I have a rackmount Sun-3/280, pretty loaded up, that I would like to move out. I think I have a SPARC board for it as well, to turn it into a 4/280. No disk, but I think the interface card is there, along with a few others. The thing is a cube, a little under a 20 inches on a side or so. I have the front panel. I think it even has a 1/4 inch tape drive in the front. The last time I powered it up, it passed its memory test OK, but that was almost 10 years ago (!). -- Will in 10512

If it isn't, "RUN $SHUTUP" will do the same deal. As others mentioned, LB:[1,2]SHUTUP.CMD is invoked as a part of the shutup procedure, and shouldn't be invoked by hand. > TO change admin password how, and which account again? "RUN ACNT" if ACNT is installed. Otherwise "RUN $ACNT" will do it. The "SET PASSWORD" command is something that only exists in RSX-11M-PLUS, but if so, then it works just as fine from MCR as from DCL by default. ACNT is the general account management program. From a privileged terminal, you can change any account. In 11M, you can only change your own password with ACNT. In 11M-PLUS, ACNT is not usable by non-prived terminals. And there isn't any explicit admin account in RSX. The closest would be [1,54], if it exists. It does by default, which is why I mention it. But there are no problems with just deleting that account if you want to. Any account with a group number <= 10 is a privileged account. What this means is that when logged in, the terminal will have the PRIV bit set. Other users will have it cleared. Most things go on the terminal info bit when checking for privs. Run ACNT, and you can list all accounts, and see which exists with privs. > If I add a 8line mux (DHV or DZV) what the procedure to get > system to install and recognise it. Phew, big question. In short, you have two ways: 1) Do a full sysgen, which includes all the devices you want, and you'll have it. This will take a couple of hours, and literally hundreds of questions. A manual is almost neccesary. 2) Just build the device driver and load it. This requires that your system have been generated with loadable device drivers. You still need to figure out how to build the device driver. There are commands scripts that do these things, but they expect to be called as a part of SYSGEN, so doing it by hand will require some hands on fiddling. If you want a device driver to be abailable each time you boot, you need to add it to the system image you're booting. That is done by VMR. VMR is done as a part of SYSGEN as well, but if you build stuff yourself, you'll have to either add them in VMR as well, or load them at boot time in the startup script. > On line DOCs to refresh memory from? I think I saw that SRI now have some RSX manuals online, and of course, we also have bitsavers. There is a whole manual just on the SYSGEN process. Read it. :-) > I'm most comfortable with VMS, Ultrix and RT-11 but never > bothered with RSX for a home system. VMS knowledge can be of some help, but not much of anything else. RSX is so much fun.

MFM or ESDI QBUS controller for one PDP-11/23 PLUS

by hoelscher-kirchbrak＠freenet.de

Sergio, I made good experience with the SRQD11 Controller for ST506 (=MFM) disks made by the Australian Webster Computer Corporation. It can interface one disk (genuine DEC RDs or any other MFMs) to your PDP-11 or MicroVAX without any additional boards or panels. Mine has been running as well in my PDP-11/03 [RT-11] as in my MicroVAX I [VMS], which is VERY picky about disk controllers. Another good choice would be an Emulex QD21 for ESDI disks or even an Emulex UC07 for SCSI disks (if you find one). Ulli

seeking ms/pc dos 1.x

Can someone point me to somewhere I can find bootable disk images for MS/PC DOS 1.x? I found vetusware.com, but the quality is spotty and frequently uses obscure compression programs. -- David Griffith dgriffi at cs.csubak.edu

100TPI floppy disk drives

by dm561＠torfree.net

------------Original Message: Date: Tue, 9 Oct 2007 20:21:53 -0400 From: "Andrew Lynch" <lynchaj at yahoo.com> Subject: 100TPI floppy disk drives Hi, I recently bought this S-100 chassis with four Vector Graphic boards. Based on what I gathered from searches, the Vector Graphic system uses 100TPI floppy disk drives. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=ADME:B:EOIBSAA:US:1 1&Item=320164273848 Will anyone confirm which disk drives are compatible with the Vector Graphic floppy disk controller? I believe those 100TPI drives such as the Tandon TM-100-4M. There are probably others from Micropolis as well so if you know of some please include them in a response. In addition, I would like to extend the Catweasel hard sector decoder software concept to the Vector Graphic 16 sector 5.25" hard sector floppy disks. I have written Catweasel floppy disk decoder software for the NorthStar which now seems to be working pretty good. Also, the Catweasel Heath project is coming along although not as far along as the Catweasel NorthStar software. It can make images of Heath SSSD floppy disks. Does anyone have some 100TPI floppy disk drives they would be willing to sell? I think I will need at least two or three drives total so even if you have only a single drive you can part with, I would appreciate an offer. Thanks! Andrew Lynch ----------------Reply: FWIW, my Vector MZ has a pair of Micropolis 1016-II drives which AFAIK are SS 77Trk 100TPI drives, with a Vector Graphics Disk Controller marked FD CONTROL B MICROPOLIS. However, I believe Vector Graphic used different drives in some later models, even soft sector in some if I'm not mistaken. mike

AED (was PDP-11 graphics products)

by aek＠bitsavers.org

> Years ago, I had an AED 767, which I suppose was a cross between a > graphics subsystem and a graphics terminal. > Has anyone else worked on those? I worked at AED from 84 - 86 and was the architect of the AED 1280, which was their last graphics terminal. The 767 is a modification of the AED 512 which used 64k instead of 16k DRAMs and 4x the frame buffer space. The original designers of the 512 did their own version called the Jupiter 7. It has a 6502 processor and an RS232 or 'AED' (parallel intf, the same as the AED 3100 floppy ctlr) parallel interface. I still have most of the docs/firmware for these. AED terminals were popular with chip designers. The Berkeley CAD tools suite supported them, as well as VTI.
