I do not suppose that this identity flag can be permanently stored anywhere other than in the firmware flash ROM. I'm sure DEC wouldn't want people to suddenly discover that their machine shape-shifts when the NVRAM battery is disconnected. So does this console test actually erase and reprogram a sector in the firmware flash ROM, or is the change only in effect until the next power cycle? MS

I use an O2 at work, and it's generally pretty good -- but some versions of Netscape are definitely "less good" than others. It's worth trying to get a recent version, or as an alternative, I think some versions of Mozila do pretty well. Make sure the O2 has plenty of memory. Adding 128MB made a huge difference to mine. > > I think I'll now run the browser on my Linux box and retarget it to the > > SGI's desktop (at least until I get an Octane). > > I'll wait to get an Onyx. Actually, the Origin 2000s are quite lovely, > too. They're still really off topic for this list. Yes, though so is an O2, really. Actually, an Origin2000 won't run Netscape much better than an O2 unless there's quite a discrepancy in the processors. My Origin2000 (8 x R10K @ 180MHz) can be outdone (for Netscape) by a fast R10K O2. And of course most O2000s have no display. But if I use an old Indigo Elan for the display, it speeds up dramatically, compared to using other displays. -- Pete Peter Turnbull Network Manager University of York

Development is done on my V4.5 box.. Shitty thing is, that I probably will also have to run a 4.2 system as a second-step system for bootstrapping, and I dont have a 4.2/vax tk50 or cd set. --f

About Electronics Questions

by jss＠subatomix.com

With Tony et al as my inspiration, I have recently started to learn electronics. I've been at it a couple of days, and tonight I just had the "aha!" for how high-pass and low-pass filters work. I haven't come across anything yet that has me completely stumped, but if I do, is it appropriate to ask newbie questions about electronics here? I'm supposed to *answer* questions like that, but I just don't know. Typically, I call electronics conversations as on-topic because they are directly relevant to operating classic computers. Newbie questions, however, are more indirect. For another example, we'll help someone with a Windows program that somehow makes his/her classiccmp go, but I doubt we'll bother to teach a person in-list how to double-click. Is electronics any different? -- Jeffrey Sharp

To be honest, if I found a Lisa 1 for 10 bucks I wouldn't accept $1,000 for it.. I'd sell if for maybe a couple hundred, or preferably trade it for car parts/minicomputers/etc. I really wouldn't feel right about getting $1,000 >from another collector for something I got for so little... Now a reseller on the other hand...

T&B Ansley IDC connectors

by Charles＠socketcom.com

Unless you can find some new old stock you may be out of luck. CW Industries makes the IDCs in the same style but are darker blue than T&B Ansley. See: http://www.cwind.com/ DigiKey lists them in catalog B022 on page 18. I have one, unused 25-pin D female connector with strain relief that you are welcome to. -----Original Message----- From: Jeffrey H. Ingber [mailto:jingber@ix.netcom.com] Sent: Friday, January 17, 2003 4:17 PM To: cctalk(a)classiccmp.org Subject: T&B Ansley IDC connectors Does anyone know where I can aquire the T&B ansley "light blue" IDC ribbon cable connectors that were used by MITS? Googling reveals that Tyco purchased this line of connectors in 2001, but I can't find any mention of T&B Ansley on their web site. Thanks, Jeff

OT: Maxtor drive goes under

by bones＠northrock.bm

Interesting problem. I remember when I was fixing IBM PC's back in the mists of time we opened up an old 5MB Seagate drive and managed to get it spinning - with our fingers! It continued working quite reliably thereafter for quite some time, IIRC. However, there was another drive we tried that one, but it turned out it had suffered the worst drive crash in history - the RW head was literally *buried* in the disk, as if someone had taken a hammer to it. But it was a completely sealed unit beforehand. If you're desperate, you may try prying it open and twigging the platters. But it may well be more than just the stickies - my experience of late has been that drives are much better protected from that occurrance. Best of luck with that! Dennis

Now a reseller >on the other hand... On the Lisa 1 topic... I just found out tonight that I in fact DID used to own a Lisa 1... I had always thought my only Lisa's were 2's and MacXL's (of which I have none any more). I was showing my brother my copy of Collectible Microcomputers, and he looked at the Lisa pictures. He said he always thought the double openings on the Twiggy disks were cool. I asked when he had seen one, and he said that the first Lisa we bought had those drives. I just about started crying. I could stomach the fact that all my Lisa 2's and MacXL's were either traded in or thrown out... but to now know that a Lisa 1 was also scrapped... it just kills me. -chris <http://www.mythtech.net>

Those drives were absolutely crap. -brian. --------------------------------------------- And then there was JTS... Other than Kalok and JTS, the only drives I consistently had problems with were the old ST-200 series Seagates. Mind you, they ran 24/7 for several years, but ultimately all (4 or 5) developed the stickies. Always embarrassing, because the systems were only shut down by me doing some kind of maintenance or mods, the old "but it worked fine until you touched it" syndrome. Fortunately, all they needed was a little prying & twisting with a small screwdriver on the spindle to free them up, and remarkably, they worked fine again with no problems or errors (to my great relief, and until the next time I shut them down). No problems with the old miniscribes though, still have a box full, all working, and no unusual failure rates with Micropolis either; it really is a matter of personal experience, not very meaningful statistically. And Philip, I'm going to write you directly about that paper tape stuff as soon as I sort it out; promise! mike
