Tektronix 1240/41 diagnostic lead sets - resend

by jnc＠mercury.lcs.mit.edu

For the benefit of those (like me) who read CCTalk via the Web archive, and thus missed this as it came in during the period when the server thought it was 1970 (and it thus went into the March 1970 archive... :-), a re-send: -------- Hello all, I'm setting up to make one of these (part # 012-0556-00) for my own use, and can easily make more if anyone needs any (although I will need to order some of the parts needed, if so). So if anyone needs one, and would like me to produce one for them, please let me know (ASAP, so I can order the parts). I imagine the cost will be on the order of $10-$15. Note that i) you have to have a P6460 probe/pod to use them (the TTL P6462 probe/pod will _not_ work), and ii) full automatic testing on a 1240D2 18 channel Data Aquisition Card requires a pair of diagnostic leads (which is why I'm making one - I found one on eBay, but only one).

Looking for manuals for a Gridpad 1910

by bob099＠centurytel.net

I have a working 1910, everything seems to be working. Except the memory cards, not sure if they are bad or I don't know how to check them. On screen keyboard is working as good or bad as expected, battery is dead but looks easily rebuildable. Most of DOS seems to be missing, can it be replaced with Free Dos or another version? -- But if any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel I Timothy 5:8

Anyone have a M8340 (EAE) schematic rev.D? Or M8341 rev.D sch?

by steve＠tronola.com

Hi Folks, We're trying to get an EAE (extended arithmetic element) board set working in a PDP-8/e. It turns out that DEC made changes which render M8340 rev.D incompatible with M8341 rev.D. (Both of the boards we have are rev.D, sigh.) M8340 rev.D requires at least an M8341 rev.E. We would like to modify the boards to be compatible but the only schematic of M8340 that we've been able to find is rev.F. So it's difficult to figure out what changes are needed. If anyone has an M8340 schematic earlier than rev.F or an M8341 rev.D sch, that would be a huge help. The goal is to get Spacewar! working on the PDP-8/e for the upcoming VCFSE show. This version of Spacewar! requires the EAE. We GOTTA get Spacewar! working for the PDP-8's 50th! :) Please help. Thanks, Steve PS: The revision letter can be found in the lower right-hand corner of the DEC schematics that I have.

I did see that after I read the comments. Very cool. Clear and Black are definitely two good choices. -ethan

Nicolet stuff

by dkelvey＠hotmail.com

Hi Bob I'd gotten the hard drive for the Nicolet but not had time to fiddle with it. I'm currently redoing my code for the floppy drive on my Nicolet. I have a couple disk platters that should be able to be used for the hard drive ( and one that had a head crash ). I'd cleaned up the heads on the drive and with the new disk, seems OK. I've not fiddle with it since though. I was wondering if you'd like to fiddle with it on your Nicolet. You could barrow it for some time and install the demon code on it. On a separate issue, when I'd gotten my Nicolet, I had 2 failed ICs. One was a 7474 and the other was a DTL with expanded input ( I swapped a location that didn't need the expander input and use a TTL there for that part ). I just got started again and found the address wouldn't increment. After some frantic trouble shooting ( knowing it was Saturday and most places would be closed tomorrow for parts ), I finally traced it to a bad 7404. It is not easy without an extender card. I'd attach a couple wires to locations I wanted to see and stick the card back in. I must have pulled an inserted two of the cards 30 times. I hope is wiped the connector pins good and clean. If you should decide to make an extender, I'd split the cost of the boards with you. I think it would be easy to make three separate extenders and put a rail across them to hold them together. It wouldn't be too bad to just have the three separate ones and be careful connecting things. I believe they are just three 100 pin connectors, like S100 boards use. Dwight
