NVRAM battery replacement (was Re: Thick Net Cable Terminator in Sydney Australia)

Are there any components other than >the battery in the potted lid? i.e., can I just remove it entirely or >do I have to perform delicate surgery to seperate the front leads and solder >wires onto the front of the I.C. where the lid used to connect? Yes there are but finding the battery is easy with a small magnet as it's steel cased. then grind off the plastic in that area till you hit it. pry it out and add wires to another and your all set. I can do them in my sleep. Allison

Lats time I bounced my speedo off the 150 peg in my 70 Certain thinly-patrolled stretches of Route 95 between DC and Georgia. However I'll be the first to admit that I don't do that very often...this country is full of egomaniacal cops who are too lazy, scared, or inexperienced to actually [gasp] CATCH CRIMINALS...so they bitch about how people drive instead. > Roadrunner GTX in the way-out secluded desert (about 1978) I got nailed by a > state trooper and the fine kept me from buying gas for a few weeks.

My grandmother (who was a VERY wise woman) taught me that the only NEEDS in life are to paying taxes and dying. Everything else is optional. -Dave -- Dave McGuire Laurel, MD

Speech chips again

by pete＠dunnington.u-net.com

A few days ago there was some discussion of speech and sound chips, which prompted me to dig in the spares box and extract a TMS5220 speech processor and the ROM that goes with it, made by Texas Instruments. For those who don't know, this was a rather interesting speech processor: it worked by setting up digital filters to model certain characteristics of the human vocal tract, and then used those filters (dynamically adjusted) to turn white noise (simulating moving air) or other sounds into speech. The ROM didn't store digitised sound at all, instead it stored the information about what type of source to use and what filter parameters to set up. Hence it was not much use for anything except speech, but it did a pretty good job of that and used less memory than, say, a Digitalker did (I have a Digitalker chip set as well). The TMS5220 was most often used with special serial ROMs, and was used as the (optional) speech processor in the BBC Microcomputer -- that's why I have a couple of sets. It was also used in some arcade machines, in one if the Texas home micros (TI99/8?), one of the Coleco machines (I think), and an obscure British 68000-based machine called a uMicro 2000. Texas made a couple of standard vocabulary Phrase ROMs, and custom ones for particular pusposes. The arcade machines and BBC Micro used custom PHROMs, -- TMS6100NLL in the Beeb -- but one I have out of a uMicro 2000 has a generic part number: VM61002NL. I know that the first standard vocabulary ROM was type VM61001NL so I imagine what I have is another standard part. Alas, I can no longer find the data sheets for either the TMS5220 or the PHROMs, and a web search hasn't turned up anything useful. Texas' website no longer has any info on those devices, neither does the company who deal with their obsolete products. Does anyone have any information about these things? I'd like to see (or hear!) what's in the PHROM I've found. -- Pete Peter Turnbull Network Manager University of York

US Tour

by Hans.Franke＠mch20.sbs.de

Since I will spend the next 7 weeks in the US, on a cross coutry tour, starting in Baltimore in about a week (sorry, due circumstances I will miss VCF East by 5 days :(), I'd love to hear some hints about places to visit. The rough schedule will touch MD, NY, CT, RI, PA, OH, IN, IL, KA, CO, WY, MT, ID, WA, OR, CA - or so. Any Ham fests, swap meets, etc ? Gruss H. -- VCF Europa 3.0 am 27./28.

Of course my Ranger is > basically a Mazda with a different trim and other parts. Actually it's a 3.6L with a LOT of torque. Though I'm no motorhead, I udnerstand that two spark plugs and two ignition coils per cylinder helps quite a bit, as does the very weird tuned-induction system in the intake manifold. I drove a 6.6L FireChicken for several years...this [stock] 911 will blow its doors clean off, above OR below 100MPH. -Dave -- Dave McGuire Laurel, MD

VMS setup

I'm going to have to disagree with Allison on this one. I strongly believe that a VAXstation/MicroVAX 2000 is not a good system in this case. There are two major problems that I see, both related to the disk interface. You're stuck with a MFM disk, all of which are getting very old, and you can't connect a CD-ROM. If you're only going to have one OpenVMS system, do yourself a favor and get one with real SCSI! Also, why V5.4? The preferred landing zone for V5.x is V5.5-2. Zane

I'm pretty sure the Cosworth's used the older iron 4cyl block, not the first-stab-at-the-Alcoa process, which Porsche used quite successfully in the 928... -dq

Intersil PDP-8 prototyping kit

The intercept was not the only one offered by intersil. The intercept was an expandable system where the supersampler was a single board thing to play with.
