This also needs chasing down. ROMWBW does various bits of UART detection but it's not clear that this fails, or why it keeps rebooting and if this is an interrupt related problem.

Workaround: use SIO

I just built the the rc2014 emulator from sources. I invoke the emulator as follows:

./rc2014 -s -r ~/git/rc2014/ROMs/Factory/24886009.BIN -e 1

I then type the following line into BASIC:

10 FOR Y=0 TO 24:FOR X=0 TO 79:PRINT ".";:NEXT:PRINT:NEXT

This should dump 2000 dots to the screen. However, when I RUN the program, nothing appears on the console. I tried it with and without the -f option.

Intermittently, upon typing the ENTER key, a single line of dots will appear. Typing random characters on the keyboard has a similar effect, with the exception of when I mash multiple keys, it appears to break (as though I'd typed CTRL-C) the program instead.

If I happen to have some text in the X11 paste buffer and paste it into the console window, the whole interface just deadlocks after accepting the first character.

I was hoping to use this emulator to develop some Z80 Zed software interactively, but I will absolutely need the ability to paste code into the terminal; likewise, I will absolutely need it to dump entire screens to the console as well. It's not clear to me if I'm doing something wrong, or if there's more debugging of the emulator code that needs to happen. Is there any advice you can offer that will help resolve this issue?

Thanks for your time.

I would like to request Danish keyboard encoding for the NC100 emulator.
As it stands right now, I am unable to use the emulator while my host os is using Danish keyboard layout. I can not even write input , and . (comman and dot)

The 6800 emulation bombs when FLEX tries to print the size of a large disk. This needs tracing to see what flags or similar screwup is involved.

Issue description

Emulation freezes at:

Z80 SBC By Grant Searle

Memory top?

when started with ./rc2014 -a -e 0

and

Press [SPACE] to activate console

when started with ./rc2014 -a -e 4 -p

The Small Computer Monitor seems to work fine with ./rc2014 -a -e 7

Steps to reproduce the issue

Built rc2014 with gcc version 7.4.0 (Ubuntu 7.4.0-1ubuntu1~18.04.1) and running in an Ubuntu 18.04.2 VM with 1 CPU and 1GB RAM in VMware Workstation 12.5.2

rc2014.rom is Factory ROM R0001009.BIN

What's the expected result?

Pressing Enter should start BASIC, or space, x, y should launch CP/M

What's the actual result?

System freezes

Similar results when using ./rc2014 -s -r SIO32K.BIN when the ROM is SIO2/INTSIO.HEX joined to SIO2/BAS32K.HEX and saved to a single .bin file, though in this case BASIC freezes at Z80 SBC By Grant Searle without even asking about Memory Top?

Snake kind of works (when put into an 8k rom file), though the snake only moves when a key is pressed rather than free running.

I copied the working RC2014 emulator/CF image folder structure from my laptop running Linux Mint 19 to the Linux (Ubuntu) Bash shell under Windows 10 on another machine.

The emulator seemed to work as expected (runs Wordstar and various commands I tried), but CTRL-\ does not exit the emulator (does nothing).

The emulator was first downloaded and setup in May this year and uses SCMonitor-v100-R3-RC2014-32k-ROM

Any thoughts, or anything I can do to help debug if needed?

I've noticed that when I try to use arrow keys, the full control sequence is not processed. Similar issues happen when pasting.

When using the sio: ./rc2014 -s -b -r RCZ80_std.rom -i cpm3.cf
If I paste hello I'll see he. If I press up-arrow, I get ^[[ instead of ^[[A.

When using the acia: ./rc2014 -a -b -r RCZ80_std.rom -i cpm3.cf
If I paste hello I'll see o. If I press up-arrow, I get A instead of ^[[A.

Add support to directly access a real physical device a well as the emulated IDE.

If there is an wishlist on new platforms, I'd like to add one platform.
(Sadly, I'm not skilled enough to add it myself)

My suggestion is Microprofessor MPF-1.
https://en.wikipedia.org/wiki/Micro-Professor_MPF-I
I have the actual HW and manuals, I can read out the ROM:s and supply with all the documentation.

One complicating fact is the lack of serial monitor and the UI is a hex keyboard and 7-segment LED's.

Needs debugging to see what is going on

When compiling the module m68kdasm.c gcc (Ubuntu 9.3.0-10ubuntu2) 9.3.0 complains of a array being to small around 334 I increased the size of the static char array and this fixed it.
form this static char str[15]; to static char str[32]; this was just a hack to get it to compile I'm not using the 68K emulation so i'm not sure if this breaks it.
I have not had a deep look at the code to understand the issue.

Hi! I'm attempting to run FUZIX on an emulated RC2014 with a TMS9918A. FUZIX seems to boot correctly, if I disable the TMS9918A and PS/2 emulation then it boots to a login prompt over the SIO. But when I pass the -T and -P options to enable the TMS9918A and PS/2, I just get a blank blue screen.

Here is the exact output:

Disabling only the PS/2 emulation makes it boot to a login prompt over the SIO, yet the TMS9918A output is still blue.

This is using a freshly built disk image that I built locally. I haven't tried your disk image from fuzix.org yet as it was taking a over an hour to download :P

Here is what the blue screen looks like:

I wasn't sure whether to file this issue in this repo or in the main FUZIX repo as I don't know where the error is.

As Idea:
You have the Z80-MBC2 and a 80x86 for RC2014, so how about adding (in a future release)
the V20-MBC? ;)

i would love to have a separate file that handles IO so it would be easier to implement new IO,
so someone could first implement them here and test the principles/Idea before trying to implement them in hardware.

i like the idea how it is done in https://github.com/BleuLlama/z80-machine but this project only includes the z80 processor. But i need Z180.

Thx for your time, have a great day

Hi,

I was writing an emulator for the Uthernet 2 card (based on the W5100 too) and found this code.
There is some overlap, but I need IPRAW and MACRAW while this code uses TCP and UDP.

There is one thing I am really struggling with and it is the handling of Sn_RX_RSR, Sn_RX_RD and RECV.

I have seen your implementation with rx_old. Reading the doc it is not clear how exactly this works in the w5100.

And given that the sending / receiving happens in parallel with the main CPU, how is the real card avoiding race conditions when reading / updating the above registers?

It's now seriously lagging reality

Hi, I've not contributed to someone else's public project before so no idea what the etiquette is. I have code changes to better support my z80retro project on a branch of a local clone of this repo. I don't have permission to push that to this repo to submit a pull request. What do I do?

Add support for routing other serial ports to sockets or physical tty devices

Running Linux squire 5.14.0-4mx-amd64 #1 SMP Debian 5.14.16-1~mx21+1 (2021-11-05) x86_64 GNU/Linux

I booted into forth but can't figure out any way to exit the emulator or reboot it. Doesn't matter which boot option I use (although I'm partial to FORTH). I'm guessing rebooting isn't really a think for RC2014s.

Also - I see the emulator reports a few drives. As I recall Z80 normally talks to devices via ports rather than memory maps. Are there any docs on how to address these drives? I see CamelForth apparently doesn't come with block support. I'm curious to see if I can't add it. Would appreciate any docs on low level system access to the RC2014 with RomWBW. Are CP/M calls available while in the ROM Forth? I've got my RC2014 kit that I'm prepping to build so would love to get comfy on the emulator until that's going.

Thanks and if there's a better place for me to ask such questions please let me know.
