Just that way--like a floppy--there are address marks and sector headers that mark the beginning of each sector. At least that's the way most controllers work. Of course, since the data stream from an ST412 interface is just a raw bunch of pulses, one could record anything on a track that one wanted, within the electrical limits of the drive. Cheers, Chuck ----------------Reply: The Cromemco STDC ST506-type controllers are an example of a controller that *did* format/read/write entire 10K tracks (no physical sectors), with a four-track cache. m

Drivetec Floppy Drives

I've still got some of >the old Drivetec/Kodak drives and some media, but I'm not aware of ^^^^^^^^^^^^^^ Whoa, hold the phone here. Okay, I'm trying to solve a twenty-year- old mystery. So, you say the media for these drives were made by Kodak? Did they, per chance, have *triangular* notches in place of the traditional rectangular ones? I'm asking, because in 1985 or '86 I was at an electronics scrap yard in L.A., and saw a *very* large heap of these kinda strange looking floppy drives. I don't remember too much about them, but I just remember they looked *weird*. The media was made by Kodak (something I had never seen before), and the notch on the edge of the floppy disk was *triangular*. I figured it was some special media for bio-medical equipment, or for some bizarre photographic process, or something. Anyways, I never saw drives (or floppies) like that ever again, and always wondered about it. They looked brand-new, and the whole incident sticks out in my mind because I remember the owner was mad as hell-- apparently he spent a small fortune on these things, but nobody wanted them because they weren't 'standard'. _____________________________________________________________ Live the good life!

FrameMaker for SunOS

by mcguire＠neurotica.com

I have ten (yes ten) boxes of FrameMaker v5 for SunOS. Includes manuals, CDROM, I think even license keys. I only opened one box, but I assume they're all the same. If anyone wants all of them, they are free for the cost of shipping, probably $40 or so. Let me know soon or they hit the trash. I'm not really interested in breaking them up. Contact me off-list if interested. -Dave -- Dave McGuire Port Charlotte, FL

Help with Sun video

by snhirsch＠gmail.com

I'm hoping someone can shed light on this. For the past week, I've been battling to get my Sun Ultra-60 video switchable through a Belkin 8-port KVM switch. The monitor is a Samsung 214T 20" LCD. - Connect monitor directly to workstation with a 13W3 Sync-On-Green adapter (no passthrough of sync signals): Works fine. - Connect monitor directly to workstation with a 13W3 adapter that brings out H+V sync: Works fine. - Connect either of the above to a port on the KVM switch: Switch does not recognize that anything is connected and refuses to pull in the relay (I can hear an audible click from any channel with recognized video). The status LED on the KVM keeps flashing to say "no one there!". Obviously no video. - Purchase Belkin Sun adapter box from eBay and connect it between the U60 and the KVM: KVM recognizes that video is there and pulls in the relay. The monitor _seems_ to believe that something is there, as the blinking green "nothing attached to me" LED goes solid on. However, nothing ever appears on the screen. I tried all DIP switch settings on the adapter (connected to Sun monitor sense lines). - In desperation, connect monitor directly to HD15 port on the Belkin adapter: Same thing. Solid green LED, no display. The same machine worked perfectly through an older 4-port Belkin unit (that I've outgrown, thus the 8-port). What on earth am I missing here? I don't even see a common denominator, but am hoping that someone more familiar with the details of Sun video can give me a nudge in the right direction. On the subject of the Belkin KVM: Is it possible that their "detection" is simply looking for a grounded pin or a pair of pins looped back by virtue of the computer being connected? Maybe expecting a voltage? If I could trick it into activating the port, I could just feed through from the 13W3 adapter and be done with it. Naturally Belkin's site has no information at this low level of detail... Steve --

by lbickley＠bickleywest.com

I dropped by Weirdstuff today and found a clean Osborne and a dusty (but unusual) TI Terminal in their Bid Sale. You can see pictures of them via: ftp://bickleywest.com/ws/ or ftp bickleywest.com User: anonymous Password: your email address cd ws Here's the info on the WS bid sale: http://www.weirdstuff.com/sunnyvale/html/bid_sale.htm Note that you can FAX you bids to WS. The webpage doesn't say it - but they will ship items won in the bid sale. I have no monetary interest in the auction or sale of these items. I am a "regular" bidder at WS - but will not be bidding on either of these items (otherwise I wouldn't be posting them to the list, would I ;-) Cheers, Lyle -- Lyle Bickley Bickley Consulting West Inc.

DG Tapes: Nova Fortran IV

by julianskidmore＠yahoo.com

Hi folks, It seems to me that self-hosting 16-bit compilers for old minicomputers are very thin on the ground. Yet from my viewpoint they are interesting and worth preserving, because they are a good demonstration of what could be achieved using fairly limited hardware. Recently, I've been looking at the Data General RDOS Fortran IV compiler manual. It seems a very comprehensive version of the language, and it's actually Fortran '66 with some extensions, and looks very practical. However, the standard RDOS images for SIMH don't come with the Fortran compiler, only assembler. Here are the only two references I've found on the net for the Fortran IV tapes: http://www.chookfest.net/nova3/paper-tapes.html http://www.ludd.luth.se/~ragge/nova/swdocs.html How easy would it be to get these tapes transcribed; dumped onto an RDOS disk and made available for SIMH? -cheers from julz @P __________________________________________________ Do You Yahoo!?

DEC AlphaServer 8400 for Trade

by hoelscher-kirchbrak＠freenet.de

I will trade off my AlphaServer 8400 for a VAX-11/750. This is the AlphaServer 8400 current configuration: 8 CPUs = 4*Dual-CPU 300 MHz E2056-DA 4GB Memory = 2*2GB MS7CC-FA 2 KFTIA I/O Modules (4*SCSI / 2*Network) E2054-AA 1 Bus-Terminator E2034-AA 3 48V DC Power Supplies 303379602 3 BA356 StorageWorks SCSI-Boxes 12 DEC SCSI-Drives (RZs) 1 AlphaServer 8400 PCI Box There are some AlphaServer 8400 spares that will go together with the computer: 1 48V DC Power Supply 303379602 2 CPUs = 1*Dual-CPU 300 MHz E2056-DA 2GB Memory = 1*2GB MS7CC-FA 1 Bus-Terminator E2034-AA 1 Box BA655-AA The AlphaServer 8400 is in working condition, but without software and licenses. The only known deficiency is that the console CDROM drive (RRD45) does not open properly, but is nevertheless usable. The condition of the spares is unknown. The AlphaServer 8400 system is located in Northern Germany. What do I expect in return: - A VAX-11/750 in working order - 1MB VAX-11/750 memory - A working VAX-11/750 disk subsystem (controller & drive, any model) - A DEUNA or DELUA UNIBUS ethernet adapter All items are negotiable. The VAX-11/750 will become part of my private collection of VAX computers and will be used to run VMS version 2, 3 & 4, ULTRIX-32 and some old UNIX versions. Regards, Ulli (The VAXorcist)
