Listing of 60s mainframes/minis with CRT displays?

by wgungfu＠gmail.com

Hey guys, we're on the next phase of our paper we're presenting at a conference soon and are hoping to collect a listing of 1960s era mainframes and minis that had CRT displays available for them. We're obviously already aware of the various DEC models released in the 60s that had them, but we're looking for other brands now. If you guys would be so kind to help us out (since we're in a bit of a time crunch) and share the following, it would be awesome! Computer maker and model: CRT maker: Dot, vector, or character display: Thanks! -- Marty

Tools in the Computer Operator's Desk Drawer

by nf6x＠nf6x.net

I have this vague memory that back in the day, any well-equipped computer operator would have a tool in the desk drawer which trims the end of a mangled magtape to a nice, neat curve. Do I actually remember that, or did I make it up? As I get older, my imagination is getting better than my memory, and it's getting a lot easier to vividly remember things that never happened. If such a tool exists, I want one! I recall another little tool (and I think I still have one somewhere) that was a give-away from the Sun User's Group. It was a little pocket-clip screwdriver with a flat blade on one end, a hex key for VME card mounting screws on the other, and "SUGtool" or something like that marked on the side. One of our printers in the computer room that I worked in at UCI in the late 1980s had a tool sitting about for punching the carriage control tapes for one of our old line printers. We had separate printer queues for letter sized and wide format paper, both pointing at the same printer. One of the operator's jobs was to frequently stop one queue, change the control tape loop and the paper in the printer, then enable the other queue. Write rings were littered all over the place, naturally. And then there was the suction-cup tool for lifting the raised floor tiles. What else might be found in the operator's desk drawer or sitting around the computer room? -- Mark J. Blair, NF6X <nf6x at nf6x.net> http://www.nf6x.net/

60s Mainframe/Mini Disk File Systems

by t.gardner＠computer.org

IBM famously introduced its CKD disk file format in the 60s; did anyone else (other than IBMs clones including RCA) support such a disk format? Specifically a disk format with a block (record in IBM terms) having a variable length key field (including 0 length) and a variable length data field. To the best of my knowledge everyone else used a fixed block (sector to most) size on a disk volume but my knowledge of most of the BUNCH is limited. Tom

How to create a CF boot DOS

by enrico.lazzerini＠email.it

Hello to all, frankly I think I'm in a loop. Let's see the summary . Ultimate goal : to install a Compact Flash card <http://www.memoryc.com/images/products/b/adata-2gb-cfc-speedy_4711.JPG> http://www.memoryc.com/images/products/b/adata-2gb-cfc-speedy_4711.JPG on a cf- ide adapter <http://img.dxcdn.com/productimages/sku_0711_1.jpg> http://img.dxcdn.com/productimages/sku_0711_1.jpg on a controller PTI- 227B V2 <http://www.rainbow-software.org/manuals/pti-227b.html> http://www.rainbow-software.org/manuals/pti-227b.html into an IBM PC AT 286 5170 <http://www.vintagesbc.it/?page_id=838&gtlang=en> http://www.vintagesbc.it/?page_id=838&gtlang=en Not being sure of anything I have designed different steps. I ask for help for the first one that is : Make sure that the Compact Flash <http://www.memoryc.com/images/products/b/adata-2gb-cfc-speedy_4711.JPG> http://www.memoryc.com/images/products/b/adata-2gb-cfc-speedy_4711.JPG on a cf- ide adapter <http://img.dxcdn.com/productimages/sku_0711_1.jpg> http://img.dxcdn.com/productimages/sku_0711_1.jpg to boot on an old PIII PC <http://it.gigabyte.com/products/mb/specs/ga-6vxc7-4x.html> http://it.gigabyte.com/products/mb/specs/ga-6vxc7-4x.html that I normally use to transfer files between different diskette's formats and disk that has as OS Windows 98 and its relative DOS . I can also load on it a DOS 3.3 , and so on. If this works I will can try the union of CF + adapter + controller on the same PC and then follow again all into the IBM PC 286 . I premise that the PIII's bios made available to me to set the automatic recognition of geometry of the HD connected once and forever to be sure to not have discrepancies for HD and even for the Compact flash card at each turn on of the computer. Anyway from its bios I can always choose from which drive to boot from . Yesterday , I took an old IDE 6GB HD , I partitioned it to 2GB with a DOS3.3 ( with FDISK first and then with format / s ) so I launched Acronis CD to make a clone of the HD partition on the compact flash . It took a bit to do this perhaps to resize the copy . At the end , however, the boot did not work the same. It was the last attempt after days of testing . Imagining that on a compact flash perhaps the BOOT sector might be seen differently (being theoretically removable) compared to HD . I found an interesting document <http://thestarman.narod.ru/asm/mbr/STDMBR.htm#CHS> http://thestarman.narod.ru/asm/mbr/STDMBR.htm#CHS but it is too complicated for me . I thank you for all your straight. Otherwise, I give up . Enrico

Basic Four 410 / Microdata 1600

by ad＠ardiehl.de

Hi, i recently got a MAI Basic Four 210 from the Netherlands. The CPU now powers up, have not yet tried the 14" Piram harddisk. I would like to know if the CPU is working. It seems to be based on a microdata 1600 but equiped with dram and cmos ROMs. The machine has switches were it can be set to boot standard/alternate >from disk, tape or from a serial terminal. Since the tape drive has a capstan roller transformed to liquid and i have not yet tested the disk i would like to know how to boot from a terminal. I have not yet read the microcode proms nor have i checked if they are soldered or on sockets. Does someone out there have access to the cpu manuals that are stated in the service manual ? 1300 CPU Technical Manual, Document No. SM 1200 M1300 Series CPU Organisation and Description Reference Manual Pictures from the machine are here: http://www.ardiehl.de/basicfour/mai210/pics/small/ and the manuals are on bitsavers in pdf/mai, the service manual also contains the cpu schematics, the ones for the tape controller and the disk controller are included in the tape / disk service manuals. What do you think are the chances to get the disk up and running. (since i have no tapes of other software) All seems to be stored dry, no rust, nor a lot of dirt in the machine. Seemd to be powered on the last time more than 15 years ago. ---------------- Gr?sse Armin Diehl ad at ardiehl.de -- ---------------- Gr?sse Armin Diehl ad at ardiehl.de
