The End of Classic Computing, and in fact, the end of Computing as a hobby for almost all of us, is on the table in the U.S. Congress in the form of The Consumer Broadband and Digital Television Promotion Act (CBDTPA). This insidious bill would strike at the very heart of this community, the software that keeps our ClassicComputers running, unless we or someone incorporates anti-pirating measures. Now, if that sounded inflammatory, it should. It's not quite accurate either. The bill will cover only software created from the time of the bill's passage and on into the future. The stuff we play with now would therefore be exempt. There appears to be a loophole for stuff you do that you never distribute. There also appears to be a loophole for computers that do not contain microprocessors. But there would be a horizon coming soon. If the bill is passed, computers and software being developed now, once 10 years old, might be on-topic, but you'd be breaking federal law to share software. Sponsored by someone who must surely be certifiably insane, one Senator Fritz Hollings of South Carolina, if you want more information, see: http://www.wired.com/news/politics/0,1283,51274,00.html This will require lots of work to defeat, I think, as the politicians have bought into the fantasy that a pirated copy of something conctitutes a lost sale.

When I got my 68040 Cube upgrade kit it came with a motherboard and an OD of NeXTstep 2.0, and a NeXT SIMM-puller tool. And some instructions about the sequence in which to change things. All this information is coming out of my occasionally fallible memory. But I'm sure that I was using NS 2.0 and 2.1 long before I had a CD reader. carl

For some of us a soldering iron is an instrument we use to build or repair circuitry. For others, it's an implement of destruction. I'll wager there are plenty of people on this list who have skills you don't possess. That doesn't make them better than you, just different. The one thing we all have in common on this list is the desire to preserve and use old computers, and we all try to use our skills to do what we can to achieve that goal. Do you really thinks it's unreasonable for someone to say "I'm not confident of my soldering skills so I don't want to risk this computer's health by soldering it?" To me, this is a very rational attitude. It sure would be boring if we were all the same . . . ;>) Does any of this make sense to you? Glen 0/0

IBM PS/2 Part wanted for 9577

by fernande＠internet1.net

If I recall correctly, IBM had a special stand for the PS/2 Model 77 so that it would sit on it's side. Does anybody have one they want to get rid of? I have one for a generic PC but it doesn't quite fit the PS/2 correctly. I've almost got my new 9577 reassembled...... been cleaning it :-) Chad Fernandez Michigan, USA

Problems with Ersatz-11 and CDROM

by jhfinepw4z＠compsys.to

I realize that there are probably very few individuals interested in this topic, however here goes. I am running E11 (Ersatz-11) under Windows 98 so that I can run RT-11. It works great in almost all respects and I can even live with this one minor problem. However, perhaps someone might be able to suggest what needs to be fixed. I have just acquired a CD-RW and been successful is making copies of my files to a CD-R and over the past week a few test files to a CD-Erasable. I am using "Nero Burning" as the software which "writes" to the CD and while I am a bit disappointed that the write speed to the erasables is only 2x as opposed to 16x for the WORM media, I can easily live with that and it is not a problem. I have also discovered how to "DUMP" to the screen any of the 2048 byte blocks on the CD - in hex of course. And finally, I discovered how to copy a single file to the CD starting at block zero of the CD media - or at least I have done so with the erasable media and I hope it can be done with the WORM media as well. The only thing I have not found out as yet is how to copy all of the sectors written to a CD back to a file on the hard drive so that more than one copy can be made to more blank CDs. I doubt if that will be a problem - I just have not even bothered as yet to try. When I copy a single file to the CD using Nero and the "File" menu o File o Burn Image o Open o Foreign Image Settings - Block Mode 1 - Block Size (2048 Bytes) - Image Header (0 Bytes) - Image Trailer (0 Bytes) o OK o Ignore - during this test, the Image file is not a multiple of 2048 bytes o Write where each "o" indicates another menu sub-level. Nero does correctly write the file to the CD as far as I can tell - except perhaps for the last few blocks since the size of the image file was not a multiple of 2048 bytes. Using C:foobar.DSK as the Image File I wrote to the CD, then using Nero and "Recorder"/"View Track", I can look at each 2048 byte block the CD to verify that the Image File Foobar.DSK was written to the CD and under E11 I can give the commands: MOUNT DU0: CDROME:/RO MOUNT DU1: C:foobar.DSK/RO Then under RT-11, I can also give the commands DIFFERENCES/BINARY/DEVICE DU0: DU1:/START:64./END:last-block-3 which results in a perfect compare. Under RT-11, I can also do a DUMP/TERM DU1:/ONLY:any block including block numbers between zero and 63. DUMP/TERM DU0:/ONLY:only block numbers 64. or greater. NOW!! Here is my problem and the question. Why can't E11 read blocks zero to 63. on the CD? I can see them under Nero and DUMP these blocks to the monitor under Nero. I could easily modify the MSCP device driver for RT-11 and automatically add 64. to every block number before I try to read it from the CD, but that would really mean a new device driver (CDX.SYS seems like a good name). I would also need to decide if that should be just for partition zero (my preference) or all the 20 or even 21 partitions on the CD. Or perhaps, someone has already discovered the answer why Nero can read those blocks under Windows 98, but E11 can't. By the way, one other solution is to just not use partition zero under RT-11 under E11 under W95/W98. Before I could burn my own CDs, that was the way that Tim Shoppa set up the RT-11 Freeware CD in any case. However, now that I have been able to actually read blocks zero through 63. from the CD under Nero, it seems too soon to give up on E11. I suspect that a partial answer may be that Nero uses W95/W98 operating system calls that are not used by E11 which is essentially a DOS program. If true, that obstacle might be overcome if the modification to E11 is simple enough. PLEASE!!! Can anyone suggest what the difficulty might be?
