I have a NeXT Color Printer that I need to get rid of. Appears to have never have been used, as there is no trace of ink in the lines that is present once the printer has initially had ink installed. Good shape overall. I have no ink for this printer, but I believe compatible inks may be available. Also includes the manual and paper bale. Will let go for the cost of shipping (USPS) from 33327 (FT. Lauderdale, FL). Will also trade for a working Apple Profile. LMK, Jeff

Richard, I can tell you from direct experience that there are lots of PBs and Compaqs out there which the "factory restore disks" won't work on. Also, those restore disks are usually full of crap software which will chew up half the HD with garbage nobody wants.

You can then at least locate the real manufacturer at the FCC site or driverguide.com. Win9x has built-in drivers for the basic video functions but does not have the code for the TV stuff; once again, driverguide.com will probably help. Also, you've probably got an Aztech sound/modem combo in there. I have drivers for most of these so shoot me the FCC ID and I'll email you the drivers.

Anyone Care About RT-11

by jhfinepw4z＠compsys.to

In regard to the Freeware CDs for RSX-11 and RT-11 If you are not receiving this paragraph as part of an individual message, then you are not on my list of individuals who may wish to receive their own copies of the CDs. In that case, please reply so that you can be placed on my list when I send out an e-mail with my address. At that time, unless otherwise requested, I will send out a single e-mail to all of the individuals who have expressed an interest - so that you will all know who each other are and have e-mail addresses with which to correspond to each other. Currently, there are 12 individuals on the list in addition to Tim Shoppa. This individual reply will probably be the last before I send you my address so you can send the funds for as many of the 3 CDs that you wish to have. The only thing left is to try and obtain a file which contains the image of the label on the CD. Some of you have received these CDs from Tim Shoppa and for accuracy, I would like to duplicate the actual label that Tim used. If anyone who already has a copy of any of the 3 CDs could help by providing a file that can be sent to a laser printer to produce the labels, that would be appreciated. If I have not received a positive response within a few weeks, then if someone who already has the RSX-11 CDs can at least provide me with the words on both the ".iso" and the "ods1" CDs, that would be second best. I already have the words to be used with the RT-11 CD. I have now finished the verification tasks that I feel are needed to ensure that I am producing correct images. I will be making some copies of the CD images from: ftp://ftp.trailing-edge.com/pub/cd-images/ http://www.classiccmp.org/PDP-11/ http://www.classiccmp.org/PDP-11/RT-11/ http://www.classiccmp.org/PDP-11/RSX-11/ that I have downloaded and wish to offload from my hard disk drive. I have verified each of the 2 RSX-11 and the 1 RT-11 images against the MD5 values in the file MD5SUMS and they are the same. After I copied the images on my hard drive to the CD, I verified them against their respective images in their hard drive files. To do so, I used RT-11 and BINCOM (with some of my own modifications which allows me to also verify block 65535 at the end of each RT-11 partition). Since there are a maximum of 20 RT-11 partitions on each CD and each BINCOM run takes me less than 30 seconds, the whole comparison can be done in less than 10 minutes - which is about the length of time it takes to make the CD copy in the first place. Since there might be a number of individuals who can't download at a reasonable speed (even with DSL it takes about 3 hours each at about 30 KBytes per second as compared with about 3 KBytes per second on a dial up line), I am prepared to make additional copies (Tim Shoppa no longer seems to have the time to do so) and make them available at my cost (for media, label, envelope and shipping carton plus postage to the US) and make them available at my cost of about $ 5 / $ 8 / $ 10 for 1 / 2 / 3 CDs. If you prefer to have me use Maxell Black brand CDs which I have been told last about twice as long, the cost will be $ 1 more per CD. Note that all the prices are in US dollars for destinations in the US and postage from Canada. If you are in a different country, the postage will be different. I have yet to verify these prices to be sure that they cover my costs, in particular the postage after the CD is ready to be mailed, but I am 99% sure they should be adequate. Note that the images at Tim's site are ".bz2" files while the images at classiccmp are ".gz" images. For myself (Windows 98 and Netscape 4.78) DOES NOT WORK with the ".gz" images (since the file is automatically expanded - and the result is incorrect), but Carlos Murillo sent me a Windows 98 version of wget which does work, I suppose on any file. By the way, I tried to hold the SHIFT key down while I was clicking my way through the download procedures of the ".gz" files under Netscape and that did not help. Note that the images at the classiccmp site are ".gz" files, so they are slightly larger. Since I did my original download >from the full size images, I did not initially have a problem with expanding. However, after I successfully downloaded the ".gz" files with wget, I used WinZip under Windows 98. After I downloaded the ".bz2" files, I used bzip2 to expand them under Windows 98. Both expanded files were identical to the full size image, so obviously all three produced the correct MD5 value. If you need help and are running Windows 98 or a compatible OS, I can send you copies of both "bzip2.exe" and "MD5.exe", but not for others OSs. For other OSs (and Windows 98) for bzip2 programs, see: http://sources.redhat.com/bzip2/ and click on either: PC, Windows 95/98/ME/NT/2000/XP PC, Windows 95/98/NT/2000. for bzip2.exe - I was advised to use the second older version and did - it worked fine under Windows 98. For MD5 programs, see either: ftp://ftp.cerias.purdue.edu/pub/tools/unix/crypto/md5/ http://www.fourmilab.ch/md5/ I obtained my MD5 programs at the first site. By the way, for myself, I would VERY much appreciate being in touch with all individuals who have a copy of the RT-11 Freeware CD V2.0 so that we might exchange information about RT-11. Tim Shoppa felt that he might be violating privacy concerns if he made the names, of those who ordered the CD, available. I don't see it that way, so if you want your name to be known along with the other individuals (or not as the case may be - i.e. restrict that you have a copy of the RT-11 CD to ONLY specified individuals such as possibly just myself) so that you can receive interesting information about new developments in RT-11 and the status of the operating system, then PLEASE contact me so that we can share information. Also state if you want to be known to the entire group of just to specified individuals such as myself. PLUS, as for TSX-PLUS, I am going to try again to knock at the door of S&H to see what they may consider for hobby users. Some of you have already expressed an interest in the CDs. I hope that I have sent a personal copy of this post. If I somehow missed you, please send me your request again. For those users who receive a personal copy of this e-mail, you are already on my list. I will send you a mailing address when I am ready to burn the CDs. Please reply if you are still interested. Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.

