Seeking manual for Farallon Ether10-T Starlet/16 hub ($$$)

by sellam＠vintagetech.com

I'm seeking the manual for a Farallon Ether10-T Starlet/16 hub (circa 1994-1995). I'm willing to pay $50 for it. If you have one, please contact me directly (and immediately). Thanks! -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

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)

HP9133D disk replacement.

by jos.mar＠bluewin.ch

Closely related to the previous post : I actually have an ST419, but is in use inside a HP9133D. Looking back to old classiccmp articles indicate that it is not easy to replace the ST419 by other MFM drives of different geometries. Has this changed ? i.e can somebody report a success in replacing the internal drive of an HP9133 ? Jos

QUME DT/8 - current progress

by jzg22＠drexel.edu

Ok, thanks to many people calling my foul on terms of how the drive works, I have figured out what I need to get it up and running for the most part. I wired up a power connector for the spindle motor and verified (first with a meter, then by applying power) that indeed the spindle motor works properly. Now: I could use verification that the diagram for wiring the 50 pin 8" shugart connector to the 36 pin 5.25" shugart connector which is in the cp/m faq (http://www.faqs.org/faqs/CPM-faq/) is correct. Secondly, I cannot source one of those ?locking? Shugart DC power plugs to fit into the connector, the connector which looks like (paste in notepad): _________ | | | 0 0 0 | |__ ____| __| |____ | | | 0 0 0 | |_________| I'm wondering if I should just solder wires to the pcb to supply gnd, 5v and 24v, or does someone know where I can get one of those plugs which mates with that connector, or perhaps has one spare? Thirdly, what should I set the jumpers and fuse-block to, to allow this to work properly with a catweasel or anadisk? Thanks for all the help so far! -- Jonathan Gevaryahu jgevaryahu(@t)hotmail(d0t)com jzg22(@t)drexel(d0t)edu

That explains why you could use an older drive that could be used with an XT controller, on an AT comntroller, but *NOT* vice-versa! I was totally unaware that the fourth head-select line on the bigger drives had been previously used for RWC. > >I don't know anything about the HP9133D, but I did fiddle with >plenty of MFM and RLL drives on ISA controllers and non-PC >controllers (DEC RQDXn, Commodore D9060/D9090, Dialog DQ614, etc., >etc.) There was no hard and fast rule that X drive could always >be replaced by Y drive of a larger size, but there were many >specific cases where it worked - one I've done is replacing a >Tandon TM602S with a Seagate ST225 in a Commodore D9060.

OKay, looks like the 9133 wants a drive that supports RWC (or, at least, does not have a fourth head select bit!). Looks like the write precomp has to match also. Wow, I must have led a sheltered life: This is the first instance I've seen where the RWC and precomp actually have a discernable effect. I'll have to consult my drive guide to confirm this . . . .

last call for free-for-shipping stuff

by dgriffi＠cs.csubak.edu

I offered some stuff here as free for shipping. They were claimed, but the claiments seem to have disappeared. This is your last call. All of this stuff is packed and ready to go. I'm starting a "Free For Shipping" page at http://frotz.homeunix.org/freestuff/ beginning with the below-listed items. Does anyone have a cleaner idea for doing this? Is the classic computer marketplace back up? * Morrow MicroDecision 3 with two extra motherboards. When turned on, the power supply hums but nothing else happens. Maybe with the two spares boards you can fix it. Two floppy drives are present. I never got a reply from the one who wanted this. Weight 25 pounds. * UniPlus UNIX manual set. It seems complete. This one was offered in March. Claiment was contacted a couple weeks ago who still expressed interest (you know who you are). Weight 11 pounds. * Empty 8-inch floppy drive cabinet with power supply. I forgot who wanted this one, so I'm tossing it to you. First email gets it. Weight 13 pounds. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting.

VAXstation keyboard on a Wyse terminal?

by dgriffi＠cs.csubak.edu

On Ebay auction number 110304716214 is what is claimed to be a keyboard for assorted Wyse terminals with an RJ-9 jack. However the keyboard shown looks more like a VAXstation / vt220 keyboard. I'm not talking just about the layout, but the case too. I have some VAXstation keyboards already. Dare I try them with my Wyse 99GT? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting.
