DVK MC1201 (PDP-11 compatible Soviet computer)
Re: DVK MC1201 (PDP-11 compatible Soviet computer)
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.

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
Thanks,

Hi,
Is someone can help me running tetris please ?
i mount drive : tetris.dsk and choose bank1
then i type : B
my1
and nothing happened, what should i do ?
THX for your help.
Re: DVK MC1201 (PDP-11 compatible Soviet computer)
I don't think supplied container initdisk.img has anything in any banks besides bank #0. I'd say, you need to:
- 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)
- Make sure you are using bank #0
- 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
1 Files, 29 Blocks
18 Free blocks

Re: DVK MC1201 (PDP-11 compatible Soviet computer)
Is it running fine? Don't you get INTEGER OVERFLOW when you play Tetris? Which core version are you trying?
Thanks,
Shark
Re: DVK MC1201 (PDP-11 compatible Soviet computer)
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

Have you tried to set "CPU slow:" to "ON"?

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

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,
