Hi Guys The combination of shipments going out and resposes to the survay (thanks everybody) have shown up some diffences between 8/e's. The first and most important one is the change of markings for the selector switch where they must have changed switch type at some point. Its the case that you will have one or the other. I can get another screen made up with the angled markings at switch positions 1 and 6. When you order you can then specify which one you require. The other two are cosmetic and have no impact on operation. Firstly there is sometimes a line around the area where the selector switch is located. Secondly vertical lines dividing up the lamps into groups of three are sometimes present. I can't yet work out if there's any pattern to where they do and dont appear. (not enough data) The easiest way to fix this is to either add the markings to all the panels or none of them. Comments please.... Rod

HP 2113e Battery resistor

by marc.verdiell＠gmail.com

Ah thanks, this is what these are for, thermistors. They are supposed to monitor the temperature somewhere I suppose? Attached to the batteries? The power supplies? The computer won't start without these I understand? Sorry I am a bit of a newbee with HP 1000's. Have not tried to power mine quite yet.

Need DZQ11 (M3106) Print Set

by jnc＠mercury.lcs.mit.edu

{Re-send, since apparently a lot of mail to CCTalk yesterday went into the bit bucket...} I guess I've struck out here? That's such bad luck; other things, there are multiple copies out there, but apparently none at all of this one... Oh well, I guess I'll start with the DZQ11 TM, and with an ohm-meter try and trace out the initialization circuitry (which is clearly broken) at least. Noel

Wright Line punch manual

by COURYHOUSE＠aol.com

Yes, that is the one we have here at the museum! yea pretty easy ( compared to a teletype) but we just like to have manuals or copies of them for everything we have here in the various collection areas.

I suspect that boards like the Raspberry Pi, Arduino, etc. might get a lot more interesting if they can affect the real world. See if a servo motor adds some appeal. -- Mark J.

> Is there a reason to prefer 7400 series over CD4000 series logic? If you can find real TTL, yes, I would say so. It's less static-sensitive and it's more tolerant to things like hooking two outputs together by mistake. But note that there are many chips that have more or less TTL interfaces (TTL voltages, TTLish numbers, and in some cases switching thresholds) but are actually CMOS - the 74ALS series comes to mind. Of course, if someone somehow builds CMOS chips with TTL's ESD tolerance, short-circuit tolerance, etc, then great. But that's not what I've seen. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B

Intel ipsc/860 [QIC tapes recover]

by plamenspam＠afterpeople.com

I managed to rescue few tapes containg installation sw+c compilers, fortran and forge. While I was trying to make a backup all cartriges broke st some stage due to too old belts. The magnetic tape of 2 of 4 cartriges seems ok. So I'm looking for somone within EU who has experience in this to try to save whatever is possible. Regards, Plamen

When I visited ALR, a company in Irvine that evolved into making PC type servers and were absorbed into Gateway (name still is used) had a lab with a lot of hardware stations, and for the time good networking. At about noon or so one one of my visits for Sun Microsystems, about a dozen of the engineers showed up and proceeded to pull out hardware and cables, and displays at various stations and hooked them all up pretty quickly. This was in about 92 or 93, I'd guess. They converted the lab into a big Doom game for about an hour. I also found out the best time to round up and have casual consultations with them about things I wondered about with some systems. Thanks jim
