Cray Y-MP & Convex for auction in UK

by mark_k＠iname.com

Hi, In case anyone is interested (and has loads of space and a large truck), apparently Cray Y-MP-EL and Convex mainframe computers are part of an auction to be held on 8th December near Honiton, Devon, England. The URL of the auctioneers is http://www.saqnet.co.uk/users/mstcommercial If anyone decides to go to this, please let me know (I may want to scrounge a lift off you...). -- Mark

That's what I understand it consists of. A very high speed turbo-loading routine is used; tapes would have trouble coping with this. The first track is probably a normal-speed file containing the loader code, and the other tracks would be the games recorded at high speed. (Can anyone confirm this?) I have many old computer cassettes, and have been thinking of recording them onto a computer in order to preserve their contents. The signal from computer tapes oscillates between two levels, right? This being the case, it should be possible to record them using 1-bit sampling. Perhaps record with 8- or 16-bit sampling and then convert down to single bit. Are there any programs to do this conversion? I imagine the equivalent of a Schmitt trigger (in software) would work. What about playing back a 1-bit audio signal? Are there any standard audio file formats that can be used to store 1-bit data? The final 1-bit audio files should be highly compressible, so they could be archived with zip etc. to reduce size. If sampling at 44.1kHz, the uncompressed 1-bit sample would use about 5.4K per second. For a five-minute tape, that comes to under 1.7MB. Sampling is of course the best way to preserve software, rather than converting the files themselves; with a sample an exact duplicate of the original cassette can be created, and things like copy-protection and turbo loaders are no problem. Actually recording tapes to audio CDs is quite wasteful since you can only get 70 minutes or so on a CD (an issue if you have hundreds of cassettes). My approach would be to archive tapes as described above; of course burning an audio CD is useful for transferring the data back to the source computer. -- Mark

MacDraw (?) and other software wanted

by roblwill＠usaor.net

Hi! I have a Mac Portable with 4 MB RAM, 2400 modem, 40MB HDD, running System 7.01 Pro. Does anyone have any drawing software that"ll run on it that they'd be willing to send me? I'm also looking for a small web browser and TCP/IP dialer program for it. Are there any MIDI players for the Mac (like a Windows MediaPlayer)? What format are the sounds on a Mac, where do I get them (the Portable has no input, so I can't record anything), and how do I play them ? If there is an audio player for MacOS, where do I find one? I also have a few questions: - Just how rare are the models with the factory-installed backlight? I've heard that they're fairly rare, and the non-backlit versions are much more common. -Is there any possible way to fit a bigger HD into it? I've been told that the HD is a special type, and other ones won't work. ThAnX, -- -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1> PS>> Please ignore the fact that some of these questions may be pretty basic, but the Portable is the first Apple I've had since a //c.

Call for final Elf99 design input

by allisonp＠world.std.com

< Options under consideration: < < o Sockets for two 1822/2101 256x4 SRAMs, the same style used by < the original Elf. < one 2116 outweighs that. <o A 1851 programmable input/output port -or- a pair of 4508 latches Use the one that is available. < wired as one input and one output port (as in the COSMAC VIP) Handy and useful, do the ports. < o A 1854 UART Desirable. < o A protoyping area of .1" spaced plated-through holes, nominally < a few inches long by one or two inches wide. < < o Either a dual 4042 address latch or a single 4508 latch. One or < the other is needed to implement more than 256 bytes of memory. < This would be optional in a machine built with dual-256x4 SRAMs. Consider 74hct373. < o A pre-programmed 27256 with a "library" of simple programs < (Accessible by enabling the ROM switch, setting the program < number in the switch register, then setting the control switches < to "run"). Good idea! I have sources for minimonitor and UT4(RCA) plus a buch of others in hex from articles. < Did I miss anything? Any other suggestions?

The one I found recently has an 8088 and 256K RAM, so I presume it was intended let an Atari run MSDOS. It looks like it dates from around 1984. Can you comment a bit more on the history of these ATR second processor cards and do you happen to know how many different types they eventually made? Arlen Michaels amichael(a)nortel.ca
