hello thanks for your precisions,I am also doing the
same
a few ideas:for the dc inverter what not use icl7660 ,they can give
you -12v,
you can get free samples from Maxim,just register on their site,I
frequently use those circuits for gaasfet lnas (I am a ham also)
Ok, have som 7660 already, but I have to investigate first if they can give
the required current. http://katalogy.ic.cz/MHB1012.html means that I need
14mA for one IC, want to use 2 of them.
for odt the problem is that those processors do not
have odt in microcrode
(contrary of dec's processors),so we will have to make our own program,I
think of using the console of the 11/34 that is here:
http://www.ak6dn.dyndns.org/PDP-11/M9312/
you will find the source,it can be modified to fill the need of the russian
processors ,that need the psw at adress of start+2,and recompiled.
but a problem is if we use dec 's program we must comply to dec's standards
that reques that the processor has a dl11 (or dlv11)compatible board.
as console,not only a uart.
Yes know. I (we?) have to build the entire register structure of the DL11.
There is the DEC DC319 (and an russian equivalent) what should do most of
that already, but currently I have no source for that parts.
Is the soviet serie there are circuits that make this
they are the
KR1801VM1-35 and the KR1801VM1-65
you can find examples of its use here:

file
MicroEVM_Book_2.djvu
can you say me where you found the file that you use for your eproms?what
computer does it come from:bk,dvk,uknc??
Don't know where I found it, but this rom resides on the DBK-2 board.
(MC1201.02).
and where are you,maybe we are not too far??
best regards
good luck alain nierveze
