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

Radio Shack/Science Fair bonus

by erd_6502＠yahoo.com

I recently won an auction described as a "Science Fair Junior Electronic Lab 10 in 1"... the picture showed a couple of blue grid boards which were, AFAIK, not part of a 10-in-1 It turns out that in addition to the 10-in-1, there was an entire (and a partial) "Science Fair Junior Project Board Kit" (cat no. 28-153) - one manual, two plug boards, one IC board (14-pin socket + 14 springs) plus a double handful of mixed loose components. The components are somewhat interesting from a historical perspective - there are several flavors of transistor sockets, several segmented LED displays (some on PCBs as from an LED calculator, some in DIP form), mercury switches, reed switches, and a bag of resistors with a "King Kits" card from Poly Paks. I'm curious if there's a repository of ancient Radio Shack kit manuals out there - I did not get a manual for the 10-in-1 (cat no. 28-225), but at least I got its box (covered in packing tape, grrr.) -ethan The New Yahoo!

(Fwd) MINC-11 available (UK)

by pete＠dunnington.u-net.com

This is just to remind anyone who saw my post a few days ago, and hasn't yet decided they need to rescue this MINC... > DEC MINC 11 > > This is a self contained mobile unit based on a PDP11. > > It has an ADC, Digital I/O and clock. VT05 VDU on top of it. Dual 8" > floppies. Era 1980. Quite heavy!! > > It's available up until 21st April - maybe a bit beyond if you really > want it. The deadline was extended until next week, but it is now a firm deadline -- the owner (not me) is in Edinburgh, and is moving office next week, to a new site. There's no way the MINC can go with him, and there's probably soe other stuff available as well. Surely someone can rescue this machine! -- Pete Peter Turnbull Network Manager University of York

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

Vaxstation 2000 and VXT software, 4 plane color supported?

by sgust＠ithh.infoserv.de

Some time ago I got my hands on a Vaxstation 2000. I searched for some Information about the machine and read somewhere that it should be possible to run the VXT X terminal software on the VS 2000. The only version of the VXT software I found was in VMS BACKUP format which I could not read. So I put NetBSD on the machine, it runs disk-less from a PC with Linux. Last week I searched again and found version 2.1 of the VXT software in tar format, so I could finally try it. It works, but only in monochrome. If I put my VS40X 4 plane color option board into the machine it seems to crash when it has finished loading. Some pixels get randomly set and the machine does not react on the break switch at the back. Is the color board supported by the VXT software? Or is it a firmware issue? My board has version 1.4, are there newer versions available? Or even older version? Anybody want to swap firmware dumps? The loading process via mop often takes several retries or even fails completely, especially when loading the full VXT.SYS version. It seems to work better if there is some load on the Linux server, perhaps the mop daemon sends the data too fast. Has anybody else seen this effect? Is it possible to use the VXTLDR.SYS to load the rest of the software via TCP/IP? I know nearly nothing about DECNET and don't have any other DEC equipment to run it on. Another minor problem is that I don't have a real DEC mouse. I use a small Atmel AT90S2313 micro-controller as protocol converter. It currently only supports one mouse button and needs an Amiga mouse, but I plan to adapt it to PS/2 mice. The information about the DEC mouse protocol I found leaves some minor questions. How many packets per second does a real DEC mouse send in stream mode? I chose to send 60 per second, as this was easy to implement via the timer0 interrupt on the Atmel. What does a real DEC mouse return as revision and manufacturer code? I return 0 for both but fear that there may be some software which expects real data. Soeren Gust
