Old Radios - computers

by Innfogra＠aol.com

Hey, I like old radios too. I got my start with tube short-wave radios about the time the transistor was invented. I took a Hallicrafter S-40B to 4-H summer camp and strung a long wire antenna. I still travel with a short-wave, a Sony ICF2002 and a wire antenna. However this is a classic computer forum so I will ask computer questions. Is there a web site or inventory of early Russian computers like the Russian Calculator site run by our fellow friend AD? Was there a system similar to SAGE? (I loved Jim Willings pictures.) What is the history of the early Russian computer development like? I also liked the report back to the list of contact with the posters. If anyone ends up doing business with them I would love to see that also. Paxton

Price, or something. The 8086 was the same thing as an 8088, but with a <full 16-bit bus, which was important for almost everything in those days <(IE before you had an on-chip cache for frequently used operations, an on <chip FPU for 3D/math, and all kinds of stuff like that.) The 808x series has what was fairly new then a prefetch cache though of very limited size. Caches on chip grew in use when the fab technology could cram enough on a die to permit a larger one.

AC/DC radio precautions, was Old Radios

I stand corrected. This is a good time to mention to our list members that if they find an old tube radio, especially an AC/DC set (you can tell this by the absence of a power transformer and a tube complement which will equal 120 volts for total filament voltage, some even have line cord resistors), THESE SETS ARE EXTREMELY DANGEROUS AND LETHAL, often having the 120 hot wire soldered to the chassis.

AC/DC radio precautions, was Old Radios

by Marty＠itgonline.com

Chris is quite right. Sorry, the light bulb rig was a bad idea (I have never used it but it was mentioned to me once upon a time) and I agree the isolation transformer is definitely the ONLY way to go. Regarding trusting a spec sheet or schematic, I wouldn't. Many sets I've come across have been modified, often in unconventional ways.

If you need to work on one of these sets, use an isolation These points are valid . . . > transformer or wire a light bulb between the set and house current > (the light bulb filiment should open before you fry, thus breaking the > circuit). Hold on there! An isolation transformer is the *only* way to go to provide isolation from the line for a transformerless radio or TV. The light bulb will NOT open (like a fuse, as the above statement infers) but will simply pass current up to at least the wattage rating of the filament. (100W bulb = approx 0.9 Amperes @ 115V.) A few microamperes could be enough to kill a person under many conditions at this voltage. The concern for inexperienced folks handling a bare chassis of a transformerless set is nonetheless well placed and the part about the chassis being hot (115VAC in North Amer. or 230VAC in most of the other parts of Earth) is particularly important to be aware of. A chassis could be hot even if the line cord is correctly plugged into the wall receptacle. This is because a commonly used signal bypass capacitor from the hot side to chassis often is quite leaky (simply, it has relatively low DC resistance) or even shorted from age. I've been hit too many times while handling these sets over the past 33 or 34 years. As with any of us troubleshooting computer power supplies while the power is on, *always* stuff one hand into your pocket while probing around in the circuit. Enough of this off topic radio stuff --although I had to post this to correct a seriously incorrect piece of advice given above. On topic part could be to note that using an isolation transformer while poking around in a computer's switching power supply could make accidentally touching a few parts in the line-side of the PSU somewhat safer. Just being careful and focusing on where one's hands are at absolutely all times is the safer way to go while having to work on live high voltage circuits.

Even with a short circuit, it will only light at full brillance, not act as a breaker. It may protect components in the radio, but it is no shock protection. A 40 watt bulb (a smaller size) still has about 0.3A at 120 volts, way more than enough to electrocute yourself if the current flows in the wrong path :(. -Dave

Its done in java, and will even run in your browser window. The site even has a list of games that you can just click on, download into a window, and it runs the game in the java emulator. Slick! Even on the slow setting most of the games run 2-3 times as fast as the original machine, so unfortunately its too fast...but on a p233mmx, thats damn impressive fast java code....especially running in a netscape browser! -- ============================================================--------- Dominique Cormann Email:kozmik@wave.home.com dcormann(a)uoguelph.ca Homepage:http://members.home.net/kozmik

If Intel's 8088 was stripped of half it's bus width, why was it used so much more than the 8086? One of the few computers that I've seen with an 8086 is the WANG WLTC (in the SCSI drive string). With being only 4 MHz (I think), it way out-performs my 8088 8MHz Zenith (I just wish it wasn't so dang big). I remember someone on here saying that an 8086 and 8088 were interchangeable.

Yet another source lost to the dark side...

by jimw＠agora.rdrop.com

Well, yet another unwelcome discovery on eBay. For some time its been known that there was a person in the Albuquerque area (think he was a former MITS employee) that had some quantity of parts and some MITS equipment. Well, the parts business must not have gone well because it appears that he is dropping most of his stock on eBay as a series of auctions. Mostly bare boards at the moment. Business must be good... He did not even reply to an offer I made on a board almost a month ago... Grab what you see as soon as you see it... Or it will show up in an auction tomorrow! -jim --- jimw(a)agora.rdrop.com The Computer Garage - http://www.rdrop.com/~jimw Computer Garage Fax - (503) 646-0174

O.K. I just tried that. It doesn't work. However, when I close all the switches (on), and set it as drive 1 (straight cable), FDISK says it can't find disk 1. It does the same with a twisted cable (says the drive is disk 2) Should I try setting it as disk 2 and see what happens?

