КР1807ВМ1

[Serge V.]

Купил пяток КР1807ВМ1 - точный аналог T-11. Это такая однокристальная
PDP-11. Описание есть в сети: http://www.bitsavers.org/pdf/dec/pdp11/T11_UsersMan.pdf

Теперь можно сварганить одноплатную PDP-шку, способную нести Unix.
Схемы имеются:

Есть энтузиасты?

У него есть и обычные PDP-шные порты, и специальные для эмуляции
консоли. Если бы вместо самопальной БК сделали бы Терак, было бы
гораздо круче: http://bitsavers.org/pdf/terak/

hello Serge and Leo ,yes it would be a nice idea .
t11 processors can be found easily on rqdx3 floppy and hd controllers ,often
on ebay a a reasonable price because nobody use those very fragile and very
old hard disks.but where do you find КР1807ВМ1?
another question what software did you use to produce the .pcb,and .sch
files?easypcb (what version) ,eagle?I use eagle 4.16r2 and could not open
them.
best regards to all ?

Hi, nierveze!

.pcb and .sch is extention P-CAD 2002.

hi Dimitry
thanks very much ,
I downloaded the free viewer
http://www.pcad.com/resources/downloads/viewer_downloads.aspx
it works.

hello ,I have just loked at the schematic of your idea ,and at the data
sheet of the DEC T11 ,the two processors seem nearly identical from the pin
point of wiew,is there a data sheet of the
КР1807ВМ1 somewhere to know more precisely ,trigger.ru seems to
list a КР1807ВМ1 at 62 rub that is 1€5,is it the good circuit?best regards
to all

Hi Alain,

> old hard disks.but where do you find КР1807ВМ1?

Occationally, I found them at Platan:
http://www.platan.ru/cgi-bin/qwery.pl/id=60599&group=170

There are still 4 units in stock. I do not know if they deliver
abroad.
If they do not, I can send you a couple of units. :)

> another question what software did you use to produce the .pcb,and .sch

I prepared a PDF version of schematics and PCB:
http://bk0010.googlegroups.com/web/1807vm1-board-sch.pdf
http://bk0010.googlegroups.com/web/1807vm1-board-pcb.pdf

Is it possible to convert SCH from P-CAD to Eagle?

Лениво видеодисплей городить. Достаточно UART и пары CF-карточек в
качестве дисков.

> is there a data sheet of the КР1807ВМ1 somewhere to know more precisely

Unfortunately, I cannot find any documentation for 1807ВМ1.
People says that it has no diffrences from original T-11.

> trigger.ru seems to list a КР1807ВМ1 at 62 rub that is 1 EURO 5,is it the good circuit?

Price is good, the only problem would be with delivery.

hello Serge and everyone on the group,I have asked Platan and wait for
their answer.
Thanks very much for your proposal.
Thanks also for the pdf version of your system.Good ideas.
I have tried to use your .pcb and .sch it with eagle ,without success.
I have found this that that is nearly in the same direction and can be of
interrest:
http://www.npofizika.ru/pdf/Bis123min.pdf
and
http://www.npofizika.ru/microcircuits/1582-0123.htm
this schematic shows a simple circuit
with a 1806bm2 +16 of ram and 16k of rom and a circuit that seems to be a
dl11+rtc compatible thing .I did not understand everything in the data
sheet...you will understand :-))) .I do not know if they have
resellers.Please look at their site to give more informations to non russian
speaking people like me ,I am not the only one.It is really interresting
,because with this processor it is easier to implement the qbus than with
the t11.With this it would be easy to use qbus interfaces ,I am particularly
thinking of rqdx3,with rx50 or rx33.Also it is a 'must' to use a dl11 (or
dlv11,or something compatible like this circuit ,or the dlart made by dec
,but impossible to find ,without it is impossible to run rt11 witout
modification, I do not know about unix).
Good bye to all ,good night.alain

hello everyone
I have found again this site:
http://www.cplusplus.boom.ru/
Andrew has made a new version of his emulator that works very well.
And he has put lots of files on his site.I have tested this and made
audio tapes on a win98 pc with his converter ,included in the emulator,
and the 'magnetophone' of win95,connecting it to a real magnetophone
using the sound card.I tested lots of programs both
on the emulator and on a real bk 0010-01.
All those that work very well: micro_8.bin,
disasm.bin,odt2.bin,dump.bin,ag.bin,
basic_02.bin,basic_v.bin,basic-dvk.bin,
forth02.bin,and mirage.bin.
It may be useful.
best regards to all
alain nierveze
ps:I have written to resellers in russia :platan and trigger a week ago ,
no answer:-(((
I'll try to write to angstrom and npophysica ,may be they would accept to
sell their processors....

hello everyone ,I found this:
http://www.torrentportal.com/torrents-details.php?id=1000718&filelist=1
look here
[VARIOUS] Elektronika BK-0010 (1984).zip 16.69 KB
/[VARIOUS] Elektronika BK-0010_01 roms.zip 23.28 KB
/[VARIOUS] Elektronika BK-0011M roms.zip 61.14 KB
/[VARIOUS] Elektronika BK-0011M [merged].zip 31.94 KB
it is the roms of the bk,unfortunately
it is in a p2p site,I cannot use this technology
because I have only low quality connection,
is it possible someone dowload those files and put them on the group,they
would be useful.
thanks very much

Maybe http://www.emuverse.ru/downloads/computers/BK/firmware/ can help
you?

[nierveze]

hello ,thanks very much ,a very useful site ,I did not know,also there is
lots of documentation about others machines often for sale on ebay,I think
i'll spend money :-))) ,thanks again

I've downloaded this torrent, it has a separated variant for 11M. I
don't know if it may be useful but I've saved it at Emuverse.ru too.
