I wonder what the state of the art in Atari emulation is? I'm an old Amiga person rather than Atari one so every so often I get an urge to go buy an Amiga 4000. Instead I fire up my copy of E-UAE running AmigaDOS 3.9 and the urge goes away. It runs some old games better than my A500 ever did and I can run the AGA stuff my older machines never could without massive modifications. My eventual goal is to get an old netbook and dedicate it to just running WinUAE. Perhaps the OP might find an Atari emulator the same way? > Date: Wed, 26 Dec 2012 20:09:30 +0100 > From: Jonas Otter <jonas at otter.se> > On Tue, 25 Dec 2012 20:33:36 -0800, "Zane H.

thinking of selling my PDP-11/23+

by charlesmorris800＠centurytel.net

I have a functioning PDP-11/23+ system (4 Mb RAM, 16-line serial card, two RL02's; RT-11XM, TSX-Plus) in the half-height "corporate cabinet". Since I got it running and played ADVENT a few times, I find I never use it... would anyone be interested in buying it? If so I'd much prefer you came and picked it up; located in West Plains MO. Email me for pictures. thanks Charles

CFFA3000 and Apple III?

by wheagy＠gmail.com

Mike, Thanks. If that's the case, let me try making a couple more disks using different disk images that I can find online and see if I have any better luck. If not, I'll try the drive speed adjustment. If you don't mind sending me a pointer for that, it sounds like it would be a good thing to have regardless of whether I need to use it this time or not Thanks, Win --------- Hi Win, It sound like the floppy you created from the image is good -- usually you get the immediate "Retry" message if the III can't recognize the disk at all. As long as you used the CFFA to create the disk from the image, just as you would an Apple II disk, it should work. >From what I've experienced, what you're seeing is usually (but not always) one of two things: 1) The disk image you used to create the image has a driver installed for a piece of hardware that isn't present in your system (i.e, a ProFile drive) and SOS has loaded the driver and is waiting for the peripheral to respond. SOS is supposed to be smart enough to realize that hardware isn't there and move on with the loading process, but it doesn't always work that way. or 2) your drive needs to be adjusted. I have about two dozen Disk III drives and every single one of them required a speed adjustment before they would work when I acquired them. LMK if you need the procedures for that. - Mike

CFFA300 and Apple III

by wheagy＠gmail.com

Mike, I read the relevant chapters and have a bit better understanding of the Apple III...I think. I tried making an SOS disk today using my Apple IIe and the CFFA3000 with some Apple III dsk images i found online. I used ProDOS and was able to format the floppy and it appeared to copy the image onto the floppy. At least it said it was successful, but when I tried booting the III with it, the drive spun for about 3 seconds and then stopped and nothing else happened...nothing on the display. Should it work to copy a floppy like this using ProDOS on a IIe for use on a III? Is there another utility that would be better suited to copy the disk? Thanks, Win Unlike the II, which is relatively easy to configure to boot to any (bootable) storage device in nearly any slot, the Apple III tries to boot only from the internal floppy drive, and as Eric pointed out, you'd have to roll your own ROM to change that behavior. The CFFA3000 works nicely in the III, but you lose the Drive ][ emulation capability and you can't boot directly to it. In the Apple III, everything is seen as a device and requires a driver that SOS loads as it boots in order to be accessible to the system during operation. You can't (easily) boot directly to the CFFA because SOS requires a driver to be able to recognize it. Fortunately, SOS is close enough to ProDOS that you can use the CFFA in an Apple II to create floppies from the images you downloaded. I'd suggest reading this PDF for more on how the III works: http;//apple2scans.net/scans/manuals/3rd.party/OMHGYA3.pdf It's the Osborne McGraw Hill Guide To Your Apply III. Pay special attention to Chapters 3 and 4. LMK if you have any questions about all this. - Mike

Dead Intel MDS

by williams.dan＠gmail.com

Hi, I have managed to get around to having a look at this machine. It is a model 231. I am getting nothing on the screen and no beeps when in diagnostic mode. The PSU is on and the fans are running. I have checked the schematics and the voltage is correct on all pins coming out of the supply and there is voltage going into the screen. The screen is not 'firing' up as I would expect. I am not an expert on CRT's Anyone know anything about these machines or how to proceed. I have found online service manuals for the screen and machine as well as full schematics for both. Thanks Dan

