[Simh] ADC Super Six simulation question

[Howard M. Harte]

Hello Malcolm,

 

I wrote the ADC Super Six simulation for SIMH a while ago (maybe 2007 or
2008.)  I found some of my original files today that I used to create a boot
disk for a Digitex computer that I have with a Super-Six in it.  I built the
CBIOS in SIMH, tested it on SIMH, and then wrote it to a real floppy disk
using ImageDisk.  The real computer actually booted!  Today I uploaded this
stuff to GitHub:

 

https://github.com/hharte/digitex

 

It has been a long time since I worked on this, and I forgot nearly
everything about it by now; however, there are some notes and a SIMH config
file in the GitHub repository.

 

Take care,

Howard

I'm trying to get ADC S6 simulation running in the altairz80.exe simulator -
so far without success.

 

Here are the SIMH commands I've been trying:

 

SET ADCS6 ENABLED

SET CPU Z80

ATTACH ADCS60 AD-MS-P1.IMD     [this is the name of a known good IMD image
copied from real 8" floppy]

BOOT ADCS60

 

The BOOT command returns the following message, but then hangs indefinitely:

 

Booting ADCS6 Controller

 

My questions are:

 

1.       Any suggestions as to why this is hanging indefinitely - am I
missing some critical steps?

2.       Do I need to load an image of the S6's on-board EPROM somewhere?

3.       Can other floppy image formats (such as DMK) be used with the
simulator?

 

If anyone has a working SIMH script and IMD boot disk for the S6, I'd
appreciate a copy.

 

Thanks in advance, Malcolm.
