Hi Dwight
The machine is in fact equipped with three connectors, a DB25 for RS-232
communication, a DB9 male for the keyboard and a third connector,
another DB9, female this time, not sure but I think it was to connect a
card reader.
Do you think the serial I/O channel B can share its resour
By the way, how is the terminal and keyboard connected to the computer?
Is it by RS232?
If so, it might be through SIO B. If this is the case, it might be the problem.
Also, the RAM failure may be the issue as well. You have something that is
intermittent there. Bad RAM can cause programs to mi
Hi all --
Got an Interdata Model 70 here (well, the parts to build one, anyway)
missing the front panel key. Anyone (a) got a few spares lying around
or (b) have key codes for this thing?
Thanks,
Josh
I wonder if anyone knows where the actual content of these tapes are
located?
I have a Digital Pathways TCU 50-D card which requires a couple of
routines, and figured it was worth asking while searching.

Since you know the pinout of the SIO chip, you might first look to see if where
the rx and tx pins go. This may require some hunting with an ohm meter. I'd
suspect they go to a RS232 level shifter.
You may also have to write some code to run the serial chip and any possible
external loopback. A

36 years is not accurate. Nor is "today".
38 and a half years.

As described in the topic, just after the Power On, the machine runs a
self-test which is called "POC TEST" on the UTS range of Sperry Univac.
During this test, the machine checks the status of the RAM, the ROMs,
the Counter Timer, and the various communication i

I don't have the stuff to do the disk recovery, but two years ago I got a

He had already done a lot of work recovering data and (IIRC) had a software

You can not fix anything without knowing what it is suppose to do. Chuck's idea
is sound. You will not likely get much with the logic analyzer unless the
processor is actually running some code.
It doesn't sound like it is. You need to check that it is.

Hi Chuck,
Yes I understand well. But the fact that the machines Z80 based were all
equipped with this famous serial I/O channel A and B, I therefore
thought that the principle of verification of these channels would
probably be the same on this type of architecture (Z80+PIO+CTC+SIO).

I felt like Cardiff also had a resemblance to Tandy/Radio Shack as well,
since they were in the electronics business before getting into computers.

Hi guys!
Nobody here has any information to help me to solve my problem?
Do you think I should talk about this breakdown on another forum? If
yes, have you an address to recommend me?
