Thanks I'd like one too, but I have in mind integrating it with the Re: Toilett processing (Was: ZX-TEAM meeting and Webcam) thread in some creative fashion... ;)

VT-320 Hack+Tip for Smokers

LK401 roolz! >The LK250 however is a TOTALLY different animal and uses >different keycoding to be compatable with PCs or VAXmate >(a sorta PC). There are several different cordsets for this one. Perhaps I can make up by offering a pointer to the VAXmate Tech Ref V1 at: http://208.190.133.201/decimages/moremanuals.htm This includes a description of the LK250 in Chapter 8. The LK201 is described in some detail in EK-104AA-TM-001 VCB02 Video Subsystem Technical Manual (see Appendix B for the LK201 and Appendix C for the Mouse) which is available at the same location. It is also described in the PC100 Technical Reference Manual, which I'll send over when I get a round tuit (same goes for the LK201 printset). Antonio

Not as easy as you might think. You want it to flush when you get up, but not when you sit down, or when the seat is unoccupied . . . > now how do you tell if the ROLL is > almost empty ? This one *is* easy: the holder must be spring-loaded. As the amount of paper on the roll decreases, and the roll becomes lighter, the roll and holder will be pulled toward the spring, eventually closing a micro switch ;>) Glen 0/0

MSCP Initialization

by chd_1＠nktelco.net

I am trying to get a KFQSA to work with 2.11BSD on a pdp-11. It always fails with an error in the SA register during the transition between STEP 3 and STEP 4 of the initialization sequence. The SA register ends up with the value 101513. The error bit is set and I think that the rest is an error code. I can't find a reference to describe these error codes. An RQDX3 and a CQD-223 in the same machine initialize fine. The KFQSA initializes in an MVIII using NetBSD 1.5. I have looked over the initialization code from NetBSD, Ultrix-32, 4.4BSD, Ultrix-11, and 2.11BSD. The values being sent, are all very similar. One difference is that the VAXen OS use polling during the init, and the pdp-11 code uses interrupts. Any suggestions or comments about the MSCP 4 step init and how it works on the KFQSA? A pointer to error code reference would be great too. -chuck

Wright Punch up for auction

by brian＠quarterbyte.com

There's a Wright Punch up for auction at www.govliquidation.com. The Wright Punch is a cool little manual hollerith card keypunch machine. Someone ought to get it! It slipped by me -- auction closes at 8 PM eastern time, that's less than an hour from now. Sealed Bid sale, $35 min. The downside is you have to pick it up in Norfolk, VA next week, and take a big pile of other junk along with it. You'll need a pickup. If you're interested it's event 623, lot 46, item 37. http://www.govliquidation.com/auction/view?auctionId=25154 Brian =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- _| _| _| Brian Knittel / Quarterbyte Systems, Inc. _| _| _| Tel: 1-510-559-7930 Fax: 1-510-525-6889 _| _| _| Email: brian(a)quarterbyte.com _| _| _| http://www.quarterbyte.com

I was just illustrating that you have to be careful with unattended operations, and not do anything dangerous unless you're sure you're in the right place (or other prerequisites have been met). -- Pete Peter Turnbull Network Manager University of York

I don't have either the service manual or my ZX81 handy, so I can't check, but as far as I remember, just remove the 4118 and replace with a 6116. There might be a wire link to change (if so, it's obvious) but I don't remember having to do that. It is good practice to fit a socket, though. A few ZX81's had a pair of 2114's instead of the normal 4118, which were in short supply at one time, but the same principle applies (the PCB is the same). -- Pete Peter Turnbull Network Manager University of York
