Bulk Tape Eraser: Revisited

>You have, the degauss coil built into the set.

Mine either doesn't have it, or it doesn't work (I tried the on/off thing many times in the past, never seems to help) It is a Sharp commercial quality TV. I got it from Disney Property Control when working there. Paid $25 bucks for it. It was pulled from the Walt Disney World Dolphin AV Department. The front panel that flips up to cover the buttons is missing, and there is some asthetic damage to the bezel, and the screen draws a little low, so you can see the synch line across the top... but other than that, it is a VERY nice TV for $25 (stereo, has S-Video inputs, and its a flat tube so in my opinion, the colors are a bit nicer and glare is reduced). So maybe the degauss is also broken, or maybe I just have to unplug it rather than switch it off. When you turn it off, and leave it in Line mode, and have an audio feed to the Line such as from a VCR, you can hear the audio real silently coming thru it, so there is a good chance the on/off button only does a standby mode. (The audio leak is also REAL fun when guests stay the night, I leave it in a state where it will leak sound, and then tell people before they go to sleep that I sometimes have ghost problems, but not to worry they are harmless ghosts.... then I get a great laugh in the morning when they are all freaked out because they heard whispering voices all night long) -chris <http://www.mythtech.net>

Bulk Tape Eraser: Revisited

by mythtech＠mac.com

Thinking about my Bulk Tape Eraser... and all the use of the word gauss in the replies... can I use the thing to degauss my TV set at home? It has a nasty purple zone on one side, and yellow on the other (large speakers have sat too close to the TV for the last 3 years... I recently rearranged furniture so the speakers are away from it now). Can I use something as small as the tape eraser on a 25 inch screen? or do I really have to buy a CRT degaussing ring. Just trying to save myself the $35 for a ring if I have something that will do the job sitting here already. -chris <http://www.mythtech.net>

Can anyone identify this board for a Heath H-89?

by Gary.Messick＠itt.com

Re: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2034559690 (Ebay auction of Heath H-89) If you look at the last picture in the listing, it show a board that is mounted on top of the CRT. The same picture clearly shows the mounting screws for both the terminal board + the CPU board, so this has to be some sort of an aftermarket board. My thinking is it is some third-party graphics board. I just wonder if anyone else has any ideas about this.

PO/S disk images anywhere?

by erd_6502＠yahoo.com

I thought I'd run across P/OS RX50 images on an ftp site somewhere recently, but I cannot find them now. I am attempting to save myself a _lot_ of work - the other night, I discovered that the shelf of grey boxes marked "Professional..." on my shelves contain several sets of PO/S distribution floppies - one each of most, if not all, the versions. Since I've recently set up a box with a 5.25" floppy and PUTR, I was thinking of archiving them, but if it's already been done, no need to to it twice. I did re-locate my Ultrix-32M 1.1 diskettes last night... they are on the stack. I have MicroVMS 4.0 done, can't find any of MicroVMS 4.1 and am missing one box of MicroVMS 4.2, but have MicroVMS 4.4 through 4.7, seemingly complete. So... the specific question at hand - are there available PO/S floppy images, or should I run several pounds of media through my drive? -ethan __________________________________________________ Do You Yahoo!?

Yes, but I've seen customers open up the box if Windows doesn't work the way they expect ;>) Coupla examples of customer repairs and "upgrades": Proprietary Mitsumi CD-ROM drive plugged into IDE port on a sound card (burnt board). Hard drive or CD-ROM drive attached to motherboard by floppy drive cable. IDE cables spliced together so the system can accommodate more than four IDE devices. PCI device edge-connector forced into an ISA slot (burnt pcb on device and motherboard). Sound card attached to case properly, but toward the outside edge of the motherboard (where there was no slot of any kind -- sound card's edge connector was hanging in the air above the MB). > I would probably be frustrated myself if customers tried to return items > they destroyed.

If someone seems capable of installing a device AND DRIVERS, I tell them to break the seal, and I also tell them that if they screw something up that there might be a repair bill. For the general public, though, it's "break the seal and lose your warranty." Fair enough? Glen 0/0 If I am not for myself, then who will be for me? And if not now, when? -- Pirkei Avot

Can anyone identify this board for a Heath H-89?

by Gary.Messick＠itt.com

Dwight, The connector blanks shown in the picture are factory standard of the later models, and they included a BLANK for 488. I agree, I don't think Heath ever made a card to implement it, buy my '89 has the 488 blank on it also. The only IO positions populated would indicate a 3-port Serial, and an extern floppy I/F of some sort (they supported 8" and Hard and Soft 5 1/4" of various densities. I remember seeing third party adds (in the day) for add-on graphics capabilities, but don't really remember how they were installed. ISTR that they were replacement boards for the terminal board, but I could be wrong. The reason I asked was, as a kid, I drooled over the ability to do pixel graphics on a CP/M machine. I wonder if this would be a cheap way to pick on up? Probably 0 documentation on it. Maybe I'll email him.... Gary > From: Dwight K.