It probably depends on the system config. I have hardly any problems with IE, and have about every problem thinkable with Netscrape, but my dad's computer, which is slower, has a smaller HD, and less RAM, is just the opposite.

Seagate ST-506 DIP switch settings needed

by roblwill＠usaor.net

Anyone have the DIP settings for a Seagate ST-506 (full-height 5.25", 5 MB) HD? I can't seem to find it on Seagate's website (or am I just looking in the wrong place?) I'm trying to set it up as HD [0] on an IBM PC using a Western Digital XT-GEN controller. The HD appears to be recognized by the controller BIOS to do a LLF, but isn't recognized by MS-DOS FDISK (5.0 - I don't have anything smaller on 5.25" disks). It just says "error reading Hard Disk". I can only think of two things :wrong jumper settings, or wrong interleave setting. When I LLF'ed it, I left it at <3>, which is what was the ?default? was set at. Or is the WD-XT-GEN too new of a controller for the ST-506 (controller is dated 1987). One last thing: Does anyone have a 360k image (or TeleDisk Image) of IBM PC-DOS 3.0 or earlier (If you need a copy of TeleDisk, email me, and I can email you a copy).

It seems pretty common. There should be dip switches on the LA75 somewhere to let you change the baud rate. IIRC, if you hold down the LF key when you power up the printer, it should print a test page, which I think includes the serial port status. (It's either LF or FF, not sure which) I don't have a DEC printer on my Microvax II, it's an old CITOH 2500, I just told VMS it was an LA210 and it works perfectly. A Brother M1724L also works very well that way too. (Both are 24pin Wide Carriage) The situation may be somewhat different on a PDP with a different O/S of course, I don't know enough about those machines to comment intelligently. Hope this helps.

Does anyone know what >are the proper settings for having a LA75 connected to the VT420?

It will then print the full setup and leave you in setup mode. You can then change parameters by stepping through them with the front panel buttons. Note: the writing that is below the buttons is for setup mode. First get to the parameter you want to change "feature" mode using previous or next then hit "value" to toggle what you want with previous and/or next. Then hit feature to get back to feature mode. Once you have everything set as you want hit setup and it will save and exit to normal. There are 2 protocols DEC and other. Other is IBM proprinter. This is very useful for people that only have inkjets - hook one up to a serial port and use it for routine printing. I have several friends that have bought them from me for just that use. $4.50 for a ribbon at Office Depot is a lot cheaper than inkjet cartridges. Once you have the printer setup as you want it F3 for setup on the VT420. Go to the printer menu and set your baud rate etc. Normal print mode is hit F2 for screen print. Auto print mode is it prints everything that comes to the terminal. Controller mode: The host can send to the printer without displaying on the screen.

One of the few computers that I've seen with an 8086 i it was half the bits on the bus but the actual data rates were very close to each other. The 8088 would go out and do two hits for every one 8086 on the bus but both executed the same instruction in the same number of internal cycles. So for half the bus width you needed less support parts and lower cost for only 20% performance hit. The PC was slow not becuase of the 8088 though... it was the 4.77MHz clock when 8MHz parts were available. that choice was also related to the cost (slow parts are cheaper than fast parts). The 8086 and 8088 are the same CPU save for different bus width. They are not socket interchangeable. Allison

The 386sx is a lower pin count 386 that uses a 16 bit bus insted of the 32bit again for lower cost and lower power. Bus bandwith was not half as it is faster than that. Celeron, PII with big internal cache. I just powered up a celeron 333mhz with 128k internal cache and it's remarkably fast(and cheap). 286 never saw a 288 version. ISA and EISA bus machines are slow as the BUS speeds are limited to ~8mhz. This is where many older machines hit the speed wall. PCI and other extended busses are faster (to the limits of the cpu level bus). Allison

Reverse video on laptop

by Watzman＠ibm.net

It's fairly easy to reverse the video on a CGA computer (laptop or otherwise). All that you have to do is write a different attribute byte to every character of the display once. This will reverse the display and, generally (in terms of DOS character programs) it will remain reversed unless another program writes directly to video memory. I wrote a program to do this, and I probably still have it. If you will E-Mail me directly, I will send it to you if I can find it. You can run it in autoexec.bat, or manually, either one.

It's a Brother EP-41-45 thermal typewriter printer just stuck into the case. Does anyone know what speed the modems in those things were? Mine's loaded with the 1MB RAM option, and modem, but have no idea if it's actually useful or not. One other question: How do I access the RAM above 640k? Do I need a special driver, or does it somehow have 1MB base RAM (Is that even possible??) -- -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1>?

I have never seen a 3 1/2" floppy for it so I am not surprised that it had only a 720 available. I don't think they made a 1.44. I had a MO drive for them once and I know there was a CD also. You could chain more than one hard drive too. Wang had pretty good firmware, so I am not too surprised that they are plug and play. I have no idea how well Wang complied with the SCSI standards.

SCSI floppy controllers

I can't speak for the GS, having never used one, but one of the things I did with Digital's SCSI floppy controller while debugging the firmware was to hook it to an Amiga and have the Amiga use it as a hard disk....
