Monitor for iSBC 8024

by richard＠idcomm.com

I've not yet found a board-resident monitor for the Intel iSBC 8024 board. I've got a number of these on hand and have used sadly inadequate resources that worked (barely) for what I've been doing with them, but would like to make it worthwhile writing a set of test scripts for my notebook funcitoning as a terminal attached to the iSBC 8024. This board is a Multibus-I type with an 8085, 8251, 8253, 8259, and a pair of 8255's. Intel shipped a monitor prom which I turned over to a customer many years ago, thinking I'd never need it again ... <sigh> ... I guess you never know. I suppose I could always resort to writing my own, but then I'd be unable to used someone else's doc's, and I'd hate to have to reinvent the wheel just for the half-dozen or so of these boards I have left.

More Free PDP-11 stuff in the UK

by mrbill＠mrbill.net

More PDP-11 stuff available in the UK... Please respond directly to the gentleman below instead of me... bill ----- Forwarded message from Dominic <dominic(a)altoona.fsnet.co.uk> ----- From: "Dominic" <dominic(a)altoona.fsnet.co.uk> To: <mrbill(a)pdp11.org> Subject: PDP11 Computers Date: Sat, 28 Oct 2000 19:02:54 +0100 Hi ! I recently rescued alot of computer stuff from a breaker here in the UK. Everything that was there I took away. The load has some PDP11 bits: 1 x PDP11/73 Model 1730A-B3 SER No. AY00934 1 x PDP11 Model 11A23-R SER No. AY07507 Both are 120/240 Volts AC in on power supply, both units are complete except they are both missing the plastic cases. They were removed ready for the units to be pulled apart, Luckly I got there when I did, BUT some others were not so lucky and were already in bits. I managed to collect: PCB BOARDS: M7555 x2 M8043 x2 M7954 x1 M8049 x1 Also a "Realtime Clock" card ???! There are also large boards: M8067 x4 M8189 x2 Misc Bits: 1 x Rx50 -AA revc Dual 5 1/4" Floppy drive 3 x AA12B1 ASTEC power supply units, Digital code H7864A 1 x Digital VDU inc keyboard type VT320 2 x RS232 cables to connect VDU to 'Console' skt on computers. Both the PDP computers work, the 11/73 boots up ok on its RD52A Hard Drive, runs through a mass of loading commands then says 'Have a good afternoon'! rebooting it gets it to request a login and password. I have not managed to get in despite several attempts. The other goes through its startup routine, then asks for a boot disk. I returned to the breaker and tried to find some but was told all disks had been thrown away - typical! The unit has a hard drive but its labelled 'Cleared by Digital' so there is probably nothing on it anyway. It's so sad when gear goes for scrap, even working stuff - such a waste. I am based in the UK in Norfolk near LOWESTOFT on the EAST COAST. I don't know where you are but if anybody wants these items they can have them, no money required! Happy Christmas! Dominic. ----- End forwarded message ----- -- Bill Bradford mrbill(a)mrbill.net Austin, TX

INS8154 used in Cytospin

by ajp166＠bellatlantic.net

The INS8154 is a programable parallel IO device and 128 byte ram. There are no substutes I know of, as it was single sourced from National Semi. the alternate would be to try and find new unused old stack or make a substitute using TTL and ram devices that are avaiable. I know the device though, I have two I bought for use 20 years ago.

HP 125

by Innfogra＠aol.com

In a message dated 10/27/00 5:46:42 PM Pacific Daylight Time, rigdonj(a)intellistar.net writes: > Hey, I have one of those. It's the same shape and size as a HP 9816. > It's a great little CPM machine. Don M. has a lot of software for it and I > have some of the SW. Somebody has got to save this one! Joe; You are thinking of the 120, that is the one that looks like the HP 9816. The 125 looks like a terminal on a square goose neck. The 125 is a great CPM computer. However it uses it's own keyboard which I don't think goes with anything else. I hope the keyboard is there. I also think it uses drives with the large HP connector that looks like a centronics. I am not sure if it has HPIB. I think it came before HP standardized on HPIB. I used to have one many years ago. Paxton

Was it 110, 135, then 300?

