PowerUser external SCSI HD

PowerUser was the house brand name used by PC/Mac Warehouse. I know they made a line of assorted equipment for the Mac, so I assume they also made stuff for the PC. Most everything was just repackaged items made by others. Based on the name, I would figure it to be a standard external SCSI hard drive. A fairly standard item for the Mac, and quite commonly found in the early Mac days. I might even have a PowerUser SCSI drive kicking around some where (not sure, I had a number of brands, I wasn't very brand loyal, so when I needed a drive, I bought the cheapest... after I got burned on the Jasmine/Rodime fiasco, I stopped worrying about who had the best rated, and just bought on price and price alone) -chris <http://www.mythtech.net>

Typical MP3 recordings at around > 128Kbps end up at around 1MB per minute. Which is why people use MP3s, which are compressed, instead of of uncompressed WAV (which is almost exactly the same as AIFF) :-) If you make an ordinary audio CD (ie to use in a CD player not an MP3 payer) you end up with roughly 10MB/min, or a little over 600MB/hour. -- Pete Peter Turnbull Network Manager University of York

Great finds at Auction Today and at Thrift

by jrkeys＠concentric.net

It was a great day at the auction, I was able to get these items: 1. 3-Nextstation Color's was is missing the harddrive need to get a sound box from the warehouse to test them. 2. 1-Nextstation Turbo powers up but no OS on it. 3. One mono display and one 17' color display, cable for both was in the lot. 4. One Next laser printer. 5. IBM 7208-001 8mm 2.3GB external tape unit ($2.50). 6. Several IBM terminals will have get the numbers next time I'm down to the warehouse. 7. Several computers from different mfg. have not tested any yet. Best find of the day was at a thrift (I only had time to stop at 2 of them) it was a Atari 2-player table console titled Missile Command. It has a coin slot for 50 cent to play the game. You sit at this unit and put your hands into the controller pocket that has a big yellow trackball and three fire buttons for each player. They did not have the key to get into the unit and I have not plugged it in yet to test. It's in great shape and is model number 23601. I checked on google and could not find any information on the unit. Anyone know where I can get spec's on this unit and what it cost new?

RT-11 Memory Issues

by mbg＠TheWorld.com

I can't believe that ADVENTure would eat >up more than 1 megabyte of ram. Is there some tuning bit that I am >missing here? Unless the program has been designed to use extended memory overlays, or specifically designed to use extended memory directives, it is limited to the standard virtual memory address space of 56kb, minus whatever is used by the monitor (and this is carved out of the low 56kb of the machine... the rest of the 1mb is unused). As I already mentioned in another post, you could try using VBGEXE to run it in its own 56kb space.

I found a couple of MP3 files for my Exidy Sorcerer on the web, and they loaded fine at 1200 baud. I suppose the success rate depends on the quality of design of the cassette interface, and the bit rate in the MP3. mpg123 tells me that Galaxians.mp3 is MPEG 2.0 layer III, 16 kbit/s, 22050 Hz mono, it's 520kB long, and "plays" for 1 min 25 secs, including the header. I've heard of other people using MP3 files for BBC micros at 1200 baud too. -- Pete Peter Turnbull Network Manager University of York

Fluke Stuff

by NAVIGATE87＠aol.com

Joe, I use some of them, I had a all or nothing deal so I got them all. The tapes are 18.00 each min order 10. The pod I am looking for is a Z8000 my error. I have a 9100 mainframe also, but It seems to be so software dependent that I haven't figured how to load and save my programs. I need to figure how to hook the 9010 and/or the 9100 to a pc so I can key in my very long programs and save them, or at least load from a PC. I used to use the 9010 but the company policy was not to allow techs to do anything beyond insert tape and run the test. Now I work for a new company and I have to figure how to do all this other stuff oh fun of wearing many hats. Thanks, Don
