Along with the additional UYK-20 computers I found some parts of some AN/UYK-44s. I know that they were used similar to the UYK-20s. Does anyone have any detailed info about them? FWIW they also use core memory. I found that they use the Quadri core memory blocks that I was asking about and posted the picture of about two months ago. Picture at: <http://216.239.39.100/search?q=cache:kY3RwZ-3HjUC:www.lockheedmartin.com/se…> One of the parts that I got was the operator/programmer's console.

DEC VT10x and VR201s (was Re: DEC Rainbow)

> > review claimed the VR201 was compatable with the VT102. > > Considering the former is a composite mono monitor and the latter is a > terminal, that's just impossible. I seem to recall that many/most VT100's had composite video out - mine do - and this was frequently used in the classroom to drive a larger monitor, or distributed to several monitors/terminals throughout the classroom. This way my Data Structures professor could show us *exactly* what she was on about. Perhaps there was an adapter to use the VR201 in this manner? I can remember staring at the displays, but not what was rendering them. I know she was working on a VT100, but can't "see" the slaved monitor in memory... --Steve.

But other people use OE without these problems. My mailbox currently contains 47 messages created with OE, including some from at least ten other listmembers, and only yours have the UTF-7 problem(s). Some are version 4.72, some 5, some 5.50, some 6.00, etc. I even found several with exactly the same version you have (5.00.2615.200), so it looks like there's something else in your setup that's making OE prefer UTF-7.

FY Sellam MS OE

by allain＠panix.com

(It means "For You", yes. yes, that's what it means <g>) For those wondering where my bad escape sequences came from, or why, here is a partial explanation. I used to get ISO encoded messages when I originated a message to Classiccmp and UTF-7 encodings ($ = '$', = = '=', _ = '_', etc.)** when I used "Reply". A while back I noticed that sometimes after setting an encoding and sending to the list that the encoding was lost to UTF-7 anyway. This was about the same time as the list software change so back them I assumed incorrectly that the new software was setting UTF-7 headers (Content-Type: text/plain; charset="utf-7") and loosing my ISO ones (...charset="iso-8859-1"). Now it seems that the way the setting was getting lost was by saving and recalling message drafts in MS OExpress. It is very possible that there are other ways MS will mess this up but for now I think it's fixed. FYI here is my file entry on the subject. "List of Encoding Problems with Outlook Express: You can't shut off charset encoding. (Two choices: MIME and UUEncode. There is a "MIME: encode text using None" option which doesn't work, it still encodes.) You can't set an encoding 'for once and for all'. There is no clear indicator of the encoding in use (have to go down two menus to check/set each message). Selecting a useful encoding [Western European (ISO)] results in display using an undesirable proportional width font. Manually selected encodings are easily lost and overridden to UTF-7 (example: set ISO, save as Draft, recall, send, it will be UTF-7**) The appearance of an encoding is buggy; what appears when reviewing a saved message is sometimes decoded, sometimes not, with the same message. Can't check a message header on an unsent message." so Sellam aggravation is nothing compared to this <g> If somebody wants to help, why is one of my messages today (Sunday, November 03, 2002) 1:07 PM, BBS..., about Panix, appearing as proportoional font and 1:53 PM, about vcfban.gif, appearing as fixed width font, to me anyway. MS-UGH! John A. ** hope this displays correctly, the sequences will probably be lost.

