The only thing that is in any way familiar about this is the Cipher name. Cipher Data Products was a supplier of 9-track tape drives for most of the time during which 9-track drives were relevant. For example, I've got an S-100 board set and a controller formatter which comes from Cipher. The board set I have seems to be a Pertec-type interface adapter, though, i.e. it uses the same pair of 50-conductor cables. Is that what you have on this tape drive? Is it a 9-track type?

Basic 4 tape drive?

by foxvideo＠wincom.net

I was just bequeathed a batch of Basic 4 bits, terminals, etc. and the only thing that looks interesting is some sort of tape drive with the following identification: MAI Basic 4 Information Systems Model 4402 and Cypher F880640-90-1025U Can anyone tell me what this thing is?

HP 9144A, other stuff

A former employer tried to get me to use those once, which is how I found this out. After trying one for a while, I declined. Here's why: There are two or three layers of "formatting" on these. The 3M tapes had the lowest layer, the one that must be done at the factory because it requires the full-width head that can write block delimiters. The HP tapes have the next layer as well, the data that is read by the tape drive and which contains usage and block sparing information. If you have an HP3000 w/9144 the VINIT FORMAT command will write this, but in my experiments at the former employer I found it took noticeably longer to format the 3M tapes (perhaps it was testing the tape blocks to figure out which blocks need sparing? I don't know). I didn't think it was worth the couple of bucks we would save per tape for someone to sit on his or her butt waiting for this to happen. But once you do this they do work. And I have no idea how to do this step with a 9000. The third layer? Well, on a 3000 you access the 9144 as though it is a removable-pack disc drive. Fortunately the 3000 has the concept of accessing a disc serially: you use the VINIT SERIAL command to label the "disc" (actually the tape) as a serial volume. I don't think this applies to 9000s but I think for the 9000s you are supposed to pipe tape data through tcio (which buffers the tape drive I/O in a way that reduces wear and tear on the drive and tape). -Frank McConnell

HP 9144A, other stuff

by jeff.kaneko＠juno.com

John: Have you actually tried this? The reason I'm asking is that on the Imation web site, they have a compatibility chart, and the HP 9144 is listed as having 'NONE': HEWLETT-PACKARD, HP9134A NONE HEWLETT-PACKARD, HP9142A, HP9144A/M NONE HEWLETT-PACKARD, HP9145A NONE Although IOTAMAT format tapes are listed elsewhere on the table at: http://www2.imation.com/dsp/cmptblty/dc_drv.html Could it be that Imation is hiding HP's 'dirty little secret'?

Steve: You have a working hp-9000? What model? What OS are you using? If it's a 68020 or higher, I *really* want to talk to you!

Maybe 1969? Anybody got a copy? It may have appeared in a Niven reference earlier, I don't know. - Mark

New Collector in Need of Help!

by mrdos＠swbell.net

I am kind of new to the collecting game. I am in need of some help. I need someone to tell me where I can find older and larger computers. I have a lot of micros, but now I am looking for bigger game. I have decided to focus my collection on older mainframes and minicomputers. Can anyone point me to sources? I found a local business that has older and larger computers, but the owner and I didn't hit it off. It's really a shame. He had some great stuff. While I was there I had to watch the workers scrap what looked like a very old classic control panel. Also, someone recently offered me a UNIVAC System 80. Anyone know anything about it? Is it something worth having in a collection?

Finally got a "straight" DF32 yesterday - bandwidth saver - many messages inside

by dylanb＠sympatico.ca

Looks like the PDP 8/S will be running a lot more than FOCAL in the near future. Yesterday in our snow storm I picked up: DF32 with docs and "Disk Monitor" paper tapes. This is the first series DF32s with the "R" series modules and no "8I switch". This DF32 has all the interface hardware to connect to the 8/S. This unit was wrapped in plastic and was used as a spare - it looks like it was used very little. I also got a new spare disk for it if I need it. But... the DF32 needs 13 I/O cables to connect to the 8/s. Anyone still selling these kinds of things? 500+ flip chip spares - mostly R (mostly the #s used in the CPU of 8,8/S) and a bunch of A,B,K,W,Z.. no Ms :-) If anyone is looking for any kind of transistor Flip Chip I am sure I can help. I have over 800+ spares now for this system. Hundreds of Flip Chip Test Specs/Schematics - every possible module I have seen. H901 Flip Chip Patch Panels - These are really sweet. You basically plug the flip chips in the back and use banana plugs in the front. Also, (I didn't know this at the time) hundreds of those "plastic" cards for the front of the H901 to make it easy to wire circuits. More Paper tape software - A lot of old DECUS stuff for the 8/s (old dice game, 5,5/8,8), etc.. Two trays of Disk Monitor and PAL III-D. I STILL NEED MANY MORE PAPER TAPE TRAYS! A half dozen more PDP 8/S software manuals. A data General Nova 3 with 2 40 series drives, paper tape high speed reader, and more docs, disks. Another teletype by Leigh (ASR-33)... This one is nice as it has seen almost no use.. Also, 2 more sets of schematics and serice manuals for this teletype. A couple of weeks ago I picked up another PDP 11/34 with 2 RL02s... Next month I will be getting at least one Straight-8, a bunch of Honeywell 316 systems.. I am still waiting to find out which mystery IBM system I am picking in in the near future (was purchased before '68). ---------------------------------------------------------------------------- ------------------------------- Questions: Is there a company that still sells I/O negibus cables? Has anyone here worked with Disk Monitor? Any special tricks to setting it up or using it? ---------------------------------------------------------------------------- ------------------------- Notes: I am building a quick testing station with the H901s with the 8/s so I can quickly fix these Flip Chips so I can provide a list on my website for anyone who needs one. I got a dedicated internet line now so I will have the 8/S connected to telnet soon. I am hoping to have the drive up and running in a few days so interested people can connect to the 8/s or a Nova. If I can get a good 220V->110V transformer then I can run a couple of PDP 11 systems too. I will update the webpage over the next few weeks to catalog the parts and software I have to help others with their old transistor computers. ---------------------------------------------------------------------------- --------------------- Updates to members here (trying to save bandwidth) I am just starting to move my personal collection from storage and have found many versions of complete sets of documentation for RT11, RSX-11M/PLUS, and RSTS/E - ver 7.0,9.0, etc..) also many original distribution sets for many of the above PDP 11 O/Ss. As I am trimming my collection of minis pre '73 (unless they are REALLY something) and many 11s. I am not going to waste anyones time waiting for "will trade for" or anything like that... reasonable $$ will take it. Kevin: Will get back to you on the 11/45,TS03 this week. Chuck: I am going to storage this weekend. I will look for the RK8E cables for you. I don't need them as I don't like any "IC" PDP-8.. well, maybe an 8I. ---------------------------------------------------------------------------- ---------------------------------------------------- Enjoy! john Enjoy...
