I forward both Ebay and Paypal spoofs to spoof(a)ebay.com or spoof(a)paypal.com. they then check them out and notify me if they are fake or real. A couple of times I have forwarded regular traffic to the spoof notice and got a return email telling me it is not a spoof. I hope this helps them find the source. Paxton Astoria, OR

Santa, for Christmas I would like

by james＠jdfogg.com

Something blue and white and it says Data General on the front. If it says MV it would be even nicer. Does anyone see these anymore? My brother was one of the developers of AOS/VS and I would really like to restore one.

I was always rather disappointed with its speed, though; it's considerably slower than most of the other Indys. I never liked the look of the Indigo^2 so I don't have any of those.

ZX81 denigrated! (was Re: Approaches to projects)

Aside from keyboard ;-) CPU intensive video design - lose video when program running (or SSLLOOWW mode for ZX81). This also makes it highly dependant on the internal firmware, so that it's tough to adapt other Z80 software systems to run on it. "RF only", and poorly shielded computer make it tough to get decent TV display. Limited internal RAM - and expansion very prone to connector problems/flakiness (practically useless without an external keyboard so that you didn't have to touch the machine while it was running). Slightly odd dialect of BASIC. Never did like the use of single-key "shift" keywords (although this is essential given the keyboard) - also a matter of taste, so this cannot be considered a "fault". But... I still consider the ZX80/81 a rather interesting and innovative design, because it truly was designed to get "something from almost nothing". Most of the items listed above are just the "nature of the beast" - given what it was (the lowest price entry on the block) and to be *VERY* cheap to manufacture. I know guys who did a *LOT* with their ZX80 - they are a capable machine. But, their limitations make them look very poor when compared to other more traditional designs. To appreciate the ZX, you need to keep in mind that it is SUPPOSED to be a very minimal machine. It makes more sense as an alternative to a programmable calculator than as an alternative to a word processing or serious software development machine. The only really bad thing about the ZX is that I think a lot of people bought it expecting more than it had to offer...

Can I point out that there are two battery pacs for the TI Programmer (LED version). Battery life with the rechargeable NiCad pac is woeful, about 2 months for me on a charge with modern aftermarket NiCads. The 9V Eveready alkaline battery that has been in the calculator all this year, hasn't died yet. I've had this calculator since new and never had any problems.

ASR-33 / PDP-11 question

by wacarder＠usit.net

Ok, I need to call in the experts. I have had much success lately in getting my PDP-11/34 system hooked up to multiple peripherals, running RSTS/E V7. I have RL02, RK05, multiple VT52s, LA36, VT100 all working running timesharing, terminals all connected via EIA DZ11. I added a 20mA DZ11, which is recognized by RSTS, and it uses 8 more KB numbers, with 8 less "unrecognized devices". The EIA DZ11 uses KB3 through KB10. I have configured the lines that I'm using so that the terminal characteristics are set properly by $TTYSET to match the terminal types when the system starts. The 20mA DZ11 uses KB11 through KB18. I want to connect my ASR-33 to the second terminal connector on the distribution panel, therefore it should be KB12 to RSTS. My problem is that I am now attempting to connect my ASR-33, which works just fine is local mode. I am using phone wire, connecting wires from the DZ11 connectors 1,2,3, and 4 to connectors 3,4,6,and 7 respectively on the ASR33 terminal strip. My info tells me that: DZ11 1 = Receive + = ASR33 7 DZ11 2 = Receive - = ASR33 6 DZ11 3 = Transmit - = ASR33 3 DZ11 4 = Transmit + = ASR33 4 Something must be working right because if the 11/34 is not on and the ASR33 is turned on in "online" mode, it sits there and "clicks" repeatedly. However, it stops this clicking when the 11/34 is powered on. I checked the lines and there is a 20mA +/- current on the lines. The problem is that when I type on the ASR33, it does not echo, and when I use RSTS to send characters to the ASR 33, it does not respond. This ASR33 works perfectly in local mode. Anyone on the list have a clue what's wrong before I dig deeper? Is there something obvious that I've done wrong? The ASR33 is supposed to be working. I have configured the ASR33 on KB12 to 110 baud using $TTYSET, but no luck. Just to be sure, I set all 8 KBs, KB11-KB18 to use ASR33 terminal chracteristics. Help would be much appreciated. Ashley

The one I have is a replacement, but almost identical to the one my Dad bought in the mid-60s. It's about 115mm wide x 55mm thick x 200mm long; it has three DIN sockets on the left-hand side, and a red button for recording, a sort of joystick knob to control the tape motion, and a tiny level meter all on the top front panel. It takes five C-size cells. It originally came with a slightly larger leather carrying case that had space for the microphone and a power pack. Still doing sterling service on a BBC Micro and an Exidy Sorcerer, though it's about as old as their combined ages. -- Pete Peter Turnbull Network Manager University of York
