Not an expert here, but if I understand it correctly it should work provided that it supports the implemented devices and you manage to add image to the appropriate slot on the SD card (using sd-store). However, some of those downloads are already included in the disks image. The parent project has detailed description of all devices/drivers and included disk images, in Russian.

Here is a snippet from that doc (from section 10.1):

DM0 RT-11 V5.5 full distro
DM1 XXDP V2.5
DM2 RSX-11M V4.8 full distro
DM3 RSTS/E V10.1
DB0 RSX-11M-PLUS V4.6 full distro
DX0 XXDP with base suite of tests PDP11/70DX1 RT-11 V5.04 minimal
MY0 RT-11 V5.01 with games for ДВК
DK0 RT-11 V5.04
DK1 ФОДОС-ТМОС with test suite
DK2 RAFOS+ v2.1
DW0 RT-11 V5.04 D full distro

As author has warned us, the core is unstable. For me some images boot in the MC1202 core, and some images boot only in pdp2011 core.

Just want to say a big thank you for this core. I would love to see RSTS/e work. That would be amazing. I've compiled up a version of VTWrap for the HPS that isn't a static binary and attached it here. You can get the source tarball by clicking earlier in time once you have clicked the link for the tarball.

Code: Select all

$ docker run -it --rm -v $PWD:$PWD -w $PWD --platform linux/arm buildpack-deps:sid bash
$ gcc -g -O2 -o vtwrap *.c -lutil

This is my alpha version MiSTer port DVK core.

You can play original Tetris by Alexey Pajitnov!

Hi,

Thanks a lot for this core. It's awesome.

I'm trying last version (pdp2011 256kb BRAM), and I can't mount MY0 disk (selecting bank 1). With version MC1201_20211030 works (doing B and MY0 and bank 1).

Playing Tetris, from my point of view it's not so accurate, because although I selected set "CPU slow:" to "ON", Tetris game runs fast. Could you improve this point?

Thanks and kind regards,
Shark

Another issue... Release MC1201_20211030 and "CPU slow:" set to "ON".

INTEGER OVERFLOW

I don't think supplied container initdisk.img has anything in any banks besides bank #0. I'd say, you need to:

  1. Mount the initdisk.img container (contrary to what OSD menu says, it's not a disk image, it's a container for all disk data)
  2. Make sure you are using bank #0
  3. Boot from MY0 (B MY0) and just start tetris by simply typing TETRIS

That's how the boot sequence may look like (using serial console as described above):

Code: Select all

 152462
@B
$MY0

RT-11SJ  V05.01  

?MON-F-Trap to 10 002212

.DIR TETRIS.SAV
 
TETRIS.SAV    29  04-Dec-86

Is it running fine? Don't you get INTEGER OVERFLOW when you play Tetris? Which core version are you trying?

Thanks,

No integer Overflow, i used last MC1201 core (MC1201_20211030.rbf). A little fast but it's playable, now we wish an elektronika 60 core :mrgreen:

Hello,
just for curiosity and if i can ask, why this core is not present on https://github.com/MiSTer-devel section?

It's not an official core?

Thank you

This core is under development and requires some bug fixes.

Would the simh source code be any help? I have a PDP-11 running UNIX 7 under simh with these instructions.

Yes, LSX works!

Hi,

Which command I need to load LSX?

I'm trying (loading dvk.dsk image first) with:

Code: Select all

@B
$Y0

But nothing happens.

Thanks and best regards,

Hi there, thanks for this precious core! The speed of Tetris is still not the original one, too, is too fast, is it possible to slow down it more?

Thanks!

Hi @xolod79,

Sorry to bother you about this topic, again!!

Could you please share your code with last commit working at 25MHz instead 100MHz?

I want to compare it with the current code.

Thanks and kind regards,
Shark
