Update and Pictures: It's been a hell of a day! HP 9845/2x i8008/Sage II/2x Grid/TI Silent 700/Alpha Micro

by rigdonj＠cfl.rr.com

I finally had a chance to look at some of the stuff today. I was wrong about the i8008 comnputers. They each have SIXTEEN 1101 RAMs on them and eight 1702 EPROMs. One of the machines has some non-Intel brand 1101 memories that are dated 7114!!!! (See the yellow arrow at <http://www.classiccmp.org/hp/i8008-1/board.jpg> ). I haven't had a chance to look them up yet but those two white ceramic parts are marked uA3656 or something like that. Anyway the red arrow is pointing to the i8008 CPU. The yellow arrow is pointing to the column with the 1101 RAMs and the blue arrow is pointing to the column of 1702 EPROMs. More pictures of this machine at <http://www.classiccmp.org/hp/i8008-1> and pitures of the second machine at <http://www.classiccmp.org/hp/i8008-2>. The circuit board appears to be the same in both machines despite the very different cases. I didn't get a chance to get pictures of the TI Silent 700 yet but I did open it up and check it out. It's a model 733KSR and IT'S SWEET! It's mounted in the transit case with spring loaded clips and it's in excellant condition and still has the interface cable attached. It also works perfectly :-) According to the labels on the case, it is a part of the same system(s) as the i8008 computers. The Visual terminal also works perfectly :-) I checked the HP 9845B and it's absolutely dead. The fan doesn't even run. However the fault should be easy enough to locate. It's odd though, their is no sticker listing the options and it has a hand written serial number on the SN label. I didn't get to the Sage or the other stuff yet. I HOPE to do that tomorrow. Joe

There is no format which will withstand eternity, so as >long as it can be used NOW and for the foreseeable future it can be >converted later. Hi Brian Even the choice of using ASCII is in question. With more and more things being used world wide, I expect to see information stored in a meta translatable language. This would be something that could be entered in any language and then print out in any other. It would not just be a word translator but also include phases and even slang. I see ASCII as having a limited lifetime right now. Still, for the archives, one needs to keep things as simple as one can and still try to include enough information ( not encrypted ) to recreate the original. It is a task that Sellam has taken. He has made a great start on it. Personal archives are a different thing. I zip stuff myself. Dwight

what's an 11/75?

by jwest＠classiccmp.org

I've been offered two 11/75's. I can't seem to find information on them. Are these Qbus machines, micro11 stuff? Or are they the bigger unibus stuff. Typically deskside towers or rackmount boxes? They are model # 173QA-B2 I've googled and can't find a picture either :\ Depending on what else is in the load, I may take it. If nothing piques my interest I'll pass it on to the list. Jay

I have plenty of DSDD 3.5"floppies, too. But you can't. To use 3.5" drives with turbrom you also need the advent personality card. I had to make mine.

Disk archival techniques

by aek＠bitsavers.org

but a disk format repository solves alot of the tedium. -- does anyone have copies of the media related ANSI and ISO standards that are no longer available? There were standards back through seven track tape which are 'depreciated' guess this is sort of related to the 'dead media project' has anything more happened with the revival of that?

Magnetic tape archiving (was Disk archival techniques)

by aek＠bitsavers.org

Tapes are an issue since they're really not a stream of bytes -- there are tape marks and gaps. The simh virtual tape format seems to be fairly complete in that respect -- The big thing missing from the '.tap' format is it assumes all the blocks are good. There is no way to describe a partially read block, or to encode any of the CRC or LRC check data that was in the tape block on the physical medium.

HP 9000/T520 Systems available in St. Louis - Borderline Vintage but w/14 Processors!

by nick＠computer-history.org

If anyone is interested in newer HP equipment I know of two HP 9000/T520 systems available free for pickup in St. Louis. Currently all 14 processors are in one cabinet, the other is empty. I do not believe there are any other peripherals included. I will be arranging the pickup for the owner of the systems so please contact me off-line if you are interested. Thanks, Nick
