Hello, all: Does anyone have info on a Teletek SBC-1 Z80-based single-board computer? Copyright is 1981. It's loaded except for RAM (from what I can see). It has a Z80 CPU, PIO, SIO, and CTC. There are a couple of blank sockets, and a TMM2016P-2 memory chip (a 2716??). It appears to be built on a S-100 card. Thanks!

The Wang patent relates to videotex terminals, exactly the stuff that British Telecom developed in the 1970s and pushed hard (as PRESTEL) in the early 80s. Prestel was organised a little like an ISP, with various "IP"s (information providers) renting space in which they creating "frames" of text and (chunky) graphics which were accessible by modem. IPs could sublet space, too, so individuals could rent just a single frame if they wanted. In 1982 PRESTEL launched a service called Micronet800, which used thousands of pages on PRESTEL servers to store microcomputer related news, software, etc, and started selling software to enable home micros to dial up and display/load/save these pages. Actually, stuff for micros had been around on PRESTEL before that, but spring 1982 was when it took off. I got my software and modem that summer. Most of the modems were simple devices built in to an acoustic coupler, fondly known as agnostic complicators. PRESTEL itself didn't make use of file extensions, but obviously some of the micro systesm that accessed it did. CP/M has always based certain actions on file types and extensions, for example. It did use menus of links, and the links between frames, could be quite arbitrary (and tangled!) just like the web. There was even a command to go back one or more frames, and there were "response" frames and a mail system and ... -- Pete Peter Turnbull Dept. of Computer Science University of York

As far as commonality of old machines goes, most airports have old machines. Public libraries do as well. The boston public library just replaced some Vaxen with Alpha machines. I couldn't get them to tell me what they did with the old stuff. In general, I would say that the amount of old machines is greater than a given reasonable estimate (ie there's always one more).

But you can't easily use both sets of registers at the same time (yes, I know we sometimes do, but it's a fiddle) and the Z80 is very much a single-accumulator type of beast. And as for IX and IY ;-) The original design of the 6502, incidentally, was that all of zero-page be treated as registers. They just happen to be external to the chip, which wasn't completely unknown elsewhere in those days. So in that sense it is possibly the most register-rich design of the era -- but the registers are hardly general-purpose, and the 6502 is also a single-accumulator design. > On the instructions RISC systems of the time and even later didn't have > the addressing modes and often had a distinct register load and store > instruction.

Quite a different philosophy to the Z80, in many ways, but I like them both. We used to say that you had to learn how to use the 6502, and when you did, the code was neat, but on a Z80, you just had to decide what you wanted an instruction to do, and then pick the one that did that.

Well, whether I think that's sensible or not ('cos I think you ought to be able to copy a null string), if ANSI says it's undefined, then it's not a bug. I take it back.

A NUL string would be a string with a single ASCII NUL character in it -- and rather hard to manipulate in C, since NULs mark the ends. Nevertheless, they do exist, though that wasn't what I was talking about. -- Pete Peter Turnbull Dept. of Computer Science University of York

Yes, I should perhaps have mentioned mailing to postmaster@... or abuse@... as several responsible ISPs do follow these things up. I've had two very positive responses from sysadmins, one of whom tracked a spammer who was spoofing via his system, and one from a large ISP. In both cases, the culprit lost their account. It's worth looking at all the "Received: from ..." headers in such cases. -- Pete Peter Turnbull Dept. of Computer Science University of York