by xds_sigma7＠hotmail.com

OK, according to "Technical Aspects of Data Communication," John McNamara, Copyright 1977 by Digital Equipment Corporation, these are speeds for asynchronous communications (doesn't seem to have a sync table): Five bit: 45.45 50 56.86 74.2 75 91 Six bit: 45.45 48 49.1 55.21 56.75 56.86 60.6 66.67 69.25 74.2 80 135 Seven bit: 45.45 56.75 61.35 67.34 74.2 75 76.92 100 134.5 <- IBM 1050, 2740, 2741 std. speed (selectric-based terms) 600 Eight bit: 45.45 56.75 67.58 73.33 74.07 74.1 74.2 84.61 100 110 135 150 165 Model 37 TTY for Western Union then 300 up to 9600 For stop bits, the book lists 1, 1.42, 1.5, and 2. The difference stop bits are what make for such weird numbers, though some modems have even more bizzare rates, such as 200 (top speed of British Post Office Datel 200 service), and 1800 (top speed of Bell 20-type modems).

Tango Schematic capture, PCB layout and autorouting programs

by rigdonj＠intellistar.net

I was in a library book sale store yesterday and found the complete packages for Tango Schematic (schematic capture program), Tango Route Plus (autorouting program) and Tango PCB Plus (PCB layout program). These date >from about 1991. Has anyone used them? Are they any good? I was out of money so I went back early today to pick them but someone had taken the Tango Schematic. The funny thing is that all three were in a box together and they didn't take the other two. What's nore, they require a dongle and the dongle was in the Tango Route package so they can't even run the Schematic program. I went ahead and got the other two programs. Has anyone got a copy of Tango Schematic that they're willing to part with? Why was I out of money? Because they also had "Bit-Slice Design: Controllers and ALUs" by White and "Bit-Slice Microprocessor Design" by Mick and Brick and some other GOOD books and I spent my money on those first. FWIW both of these bit slice books are VERY good and very easy to understand. I highly recommend them. One of my other COOL finds there was a September 1977 issue of Scientific American. It's filled with articles about microelectronics (almost completely computers). There's also a LOT of ads from the various S-100 computer manufactures. BUT the coolest thing in it is an article (Microelectronics and the Personal Computer) by Alan Kay. Alan was one of the guiding lights at XEROX PARC. This article has a pile of pictures and information about XEROX's then experimental graphical computers. It even mentions a new pointing device called a mouse. Does anyone know what that might be? :-) Joe

It's listed in the Hardware Manual (and mentioned no a couple of web sites). You connect a terminal (or PC or Mac) to the serial port (VT100, 9600 baud, 8N1), set the Ethernet switch to "test", power the GatorBox, and you should get a menu. Select the code memory test, which wipes all the settings. However, you will need to re-install the GatorShare software afterwards, which will require a Mac and a "download server" (could be a TFTP server). -- Pete Peter Turnbull Dept. of Computer Science University of York

Now, I've set the SCSI ID to 1. I also noticed that the parity generation was disabled, so I enabled it.

Q: Third-Party Unibus Memory Boards

by mcquiggi＠sfu.ca

Hi Gang: This morning I was sorting through a bunch of my spare Unibus cards, and noted that I have at least half a dozen RAM boards. These are all, to my knowledge, Unibus cards. These are not documented in the DEC Field Guide (thanks to Megan for her diligence in keeping it relatively current). In the short term I'd like to find out the characteristics of these cards, and their compatibility, in the longer term these 3rd party cards should be added to the Guide. Here's what I know: 1. Plessey Peripherals 705075-100 Rev B. Hex height card. 2. Standard Memories MM-140 PD Rev C4, also marked 102415-442 and stamped "20272" in large (3/8") white letters. Also a hex card. I have about 5 of the former, and 3-4 of the latter. My motivation for this exercise is to find a card that I can use to swap out the 128 KW RAM board on my (sick) 11/34A. This card is a M7891-DB, 128 KW 18 bit parity RAM. If either of these cards are similar in config (size < 128KW is irrelevant as I just want to see if I can get the machine to boot) then great, otherwise at least I can label the boards, and ask Megan to add them to the Field Guide. Thanks, Kevin -- Kevin McQuiggin VE7ZD mcquiggi(a)sfu.ca ---------- To unsubscribe (or subscribe) from (to) this list, send a message to info-pdp11-request(a)village.org, with the first line of the message body being "unsubscribe" or "subscribe", respectively (without the quotes).

