MITS Altair 680 KCACR Cassette BASIC Recovered

by labomb_s＠yahoo.com

Hi Grant, >One 8bit ASCII and another forced to 7bit. This one attached has >been forced to 7bit ASCII. Both files WILL load into the Altair without >issue. The tapes are comprised of recorded ascii data (s-record format) ...so if you are just reading the data as is (vs. loading the data via a s-record loader) then you should probably get the same thing regardless if you use 7 or 8 bits. >It seems random which bytes had the 8th bit set and which >didn't. I assume that you are referring to the data in memory as a result of the ROM tape loader execution? If so, you will note that Basic has bit 8 set on many ascii text elements within the source. Microsoft Basic used the high bit set in the keyword tables for the code that searched the keyword tables. They also often used the high bit to determine the last character of message strings. > Also, there is what appears to be garbage after the S0 record. I >have no idea why. The tape has a bunch of 7Fs, then S0 and a bunch of >garbage, and then 00s. At the end there is some garbage too. The KCACR >ROM appears to ignore it. It appears that the tape is similar to the MITS Absolute Tape Load format. I'm guessing that your format is as follows: First ... Pre-leader - comprised of a series of bytes that represent the length of the tape checksum loader. For example, a series of 7F bytes would mean that the checksum loader is 127 bytes long. Second... S-record header record (S0) Third... Checksum loader - intended for those who do not have the kacr ROM. It should be 127 bytes in in your example. Forth... Tape leader - a series of nulls Forth... The actual code. There may be some garbage bytes appended, depending on how MITS dumped the tape (specifically, how long the address range specified to dump was). Fifth... Trailer - a series of nulls This is similar to the typical format used for MITS tapes (both paper and cassette based). Scott __________________________________________________ Do You Yahoo!?

altair 680 tapes

by grant＠stockly.com

Posted for comment, started off list: I have about 3-4 recordings of the tape. As well as a "reproduction" of the tape. I lifted the "transmit" leg on the serial chip so that it wasn't in the socket. Then I put a jumper from the receive pin to the transmit hole. While playing the tape into the Altair I recorded the remodulated data into the computer and made a note if there were no checksum errors. As the tape was being demodulated the KCACR was remodulating the data at the same time. I have never been able to get a computer recorded file to load into the Altair. This may be caused from a lack of audio amplitude? I was surprised that the KCS.EXE utility only found 3 errors in the cassette tape wav file but found 11,000 errors with the remodulated WAV file. There was a slight DC offset and a background hum (not 60hz) I'm STILL trying to figure out why I have a few 13 minute long and a few 10 minute long recordings of the SAME TAPE!!!! Once I am through with this process I will make a tutorial. I'll also offer to recover other people's tapes. I LOVE time capsules! : ) Grant >If you haven't done so already, back up your tapes to .wav files right >away! > >Just plug your cassette player into your PC and do some high quality >mono recordings (8bits @ 22050 samples/sec).

TCP/IP Testing help, Round 2

by mbbrutman-cctalk＠brutman.com

Happy New Year! I'm back at it again - I plan on doing better this time. (I've fixed the specific double delete bug that bit me last time, improved tracing quite a bit, and added a lot of consistency checking code.) Just like last time, all you need to do is telnet to 24.159.203.149, port 2301. Once again, that's my Linux box, but today it is forwarding port 2301 to my PCjr. The commands are slightly enhanced from the last test, but it isn't anything highly interactive. Up to 9 people can connect simultaneously. We didn't get more than 2 or 3 simultaneous connections last time, so I'm probably overly optimistic. Some of you noted from last time that there is no character echoing or line editing. Telnet users on Unix machines will probably have local line editing, which makes things a wee bit nicer. The standard Windows telnet client doesn't do that by default, so you will type but not see your characters. That's a project for a different day. Here is a picture of the machine you are connecting to, complete with the Western Digital 8003 Ethernet card grafted onto the side: http://brutman.com/PCjr_WD_small.jpg And lastly, if you remember, type in your OS and machine type as a command. It will complain about it being an invalid command, but I'll see it in the log and I'll have a better idea of what I'm testing against. Thanks in advance, Mike

MITS Altair 680 KCACR Cassette BASIC Recovered

by grant＠stockly.com

I thought I would post this for the search engines to latch a hold onto. It appears that my 20k post including the Cassette Basic source was killed. If you want the authentic S record listing of MITS Altair 680 KCACR Basic then send me an e-mail... If you mentioned that you wanted it, please e-mail me off list again. I may forget! I am in the process of setting up a web page on the 680, so I'll put the information there when I'm ready. If someone is interested in helping me "figure out" what is on the leader and footer of the tape, please request the original files. I have two. One 8bit ASCII and another forced to 7bit. This one attached has been forced to 7bit ASCII. Both files WILL load into the Altair without issue. It seems random which bytes had the 8th bit set and which didn't. Also, there is what appears to be garbage after the S0 record. I have no idea why. The tape has a bunch of 7Fs, then S0 and a bunch of garbage, and then 00s. At the end there is some garbage too. The KCACR ROM appears to ignore it. I've found this file reliably loads at 9600bps. It takes 21 seconds to load into a 680. .J 0000 MEMORY SIZE? TERMINAL WIDTH? 80 WANT SIN-COS-TAN-ATN?

MITS Altair 680 KCACR Cassette BASIC Recovered

I thought I would post this for the search engines to latch a hold onto. I thought a second about posting a 20k e-mail, but the posts from the past hour FAR exceed that. ; ) If someone is interested in helping me "figure out" what is on the leader and footer of the tape, please request the original files. I have two. One 8bit ASCII and another forced to 7bit. This one attached has been forced to 7bit ASCII. Both files WILL load into the Altair without issue. It seems random which bytes had the 8th bit set and which didn't. Also, there is what appears to be garbage after the S0 record. I have no idea why.

