Each case is an individual when the following are true: *Hardsector or non PC producable media. * No monitor or front pannel to interact with. An example is the NS* Horizon system. The only rom is small and JUST enough to boot the OS. The disk is hard sector. Without one of the following as bootable, UCSD Psystem Pascal, NS*dos, CP/M for Horizon your dead. The fix, one of several really. You need about 1k of eprom in the system with a very basic monitor that allows setting memory moving blocks of memory and the like. the CPUB (STD NS* Z80 board) can be populated with the bits needed to use a 2708. Or if available a SBC880 (has ram and rom on it), Compupro CPUZ (with eprom installed). or use a Eprom/Rom card with a monitor program installed to get software console. The basic theme here is being able communicate with the base hardware. Having an IMSAI or ALTAIR front pannel machine works too. > >What I was looking for were answers to the following problems: > >1 - I have some hard-sectored disks for my Vector MZ; how do I archive those? Serial port to the serial port of a emulator. Serial por tot PROCOMM on PC. Once again if the machine is like the NS* you will have to use the native OS to write a program to upload sectors for assembly as an archive. If the native OS is LIKE CP/M or similar with and editor, assembler and debugger your golden. >2 - Assuming I do, how do I or you recreate them? The reverse is harder and very system dependent. First you must have enough rom with a program (See NS* case) to communicate at some level. If you can do that it's possible to hand enter code to do whatever is needed to assemble media. Painful, you bet but I've done it. >3 - I have a SSSD 8" CP/M Visicalc distribution disk; how do I send it to you in a > way that you can re-create a 5" disk for your SystemX (especially if you only > have one serial port)? Procom or other terminal emulator and a CPM program called unload to make into an ASCII hexfile for upload and transport. This assumes you have a system that can actually read it. If not it's just some media and might as well be blank. >4 - I have a version of Cromix+ for Cromemco on DSDD 8" disks, consisting > of one bootable disk and a tar file spanning three more disks; again, > what do I put on my site or email you so that you can install it on your > System 1 with only a 5" FDD? See above cases. >5 - And just to round out the list, I have a copy of Unix for the Cromemco, which > is on one bootable 5" disk and a tar file on a DC600 tape. What do I do > with that (serious replies only pls :)? IF you do not have the system and drive that wrote that tape the usefulness is seriously in doubt. It really is close to finding a reel of magtape on the side of the road maybe worse. You MUST have the drive or one of the same type with similar interface or reading it may be just an exercise. The bootable 5" disk you boot it and then write a utility to read it serially to another box (PC whatever). The only one that can help is someone thats in the same space and with similar or same hardware. IF the media matches hardware you have running another OS then sending sectors via serial line is doable ad my even be easy depending on OS. Systems like that you have to know it inside out and side ways. Unless some one can using a similar one write you disks all the code on the internet is mostly meaningless if you can not enter it somehow and execute it. Generally speaking if I can talk to the hardware, and there is at least one serial port the problem can be beaten but usualy as a one off case. Best example I can give is years ago. NEC PDA-80, one of 12 in the country and I had 4 of them, two were operable. NO OS. Front pannel machine with a disk controller for 5,25" floppy that with a few commands could read or write a sector of data to/from it's buffer. Task, put CP/M 2.2 up for the first time. The only system available was intel MDS 8". Note this was before the PC had IBM on the front. The transfer media was paper tape and ASR33 TTY! A program was written and assembled on the MDS to implement a simple bin loader, the loadeer was for hand entry via the front pannel. That loader read the first tape that had a hex loader to load the hex tape with CPM (6.5k of code!). It took six tries to get the CP/M prompt for the first time and two more to get a floppy written with boot tracks. Then I had to get, PIP, STAT, ED, DDT, ASM, LOAD and an improved BIOS source transfered all as hex format paper tape. Pip was first as it is a file transfer program. It can be done, and it's not always easy. Allison

Uh, not always so... I have plenty of software that runs directly off CD. I'm not making a copy of it to run it. Unless you're implying the process of reading it into memory to execute is copying it. IMHO that's a mighty fine line.

Fwd: PET stuff to rescue in Sweden

by legalize＠xmission.com

Date: Thu, 15 Dec 2005 22:21:40 +0100 From: Anders Carlsson <anders.carlsson at sfks.se> To: cbm-hackers at ling.gu.se Message-ID: <Pine.WNT.4.64.0512152208170.-686657 at crashders.bredband2.com> Reply-To: cbm-hackers at ling.gu.se Subject: PET stuff to rescue Hello. While this is not a buy and sale list, I wish to make an exception. Tonight, I visited a man who used to be a Commodore reseller as well as having his own program development company, working towards Datatronic, the Swedish Commodore agent during 197x-1985. I went to his house in hunt for VIC-20 and perhaps C64 items, and found a bunch of stuff, described more in detail on the Denial web forum. However, his basement and garage are crowded with PET stuff. Computers like 3032, 8032-SK, 600, 700 and perhaps more. He needed some space in the garage, and has already thrown away a lot of CBM 600/700 series! Disk drives like dual 3040, 8050, 8250, 8050LP and I don't know all the model numbers, as I have never been much into the PET/IEEE series. Hard disks like 9060 and 9090 (or did I misread?). Some 3rd party hard drives called Corvux or something like that. No IEC based (1541 or newer) disk drives though. Printers. Monitors. Lots of business software, floppies a mass. Docs. PET printer switches. Modems. Everything was so tightly piled, that I don't even know what's behind all those PILES of disk drives. Most are supposed to be OK too. He even has a small selection of motherboards and loose chips, mainly 6502. He also had a few C64 and slightly more loose VIC-20s with assorted items. So the question is, is this stuff worth buying? I realize the shipping would be a lot of money, probably more than he is asking for the items themselves as he said he is happy if they can come to use. I don't have a complete inventory, partly because I didn't know if there is any major interest in this kind of stuff, and because it was close to impossible to inventory it all. He has had this stored like this for 10+ years, and just recently begun to clean out the garage and basement to have room for his new hobbies and grandchildren. I suppose it is no immediate hurry to pick up the stuff, but it shouldn't wait too long. I suppose the best thing is if interested parties answer me privately. At least when it comes to disk drives, I can almost guarantee there is enough for everyone.