PET keyboard

Sorry I can't help the one I have is a chicklet type. I actually had it for about two years before I found out it was a PET keyboard.

IBM P70

by SUPRDAVE＠aol.com

--speaking of P70s and such-- I've v3.0 running on the P70 and would recommend it. There was lots of fixpacks for v 2.x I've never had trouble installing OS/2 on PS/2s. They are made for each other. Probably some of the easiest installs I've had. If you can find warp connect, install that as it's more up to date than v.3 or at least install blue box version 3 and run as much memory as you can.

Mac TCP/IP networking (was Re: old MAC's)

I have a GatorBox CS (you can still get software updates from Cayman's FTP site), and although I've never tried this, it is supposed to be able to allow Unix machines (or other machines that talk TCP/IP) to print to Laserwriters on the Localtalk bus. We used to have two at work which allowed Mac users to use our Unix printers and Unix/NFS filestore (which suggests it does translate properly in both directions). They also allowed our Macs to talk to others on the campus, which involved going through at least two IP routers and the ATM network as well as the two ethernet segments and GatorBoxes, though I think that used some sort of tunnelling mechanism. And of course all the Macs, PCs, and Unix machiners could ping and telnet to each other, though I'm not sure how much of that involved the GatorBoxes and how much was done by software in the Macs. We no longer have/use the GatorBoxes at work, though two other Departments still do, I believe. Our Mac users use Dave to talk to the print servers and file servers. I don't know much about it, but I think it's a sort of Samba client -- doubtless some of the Mac users on the list know much more than I. -- Pete Peter Turnbull Dept. of Computer Science University of York

DEC RP06 power

From: Richard W. Schauer <rws(a)enteract.com> >I've recently acquired an RP06 as part of a PDP-11/44 system, and I wish >to run it (why not?) I remember reading on this list a while back, that >it could be operated on single-phase power instead of three-phase. I got >a printset along with the drive, and it's pretty unclear about what would >use the three-phase- it's almost like the third phase is ignored, the 208v >between the first two phases is fed to the transformer, and the primary is >sort-of center tapped to feed the 115 volt fans. Is this right? How >would I go about feeding it single-phase if that isn't right? Rewire. The reason most of these devices use three phase is to distribute a load more uniformly over what was a normal power system in computer rooms then. Also many of these devices have a rather harsh startup current and slicing it two or three ways makes it much easier for the sytem (wiring and power circuits) to sustain. For example a lowly MVII in a BA23 has a startup surge of over 100A for one cycle (about 16mS). In the second 16mS that might be only 12A and by the 10th your near nominal of say 3.2A. If you turned ten of them on at the same time and same circuit the running current is maybe 32-40A but the starting current could easily exceed 1000A for several cycles. Why? If they were all on one breaker the whole load would attempt to bring the caps in the power supply up that first 16mS... save for the 10,000A surge would pull the 115v down to say 60V (assuming thick wires and the fuses held!) the next cycle would be needed to charge those caps more, likely 10 or 15 cycles so the huge current would take longer to dissapate. Add motors like the RP06 with their nasty starting currents and you see why power systems were so robust. Granted the startup condition is pathological as no one would do that (staggered is also common) but the need to distribute the sustained load is also important. If I had a 6000, I'd ahve rewired it already and could tell. Most often (but not always) three phase power is used as independant legs. Exceptions would be beasties like VAX9000, PDP10s and other power hungry older machines. Allison

They all have limitations, and it's a long time since I used any of them, but if you want to contact me off-list, maybe we can compare notes and get something going.

I've had great luck with Netatalk (except for having to reboot the Linux box all the time when making network changes). When it's running, it runs well. I happen to have this ancient Appletalk card - DB9 connector and all. I remember researching it a couple of years ago and there was some interest in Linux drivers.

old MAC's

by richard＠idcomm.com

I've begun to see numbers of old Mac's in the various thrift stores. Which models are particularly interesting? I've never had much of a taste for the things, but at $6-$10 each it might be worth snagging the things just for the disk drives, or some such. Today I ran into a classic, a ii-lc or some such and iii-si or something like that. These latter are both those recent-looking low-profile thingies. Do they have anything of interest in them? Dick
