Network question

by cclist＠sydex.com

I'm beginning to wonder if it's time I upgraded my home network. The NICs on most of the machines are 100BaseT, with the odd old machine sporting a 10BaseT. But it's the hubs I wonder about--two old National Semi 6-port Datamover 10BaseT units coupled together with a 10Base2 (coax) link. It's that coax that I dread replacing--it goes between floors and snaking it through the walls was a real chore. My DSL speed is 1.6Mbps, so I'm thinking that there's little reason to upgrade the setup. Am I thinking correctly or am I likely to see an improvement in internet access speed if I upgrade? Cheers, Chuck

Archive your Apple floppies at the W6TRW swap meet, January 2007

by adamg＠pobox.com

ARCHIVE YOUR APPLE FLOPPIES AT THE W6TRW SWAP MEET, JANUARY 2007 Even if your Apple IIe is long gone, you'll soon have a chance to get at your old data again, when Device Side Data (www.deviceside.com) holds the second public demonstration of a new USB floppy interface. USB floppy drives are widely available, but those currently on the market only support 3.5" disks. The new interface, due to be released later this year, connects to 5.25" drives. It will also allow the owners of modern computers to read a variety of old disk formats that ordinary floppy controllers no longer support. The demo will take place on Saturday, January 27th, 2007, at the famous W6TRW swap meet in Redondo Beach, California. Attendees are invited to bring along a few disks and have image copies made. The final product will read many disk formats, but the prototype only reads Apple II disks, so please leave your IBM or CP/M floppies at home for now. The W6TRW swap meet runs from 7 AM to 11:30 AM in the Northrop Grumman parking lot near the intersection of Aviation and Marine in Redondo Beach. There is no fee to attend. Once there, look for the spinning disk in row C. Besides Device Side Data, many other vendors will also be present, with a wide range of equipment for sale. This is an outdoor event and will proceed regardless of weather. Please carry your disks in waterproof bags in case of rain.

HP 7200A Plotter and DEC VT50 terminal

by wacarder＠earthlink.net

Does anyone out there have a Hewlett Packard 7200A plotter (made around 1972) or a DEC VT50 (not VT52) terminal? I am looking for both of these items for my classic computer center. Thanks, Ashley Carder http://www.woffordwitch.com

high school and timesharing

Eventually, we got caught. This reminds me of an interesting phenomenon we discovered in 1974... the high school had an ASR-33 connected via a leased data line (telephone with acoustic coupler) to a PDP-8/E running TSS/8 at Clemson University, 60 miles away. I can't remember exactly what the code was any more, but it was a very simple patch -we would deposit a mere three words at location 307 (octal) and execute it (ST 307), and the terminal would log on another job. So you'd have two accounts open simultaneously on the same TTY! And if you logged off one account the other would still be open so you couldn't log off both... they'd have to reboot the system to kill it. Any TSS/8 gurus know how we might have done this? We also "inadvertently" deleted the contents of one of the library DECtapes once... there was a "ZAP" command that zeroed out the tape, so naturally we would type in "R ZAP" frequently, and get the expected "WRITE LOCKED" error. One day, though, it actually did it =:^0 Guess the operator forgot to flip the write lock switch! -Charles

Recovering Cassette Tape Records

by lee＠geekdot.com

> Maybe the 680 and it's basic isn't fast enough for my program? This is quite possible as interpreting decimal numbers takes a fair bit of processing. You may like to try this .. 1 A=61456:B=61441:C=61457:D=1:E=0 2 IF (D AND PEEK(A)) = E THEN POKE B, PEEK(C) 3 GOTO 2 .. which should speed things up a bit. Lee.

Addition to cassette post earlier and 6800 assembler questions

by grant＠stockly.com

I just modified my program to get rid of the polling. It did not really speed up the display of characters. ; ) I can now see the full records with some duplicated digits here and there. Its interesting that the program below free running can only process characters at 300bps 1 POKE 61441, PEEK(61457) 2 GOTO 1 At a 500Khz clock thats over 1000 clock cycles per loop. SO THIS IS HOW Micro-Soft got started with slow software??? ; ) So any suggestions on getting started QUICKLY with 6800 assembler? Maybe one that outputs in Motorola punch tape format??? I want to archive Altair 680 KCACR basic before anything else happens to this tape. I had about 5-6 failed loads this weekend and I don't want to risk loosing this KCACR basic! : ( Grant

I still have this slick Nakamichi 7 disk scsi CD changer with audio outputs on the back. Something like MBR-7?? I wish I had a killer application for it. I wonder if it has enough front panel control to use it as an audio CD player without connecting to the scsi bus at all-- something like I'm doing with my NEC Multispin 6x caddy type CD drive.

