Hi gang. Well, my father is safely transitioned to his iMac, so as soon as I get done sorting stuff out, I'll have an apple2GS with 4 megs of ram and a printer card, along with a monitor, 2 3.5 inch drives, and a 5.25 inch drive to sell. In a related note, I got my 2e running with a hard disk. It boots to Prodos so fast it doesn't bear mentioning... but it's been a long time since I used an 8 bit apple2, how do you transition from one .SYS image to another? I have a launcher that does the job on my GS in 2e mode, but my e doesn't appear to have enough ram to run it. -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- Vote Meadocrat!

3-phase (was: Re: CDC 9766 Drive and packs)

We pay 12 cents a KWH in this part of Oz. Most people with serious heating needs opt for natural gas. Mind you, we don't need heat as much anyway, but an airconditioner of reasonable size can cost upwards of 20c an hour to run, and in summer (like now) we need it. Might have to emigrate....:^) 3 phase is uncommon outside industrial sites. ETSA (Electricity Trust of South Australia) will only install it if you can prove you need it. 415v 3 phase, that is. Some (all electric) homes may have a couple of seperate 240vac single phase circuits that are fed from seperate phases, but even that's unusual.

What is this? HP internet antenna

by rigdonj＠intellistar.net

A friend of mine found this at a garage sale. Small grey box with a long cord and DB-9 connector. The front of the box says "Air Media Live" and has a LED on it. Does anyone know what it is? Joe

RT-11: ?DIR-F-Invalid directory

by mbg＠world.std.com

>Second to the last command: IND SYSGEN >Last command: told it to build only the monitors Then I would say that it may depend on what you specified for the output files for the sysgen. You see, it is possible for just about any command issued under RT to specify a disk without a filename... in which case the output of whatever command you have issued will be to the *disk*, beginning with block 0... this means that depending on how many blocks are written, you may wipe out the boot block (0), home block (1), secondary boot blocks (2-5), directory (6-67) and files (beginning with block 68). >It made it through the first bit of assembling (pardon the description, >I'm still learning) and then it bombed. I tried to start it again and it >bombed immediatly. At which point I decided to type: BOOT DU2: Again, I'd need to see the *exact* commands issued to know how bad it might be... >The worst part is that I'd noticed that FLX under RSX11M couldn't write >to the drive the night before. I guess I should have backed up my data >at that point. Hmmm... then sysgen and what it was doing may not be the problem. What is the disk you are using? If an MSCP disk (like an RD series disk), one or more blocks may have the 'forced error' bit set... which results in errors when you attempt to read it. The way to clear this error is to write the block (which I believe results in a revectoring process for the bad block). The data for that block may be lost, however... I seem to remember the option '/K' for DUP... I'll have to check the documentation. One thing which may be a problem is that if the bad block is in the 'system area', blocks 0-68, then RT pretty much refuses to allow you to do anything with the disk... the idea being that there are times when not enough of a device driver is in memory to do bad-block revectoring... >I guess I should look at it this way, even if I can't recover the data, I >think I've got printouts of most of it.

Unix for 8080/Z80? [Re: WooHoo!! PC/XT Unix anyone?]

by joe＠barrera.org

>Actually, there was a thingy called PC/IX which ran on those non >memory-managed systems. I actually managed to snag a copy a few years ago. Well, and of course there's Minix (where Linux started)... Any Unix clones for 8080/Z80 systems? It ought to be doable, given that the original Unix was done on a 64KB address space machine... - Joe

Displaywriter system generally consisted of the following boxes: System unit. PC-sized, half the case == power supply, other half == card cage. Card cage contains system board with 8088 and other cards. Keyboard. The thing you've got Monitor. Very similar to IBM original (mono) PC monitor, I think Printer. Daisywheel, EBCDIC, current loop. Disk drives. Usually a dual 8" unit. Could be SSSD or DSDD iirc. > At present it would seem to be about to join the 3270 monitor I have (can't > remember the model #) as interesting but unusable. > Or could I get gadzillion bucks for it on e-pay ? Any info ? My advice is: keep it against such time someone needs it... Philip.

web archive

by lwalker＠mail.interlog.com

Hi Kevan. I hope you do not kill your archive.It is a thankless task and you deserve kudos for undertaking it. I for one appreciate your efforts greatly, and the alternative would result in increased mail as questions answered in earlier threads were reposted. I also would have to get a bigger hard drive for keepable posts which are numerous on this list. I don't think I have ever received spam related to this mail-list. I did get some mined from the CoCo list and classicmac list I believe but I unsubscribed to those a whle ago for other reasons. Spam is a fact of life for anyone using the net. I use an altered address for newsgroups however, which cut down considerably on the spam I was receiving, but I still get some via other activities. I suspect even Yahoo or Delphi lists etc., are not secure. Surely those who object to archiving could use an altered address. Aren't there also means such as deja news' "no archive" to achieve this ? ciao larry lwalker(a)interlog.com

Atari 1050 mods?

by red＠bears.org

Hi there. I finally scored a piece of disk-based software for Atari 8-bits, so I decided today to test out my atari disk drives to see if any of them actually worked. One 1050 did. The other 1050 doesn't run the seek test when you turn it on, and is invisible to the computer. I removed the actual disk drive from the cabinet and verified that it does in fact work in the other 1050 chassis. While doing this I noticed that the non-working 1050 seemed to have had a modification done (rather sloppily, I might add; I suspect this has something to do with why it doesn't work properly). There is a hand-written silver sticker over what I'm assuming is an EPROM that reads, "Doubler". There is a second Motorola 6810 piggybacked onto the normal 6810, and a couple of jumper wires leading off into the PCB. What was this, and how was it done properly (so I can verify that it's ok)? I have a Percom branded full height disk with Atari SIO connects on that also seems to not work. I think this is because I need to decipher the 4-position DIP switch at the back panel. Any hints? As it is now, the access light repeatedly switches on and goes off again, each accompanied by a moderately loud click. The light is on for a second and then off for maybe two. It doesn't ever stop doing this, and the drive is invisble to the computer. The drive inside is full height, and made by Tandon I believe. ok r.
