The position is always relevant, but you don't set it to AC. You set it to MD (Memory Data). And when you press EXAM (or DEP), the address displayed on the upper row will increment (but the data displayed will remain the same, the data for the address that was current when you pressed EXAM/DEP). > The answer seems easy, I just want to hear confirmation. > The current implementation shows the contents briefly after I > pressed EXAM *and* the knob is on "AC".

one more question about pdp8/e console switches behaviour

by GOOI＠oce.nl

Hello all, I have the pdp8/e *including* the console running on the Core 6809 Board (plus one I/O Board)! But ... I have one more question about the behaviour of the pdp8/e. If the HALT (or SING STEP) switch is down, you can use the EXAM and DEP momentary switches. If I press EXAM, I want to see the 12-bit word contents of the address currently on display in the top row (memory address) of the console. That 12-bit word is displayed on the 12 lights below the memory address lights. Is it correct that the position of the selector switch (the rotary knob) must be on "AC" to see the contents of the active address? Or is its position not relevant while HALT (or SING STEP) is active which seems odd to me because you want to be able to see more than just the AC when you HALTed the CPU? The answer seems easy, I just want to hear confirmation. The current implementation shows the contents briefly after I pressed EXAM *and* the knob is on "AC". Just *very briefly*, then the simulation shows the actual AC content again. So, on a real pdp8/e I assume that when the knob is on "AC" you see the contents of AC when HALT is active? In that case, after the user pushed EXAM once (and the memory contents is displayed as I described above), how does he get to see contents of the "AC" again? Hope I made myself clear why I asked the question ... TIA, - Henk, PA8PDP.

Macintosh Plus 1MB with kybd., mouse, cables, cover(s) Free for Postag e

by wpileggi＠juno.com

A Macintosh Plus 1MB with keyboard, mouse, power cable, apple cable and dust cover(s) followed me home from trash night. I powered it up - makes the tone, then wants you to load floppy disk in drive. I've got no boot disks... Display is good. Overall condition is decent, needs cleaning. Weights 20 pounds/9Kg. total. It's yours for postage from 19001 USPS; 19044 UPS; 19034 Fedex. In case you're interested, they threw out the Apple printer last week - someone else picked it up. I got the HP laser printer though last week....strangely enough, they threw out another HP laser printer tonight, this time with a toner cartridge. The toner cartridge is bad...rats...Bill. ________________________________________________________________ Juno Platinum $9.95. Juno SpeedBand $14.95. Sign up for Juno Today at http://www.juno.com!

Almost vintage...

by news＠computercollector.com

I'm looking for a copy of AutoCAD 12 for DOS -- circa mid-1990s. Can someone perhaps copy the disks onto a CD for me (please)...? Of course, I'll pay for the CD and mailing. I don't need any documentation.

Toshiba T4400 password

by liste＠artware.qc.ca

At "Au Vieux PC" (where shopping is always an Adventure) I spotted a T4400 with docking station and parallele port to SCSI addapter and other bits. All for 15 CAD. However, the T4400 has a BIOS password. http://www.bitlink.ca/Library/toshiba.shtml Says that it's impossible to remove the password. Anyone here have any other ideas? Also, anyone want this beast? -Philip

Hello, I need a bit of help. I had a problem with my ISP and my mailbox got shut down for three days. After this, I am having problems getting my daily messages for either cctalk or cctech.

If someone might be able to help, please respond to my email. Please feel free to forward this to the appropriate admin for resolution. Thank you for any help you can provide, Kurt

PDP-11 Stuff In Michigan

by ohh＠drizzle.com

Hey, here's a couple of posts from alt.sys.pdp11 for those who have an interest: the first a list of equipment, the second some additional information about their current situation. Sounds like a potentially nice bunch o' stuff. No affiliation, and Michigan's about 2000 miles out of my way. :) -O.- -- first forwarded message -- From: Todd Wilson <wilsonto(a)msu.edu> Newsgroups: alt.sys.pdp11 Subject: Parts Date: Tue, 09 Nov 2004 14:37:03 -0500 Message-ID: <cmr69e$27er$1(a)msunews.cl.msu.edu> Greetings from Michigan State University I've got the following group of stuff set to go to salvage and have no idea of the value (if any) that they have anymore.

Todd Wilson HVAC Services - Michigan State University -- second forwarded message -- From: Todd Wilson <wilsonto(a)msu.edu> Newsgroups: alt.sys.pdp11 Subject: Re: Parts Date: Wed, 10 Nov 2004 07:05:27 -0500 Message-ID: <cmt06p$npl$1(a)msunews.cl.msu.edu> I should clarify... These systems are to be sent to salvage complete, and I don't intend to part them out. Of the miscellaneous parts, the H3104s go with the PDPs (2 with the 11/83, 1 with the 11/93). The MAUs and NI cables were a DECNet interface between the two PDPs. 232-MMJ adapters, I have a bunch of generics (bought from Black-Box) along with the actual DEC ones listed. I also have quite a bit of documentation with the PDPs. The VaxStation was procured as a parts machine since it is also QBus and PDP parts were becoming scarce(though we never used it as such). My hope is to generate some interest in them so that someone will buy them through salvage rather than sending them to the crusher. The last unit I sent to salvage was an 11/24, 5 full enclosures, 9 RA-81 disk drives, 1 RA-80, 2 RLO2, and about (literally) 30 RLO2 Pacs. All were crushed due to lack of interest. When I send this group of items to salvage, it will include some LA100 and 120 printers and stands, an RLO2 Diagnostic Pac (RSX11M), and I think I have 2 or three more VTs (if memory serves, VT320s). I might have 1 more RA80 also. My intent is to post back here with details on how to purchase the items through salvage when I send them (within the next week or two). Many have offered EBay as an option, but our equipment transfer rules do not permit direct sale of University owned items. All inventoried materials must be transferred to Salvage for release from the University. If anyone need to contact me about them, I can be reached at Direct Line: (517)432-0533 Email: tdwilson(a)pplant.msu.edu Thanks Todd Wilson
