Another and perhaps the simplest way to archive sys34 or 36 pgms to diskette or cd is to use the 5250 pc emulator card or a clone card and the pc support pgms on the pc and sys/36. the emulator turns a pc xt or at into a 5251 terminal and does the ebcdic/ascii conversion for pc to 36 printer files. there are many different versions of the emulator cards still out there some will even run in windows. i even saw a pcmcia version for a laptop. you can save disk or diskette - library's,files and members on the pc from the 36 then transfer the diskette to a windows machine if needed and put it on cd. useing the same process one could even send a copy of sys/36 pgms via email. the labels and owner id must match the pgm distrubition diskettes label if copying a 8 diskette. then a person could do the reverse to get the files back on the 36. i have the emulator card but have not played with the copy to pc feature yet i got all this info from the pc support 36 manual. i am not sure how much the ibm standards differ from the shugart or other standards. ibm had the 1d and 2d diskettes and both had a low and hi density format (format 1 or 2). do keep us posted about which process you end up useing as i want to archive all of my fresh 8 in copies also. i hope the non ascii data of sys3x data (ebcdic) dosn't go down to the binary level.

To: cctalk(a)classiccmp.org From: "Colin Eby" <ceby2(a)csc.com> Date: Sun, 26 Jan 2003 13:44:09 -0500 Reply-To: cctech(a)classiccmp.org Folks -- Thought I'd continue my unreasonable begging from the previous note back to Bill. I'd like to take on a little project of creating archival images of S/36 media. I've made a duplicate of most of what I own on fresher 8" stock. But I don't think that's a long term strategy for avoiding the inevitable ravages of media corruption. What I had in mind was something like a 'dd' dump of each disk that could be reloaded to fresh 8" media when required. I haven't given this too much thought so bear with me.... I'm working on a list of questions and puzzles to accomplish this goal.The first obvious problem is media to hardware integration. If memory serves, I read somewhere that IBM used an oddball disk format (Sellam, you might know this). 8" Shuggart drives come on the market from time to time but, would they, using low level drivers, be able to make a physical block by block copy of IBM S/36 disk data? The second problem is hardware to hardware integration. Has anyone had luck integrating a 8" drive with a more recent machine? And what are the alternatives? I presume this could be done on DEC hardware and then sent to any open platform over a network connection. Has anyone gotten an 8" floppy operating under an Intel based Linux host. That would seem the obvious media transfer station because of the wide range of hardware compatibility. Once these first two steps are done, any basic disk utility ought to make short work of creating binary dumps. An alternative approach might be to copy the disks directly on the System/36 host using platform native tools then sending the file across some form of network connection. The problem is I haven't a clue how that would need to be done. I've never read any low level API for S/36 as a platform. IBM seems to have kept anything harware layer proprietary. Any and all thoughts welcome. Thanks, -Colin ceby2(a)csc.com Senior Consultant, National Performance Engineeering Practice CSC Consulting.

ibm sys/36 5360 basic needed

by n8uhn＠yahoo.com

Ive always wondered about the 5363 the pc size'd 36. the pc support manual does mention it. the models are 5360 - large sys/36, 5362 - small sys/36, 5551 small model available only in japan and the 5363 pc sized sys/36. the pc support calls the 5363 a "system console". as far a spp is concerned, the 5363 uses 5 1/4 diskettes and the ssp on it is for the 5363 only. i'm not sure about the 8 in versions of 36 ssp. sorry i have no 5 1/4 in ssp diskettes. i don't think the 8 in, 5360 languages or office products pgms will even work with the 5363, they will run on the 5362. i have the same 5360 unit that you have - do you have the service manuals for it? you may want to hang on to the 5360 - you can do more with it and the 8 in diskettes are more commom to find. btw - do a search for 5363 or sys/36 and you should find a page that features a 5363 on it you may want to email him about the diskettes. are the tape drives on your 5360 the r2r or cart drives?

