Sorry about the title on the previous post. Darn spell checker gets a little
carried away sometimes. How it got Inferno from Infotron is something only
Gates and Co. can answer.

Subject: Inferno IF/65 Development System II for 65XX microprocessors
Hello group,
Here I am again, looking for information on something that, more than
likely, not a single person on this list will have any information
whatsoever. At least this item isn't on eBay. The last thing on eBay that
I asked for information on somehow managed to attract all sorts of interest
and bids after I posted questions looking for some information on it (I had
the opening and only bid for quite some time). My toes still hurt from that
one. I should have known, since it had the letters D-E-C on it. BTW, who
is pdp.org?
OK, now that has been expressed, what I have here is an Infotron IF/65
Development System II. It appears to connect via RS-232 to a dumb terminal
for its output of such things as address and data, and perhaps input of some
parameters such as uP clock rate; baud rate is selectable from a thumbwheel.
This system also appears to have the capability of single stepping the
program contained in the device in the ZIF. It has a 28 pin ZIF socket for
the targets EPROM/PROM/ROM. There is a standard ribbon cable that connects
to a pod, and the pod has a braided ribbon cable that terminates at a 40 pin
dip header, most likely to attach to the target in place of the uP. Trap
conditions are selectable via four 0 to F thumbwheels, and conditions to be
triggered on can be selected as memory data read, memory data written,
and/or op-code. Any information would be greatly appreciated, a source of a
manual or instructions for use would be fantastic. For those in this group
that maybe can help and would like a photo sent as an email attachment,
please post your request to the group, on thread, and I'll email the photo
off-list. Or just go to
http://www.wpic.com/whdawson/Pics/infotron.gif
Which brings up another point. If all this verbiage is being collected for
posterity, and a picture is worth a thousand words, would it be a good idea
to have a photo archive indexed by thread also? I do realize that
uncompressed pictures can take up a lot of disk space, and a size limit
would have to be implemented. However, as I see the confusion and
misunderstanding some of the time among ourselves, a picture would aid
tremendously in avoiding this situation. Just imagine how much it will help
the denizens of the future in coping with the many objects discussed herein.
I understand there are many of you who are limited to text reception and
transmittal, but what about the rest of us? With all the recent discussion
about the time it takes to read and reply to this email if it is not
properly formatted, etc. being such an issue when the list came back up
(BTW, thanks Jay), I'm surprised no one brought up all the time it takes to
describe things when a simple picture would suffice.
Thanks,
Bill
