Need paper tape encoding format

by vcf＠vintage.org

Is there info somewhere that shows how symbols are encoded onto paper tape? Ideally it would include the actual hole positions like so: 8 4 2 1 A: * B: * C: * * (Note: this is not an actual example but just an example of the format I'm looking for. Of course.) Thanks! -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *

Creed Teleprinters

by dhquebbeman＠theestopinalgroup.com

Once upon a time.... There were a bunch of these in the early hobby channel, say, around 1981... the seller had complete instructions for interfacing them, and included some rudimentary code for using overstrikes to simulate characters bot available in its 5-level (Murray?) coding scheme. They were going for $150 at the time, and I still could kick myself for not grabbing one, they looked pretty cool. Anyone got a garage full of them? -dq

Also reminds me of "programmers" who can "write code" but seem unable to read other people's code. Has anyone else had this experience? I run into this sort of person all the time . . . Glen 0/0

Use of the tar command (in classic unix systems of course (^; )

by rhudson＠cnonline.net

Ok, Here's what I am doing for backup to DC tape drive.. ~500 mb per tape: tar -cvf /dev/st0 -L 500000 /root /etc (... mention many directories) is this correct for backup or do I need any other flags? How do I do an incremental? (This is assuming that I am using a "Classic" system running unix...) How do I recover a file? Thanks.

Not quite. It's white-with-colour then plain colour (or colour with a thin white stripe or rings), and the common order in Europe is T568B (aka 258A): white/orange pin 1 orange white/green blue white/blue green white/brown brown pin 8 I believe the common order in the States is to swap orange and green pairs, which is T568A. If you use one scheme at one end and the other scheme at the opposite end, you have a standard Ethernet crossover cable. ie, pins 1 and 2 are swapped with pins 3 and 6 but pins 4+5 and 7+8 are straight-through. > But for a regular CAT5 cable, as long as you use the same order for each > end, it'll work fine. Almost. You need to keep the pairs as pairs, on pins 1/2, 3/6, 4/5, and 7/8. -- Pete Peter Turnbull Network Manager University of York

Multiple floppies in one system?

Commands such as FORMAT, DISKCOPY and DISKCOMP ignore drive reassignments. Perhaps the MS install program did something similar to these commands.

OT: ClassicOffice Chairs

by dhquebbeman＠theestopinalgroup.com

Does anyone have a line on old office chairs with FOUR legs instead of the fscking OSHA-mandated FIVE legs? It is impossible to roll around in one of these without, when you roll back forward, having a single leg protruding such that it hits *anything* that might be in the way, like a table leg... grrr...

I want to buy a TU-58

by jhfine＠idirect.com

I am attempting to recover some files from a DECTAPE II cartridge. They are in RT-11 format, so the most useful drive would be a TU-58. Does anyone have a spare drive that they are willing to sell or at least rent for a long time? The one that I prefer is a dual desk top box with its own internal power supply and a 10 pin header on the back for connection to an RS-232 channel so it can be connected easily to a DLV11-J (or any other DL channel on a PDP-11 with some wiring changes). A TU-58 is normally standard with a PDP-11/44, so if the 11/44 is not in a state to be rescued, that at least if there is a TU-58 available, please contact me. They may also have been used with a VAX 11/780.

Nope, my first printer was a 7B -- about 1981 -- but it's long since gone. It cost me a lot less than $150! I'm sure I've mentioned before how I wrote a driver for a Sorcerer for it, and how I changed the positions of some of the type slugs to make overstrikes easier. -- Pete Peter Turnbull Network Manager University of York

Possibly. But if you work it out completely, I think you'll find you save very little.

Yes, but if it's single density, which is the only reason you'd read four sectors, the sectors are 128 bytes [100(8)] not 256, so it's still only 1000(8). -- Pete Peter Turnbull Network Manager University of York

Multiple floppies in one system?

by mtapley＠swri.edu

In the "useless trivia" category, DEC Rainbows all support 4 floppies (= 2 x RX50 drive) out of the box, though most came with only one RX50. IMPDRV, by Warner Losh, will let you hook up a 3.5" drive in place of one of those RX50's. However, I know of no way to get "normal" 5.25" or 8" drives hung onto the Rainbow, so I strongly suspect this is not of much use to you. - Mark

Need paper tape encoding format

by kapteynr＠cboe.com

The format depends on the program writing the tape, binary or text. In "Binary" tapes, the eight holes correspond to a "byte", which is just loaded into memory, byte-by-byte. The problem is that paper tape readers are error prone and any binary error was a potential crash. To solve this problem, the Altair Basic "Boot" loader starts with a straight binary tape. The straight binary formart continues for a few hundred bytes during which a "checksum loader" is read. Then a special binary code on the tape triggers a jump from the "boot loader" to the "checksum loader". You can recognize the blocks of the checksum loader on the tape, because every foot or two, you see a code that consistently repeats. Text format paper tapes are almost always simple, standard ASCII codes translated into binary. Text format can be recognized because, in those days, ASCII was almost always limited to 7-bits. This means that the tape has a column on one edge with very few holes -- that is the column 8. The other side is column 1. Here is a link to an excellent 7-bit ASCII table that I just found: http://www.neurophys.wisc.edu/www/comp/docs/ascii.html Here is a clip from it: Decimal Octal Hex Binary Value 065 101 041 01000001 A 066 102 042 01000010 B 067 103 043 01000011 C 068 104 044 01000100 D 069 105 045 01000101 E So with column 8 on the left, you read like this: (Holes in the tape translate to binary "1"s.) xOxxxxxO translates to 01000001 binary -- which is the octal 101 -- which is a capital "A". xOxxxOxO translates to 01000101 binary -- which is the octal 105 -- which is a capital "E". Most of us found "Octal" codes easiest to work with manually -- Hex became popular later.

Sometimes the 90-degree cable works best and sometimes the straight one works best. The 90-degree ones work nicely at the back of a VS4000 ... not so much spce is needed at the back of the box (vents are at the sides!). Same deal goes with the 90-degree vs straight ethernet connectors. Horses for courses. Antonio

ASSIGN (with the format such as "assign a=c" -- no colons allowed) "Instructs DOS to route disk I/O requests for one drive into disk I/O requests for another drive" (IBM DOS 3.30 Ref Manual). SUBST (with the format such as "subst g: c:\foo\bar") "Allows you to use a different drive specifier to refer to another drive or path." It's useful where a program does not recognize paths, but does recognize different drive letters.

RK05 Alignment packs

by lemay＠cs.umn.edu

Well, I've been searching for RK05 alignment packs, and though I've been very successful, I was hoping to find some at a cheaper price (hey, it never hurts to try...) Anyways, so far i've found 3 RK05 alignment packs available at various DEC resellers, but they are $150 each. And both 12 and 16 sector packs for $50 each for that matter. If someone is desperate enough to be interested at these prices, just let me know. -Lawrence LeMay lemay(a)cs.umn.edu
