs and to interrupt only when the transmitter FIFO is empty and the receiver FIFO is full. I am currently using 128-byte transmit and receive queues ...

So cool! Thanks for sharing! After reading the description I watched again to see the ABS in action.

I just spent 45 minutes watching drogon make hot cross buns and soda bread. Now I'm hungry!
It's nice to be able to put a face with a user and see them doing something else they enjoy.

Thanks to everyone for their comments. They are very helpful.
I am reading "Starting FORTH", but haven't gotten too far yet.

Complete Forth newbie here. I've recently gotten Tali Forth 2 running on my SBC and would like to set some outputs on my 6522 VIA. It is mapped to addresses $8010..$801F.
What is the typical way to write to and read from memory? Are there existing Forth words, or will I need to write my own?

I may ...

How did you find the NXP to program? Not bad. It is a little more complicated to initialize than a 6551, but it is much more capable and doesn't have the 65C51 TX bug. After initialization, transmitting and receiving data is very straightforward.
BDD has written some documents that explain really ...

Oops! I went out of order.
Here it is running Tali Forth 2.

Nice!
If you post what you tried for FIELD there are a couple of us who might be able to help.

Here it is running Floobydust's C02 BIOS, monitor and EhBASIC.
My next steps will be to write my own BIOS and monitor. After that, I plan to get Forth running.

There were a lot of great suggestions for improvements, and I will definitely keep them in mind for a future revision of my PCB, but I decided to go ahead and order some PCBs based on my original design and layout.
My eyesight isn't what it used to be, and I haven't admitted to myself yet that I ...

because the JEDEC memory pinout is a complete shambles I thought you were referring to something I had done poorly, like the 22V10 pin assignments. I've been bummed all weekend because I felt like a new parent showing off his newborn baby and someone says "that's an ugly baby."

I mean the JEDEC ...

Another option might be to stack them vertically... But you still need to work out the optimal positioning for one, then solder the other(s) on-top but bring out their /CE pins to separate headers on the PCB.

This is a very old technique, but I used it relatively recently for 2 x 32KB chips on my ...

It strikes me that the signals from the 22V10 all go a long way across the board. It might be a better idea to move it nearer to the devices it connects to. Displacing the 7400 and the UART crystal would be a relatively minor and inconsequential sacrifice. Yes, I agree. It should be no problem to ...
