Yes; I know that the "B" in ECB stands for "Bus" already :-)

I found today an old (1982 :-) article in a small german
computer-club-newsletter about the differences in those
incarnations of the ECB as they existed at that time.

The mentiones manufactures were:

Kontron Munic (still in existance); 'inventor' of the Bus
Hofman electronic lab Bad Rappenau
Janich & Klass
eltez-80 "Elektroniklande" Münster

I have to see how to resurrect the 2.5 pages which have become
some sort of yellow already...

Yours, Holger

There were just a few more flaviours...

I think I also have some information about the differences of several
manufacturers versions. If it's of interest to collect as much as
possible, I might look for it.

I still have the documentation for all Janich & Klass boards I used in
the 80s. So if that is needed let me know and I will dig it out.

Yes, thank You!
if some of You find information on:

Kontron Z80 ECB/C8 Rev:5.4, (only 2 IC on board),
Kontron DCT 086 Rev:7, (all IC in socked:=out),
Kontron DPR 087 Rev:V, (board seems complete).

so what You can see from this is:
i do need a lot of info to get those card going again!

But thank You for just digging!...

I'd scan them, BUT they are barely readable:

One day I'll retype the listing.

AFAIK it stands for "Einfach-Computer Baugruppen" (Simple Computer
Modules).

^^^^^^^^^^^^^^^^^^^^^^^^^
I make that ELZET-80 "Elektronikladen".

Further I seem to remember Frank & Britting, Dobert & Bitsch,
and what was the name (single IIRC), of the supposed "Mercedes" of ECB
based computers? They separated everything, like memory on an extra
ECB board, terminal i/o card, etc. And who made the extremely fast
"Video-5" board?

Thanks for take Your time,
but those CPU-card are bigger than my.
(there could be good info for my card later in there)

Thanks and have a nice day!

have you Photos of your CPU-Card's?

I have many Boards ECB-BUS and no ECB-BUS.

I assume one reason you have photos of these boards on your Web page,
is to get more information about them. It might helpful to you and to
others, if you include on your web page a list of your boards, and
include whatever information you can read visually from your boards. I
looked at some of your photos, and this is some of what I saw:

ECB board Z80
Z80B, SIO, CIO, 2797 floppy controller chip, ROM, 128K RAM
built in 1984

CCS85 board - Computersystem ??? Weidner 2104????
Z80?, 8255, ROM

"DEMAG" board - DEMAC DII 96121347
8255, many LM339 and 74LS641
I/O card

If you have this text on your Web page, then Google and other Web
search software will find these words. Anyone looking for these boards
will find *you*, they can help you or you can help them.

I'm not familiar with the ECB bus, so it's good to see some discussion
of it.

That is provided much work all Boards with Text too and costs much
Time. I do not have much Time I must also Work.

If questions are there ask me

Computer with Z80 or Z180 on ECB-BUS Board is my Hobby.

Yes, you're absolutely right. The German Wikipedia was wrong too, until
just now, the English one does not have an article yet.

This is the first paragraph of
Johannes Assenbaum, Verbindend, Der ECB-Bus, c't 1985/12, 60--61:

Als 1977 bei Kontron die ersten
ECB, in vollem Wortlaut Einfach-
Europaformat-Computer-
Baugruppen, geschaffen wur
den, ist bestimmt niemandem in
den Sinn gekommen, daß der
ECB-Bus ein paar Jahre später
De-Facto-Standard für modulare
Z80-Systeme sein würde.

They are not readable at all... (dead link) :-(

I already retyped mine, and could include your information.

Sure, You do have a lot of cards!
impressive stuff...

i do have, or could make photos, but have,
at the moment no public place to put the stuff,
and i don't think it could help anybody?

But thanks anyway!

I have retyped the available information, here it is:

If anyone has corrections or additions, please let me know.

> Have you Documentation of the Backplane.

The backplane is simply a completely parallel bus, except for the two
daisy chains. Normally, the power supply tracks are much wider than the
signal tracks, and also connect 1a+c resp. 32a+c.

I have Backplane with two daisy chains and Backplane without two daisy
chains.

Have you more Info for the two daisy chains?

Thanks and have a nice day!

All Z80-peripheral devices have two special pins:

- Interrupt daisy chain IN ("IEI")
- Interrupt daisy chain OUT ("IEO")

The second one is for BUS-Request / Bus-Aknowledge used by DMA

The designer of the ECB-Bus must have been drunk by too much
'Oktoberfest beer', because of the layout of those 2 pairs:

It would have been too simple to put one INput on the same
nmbered Pin Line (a) and the Output on (c) (or vice-verse).

Instead they are on not-adjacent lines:

11a - BUSRQ/ 11C - IEI
31a - BUSAK/ 16C - IEO

Or does someone know the reasoning?
