Parallel printer:
A2 - Strobe - 1
A7 - D0 - 2
A6 - D1 - 3
A5 - D2 - 4
A3 - D3 - 5
B3 - D4 - 6
B5 - D5 - 7
B6 - D6 - 8
B7 - D7 - 9
B2 - Ready - Ack
A1,B1 - GND - 18-25 (DB25) / 19-30,33,17,16 (Centronics 36 pin)
-
SERIAL for two Enterprise:
A1 - A1 Reference
B1 - B1 GND
A3 - A4 Status out-Status in
A4 - A3 Status in-Status out
B3 - B4 Data out-Data in
B4 - B3 Data in-Data out
NET for up to 32 Enterprise machines:
B1 on all machines to GND line
A3 and A4 on all machines to STATUS line
B3 and B4 on all machines to DATA line
SERIAL for PC:
A1 reference - GND pin 7 (DB25) / 5 (DB9) Note: this connection shift the Enterprise logical levels to -5V (0) and +7V (1)
A3 Status out - CTS pin 5 (DB25) / 8 (DB9) 1.5K pullup resistor needed to +12V
A4 Status in - DCD, DSR, DTR pins 6, 8, 20 (DB25) / 6, 1, 4 (DB9)
B3 Data out - RxD pin 3 (DB25) / 2 (DB9) 1.5K pullup resistor needed to +12V
B4 Data in - TxD pin 2 (DB25) / 3 (DB9)
The pullup resistors can be connected to DTR pin 20 (DB25) / 4 (DB9) on the PC.

Enterprise for Commodore Serial, using CBM disk drives and printers with CBM MFT program:
CBM 2 (GND) EP NET B1 GND
CBM 3 (ATN) EP Printer B7 Data7
CBM 4 (CLK) EP NET A3,A4 Control Bus
CBM 5 (DATA) EP NET B3,B4 Data Bus
CBM 6 (RESET) EP Printer A2 Strobe

Joystick, simple wiring:
A1 Common pin 8
A4 Right pin 4
A5 Down pin 2
A6 Fire pin 6
B5 Left pin 3
B6 Up pin 1
Note: with this simple connections can't used Auto Fire or other electronics in the joysticks. For using these needed some active components (transistors or ICs) for the conversion.

Final versions here

Wow, great work! Thanks!
Now I found one mistake :-(
This book (on PDF page 84) (http://enterprise.iko.hu/books/TippekEsTrukkokEnterprise.pdf) write wrong printer connection :evil:
Now I checked my printer cable, the right connection at EP B2 to pin 11 (Busy) on the printer.
I'm sorry for made some extra work for you!
-
Great continue!
For the PC connection, see this document (http://enterprise.iko.hu/technical/Enterprise-AppNote-29.pdf), about the resistor placements.

(???some misunderstand with B1)
B1, Enterprise GND must be NOT connected to the PC. Insted the GND the reference used, with this trick shift the Enterprise logical levels to RS232 levels, from 0V (0) and 12V (1) to -5V and 7V. and the pullup resistors make the 12V from the 7V signals.
pin A4 and 20 must be connected?
The official Enterprise document say A4 connected to both 6,8,20 on DB25.
pin 1 and 4 must be connected?
From the previous document converted the DB25 to DB9, A4 to 6, 1, 4.

I made corrections.
All OK?

Thanks, it is fantastic work!
I think all is ok.
Only the Scart cable (http://enterpriseforever.com/hardware/build_a_rgb_scart_cable-t332.0.html;msg27750#msg27750) need some aditional GND connections.
When I put your graphics to my webpage, what I write for? "Graphics by SlashNet" is ok? Or do you want your real name?
-
"Graphics by SlashNet" is ok?
That will be enough. ;-)
UPD: Add SCART (old versions delete)
-
I added your graphics to this page. (http://enterprise.iko.hu/pinouts.htm)

Found more authentic font.
I updated the pictures and make few cosmetic edits.
That's all

Made some changes to SCART connection:
Added info about resistor value: (info (http://enterpriseforever.com/hardware/resistor-values-for-scart-cable/))
And change connection wire from "A7 -> 3" to "A7 -> 6" (info (http://enterpriseforever.com/hardware/resistor-values-for-scart-cable/msg37035/#msg37035))

Thanks! I replaced the image on my page.

Small comment.
I adjusted the picture size to the size of all other. But on the webpage hardcoded dimensions stay old. So image looks little distorted.
Correct dimensions: width="650" height="300"
