Hi all,

Following up on my February post about the two-Pico system with the real 6522 bridge—I've continued pushing this project forward and just released v0.96 of what I'm now calling the W25Q64_INTERLOCK project.

That is really cool! Awesome build!

Hi No True Scotsman,

I’ve been reading through a couple of your threads and like the perspective you bring. I saw the portable‑6502 idea and the ESP32 terminal angle, and it reminded me of a project I put on the back burner: a Pico‑based 640×480 color HDMI terminal with 80 columns. Even had small ...

Hi all,

Just a small follow‑up to this thread. Working with the VIA emulation here (and all the experiments with LCDs, SD cards, SPI, etc.) eventually pushed me into building something much larger. I ended up taking everything I learned from the emulator and wiring tests and built a full smart ...

Hi everyone,

I’ve been a member here for a few years now, and I wanted to share a project in hopes of giving something back to the community. This started as a small personal tool and unexpectedly grew into something much larger. I’ve now released it publicly in case it’s useful to others.

Hi,

I'm trying noneya's VIA emulator in PICO-6502. Here's knight-rider code in a1basic.
Note I moved the base address of 6522 to $B000.

10 POKE -20478,255
20 K = 1
30 FOR I=0 TO 7
40 POKE -20479,K
45 GOSUB 500
50 K=K*2
60 NEXT I
70 K=128
80 FOR I=0 TO 7
90 POKE -20479,K
95 GOSUB 500 ...

Hi, noneya

Your project sounds very interesting. I'm looking forward to see it.

Actually, I didn't write any 6502 code for pico-6502-apple1, just wrote a1 PIA emulator in C code.
The binary in 8KBasic_Monitor.h came from RC6502 replica 1 project.

jfoucher > I forked the repo and will sync my changes tomorrow. Let me know if you would be interested in pull request back to your repo ?

I'm curious if Fake6502 is open source, as well as the work you've done with 6502emu.c, etc?

Thanks

Sorry for not responding earlier. As far as I can tell ...

Hi kuwatay - That is awesome and thanks for sharing!

You also beat me to it ! :-) I am putting the finishing touches on one which will have Taliforth 2, Krusader, Wozmon, and EHBasic. EHBasic will load from an sd card to RAM at $5000. This will actually (purposely) be 2 PICO's, one serving as the ...

There is also Krusader and the A1 Assembler, those are the two I use on my hombrew's.

I like both of these. Both support lables.

I modified the A1 assembler a to add load and save commands, which work with my SD card solution. If you like it there is a nice sb assembler which is it's desktop ...

Yes, thank you !

* This post has been updated after further work on this code*

External input/output is now working. To accomplish this, I heavily modified the read6502 routine within 6502emu.c. It may ultimately end up that this was not necessary, I still ponder if there was some small issue causing external input ...

I was able to get output to work fine, it was just that in main, line was in place, while needing to be replaced by its comment Looking now to get external input to work.

Thanks

I recently received a few raspberry pi picos!
My original idea was to use one of them as a VGA output for my 6502 computer , but that did not really work out.

So I took a different tack about what to do with them and decided to run a 6502 emulator. The I/O is very simple and goes through the Pico ...

Hi Dietrich,

Nice, you've got allot of interesting things to check out on your Github!

I did find and run your editor just earlier, in fact your's was the first editor that I got to work.

While I was trying to implement the one from the 79' manual, I had missed the (line) with the following ...