You wouldn't happen to have any of the SSP on 5.25" would you. I have a 5363 I've never successfully IPL'd . And while I'm turning your request for assistance on its head... you wouldn't happen to want a 5360 would you? I have one in need of a good home. I don't even have a garage so I'm paying storage for the beast (2 tape drives, 2 printers, expanded main cabinet with additional disk platters and the magazine version of the 8" floppy). Maybe I can be more helpful if you have other S/36 needs in future. I have a lot of the books and even a few already scanned to PDF. While I'm begging, I don't suppose anyone out there has the Office suite for S/36, or any interesting applications? Or maybe someone wants to be free of a 5364 (a little easier on the electric bills than the 63, 62 or 60). My systems only have SSP, and I have a perverse desire to get some use out of them. -Colin

How many PDP-12's are there now?

by root＠parse.com

So... all this discussion about PDP-12's has got me curious. How many of them are there in existence? It would certainly be interesting to get a list of machines and at least city locations -- I'll start the list: Ottawa/ON/Canada (mine) Roswell/GA/USA If anyone wants to send me info, I'll volunteer to collect and put it up on my website (I won't put email addresses or other incriminating evidence unless you want me to :-)). The other interesting thing that this discussion begs is the topic of (borrowed term) "biomagnification". It's from the environmental field, and basically relates to how bigger animals get more than their "fair" share of poisons because they eat smaller animals which have already concentrated the poisons in their systems. I've borrowed the term because lately what I've been thinking about is the accumulated collections of people who are no longer interested in collecting -- in this case, instead of just getting one or two machines at a time, you tend to get "clusters" of machines -- hence "biomagnification" :-) So... any collectors out there getting rid of PDP stuff? :-) Cheers, -RK -- Looking for Digital Equipment Corp.

Taper proof tools.

by fauradon＠frontiernet.net

Hi all, I am looking for one of those tamper proof tool for the sega nomad. It is basically the same shape as the screws for the game cartridges on the genesis but it is so far recessed (3/4 in) that the pliers trick will not work. Anyone know of a source for such tool? Thank you Francois

Casio CFX-200

by rojas_gonzalo＠hotmail.com

Hi: I have a perfectly functional (and I am using all days) Casio CFX-200 Scientific Calculator Watch... But, I am having a problem with it: due to the use of the clock, the lateral buttons was deteriorated and they have sharp borders... And that sharp buttons damage the cuff of my shirts... The local Casio Technical Support (Santiago, Chile) tolds me that it isn't exist replacement for the buttons... Do you know where can I get replacement buttons for my CFX-200 ?... or a replacement case ?... or how I can fix them ?... Best regards, and thanks in advance...

PDP-8: anyone tried NVRAM simulation of hard drives?

by c.morris＠townsqr.com

Has anyone had interfaced nonvolatile RAM to a PDP-8 to simulate an original hard drive? The DF32 fully expanded with four disks was only 256k x 12... Dallas Semi makes battery-backed NVRAM in a variety of sizes. Two DS1258 (each 128k x 16) would make for a very simple interface that would fit on a single card (or at most a double card). Packing the 12-bit words would complicate the interface a little but lower the cost of the NVRAMs. Using an old 3.5 or 5.25 inch hard drive would be very cheap per meg but would also require development of a controller (like the 8051 mentioned recently as an interface to an HP computer). I don't think there were any original drives greater than 1 Mword available, so larger ones would require nonstandard code to support them anyway. Any thoughts? -Charles

Seeking LaserJet IIISi I/O card

by dwightk.elvey＠amd.com

Hi I've seen these come up about once every month or so in eBay. I bought a duplexer for my 3si and an envelope feeder, on eBay. You just need to keep a search going, every few days. I'm sure you'll find one. I'd originally bought a parallel/serial card when I bought mine, surplus, because of the same problem. At the time, I bought it from a printer repair store. It cost almost $200. Later ( about 2 years ) the card failed. I located one on eBay for about $25, I was back on the air.
