Core Memory Interfacing?

by ajp166＠bellatlantic.net

From: Joe <rigdonj(a)cfl.rr.com> drivers and sense amps on it so that might make things easier. However there are some things that you have to do with core and I don't know if they handled in hardware or if the OS had to take care of it. For example, reading core is destructive, that is it erases the contents so you have to store the contents back into it before you do anything else (unless you don't care if it's lost). That seems like it wou! > ld be easy enough to do in HW but I don't know if that's what they did. Not an OS task. It's usually handled in hardware either in the CPU microcode or as a synchronous timing with the cpu such that if the cpu is going to alter the data at the location it's already started the cycle. Some will stop the memory cycle after the read to see if it should write the old data back or alter it, this is usually signaled by the cpu before it outputs a new address. That would be ideal as you have something you may have data on, most of the circuits and even a clue on the timing. I'd love to play with something like that rather than a scratch build.

Computers Manufactured in 1986

It'd be neat to have a system exactly the same age as me :)) I do believe most of us had that figured out. This list isn't really about modern computers. But hands down, the Macintosh would be the most modern of the bunch. Although it's not color-capable, the user interface is has is what Bill Gates stole >from Apple and used to build Windows. So you'd be most at home there. I've been a Mac advocate from the beginning, but for my own purposes, computers with operating systems that provide a text-mode shell, such as the *nixen and its derivitives, VMS, Primos, DOS, are preferable. As someone with a tiny bit of a math background, the ability you gain with a sophisticated command-line environment is great. In most of these operating systems, you can string commands togther like factors in an equation, and perform complex transformations on sets of files all at once. Hard to do that with a Graphical User Interface. To the List: Was the AT&T 3B2 still being made in '86? If so, there's a good choice for him. I even know where he could get one... -dq -Douglas Hurst Quebbeman (DougQ at ixsnayamspayIgLou.com) [Call me "Doug"] Surgically excise the pig-latin from my e-mail address in order to reply "The large print giveth, and the small print taketh away." -Tom Waits

line monitor? Interview 3600

by mmcfadden＠cmh.edu

I found what looks like to be a line monitor. It has two RS-232C DB25 connectors on the back, labeled connector 1 and connector 2, there is also a barrel type connector labeled video out. The front panel which is hinged at the bottom and is the keyboard, folds down and reveals a small monitor. The keys appear membrane contact type. There are buttons labeled send and receive. There is a QWERTY keyboard and number pad and additional buttons. The label is Atlantic Richfield and immediately below it is Interview 3600. It appears to be the size and form factor of a Compaq luggable. There are no card slots or other openings on the back besides the power connector, 2 DB25 connections and external video. Has anybody seen one of these? I suppose if could be some kind of disk or interface exerciser. Google turns up nothing. Thanks Mike mmcfadden(a)cmh.edu

Core Memory Interfacing?

by ajp166＠bellatlantic.net

Not that many trasistors more like 128 diodes. You would need to know: 1-The switching current for the core: 2-the half select current(related to #1): 3-Time to switch 4-is it a 2d or 3d array(word or bit frame) 5-single sense/inhibit or serperate sense and inhibit lines. Words are driven by the same drivers as an individual bit so that saves parts. Generally there is an array of multiplexed devices to drive the array, for a 64x64 that would likely mean only 128 driver devices (best done as integrated stuff like TI 754xx parts) and a lot of steering diodes. You will need a sense amp per bit and an inhibit driver per bit. Most core systems use a delay line to get the timing as the cycle is RMW (read/modify or rewrite) as core is destructive read out (generally) so you have to write the data back. The time you sense the bit change is tied to the core used and varies some with temperature and current. Also the sense amp must discriminate from noise and a valid pulse related to a bit change. Oh, it will be slow. Most core system were over .5us{500nS} Tacc and Tcy are typically 1.0-1.6us{1000-1600nS} . It's a rewarding task but non-trivial nor small. FYI: you need a heafty low noise multiple voltage power supply to run it. Me, I'm looking at a 16k semiconductor memory replacement for a PDP-8f that is simple. This would be a resource to those that have found an -8 without enough core or to replace bad core. This is of course a IMCFT project.

Still, it's a well-known fact that research causes cancer in > rats :-) ROFL! Theoretically, judging by the amount of solder flux I've inhaled over the past few years, I should be either on my deathbed or have some form of cancer by now... Fact: If I listed every single chemical I've ever exposed myself to, it would probably be long enough such that if I printed it out, it would go to the sun and back... And some of the chemicals on that list: Acetic acid (photographic stopbath) Hydroquinone (photographic developer) God-knows-what (photographic fixer) Acetone (nailvarnish remover) Whatever SRBP board dumps when heated to 180 deg C (toner transfer) Ferric Chloride (PCB etchant) Lead (solder) Rosin (solder flux - Maplin probably don't use it in their lousy "Adepto" solder) Xylene (Electrolube lacquer pen) Mercury (glass tiltswitch) Need I go on? Once again, my philosophy is "Screw it - I'm going to snuff it at some point anyway". And if scraping my fingers (and cutting them) with solderjoints is as bad as breathing in solder fumes, I should REALLY be dead by now...

