Yes, I really did. Are Apple IIgses that easy to kill? Normally I just keep a single 5.25" drive attached to it, but I needed a 3.5" drive as well today (I'll explain as part of a larger question). So I plugged the 3.5" into the computer, the 5.25" into the 3.5", turned the machine on, it made three loud pops and died. The power light does not come on now and there is no activity from the disk drives. I fortunately do have another IIgs in stock, and was able to swap power supplies so that it boots again (this second is a defective unit I use for spare items). I will say that I wish every power supply were as easy to replace as the IIgses -- it literally just snaps in and out. Now that I have shot an apparently unrepairable PS, or is it?, what did I do wrong so I don't destroy more hardware in the future? Can you really not mix drives? Remember, I'm a C64 freak and I have all kinds of disk drives connected up to my Commodore farm. :-P Now the larger question. This IIgs netboots ProDOS 16 from an SE/30 over AppleTalk, which works quite well. Soon I'll have the IIgs using the SE/30 as a gateway to the apartment network (and shortly thereafter the C128 will join it). I tried to netboot GS/OS on it -- I don't know what version (this is a ROM 03 1MB IIgs). It gives me the nice "Welcome to the IIGS" screen, an AppleShare CDEV? appears lower-left and then disappears, it chugs along some more, and then drops out and puts me back at the AFP client. It then refuses to boot GS/OS at all until I restart the machine. Is this a symptom of something specific? If I just wanted to check if the machine were capbale and properly configured for running GS/OS, how could I do that? And where can I find GS/OS disk images? I looked in ftp://ftp.apple.com/Apple_Support_Area/Apple_Support_Area/Apple_Software_Up… but there doesn't appear to be anything in there(?). Disk Copy-format would be nice, something I can break apart on my Power Mac.

Not only was this sucker multi-synchronous, but it supported *composite* video as well (worked terriffic with my SEGA Master Sytem game console). Awesome monitor-- it could synch up to just about everything I could throw at it at the time (including a PerSyst BoB-16 video adaptor). Wish I had one today . . .

On topic: VAX graphics board question

by vaxman＠qwest.net

Greetings all, I have a VAXstation 3100/M48 with a rather odd graphics card in it: SCANPROC 8 PLANE 2D Made by digital, same form factor (roughly) as the VS40X, but Ultrix 4.4 doesn't recognize it. VMS 5.? does. Since the goal is to run NetBSD when support for graphics stabilizes (and Ultrix til then), does anyone know what's up with this board? One big LSI logic chip instead of the 10 or so small DEC chips. NOTE: This message cross-posted to classiccmp and port-vax... Please edit your headers (or reply to me personally). Thanks! Clint

Need help with retrieving data from a DOS 2.11 formated floppy disk

by guntis＠cyberstate.infi.net

Depends on the machine it was written in. Many machines back then had 720K floppies, which look like 1.44M floppies except for the 'density' hole. The 'old' machine would write the HD floppy in 720K format. The 'new' machine (NT) would sense the density hole and attempt to read the floppy as a 1.44M. If possible, use a 'real' 720K floppy (one without the density hole) to write the data if the drive in the machine is only 720K. That way the new machine will sense that it is a 720K floppy and read it accordingly. You could just tape over the density hole on a HD floppy - just make sure you format it on the 'old' machine before writing to it. Of course, if the old machine can really use the 1.44M floppy then the above won't help much. :-} AFAIK the floppy format has remained relatively stable. At least through NT4 and WIN9x. Guntis. From: jimmy tsai <jtsai(a)vortek.com> I need help to solve a problem. Could anyone lends a hand? The company I work for has a machine that runs on DOS 2.11 There are some data on that machine that we need to retrieve. The information is transfered from that old machine to a 1.44mb floppy. When we put the floppy into our pentium winNT4 computer , we can not read the information on the floppy. The NT os simply says it does not know what format the files are at. Now do I need to install a dos 2.11 or is there anyway around it ? What is the format the dos2.11 writing its files in? Are there any program that reads in that type of format? Does any one here have DOS 2.11 that I can download? Even if I do have DOS 2.11, will I be able to install it or do I need very old hardware as well?

Seriously OT: Firearms (was RE: Interesting show on the Computer Garage)

by SUPRDAVE＠aol.com

Can we get back ON TOPIC and talk old computers, such as how to coax a dead mac portable to power up? I have one and can get a cracking sound out of the speaker but nothing else. -- DB Young Team OS/2 old computers, hot rod pinto and more at: www.nothingtodo.org

IBM PC parts

by antonio＠ptt.yu

Since you are all proffesionals (the way you talk about things), looking at me, i should be quiet, but i have a serious question (no flames real problem). What is what in 5363? What that 3+4 digits code mean and do anyone know where to find equivalency tables for that. Like 1582582 == 7400 (wild guess). If anyone have a direct address (www) of a solution, feel free to e-mail me directly (i am rarely online, thunder eaten my modem, working partialy with a relay circuit suplement for electronic hook). I have trashed this box because it was defective already. Best Regards to ALL of you, Antonio antonio(a)ptt.yu

Multi-Z80 system design

"Old" doesn't necessarily mean "useless". If you don't plan to use them for anything, I'd suggest distributing them here on the list or perhaps putting them up on eBay. -Dave McGuire
