Mattis,

 

These are VDU472C which were produced with both Nokia and ICL badges. They are 
very much a straightforward IBM3179 clone and have normal IBM coax ports on the 
back.

They have 122-key PC style keyboards with a large plug. Not sure if they are AT 
or XT style. A parallel printer port. Inside there is a M68000P12 CPU.

So an “embedded system” with no floppies. I have it plugged into am IBM 3174 
screen controller and can connect out to 

 

I know Matt Burke (9track.net) has plugged his SDLC 3174 controller into a 
CISCO router and used CISCO SDLC encapsulation to pass data to a modified 
Hercules.

This works for MVS but not MTS or VM.

Hi!

 

What kind of Alfaskop terminal do you have?

 

Incidentally, me and a friend has been working quite a lot with Alfaskop 
terminals lately. I have been refurbishing a complete Alfaskop S41 terminal 
cluster with terminal , floppy unit and terminal controller. In the process I 
have dumped all PROMs, PALs and FPLAs so that my friend could create an 
emulation of the system in MAME.

 

A bit of the project is described here:

and here:

This short clip show when we just recently managed to boot the terminal and the 
communication processor.

Aside from getting emulation of the cluster we are working on building a 
gateway to bridge IBM BSC to TN3270 so that the system could be used with 
Hercules. Then also we are looking into creating hardware so that the emulated 
communication processor could talk over the proprietary interface used by the 
system with a real Alfaskop terminal. 

 

So the answer to your question is that to get an Alfaskop running you need the 
communcation processor and a floppy drive. There are some variants that are 
more self contained. The older System S37 had a model which included the 
emulation software in ROM. But I doubt that one had a setup menu. It had very 
simple 8 bit TTL CPU.

 

Then the system 41 could run in standalone mode. But it still required a floppy 
drive to load the software from. 

 

I don't know much about the later models, but my understanding is that those 
also booted from the communication processor, the 9101.

Folks,



Can any one remember how to get an AlfaSkop terminal into local setup mode>
