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.

[CCTECH] Mystery EPROM programmer

by RCini＠congressfinancial.com

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.

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 9 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.

[OT] Waddizzit??

by mythtech＠mac.com

>I just picked up a PC at the local thrift store. It has a board that's a >half-height ISA card with the designation SCB5 Junior. It's got a >mini-din at >the backpanel, though it's definitely not the keyed sort used by a mouse or >keyboard. I've got to admit, I'm puzzled. I think it is a Logitech ScanMan scanner interface card. If it is the one I am thinking of, it is for the ScanMan 256 and ScanMan Color hand scanners. It has 2 dip switches and an 8 pin mini din right? If that is right, then it is probably the board I am thinking of. I have one here somewhere (but no scanner for it). I found info about how to config it somewhere online (but not Logitech's site IIRC, however I think they might have had a link to the actual manufacturer's site, or maybe I just found info via a google search... not quite sure). Wait... ok, found a link for you: <http://marvin.tele-net.net/storm/xxx_faq_lg.htm#2651>, they have some info on how to set the dip switches. -chris <http://www.mythtech.net>

IBM Technical Reports Archives online?

by foo＠siconic.com

Does anyone know of a server somewhere online where IBM keeps all it's archived Technical Reports? I've spent considerable time navigating through IBM's site but have not been able to turn anything up older than a few months. Specifically, I am looking for the following Technical Report (numbered RC16672): S. R. White, S. H. Weingart, W. C. Arnold and E. R. Palmer. Introduction to the Citadel Architecture: Security in Physically Exposed Environments. Technical Report, Distributed Systems Security Group. IBM T. J. Watson Research Center. March 1991. [RC16672] Any help locating this would be appreciated.

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

New things

by pat＠purdueriots.com

Well, today I managed to go out to Univ Salvage and get myself two things that look 'fun to play with' RS/6000 7013-580 1-9 Video 2-1 Ethernet 4-4 SCSI? adaptor 128MB RAM (16x8M 80ns SIMMS on two cards) FDD CDROM (no hard drives) The system had its 'doors off' and its keys 'in the ignition' (yay!). Data Systems Design Model 880-D8. It has a DS Shugart 8" floppy drive in it (which I intend to use to fix my Altos 8000) and a SA-1000 interface 8" hard disk inside (which I intend to use to fix my TeleVideo TS-816, if possible. Quite the finds for $10, eh? Now if I could get myself to concentrate on this paper I have to write.. -- Pat
