I think if you consider the 5100 a portable, then so should you consider the PDP-8. The 5100, while more *convenient* to move, perhaps, than, say, an Altair, is hardly all that portable. It's listed as 50lbs (a stretch even for me) and has no handle. You tell me how that's a portable? (It's much like a TRS-80 Model III, only flatter. I think the III is lighter though.) I vote for the STM Baby. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

>those "encryption standards" last summer.... wiped out any chance of brain >activity in DC, outside of businesses.... Was there any brain activity before that? 8^) Well, one thing that is often forgotten is that the internet (or arpanet or something) was developed so that the US DOD could have a computer network that wouldn't die if one node when down. Which, of course, can be used against the feds, should they try and censor things. There's no reason I couldn't set up a server in a closet which, at a special, pre-arranged time, would call a server in, say, Portland to pick up the mail that was collected by calling a server in vancouver, etc. (Anyone ever heard of Fido?) Unfortunately, we (in the US) would lose a lot of what has made the 'net indispensable for a lot of people. Singapore censors stuff coming in via the mail (dunno about the 'net); we might very well end up the same way, if they really screw things up (cut off from the freedom-loving world.) --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

Upcoming PBS special on bit rot

by pvhp＠forte.com

Hi, I saw an advert in the latest issue of Scientific American for an upcoming special about archiving digital data to appear on PBS. It is supposed to show on the 13th (tomorrow) and alas I don't have the magazine with me here and I cannot recall what the show title is - or even whether it is part of a regular series. At any rate I thought folks on this list would be interested so go out and check your local listings. Peter Prymmer

help with TRS-80 Model II?

by rws＠ais.net

Hi everybody. First off, let me ask- does anyone else have a Model II? I've been working on mine recently and I can't get it to work. When I got it the CRT was loose and rattling around the case and the power and reset switches were broken apart. I got these things sorted out and powered it up to get a screen filled with hash. It seems to roll around the screen and no characters are visible, just hash. I put a test clip on the Z80 and found very little activity. The only pin toggling is the clock. All of the address, data, and most of the control bus lines and either low or (apparently) tri-stated. I checked the BUSRQ* line to see if maybe something was asking for the bus and it was high. The BUSAK* output is low, however. Shorting NMI* to ground has no effect whatsoever. After it's been on for a while, turned off and right back on again, the screen remains blank. I changed out the Z80 for a known good one with no effect. I happened to note, however, that the computer generates lots of TVI, and the pattern changes during reset. If anyone has any suggestions, they would be most welcome. Also, if anyone has any schematics for this thing, that would help too. (Alternatively, if you know that a certain part is the same as the Model I, III, or 4, let me know as I have the schematics and working examples of these.) Richard Schauer rws(a)ais.net