CP/M and Imsai

by caprio＠dcms.com

Thanks to all for you comments on the S-100 and Imsai. The reason I got intersted in this was back in the late 70's I worked for an OEM and we rolled out data Entry/Retrieval system on Datapoint, Then moved to the Imsai, and then the Intel SBC 8086 running RMX/86. This was my first programming job. Everything was written in assembler and progressed to PL/I then finally forth. I loved this job. Back then programmers appreciated tight code and knew how to save a few bytes of code. It was amazing what we did with the Imsai. I think we had 30+ serial connections to data entry terminals with keypunch operators banging away at 100 WPM! The terminals were also used for data base retrieval over a dedicated line connected to our mainframe, a Xerox Sigma 9. Our mainframe application was written in assembler as welll (MetaSymbol). I also ported a few 8080/z80 applications to 8086. When I left the company ten years later we had piles of Imsai's on pallets and didn't know what to do with them. I bet they ended up in a landfill somewhere! Wish I had just a pallet of them today! It's been twenty years since I worked on the Imsai. Most of my knowledge on these and other S-100 systems is burried in my brian somewhere problem is I can't seem to fetch it :^) At any rate I'm up for the challange and am looking forward to putting my Imsai system together. Any ex employee's of Science Dynamics (Torrance, Ca) out there? Jeff, Neil, Ralph, Dave, and Less are you there? and then

Hmmm... He stayed with my family during a 3-day stop in September 1978... I gave him a 23-channel CB radio to ease the trip out, and he gave me a copy of a Nektar album (it wasn't "Remember the Future"). White and olive drab VW Microbus. >From what I've pieced together, EasyWriter must have gotten started when he got back to the Left Coast. He *might* have started formulating the ideas while in Harrisburg (Harrisville?) State Prison. We corresponded for a while before he went in; I was an early user on WRBBS (Ward and Randy's BBS), and if it wasn't that BBS, it might have been The Well or one of the other Kalifornia BBSs... I contacted Adam Osborne, and asked if he could use his clout to help John out. His reply was that while he didn't necessarily accept the Government's version of what happened, that John was indeed in deep doodoo and anyone that tried to help would get sh*t on their shoes. Now John's doing fine, tho work comes to him slowly, and poor Adam Osborne is slowly dying in a village in India, from Parkinson's Disease. BTW, I'm told that one of Adam's expressed wishes is that he be left to go in peace... Let's all thank him for his efforts and achievements, and wish him a Happy Journey into the hereafter. And please don't take that the wrong way. He was right- my brief association with John led to my departure from my position at the University where I'd hoped to get on full-time... but I bear absolutely no grudge for that. The system just plain sucks. -dq -Douglas Hurst Quebbeman (DougQ at ixsnayamspayIgLou.com) [Call me "Doug"] Surgically excise the pig-latin from my e-mail address in order to reply "The large print giveth, and the small print taketh away." -Tom Waits

UART. The DMIII had D7201 {intel 8274} dual USARTs, not common but useful as it's nearly identical to the Z80 SIO but, intended for 8080/8085/8088/8086 style busses. Allison

The second is a much smaller list, naturally. That would generally exclude much with 386 or higher. '86 was the Z100 series, last of the CP/M-80 machines like Kaypros and Compupro S100 crates. Microvax-I was there and VAXMATE was just around the corner (integrated 286 boxen). It was also a point on the broad 286 peak. The Workstation wars were warming up around then as well, this would lead to Sun, Apollo, DECstations{mips} and later VAXstations. Biggest impression of '86, WYSIWYG printing and Graphical screens making a big surge. Allison

WTT: HP9000/700 system

by thomas＠tstrathmann.de

Hi, I have a HP 9000/700, 50 MHz, 128 MB RAM, 1.x GB SCSI disk. Original HP keyboard and mouse included plus an HP 99784A 19'' monitor. Everything is in good working condition and so far I have had no problems with this system. HP-UX 10.20 is installed, I'll include media if needed (you know, the license is bound to the hardware). I wand to trade for something, dunno, make an offer. You would have to fetch it from northern Germany or send a freight forwarder. Thomas -- Thomas S.

When I aquired my VAX 6310 I signed a paper absolving them of all responsibility for the beast. (Didn't sign one for the TU81+...)

Apple IIe card

by pat＠cart-server.purdueriots.com

I've got a card out of an Apple IIe that has a bunch of 7400 chips on it, a 4-switch dip switch, a 26pin header, and an EPROM with a label that says "GPC" on it. The board also has "GPC" and "519" silk-screened on the comonent side and "Made in Taiwan R.O.C." on the solder side. Google doesnt seem to reveal anything useful. Any ideas what this is?
