Hey everyone, I just wanted to announce thta I will be opening a new Rainbow 100 website on Saturday, Feb 8. The site is located at: http://www.classiccmp.org/rainbow Right now, all that is there is an announcement. I hope everyone will take a moment top visit once it's open. I haven't been keeping up with everything in the Rainbow commumnity. I noticed that all the schematics have been posted on the Update (ftp.update.uu.se) archives. Who took the time to do this? I just wanted to thank them. Anyway, visit the page if you get a chance! Thanks! -Jeff jba(a)sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org

Converting .tap files to real tapes

by cmcnabb＠4mcnabb.net

I've hacked together a 2.11 BSD C program (nothing special, should work on other *nixen) that takes a .tap tape file and spits it onto a real tape. I've tested it with both a TK50 and a TS05 tape drive. It even successfully wrote a bootable TK50 format XXDP 2.5 tape. I'm going to be cleaning up the code and posting it on the web, but for those who can't wait, here is the raw code. It is left as an exercise to the reader to figure out where my MUA breaks the source code lines. ------------ Cut Here -------------------- /* detap.c - 2003 by Christopher L McNabb */ #include <stdio.h> #include <strings.h> #include <stdlib.h> #include <fcntl.h> #include <sys/file.h> #include <sys/inode.h> #include <sys/ioctl.h> #include <sys/mtio.h> main(argc, argv) int argc; char *argv[]; { int infile,outfile,ctr; long int offset; long int records=1; long int filecnt=1; long int reclen; long int reclen2; void* buffer; struct mtop tapeeof,taperew; ctr = 0; taperew.mt_op = MTREW; taperew.mt_count = 1; tapeeof.mt_op = MTWEOF; tapeeof.mt_count = 1; if(argc < 3) { printf("Usage: %s infile outdev\n",argv[0]); exit(-1); } infile=open(argv[1],O_RDONLY); if(infile < 0) { printf("Could not open %s\n",argv[1]); exit(-1); } outfile=open(argv[2],O_CREAT | O_RDWR | O_TRUNC,IREAD | IWRITE); if(outfile < 0) { printf("Could not open %s\n",argv[2]); exit(-1); } printf("Rewinding Tape\n"); if( 0 > ioctl(outfile,MTIOCTOP,&taperew)) { printf("\nMTIOCOP REW ERROR\n"); exit(-1); } offset = 0; read(infile,&reclen,4); while(1) { ctr ++; if(reclen == 0) { filecnt++; if(0 > ioctl(outfile,MTIOCTOP,&tapeeof)) { printf("\nMTIOCTOP EOF ERR\n"); exit(-1); } read(infile,&reclen,4); if(reclen == 0) { printf("\nEnd of Tape\n"); close(outfile); ioctl(outfile,MTIOCTOP,&taperew); break; } records=1; continue; } buffer = malloc(reclen); read(infile,buffer,reclen); read(infile,&reclen2,4); if(reclen != reclen2) { lseek(infile,-3,L_INCR); read(infile,&reclen2,4); if(reclen != reclen2) { printf("\nHdr1 and Hdr2 do not match\n"); exit(-1); } } write(outfile,buffer,reclen); fprintf(stdout,"Total Records: %6d File: %6ld Record: %6ld Record Length: %6u\r",ctr,filecnt,records,reclen); fflush(stdout); free(buffer); records++; read(infile,&reclen,4); } close(infile); close(outfile); } ------------------- SNIP -------------------------- -- Christopher L McNabb Operating Systems Analyst Email: cmcnabb(a)4mcnabb.net Virginia Tech ICBM: 37.1356N 80.4272N GMRS: WPSR255 ARS: N2UX Grid Sq: EM97SD

large disk platters?

by cmurray＠eagle.ca

Hi Jules, To my knowledge the largest hard drive platter was 24". IBM the inventor may have produced an experimental platter of ~1 m as a demonstration project to management and maybe these platters were 'sold' or distributed to IBM employees?

VAX 11/750 available in TX (?)

by gunther＠aurora.regenstrief.org

Hi, I was looking at a vendor site and it looks like they are offering an DEC 11/750 for $158.76. It's not quite clear, but since I don't have room for one I cannot simply order it. If you want it for the price, you can go on their web site to just order it and then call and ask them that you want to pick it up, that way you can find out what really they offer here and if it's not a real 11/750 system you can jump off (but if it is, you have a pretty good price.) regards, -Gunther

US Gov't/Navy DEC clearout

by alanp＠snowmoose.com

DRMO is the group at a US military base responsible for taking care of surplused equipment. Some of it ends up being auctioned, for example, through web sites like www.govliquidation.com. Some of it ends up disposed of as scrap. alan ---Original Message--- From: cctech(a)classiccmp.org To: cctech@classiccmp.org,cctalk@classiccmp.org Date: Thu, 20 Mar 2003 10:05:15 -0000 Subject: RE: US Gov't/Navy DEC clearout Hi folks, Got this from a contractor working for the navy; how he found me before he found any other place that collects DEC stuff I don't know :) Replies to email address he's given me (suttonmr(a)navair.navy.mil), particularly as I don't know what the DRMO is!

aviion 4000 info

by classiccmp＠crash.com

pmulry wrote: > I recently aquired a Data General 4000 series server [...] It's highly possible that the NVRAM's lithium battery will have died ("gone flat") by now. This is the case with both the AV410 and AV4300 I have. My AV530s/5500 seem to be okay, but it's just a matter of time before they face the same problem. The machines with dead NVRAM will give some cryptic indication of the problem like printing "IDPROM" and nothing else, and refuse to initialize/boot on power-up. 'r. bear stricklin' was collecting NVRAM dumps for analysis, so we can try to load usable data into replacement parts, but I've no idea where that stands. I haven't bothered getting a part to see if, like Suns, the machine will function at all with an uninitialized NVRAM. Anyway if you search the archive for his name or Aviion I'm sure you'll find the relevant post. Or head to this URL: http://www.bears.org/~red/museum/aviion-nvram.html The 88k Aviions were frequently SMP capable, though unless you've got rackmount or square/big deskside units they're probably just 2-way. If you think the daughter card on yours is a second CPU complex, look for a chip marked 88100 or 88110; those are the CPUs. The 88200's or 88410 are cache/MMU chips. DG/UX will support SMP out of the box. It's a decent enough SVR4 implementation, with X11 (R?) and some sort of logical volume system. If you're looking for media I may be able to help out, contact me directly/off-list (smj0302 _ crash _ com). Martin Marshall wrote: > http://www-csc.dg.com/csc If you dig around under there, there's a wealth of PDF files about various models. Operations guides, some about installing options and upgrading, low-level programming for a few models. There's been sporadic interest in getting *BSD running on the Aviions, but little activity. OpenBSD runs on several Motorola 88k boards, and I've recently managed to assemble the parts for a complete system, but that's as far as it's gone. I have no history porting OSes, and I'm much more focused on trying to find a job now, so you don't want to hold your breath waiting for me... --Steve.