Weird RAM

by aw288＠osfn.org

The other weirdness to pass my eye (but managed to get) is a small package of chips. These are "purple" DIPs, 16 or 18 pins (can't recall offhand), with two LCCCs piggybacked. This method of construction is common in very high end memory chips and military assemblies. The LCCCs are Mosteks, and some are clearly labelled MK4116 with 1980-ish datecodes. Memory, probably, the good 'ol 16K DRAM. But the weirdness...two DRAMs on a package is pretty weird (I suppose making a 32Kx 1 or 16K x 2), but these things have Apple logos. Huh?

Insanity

by classiccmp＠mail.vintage-computer.com

I was just monitoring this auction: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2032858555 For those who don't want to follow the link, it is a MITS Altair 8080 CPU board, rev 0, that sold for a whopping $787.77. The last one I saw sold for a bit over $250 and I thought THAT was insane. I was considering it as a spare. . . but not at 1/10th of that price. Stories of eBay's demise are greatly exaggerated!

Poly-88 tapes

by dwightk.elvey＠amd.com

Hi All I have been recovering data from some old Poly-88 tapes. I've recovered the following: 1.Poly Tape based BASIC ( I also have a manual for this ) Programs for this BASIC 2. LANDER 3. STOCK 4. REVERSE 5. HAMURABI 6. CASHFLOW 7. A version of fig Forth 8. SMD ( Small Memory Dump from manual ) 9. TCPY ( a tape copy program that I wrote that only displays errors but doesn't stop. Useful for recovering bad tapes, keeping auto-start info and general copying of tapes ) 10. Poly Assembler ( I've not figured out how this works and I have no docs ). 11. SAVE, PEEK and POKE extensions, I wrote, for TinyBasic. 12. Last, I have image files for Tiny Basic to be put onto two 2708's that would go in the two empty sockets of the CPU board. A ^C would start TBASIC. I would be willing to make copies of all at cost for tapes and mailing. If anyone is interested, let me know? ( Sellam I. and Larry P. are already on my list ) If someone wants EPROMs for the TBASIC, I can program them for you, if you supply the EPROMs. Also, let me know if you want the tapes in Byte format, Poly format or both.

[CCTECH] Mystery EPROM programmer

by dwightk.elvey＠amd.com

Hi Rich If this is the one I think it is, there should also be some RAM on the board as well. It should work with a KIM/SYM/AIM. I have one that I've used with my AIM. The software is simple. You just write to the address window for the EPROM a number of times and the EPROM gets programmed. As I recall, the board can be configued to do 2716's or 2732's. Poking around in your monitor can find the memory locations.

