But, it only has dram - which is a bit more difficult to interface than sram. DE1 gives you both. Then again, DE1 comes with an older generation FPGA, that is bigger than the one on as well. It calls for a comparison table, really - or, you might just order both? The boards are really not that expensive. And, both can run a PDP11 - and without needing a PC attached after the flash is programmed, by the way.

It's easy to look backwards by a quarter century plus, on "Fifth generation computing" as a failure, but a lot of interesting and durable stuff came out of it (if not the "fifth generation computer"). The Japanese large-system peripherals of the late 80's and early 90's really cleaned the clocks of any competitors, not just the reliability of the electromechanical transports, but in large part because of signal processing done in NEC/Fujitsu/Hitachi/Toshiba signal processing chains.

VHDL PDP11

by sytsezelf＠gmail.com

>> The only interfaces seem to be serial lines. What there is now is basically a KL11 type serial controller - the simplest version of a rs232 controller, without the option to set baud rates, byte lengths, parity, without modem control, and without any error detection capability. ie. What you would connect a terminal or hardcopy console to. >> I take it that any DEC peripheral that is connected via a serial line could >> possibly be supported. More specifically: any device connected to a KL11 - or whatever variant of that that would be accepted by the software that interfaces to the controller. >> Other than the serial lines are there any plans to produce an interface to >> any of the standard DEC PDP-11 busses ie Uni and Q22? If you mean, do I have any plans to make it possible to connect original "real" Uni/Q controller boards to the FPGA? No, I don't - firstly, because I don't have any of those boards; secondly, because it would likely be more appropriate to recreate the functionality in VHDL as well. And maybe easier - because, interfacing would mean that the timing and electrical behavior of a 'real' Uni/Q bus would have to work with the timing and electrics of the 'logical' bus inside the FPGA. That would not be a trivial challenge. >> An Ethernet port (co-ax or UTP) would be nice. I agree :-) I do have some thoughts on adding one of the Ethernet controllers, but that is a nontrivial job - it will probably take me at least a couple of months to get it working. And, unlike RS232 ports, Ethernet hardware differs across FPGA boards - some have a phy, some have a complete controller including dma to memory, some have wire/transformer only, most have nothing at all. So there too is a bit of a challenge - which situation to build the VHDL for?

WTD -- AMD Am95C60 datasheet + register map

by classiccmp＠philpem.me.uk

Hi guys, Does anyone have a full datasheet for the AMD Am95C60 graphics controller LSI? (also known as the Quad Pixel Dataflow Manager, or QPDM) I'm trying to reverse engineer the firmware in a piece of test-and-measurement gear, and the most I've been able to find for this chip is an abridged preliminary datasheet, which is pretty useless (lists the registers, but not what the various bits do, and contains no command list for the processor core). Basically, the box has some hidden features which I need to access to do a re-calibration. The manufacturer has binned all the documentation (quote from their tech guy: "Omigod, we last made those in, like, 1992... I can't believe those things are still around!") so no help there... :( Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

Speaking of keyboards...

53CF94-2: same as AM53CF94?

by fraveydank＠gmail.com

I just bought a few LSI/Symbios/NCR 53CF94-2 chips, and I'm having a spot of trouble finding their datasheets. The web is replete with datasheets for AMD's AM53CF94, which looks to be the 10 MB/S version of the 53C94. However, that datasheet mentions that there is a 3.3v variant available. Does anyone know if the 53CF94-2 is the same as what AMD calls a 53CF94? It's used for the SCSI controllers in the higher-end DEC AXP 3000 machines, if that's any help, so I assume it's the same, but I'd rather not cook one finding out. - Dave

DEC card cage plastic rails?

by fraveydank＠gmail.com

My 11/23+ is currently in a small 4-slot backplane. Said backplane came to me missing 2 of the plastic rail guides on the card cage to get the cards in properly. This isn't a terrible problem during operation for the quad-wide card I've got in there, because the insertion/extraction clamps and the backplane itself hold the card in place just fine once it's installed, but it does make the insertion/removal problem a pain in the ass. Does anyone know the part number of the rails? I've had a devil of a time finding that in the service manuals available. I'd really rather just have a better backplane, but that costs more money than I'm interested in spending at the moment. In a related note, does anyone have a BA23 enclosure they're looking to get rid of? - Dave

