info? Micro Instruments memory voltmeter

by rigdonj＠cfl.rr.com

I picked up an intersting gadget today. It's a model 5203C Memory Voltmeter made by Micro Instruments. It has a four digit Nixie tube display and appears capture and display + or - DC or AC peak voltages. Does anyone know anything about these? It has two zero adjustments, among other things I'm trying to figure out exactly what they do. Neither of them seems to "zero" the meter in the normal manner. Also what does "Narrow band" and "wide Band" mean? Changing the setting doesn't change the voltage range so has to be for something else. Joe

by jsickles＠comcast.net

Hi, I'm also looking for an HP Extended Mass Storage module (hp 00085-15013) for the HP 85 (A/B). I'm trying to get an old disk drive (hp 9133 D) to work with an HP 85 B. I could probably find some HP 85 stuff to trade for this. Thanks. Jim Jim Sickles jsickles(a)comcast.net

TRS-80 Model III

by doug_jackson＠citadel.com.au

I know that the TRS-80 Model 4P uses a PLL to do the high res video mode, and that a common cause of crappy quality display is the setting of the VCO cap. My 4P was unsable until I adjusted the cap, not it is beautiful. regards Doug Jackson MSS Operations Manager Citadel Securix (02) 6290 9011 (Ph) (02) 6262 6215 (Fax) (0414) 986 878 (mobile) > -----Original Message----- > From: Curt Vendel [mailto:curt@atarimuseum.com] > Sent: Wednesday, August 07, 2002 1:43 PM > To: cctalk(a)classiccmp.org > Subject: Re: TRS-80 Model III > > > Sellam, > > Are the boot straps on eproms on the motherboards???

OT: Digital Watch Recommendations?

by bill＠timeguy.com

This is entirely OT, but since we're probably all gadget freaks here, I thought it would be a good place to ask. My "OnHand" PC watch recently bit the dust, so I'm in the market for a cool new toy to wear on my wrist. I've had various "DataBank" watches, a Timex DataLink, and the OnHand in the past. Not long ago I got a Kyocera PDA/Phone that handles most of the functions the watch used to provide, so now I'm just looking for something fun. I like BIG, HEAVY, INDUSTRIAL watches, so none of those effeminate little dressy things! I'm currently thinking about either a Casio camera watch, or a Timex "Internet Messenger" watch. Samsung has released a cell-phone watch in Japan, but not available in the US yet, priced at $1,000, and duplicates the function of my existing phone. Any suggestions?
