Hardware Emulation (was Re: Spectrums, Ultrix, feeling old :)

by cmcmanis＠mcmanis.com

One of the 'toys' I recently purchased is an eval board with the Xilinx Spartan II 200K gate FPGA on it. My plans for this are classic computer emulation. (there is already a PDP-8 VHDL description floating around and I'm looking at doing one for the PDP-5, PDP-11, and PDP-12). But this board includes bits that let you drive a VGA display with it if you choose and it has PS/2 ports etc that you can also use. So I figured wouldn't it be cool to actually try doing "new" Atari 2600 hardware or something like that? It should be pretty easy to design a PONG equivalent game, the original was all TTL gates anyway. All I need it another hobby I don't have time for but it helps motivate me to learn the tools if I've got a project to work on. --Chuck

My ZX81 stack wins on this point because they're all in different packaging, except the 2 kits! Can't say the same for Spectrums though, but when someone's got a mint boxed one for a fiver I can never say no!

Please help identify S-100 boards

by r_beaudry＠hotmail.com

Hello all, I just obtained three S-100 boards that I thought were floppy controllers, but on inspection, may be something altogether different. I have no documentation on these boards, so here's the description: All three are marked "DYSAN (c) 1982" Two are marked "Wear Tester Cert. Bd." One is marked "Model V TrackWriter Certifier Sub." All three have 34-pin and 50-pin connectors, and all three look to be the same PCB layout, but with different components present or absent, and slightly different silkscreenings. For example, the two "Wear Tester" boards have ByteDAC chips in two sockets, but the "Model V" has those sockets empty. Most of the other chips on the boards are either standard "74" logic, or Op-Amps, or the aforementioned ByteDAC chips. All three also have a National LH0032CG in a can (don't know if that's significant or not). If anyone can identify these boards, or more importantly provide documentation (including schematics), I would surely appreciate it! I am willing to trade $$$ for information... Thanks! Rich B. P.S. I'm a digest subscriber, so I will not reply immediately if you send to the list....

Collecting and taxes

> Interesting question though -- "should the tax people visit my site they > might think I'm making a living from buying and selling machines" -- what > if the "site" in question is a web site? Can the revenooers use what they > see on a web site against the owner? :-) Web sites currently don't enjoy the protection they should. If you painted a picture of Superman on your bedroom wall, because you like Superman and want people who come to your bedroom to know you like Superman, that's fair use doctrine. If you put a picture of Superman on your web site, and DC Comics sees it, you'll get a cease-and-desist letter from DC lawyers. And if you don't comply, you're in court. That's because the law isn't making distinctions between corporate and personal/private web sites, but it should. My personal home page is a virtual bedroom wall. Enough of that, we're swinging way off topic again. -dq

As far as they're concerned you have about the > same rights that the Jews did in Nazi Germany! Actually, I have. In 1986, when I filed for Chapter 13, they sent me a letter saying I hadn't filed for 1985 and 1986 and owed an estimated $11,000 in back taxes. I wrote back saying, it was true, I hadn't filed for 1985, *yet*, but would do so now as I expected a refund. Additionally, I sent them photocopies of the 1986 filing & refund check they didn't seem to know about. And human engeineering has yet to create the lock that can keep me out of my house.

TI-99/4A

by ajp166＠bellatlantic.net

From: Cameron Kaiser <spectre(a)stockholm.ptloma.edu> >If the TI uses a DSUB-9 connector (I must be the only one here who doesn't >have one), I wonder if the Tomy Tutor joysticks would work. I know TT >joysticks are definitely not Atari compatible -- I nearly killed my C64 with >one (remember that the joystick lines go right into the PLA, the glass jaw >of the C64). Atari joysticks may work with the TI save for connector. The ti joystick is only an array of contacts in PARALLEL with the keyboard contacts and there is no logic inside. A common problem is the TI version of the joysticks have a poor contact life so bad ones are good for the plugs and wires. Allison
