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. -----Original Message----- From: Bill Dawson [mailto:whdawson@mlynk.com] Sent: Friday, February 11, 2000 10:16 PM To: Classiccmp@Classiccmp. Org 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 whdawson(a)mlynk.com