I see, I think you mean the EGC (Enhanced Graphic Color board). I never had an EGC board but I have the user guide of it. The board adds three bit planes to the one of the Indigeneous Card (IND), so it provides 16 color capability to the higher screen resolutions and it adds the flexibility of a color/shades of grey Look-Up Table (LUT) The video bit planes are laid out as folows: A0000h-A7FFFh Bit plane 0 (EGC) A8000h-AFFFFh Bit plane 1 (EGC) B0000h-B7FFFh Bit plane 2 (EGC) B8000h-BFFFFh Bit plane 3 (IND) The MDA card has the following memory layout: 4k of RAM at address 0B0000h for its display buffer. This address is not completely decoded; the entire 32k from 0B0000h to 0B7FFFh is filled with repeats of this 4k area. I/O addresses 03B0h-03BFh. As you see the memory of Bit Plane 1 overlays that of the MDA card completely. So I think it will cause serious problems. Are you familiar with the card? Do you have one? Greetings, Hendrik

On the PDP-11 processors and RAM (and > QBUS to UNIBUS adapter -- KTJ11, I think it is called -- in the 84 and > 94) the PMI is all on only the CD slots of the board. Correct, PMI memory on PDP-11 machines is just communicating on the CD slots. No ribbon cables. However, I'd like to point out that the 11/83 also can use PMI memory. The thing to understand is that for the memory to be connected on the PMI, it needs to set *before* the CPU on the Qbus, and be PMI capable. The same memory placed *after* the CPU means it acts as normal Qbus memory. Some difference in performance. When sitting in the 11/84, the memory sits after the CPU, but all the first four slots are PMI slots in that box, always. Actually, PMI is also not only on the CD slots. A few signals in the AB slots are working differently than in a Qbus as well. And to point out one last, obvious thing, the PMI on the VAX is a bus, even through it's on a ribbon cable. Why would that make it not a bus? Johnny

Setting up a DMC11 on TOPS-10

by robert.jarratt＠ntlworld.com

Some work is being done to get a DMC11 emulation into the SIMH PDP10 emulator. I would like to get DECnet running on TOPS-10 over the DMC11, but I have absolutely no idea where to begin, I only ever used TOPS-20 and never with DECnet and never did any admin things on it anyway. Can anyone offer any pointers on how to get started? Before anyone asks, I understand that TOPS-10 uses the DMR11, but this is so similar to the DMC11 that it may not notice the difference or I can fix the emulation for the minor differences. Thanks Rob

Kaypro help

by brain＠jbrain.com

It appears I am clueless about Kaypro machines * The machines: 4, 4+88, 10, and 1 * Can't get anyone of them to boot. All but the 4+88 boot to a screen, but nothing else. I have a K1 CP/M disk someone from the list sent in 2009, and I tried that in all of them, to no avail. The disk on the 1, at least, seems to work, as it knows when I put in a non OS disk, and tells me, but nothing else. If it had a read error, would it not tell me? It does move the head and such when I insert the OS disk, so it appears to be reading it. Still, it never drops to a prompt. * Looking for parts. The 4 needs ESC and 7, the 10 needs 'right arrow', both the 10 and 4+88 need the little telephone jack in the KB. 10 needs a new fan, it's getting power, but no spinning. 4+88 needs fuse holder, and 4 needs reset switch. Missing a small screw on the KB catch as well. Before I start trolling eBay for a donor Kaypro, I thought I would ask around here. * The 4+88 needs major help. drives don't respond, screen does not come up, nothing looks alive. I'd ship it to someone who wanted to take a look at it, as it'll take me a year to start going through it. Or, maybe I should put the 4-84's guts into it (keeping the 8088 and extra RAM) and use the rest of the 4-84' for parts? All except the 4+88 are in good cosmetic shape. The outer top shell of the 88 is in rough shape, though the KB is in great shape save the RJ14 jack (or whatever they are called) My regret is that I should have tested the system disk I previously received as soon as I got it in the mail, but we moved shortly after receiving it, and have not had the items out of storage since 2009. So, the disk could have been mishandled by me or the movers in the interim.Jim -- Jim Brain brain at jbrain.com www.jbrain.com