Radio Electronics Articles by Author Ross Ortman

by brain＠jbrain.com

I was wondering if anyone had softcopies of Ross Ortman's R-E articles, probably from '86 or so. He owns Dakota Digital here in town, and lamented that he never saved a copy of the articles he wrote. I thought maybe someone might have copies electronic, or otherwise. Jim -- Jim Brain brain at jbrain.com www.jbrain.com

Good Quality 'modern' keyboards

by md.benson＠gmail.com

I'm looking for a good action, high quality keyboard of the same action/type as an IBM Model M or the really great Cherry keyboards of 'the day' to use on modern machines to code with and work at a terminal. My Logitech G110 is fine for general work (it's a decent keyboard in it's own right) but the 12 macro keys on the end confuse the b-jebus out of me and also the key-spacing is designed for gamers no typists. I don't want to fudge an older PS/2 keyboard via a USB adapter as it generally doesn't work 100% right and I occasionally get keys dropped or doouble-typed. I also need the 'Windows' keys that a lot of older decent keyboards lack. I'm willing to drop decent money to get one, so anyone got any ideas? -- Mark Benson http://DECtec.info Twitter: @DECtecInfo HECnet: STAR69::MARK Online Resource & Mailing List for DEC Enthusiasts.

Emulex CU02

by rob_j37＠hotmail.com

I recently acquired a machine that contains an Emulex CU02. I suspect it is a Qbus SCSI controller, but I am not sure. I have not been able to find any information on this card, all my searches find is dealers selling them, but no description. Does anyone have any pointers to information on this card? Thanks Rob

grrr....an apology

by mcguire＠neurotica.com

Dammit. I've been trolled once again. I have very little tolerance for (what I perceive as) cluelessness backed up by arrogance, and something in my personal makeup just can't let misinformation stand. I try very hard to know the difference between facts and opinions, and I think I do that much better than many people, so I tend to be (and try very hard to be) pretty certain of my facts. That part isn't the problem...feeling the overwhelming urge to "correct" people is. I don't do this out of arrogance. I hate to see people laboring under bad information or false assumptions that may bite them in the future, so I try to help. I've done this stuff, and nothing else, all my life and I've been fortunate to have learned a lot from some very smart people and a whole lot of varied experience. There are people here with both a lot less and a lot more experience than I have; I like to get information from the latter and give information to the former. This backfires when people with too much time on their hands and a desire to push buttons decide they want to rile me up. I don't have time for this. I'm a busy guy, and this is a distraction that just ends up with me in a bad mood and falling behind on my work. So...Once again, I Have Been Trolled, and I apologize. I promise to try to be better about it in the future, for my own sake as well as the sake of others. -Dave -- Dave McGuire New Kensington, PA

All the VAX talk has me wanting my VAXen back :(

by hexsane＠gmail.com

In the early 2ks I had gotten my hands on several VAXen (VAX Stations, MicroVAXen and QBUS Rack and Pedestals). Lacking the space and having a money crisis I had to give up all of them. Now I want another one so I can fire up NetBSD :) Anyone have a spare VAX Station or other small VAX sitting around they want to part with? Or even a larger one if you're close to Omaha. ;) -Matt

Things I should have learned in school

by fraveydank＠gmail.com

I never really dealt with Fortran in university, and if I had, it probably would have been in a Unix context. Anyone have some pointers to me on how to process command-line switches in VMS from Fortran (I'm specifically tinkering with f77, but I suppose f90 should do; it's a matter of environment)? I guess it would be good to point out that I'm essentially a total neophyte when it comes to working with systems that are not UNIX (or bare metal, or classic Mac OS). Best I can tell is that I need to call either a SYS$ or CLI$ library function, but I'm a bit lost in the giant manual and Google doesn't seem to be helping me find sample code. The "standard" (which probably means UNIX-standard) iargc() and getarg() functions don't seem to work, at least not without some external library linked in, so I assume those aren't the way to go. - Dave

Looking for some parts help with an old computer (or two).

by mnealey＠gmail.com

Hi, I am breaking out some old computers I have and need a couple parts to get them working. The computers in question are an Alpha ES40 and an HP ZX6000 workstation. Anyone out in list land happen to have any spare memory for an ES40? Any size will do, just need at least 4 pieces to work. I want to run some OpenVMS on this guy so any help would be great. Also, I need some Itanium 2 processors for the zx6000. Not worried about speed but the faster the better I guess. And would love to get two if possible. If ya have anything like the stuff I'm looking for laying around, let me know what you want for it. Thanks!