It's not just the quotes or whatever is being used to indent the quoted text. It's anything that isn't flat 7-bit ASCII, with some characters reserved to allow encoding. For example, the line > +ACo- +ACI-Data Explorer, from the IBM +AF8-Deep Computing Institute+AF8AIg- contains 4 different escape sequences, one of which is 8 characters long! UTF-7 is a coding system designed to handle Unicode (which is normally 16-bit or 20-bit) by using escape sequences to encode non-ASCII characters in a way similar to the scheme base64 uses for whole chunks, and intended only for use on 7-bit systems that can't handle 8-bit data. > OE 5 has several choices for indent on replies... I am using '> '. If John is > using ': ' or '| ', (the other 2 choices), they might be getting read as > something else by your MUA, and changing the indent might eliminate the problem. > What MUA's are you guys running? The text appears with the wierd escape sequences on loads of MUAs, in fact probably most of them. Very few MUAs support UTF-7, because it has inefficient compression, there are other encodings that are more versatile, it's more awkward than most to program, and it's a one-to-many transform (for any given string, there are several possible encodings) so it produces unsearchable text. And since it came along later than the other common encoding schemes, and doesn't do anything the others can't, I suppose there was an element of "why bother?" If you look up Unicode and UTF-8, you'll find dozens of common applications that support it (and UTF-8 is the accepted standard for a whole load of things defined in RFCs, as well as the mail internationalization report >from the IMC) but the only application I know of that definitely handles UTF-7 is Outlook. Quote from the IMC report: "Fortunately, very few vendors implemented UTF-7, and its use is strongly discouraged in Internet mail." The solution is to turn off the UTF-7 character set, use ISO-8859-1 or UTF-8 or something else that's commonly accepted, and then use a standard content-transfer encoding, like quoted-printable or base64 if you have to make it 7-bit-safe. -- Pete Peter Turnbull Network Manager University of York

Some more info on the Philips P3800, and P4500

by julesrichardsonuk＠yahoo.co.uk

Will, > I came across a site today which provided more information on this critter, > and as Fritz had suggested, it is indeed a TurboDOS machine.. I have a copy > of TurboDOS around, but I don't know if Philips used a custom version or ? no idea on the data front. Did TurboDOS have built in multi-user support (I know nothing about it)? If not then I'd definitely think that the version on this machine was custom, as it has support for at least 4 if not 5 terminals in its current state. That's just going by the cables at the back; there's a lot of unused pins on the card edge connectors, so given that the website claims support for 62 terminals I expect it could make use of some breakout box arrangment to give more 25-pin terminal connectors. > Not to mention that I don't have a clue how I'd copy it, or even what > TurboDOS runs on. Here's the link I found to the info on the P3800: > http://www.digidome.nl/philips1.htm unfortunately I hit a bit of a snag with my machine. Following the flood damage the previous owner had tried to fix the system. Trouble was, the machine has two backplanes to it - the upper one with one row of card sockets and the lower one with two rows. System cards from the top rack will also plug into the bottom rack (which contains the PSU, mains voltage, and a spare slot for some unknown board). The disk controller had been plugged into that spare slot... :-( It wouldn't have got any mains voltages but it would have got +5 and +12V on all sorts of pins that it shouldn't have. I also found that the disk data bus (SCSI? SASI?) terminators had been misaligned and so it's possible some of the data lines were shorted together or at least had a low resistance connected across them. Curiously, the disk controller and the board the converts the system's SCSI/SASI bus to MFM look to be identical on the P3500 (from the photos on the website that Fritz posted about). So if one of those ever shows up, at the very least it'd be invaluable for checking that the hard drive on this 3800 is still operational - and in the absence of schematics for the 3800 it'd probably be very useful for fixing the 3800's disk controller. > Also, the P4500 is a minicomputer of some kind, apparently.. I'm not sure - I did a quick hunt on the web and there was very little information around. One site seemed to imply that it was much older technology than the 3800, but another site gave the impression it was much newer. Uless the model number was reused they can't both be right :) cheers Jules __________________________________________________ Do You Yahoo!?

I show a lot of respect for CRTs when handling them! I had to remove the deadly-looking bare PSU mounted on the drive enclosure in order to work on the drives, so it also got the kid-glove treatment . . . What I meant by gotchas was: anything troublesome about the serial or parallel i/o? Any known bugs in the ROM? The manual very nicely documents the ROM routines (if the book is accurate) so this thing should be fun to do some assembler programming on. So far, despite all I've heard about "trash 80," this system looks pretty friendly. Later -- Glen 0/0
