Amstrad PPC640 (PSU's Polarity and Amps needed)

by 3sdiarftt02＠sneakemail.com

Hi all, I've just been skimming the archives and while I've spotted a couple of Amstrad PPC640 threads, one of which confirms that you can use a normal 12V power supply, none of them indicate the amps needed nor the polarity. I found one of these units at a swapmeet a month or so ago but it was sans power supply. I'm hoping to get it up and running within a couple of weeks for a demo in an introductory computing class. TIA, Chris J. -------------------------------------- Protect yourself from spam, use http://sneakemail.com

Dec VR320 monitor

by lgwalker＠mts.net

I have a DEC VR320 monitor which I have never been able to get to work on a PC and don't want to spring for an expensive video card that would sync to it. I also have a Dec Rainbow 100+ with a color card that I use with a VR241-A monitor, and a DEC Pro 150. It occurred to me that the RB or the Pro 150 (in mono) might work with the VR320. I don't want to chance blowing something or causing the magic smoke to escape tho. Does anyone have any info on this ? Lawrence lgwalker@ mts.net

VAXserver 3100

by Qstieee＠aol.com

To find DEC MMJ cables, go to http://catalog.blackbox.com/BlackBox/templates/blackbox/search.asp and look for keywords DEC MMJ. You will probably need at male-male MMJ and a female MMJ to DB9/DB25. AS with any serial connection, verify pins (on a DB-25) 2-7 and 3-7 (i.e., make sure terminal/PC is transmitting on one line, DEC VAX is transmitting on the other). I usually do this with a VOM; transmit will be a strong (5-15 VDC) signal; receive may be around 0. Usually you will get a >>> prompt from VAX firmware. It will accept a help command and you can do "show devices", then try "boot dua0:" or some other disk device that's listed (they are 99% devices beginning with "d"). Of course you may get a very first product/CPU ID, then some testing messages. You are hoping that it progresses through the self-tests and gets you to the >>> firmware prompt. Often >>> will take a "help" command too. Often you need to send "delete" and not "backspace." Try 9600/8/N/1 settings. Also probe the Compaq, Montagar, and Process sites. With the VMS hobbyist program you can get going pretty well these days.

Chip Upgrades for 11/23 (was Re: 11/03 system on eBay sold)

On Jan 9, 11:36, Frank Arnold wrote: > I wonder, EIS/FIS chip as well as CIS are basicalley Roms that expand the > microcode control store of the F-11 microprocessor. True? Almost. They are ROMs, but EIS/FIS is for the 11/03 KD11 processor, not the F-11 family. CIS is a set of microcode ROMs for the F-11. There's quite a lot of information in the KDF11 CPU Module User Guide, and probably more in a technical manual. Basically, it seems that the the microcode is stored in a device with two bidirectional 16-bit busses (MIB and CDAL). MIB is a multiplexed bus. Part of the time it outputs the current microinstruction and the rest of the time it receives control signals from the CPU. The CDAL bus (which is actually a 22-bit bus, but only 16 bits are presented to the option sockets) is what eventually connects to the external BDAL bus, but it's also used internally for control signals. -- Pete Peter Turnbull Network Manager University of York

H89, REMark, Sextant

by cdhall＠vt.edu

Folks, I emailed a couple of days ago about the H89 and back issues of REMark and Sextant that I have. I was surprised at the level of interest. Someone suggested I post the items on ebay and I have done that. H89 is at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=1247&item=2087562 690 REMark issues are at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=2243&item=2905394 499 Sextant issues are at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=2243&item=2905396 513 Thank you, Chris ----- Christopher D.

The relevant instructions are built-in on the 11/23 and 11/24 KDF11 processors. The options for the KDF11 are KEF11-BB CIS (dual-width), DC304 MMU chip, and KEF11-AA floating point. -- Pete Peter Turnbull Network Manager University of York