Hello, all: While cleaning up in the shop this weekend, I found what looks to be an EPROM programmer board. It's manufactured by Digital Matrix Associates with a part number of 6500-001-PWB. It's about the size of a STD BUS card (4.5" x 6") with a 22/44 pin edge connector and a right-angle 22/44 socket right above it. It has one ZIF socket and 4 empty sockets. Forgot to count the pins, though. It's either for an AIM65 or a KIM, but since I never labeled it when I got it, I can't remember. I'm guessing the AIM65, thought. Does anyone have any info on this card? Rich ========================== Richard A.

What's the best way to slurp up DEC RX50s?

by Antonio.Carlini＠riverstonenet.com

>Primary goal is backup - TELEDISK should do that. Secondary goal is >to produce image files suitable for use with simh and E-11. Backup implies an ability to restore, and, at least for me, TELEDISK has problems doing that. On my system (which at the time was a K6 233MHz machine) 3.5" disks could be restored without issue but 5.25" disks could not be reliably restored (this seemed to apply to both 360KB and 1.2MB disks). I assume that restoring RX50s will be no easier. It might just have been my system, it might just have been my copy of TELEDISK (there seem to be multiple copies floating around) but it did not fill me with confidence. Is the TELEDISK format freely available? If not, restoring your disks may be difficult once the last PC has expired! BACKUP/PHYSICAL has the advantage that you can at least work out where each block ends up (since the BACKUP source listings are available). (If anyone has suggestions for "imaging" 360KB floppies, 1.2MB floppies and RX50s using PC hardware running Windows or Linux or NetBSD, I'm all ears. Preference given to those with practical experience of restoring the data afterwards ... I'm not keen to run through several hundred floppies just on the off-chance it will be worthwhile.) Antonio

The switches on the solenoid were always for the ignition resistor bypass and the main switch for the starter motor. The only time I've seen this is on the Ford type starter where the pull in for the gear comes from a pole piece in the started motor. The pole piece would pull in and change the field to be series with the motor armature. There was a separate solenoid that powered this and it always had the full coil current and only switched the current to the starter and the ignition resistor bypass. Pinball machines do have what is called a EOS ( end of stroke ) switch that is used on flippers to reduce the current for holding. Dwight

Bulk Tape Eraser / 486 Linux box problem SCSI

by john_boffemmyer_iv＠boff-net.dhs.org

Now you two have really given me an idea. Scary as that might be. Building a computer desk and office out of failed computer parts. Now, just to win the damned lottery so I can actually spend at least 5 minutes a day figuring out how to obtain enough parts and break them down into something workable. Grin. On another note: This is on topic since ALL equipment except the replacement hard drive are over 10 years old. I have a 486x33Mhz with pure 30pin SIMMS (no 72 mix here) maxed out at 16MB (16 of these x 1MB), with EISA bus. I have an Adaptec 1740A SCSI controller, a Trident ISA video card, a Creative Labs Sound Blaster ISA, a DCA ISA / MCA Token Ring Adapter (obviously using the ISA), a 10Mbit ISA NIC, Generic I/O card with floppy and IDE, 32x IDE CD-ROM and a Seagate Elite 9 ST410800N 10/9GB SCSI drive (set to ID 0 since the 1740A insists that you use ID 0 to boot the machine). I am trying to load Slackware 7.1 on it. Problem: how do I get the damned install from floppy to see the CD-ROM and see the hard drive properly? It goes to start the installer and it comes up loading the initial install kernal with this error: SCSI host found at (0) Unable to load SCSI host (0) Now, mind you, I can see and play with the damned drive in PC DOS 7, booted >from Floppy. Why not in Linux? I am removing hair at this point since it took me 2 weeks to restore the system to a working state as it is. Also, anyone know of a friggin GUI utility that allows you to still use the keyboard (tab, space bar, etc) for drive partitioning and editing to set up a Linux partition (possibly as a bootable util from a floppy?)? Guessing in a command prompt really blows. The plan is to get it up as an actual server on the broadband cable here so I can offer email and web space in the future (trying to help friend of mine over at dhs.org unload some of the users on his aging server and bring them up to date). Any input will be greatly appreciated. -John -John At 11:44 AM 6/19/02, you wrote: > > From: Chris > > > > > Or a drink coaster. The circuit boards is good as a backer for a > > >notepad.