It takes 21 seconds to load into a 680. The listing below is unmodified from an original Altair 680 tape. The garbage leader and footer have been removed. .J 0000 MEMORY SIZE?

My first Mac

by cclist＠sydex.com

Yeah, no kidding--someone game me a Mac 6100/60. Not very exciting, but I've upgraded the memory to 40 MB and added a 4GB hard disk from parts in my hellbox. So, does anyone have any first-hand experience with Linux on one of these critters? Is it worth the installation trouble? Cheers, Chuck

Recovering Cassette Tape Records

by lee＠geekdot.com

After a bit of a ponder this should be about as fast as you can get without putting multiple statements on one line .. 1 GOTO 5 2 WAIT A,D,D 3 POKE B, PEEK(C) 4 GOTO 2 5 A=61456 6 B=61441 7 C=61457 8 D=1 9 GOTO 2 .. if multiple statements per line are allowed then this should be faster .. 1 A=61456:B=61441:C=61457:D=1 2 WAIT A,D,D:POKE B,PEEK(C):GOTO 2 Lee.

My first Mac

by compoobah＠valleyimplants.com

>> Does it pop up saying the disk needs to be initialized? Are you sure >> it's >> HFS? I'd first give Disk First Aid or some similar program a go at it. Start up DFA first and then insert the disk and scan it. Try covering the HD hole, also- 800k Macs could format 1.44s at 800k which could confuse a newer machine. You might be sunk, though, if that's the case, as some 800k drives don't magnetize the disk strongly enough and it is unreadable after several years.

any interest in a teal SGI Indigo 2?

by chrism3667＠yahoo.com

I have at least a couple I need to get rid of. Too much stuff. No keyboards or mice (they take the regular ps/2 type though), no OS, probably busted drive door hinges, somewhat scuffed up. They weigh about 40 lbs, so keep that in mind. Free otherwise. E-mail me offlist please. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Recovering Cassette Tape Records

by grant＠stockly.com

I'm pretty confused right now. I wrote a small basic program to dump my cassettes into the computer. 1 IF (1 AND PEEK(61456)) = 0 THEN POKE 61441, PEEK(61457) 2 GOTO 1 61441 - ACIA DATA PORT 61456 - KCACR STATUS PORT 61457 - KCACR DATA PORT I'm not checking if the ACIA is ready for data, because when reading at 300bps and transmitting at 9600 we should never have to. Why am I getting strange results below? The only thing I can think of is that it is somehow missing every other byte from the KCACR. Does anyone see anything wrong with the basic program? All 500 lines returned are the exact same length and they all start with 13. 1300D603EAFE3A00880C8 13000000000000000000C ... 1310452E25D34F0FEE5CC 1310C71943CF143316541 Missing every other byte? Maybe the 680 and it's basic isn't fast enough for my program? I'm just guessing that S1 and 13 are supposed to be there... S113_0_0_D_6_0_3_E_A_F_E_3_A_0_0_8_8_0_C_8 On top of all this, I'm having a hard time understanding the format. This is a good line: 1 2 3 4 5 6 7 8 9 10 11 12 13 S1 13 0000 0D 76 00 F3 7E 18 F9 7E 03 3C 00 00 48 38 00 2C 7E S1 means its a data record, 13 is the byte count, 0000 is the address, and 7E is the checksum. So what are the mystery bytes? How do you get 13 data bytes and still have a place for all of the rest? 13 is supposed to include the checksum! The checksum is the one's compliment of the sum of the all bytes except S1 and the checksum itself. FF-(13+0D+76+F3+7E+18+F9+7E+03+3C+48+38+2C)=7E So 7E is the checksum. I want to know where all those bytes go! :( Grant

Shipping company moveit.com

by legalize＠xmission.com

I'm using them for a dovebid sale and while things are scheduled to be delivered tomorrow (knock on wood), so far I've been pretty unimpressed with moveit.com. They haven't been very good at communicating important details like MY SHIPPING ADDRESS, when the shipment would be made, how payment was to take place, etc. They say they do a love of business through dovebid, and while that may be so, I don't think I would use them again in the future compared to my experiences with cratersandfreighters.com. Has anyone else used these guys?

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.

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. I have it connected to my stereo, via coax digital audio out. I only have 4 or 5 caddies laying around though. >As for the OP's question, if _I_ had a 7 *transport* box, I'd consider >replacing most or all of the transports with SCSI DVD-ROMs for a >decent amount of archival storage readback.

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. Anyone (local) want some? Anyone got any ideas what to DO with them? -Tom [Love] Once he drew With one long kiss my whole soul thro' My lips, as sunlight drinketh dew. --Alfred Tennyson (1809-1892) Fatima --... ...-- -.. . -. ----. --.- --.- -... tpeters at nospam.mixcom.com (remove "nospam") N9QQB (amateur radio) "HEY YOU" (loud shouting) WEB ADDRESS http//www.mixweb.com/tpeters 43? 7' 17.2" N by 88? 6' 28.9" W, Elevation 815', Grid Square EN53wc WAN/LAN/Telcom Analyst, Tech Writer, MCP, CCNA, Registered Linux User 385531

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. Watch... -------------------- CSAVE A ?TM ERROR OK CSAVE ?SN ERROR OK AHHHH! ?SN ERROR OK AHHHH! 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