S-100 Memory board

by doc＠mdrconsult.com

Folks, I have an S-100 RAM board made by Measurement Systems and Controls, Inc. Model No. DMB6400. It came in the Cromemco system I'm cleaning up, so I ass-ume that the DIP switches are correctly set for the Z-2D's current configuration, but I'd still like to know more about it. Does anyone have the manual for this thing? Doc

Free BIOS (was Resources for DOS (was: DOS Compatable OS))

by dwight.elvey＠amd.com

>From: "Robert Armstrong" <bob at jfcl.com> >> >> The BIOS is written in Forth > > A BIOS written in Forth? I dunno - I don't want to start any flame wars, >but I'm just not comfortable with that :-) > Hi Bob This is done more often than one would realize for production machines. Forth has the ability to abstract in most any direction that one desires ( end encourages it ). This means that ( if done properly ) a BIOS written in Forth would have its coding done in such a way that reconfiguring for different hardware and even often for different processors can be done with minimum effort. I've seen coding in such a form that the changes looked more like copying the data specs than actual coding. Of course, for someone that can't read or write in Forth, it may look like a difficult project. JMHO Dwight

I usually also write something to put an file back to an image. Often the write back of a file is as simple as I can make it. I usually write to an formatted image with no other files. This makes allocation easy. For CP/M I've only copied files from archives and not images. I've then transferred the files serially to my IMSAI. If it is a binary, I convert to HEX and then use the debugger to write it to a file. For CP/M-8000, I've written code to extract from a 8 inch image and then write these files to 5-1/4 images for the Olivetti M20. In this case, I've always build a new image with complete files for that image and not added files to a disk with files on it. Again, this is the easiest way to handle these. I've seen a few utilities on the web to read and write files to images but I've never used or needed any of these. I an usually interested in learning that particular systems file format and find the best way to learn it is to write something to transfer files. Dwight

Motorola MVME machine available. (UK)

by robert＠irrelevant.com

OK, I've finally decided I'm never going to get a chance to play with this, so it's looking for a new home where it can receive the love and attention it deserves. It's one of those black stacking motorola machines - just pile up discs on top ... (and connect the scsi and control and power cables on the back..) Main unit. P/N 01-W2522D01A. Second bay P/N 01-W2519D01A. Boards are labled MVME 187 and I/O. Latter has the scsi and control on it, 4xserial and 10baseT and AUI ports. And it's got a tape drive in it. No floppy. My understanding is that this machine was only in service for a matter of months, maybe even weeks, then the user reverted back to their previous (accounts) system and this ended up under a desk for the next several years, before I rescued it. It's therefore not been powered up for about ten years ... I assume it's still loaded up with whatever it ran (Unix, SVR4 from memory, plus applications). It comes with no cables, no documentation, no passwords... I believe you can run NetBSD on it.. Free to loving home, for collection only from Salford, near Manchester, UK. Also available at the same time (take them, please!!!) two or three Wyse dumb terminals (Wy-120 and Wy-30), at least one of another make, multiple pentium-1 and 486 PCs in various conditions, some printers, monitors, etc. Interested parties please email me on robert at irrelevant dot com.

Information requested on Vector Graphics machine

by jplist＠kiwigeek.com

Greetings folks; So last night during the tornado watch in Iowa I was muddling about in my basement with my wife (Seated listening to the radio) and rediscovering the treasure trove of Good Stuff I have stored down there. I came across a Vector Graphics machine that I've had for a few years now and not even poked a serious look at. This Vector Graphics machine is not an all-in-one like the ones I seem to have found online, but in two desktop style chassis', one containing the S100 cardcage and cards, and the other a rather large MFM hard disk. I am totally unfamaliar with this machine, and google seems to be providing me with few well descriptive pages on what the machine is and about the Vector Graphics company. What I do know: The machine is Z80 based on a "ZCB" single board computer which sits in the S100 bus. It also has a hard disk/floppy drive controller board, what appear to be three memory boards and three "FlashWriter II"s which, all share one wire in common with a memory board (A big question mark over that one). Alas some philistine couldn't be bothered unplugging the unit from whatever it once hooked to, and snipped both the ribbon cables to the drive chassis as well as a ribbon cable that lead to an unknown device (possibly a specialised graphics display). Replacing the cabling isn't a problem, of course, but whatever the blue ribbon cable goes to definitely did not come included. All information greatfully received; Pictures of the poor thing (and copious asian beetles) here: http://www.kiwigeek.com/misc/VectorGraphics-front.jpg http://www.kiwigeek.com/misc/VectorGraphics-hdd.jpg http://www.kiwigeek.com/misc/VectorGraphics-top.jpg My thanks; JP