Closet-cleaning

by rcini＠optonline.net

All: I was doing some closet-cleaning in the shop this weekend and came across a few things I have no use for any longer or were bought for projects that never got off the ground (and probably won't). If anyone's interested in anything, please email me off list. Shipping to the US only is not included. Trades considered. * Seagate 9gb full-height SCSI hard drive (new but unused/untested); ST940800N: $10 * Compaq-badged external DLT drive 5/10gb (SCSI-I; working last time used): $25 * Panasonic 616 phone system with 4 keysets (untested but bought working). I have manuals in electronic form: $50 * STD-BUS 14-slot card cage with assortment of cards (2 analog, 2 digital, 2 relay, Z80 CPU and DSKY. May have other cards in it). I think I have docs for most of the cards and a disassembly of the ROM. NASA surplus. All cards should work but it was some sort of data acquisition or process control system so I never finished fully decoding the ROM to see what it did. $75 * SpareTimeGizmos SB6120 PDP-8 fully built and working in a Lucite case. All that's needed is 5v adapter. Includes CF adapter and 16mb CF card with four disk images. $250 (reflects actual costs of partial kit and parts I bought). * TI-74 BASIC-Calc system. Includes unit, PC324 printer and AC adapter. I will also include CD of random information and programs that I had collected. $40. I'm looking specifically for a Tandy CM-1 color monitor for my Tandy 2000 and a small self-contained PC/104 SBC (stand-alone -- not for use with a backplane) with at least a 486 CPU. I'm also looking for an older Mac Mini (1.42ghz version with Airport/Bluetooth). Thanks.

SCSI CD cabinets

by tpeters＠mixcom.com

Oh my, what am I going to do with these MDI SCSI CD boxes? I have 3 or 4 of them, each one containing seven CD-ROM drives, a power supply, and some kind of logical unit controller, so all 7 drives appear a LUNs under one SCSI address. The drives are Toshiba XM-5301B, a 4x tray-type (doesn't need caddies) that works sideways or in the more usual orientation. Specs here, from http://www.netcomdirect.com/tosxm4xfonco.html CD-ROM Mode 1 -data discs CD-ROM Mode 2 - data discs CD-DA audio discs CD-DA/ROM - Mixed mode/combined CD-ROM XA and Photo CD (Single and Multisession) CD-Bridge (White book, Video CD) CD-I, CD-I ready The cabinets are 17" but with ears for std rack mount, 7 inches high, depth behind the rack 20 inches.

Altair 680 CSAVE Problems!@ : (

by grant＠stockly.com

I'm having a ton of trouble saving a program on a cassette tape using Altair 680 basic. Was there a KCACR basic made without the CSAVE command? My basic appears to have a CSAVE command, but it won't accept the name!!!!! : ( I'm sending this to two groups. I've been at this problem for hours now... : ( I'll post a transcript below. Let me know what I'm doing wrong! : ( -------------------- .J FD00 (cassette bootstrap rom address) (basic loading) (basic loaded) .J 0000 (run basic...) MEMORY SIZE? TERMINAL WIDTH? 80 WANT SIN-COS-TAN-ATN? YES 9604 BYTES FREE MITS ALTAIR 680 BASIC VERSION 1.1 REV 3.2 --KCACR-- COPYRIGHT 1976 BY MITS INC. OK 10 PRINT "HELLO" 20 GOTO 10 CSAVE A ?TM ERROR OK -------------------- TM is a type mismatch error. SM is for a command it doesn't understand.

A ?SN ERROR OK -------------------- Am I wrong assuming that because it gives me a TM error instead of SN that it is "trying" to work? I get the same things for CLOAD... How in the world are you supposed to save something to tape! : ( If I have the wrong version of basic, anyone have the right one? What will it take for me to get a copy! : ) (first smile in this e-mail... ; ) ) Thanks, Grant

I did a quick search on google and came up with 300 links (searching for "Exatron Stringy Floppy"). Unfortunately, I was unable to confirm what the ESF's were made of.
