What page are you looking at on Manx which has the broken link? Do you have the part number for the manual? That title is a rather generic one to use for searching.

KY11-LB drawing error

by jnc＠mercury.lcs.mit.edu

So, now that I have the 85S68 datasheet in hand, it turns out there's an error in the KY11-LB drawings. (I just couldn't understand how the circuit could possibly work, until I discovered that!) On the two RAM chips (E11 and E27, used to hold the bus address, keypad data, etc) the "Output Store" and "Output Disable" labels are reversed. (Not the pin numbers, etc - just the labels.) I.e. 'Output Store' is actually pin 13; it is tied high (as shown on the drawings for that pin). I have 'fixed' a copy of that page from the print set, and will (soon) issue an updated PDF. Noel

Servicing DEC-T11 based products with a Fluke pod?

by johnwallace4＠yahoo.co.uk

Hi John, In the apparent absence of other T11-related suggestions, are you aware that there are a couple of T11-related manuals on Bitsavers, at least one of which has schematics? There's the T11 Users Manual, and the T11 Evaluation Module Users Guide: www.bitsavers.org/pdf/dec/pdp11/t11/ Nothing about Fluke pods, but maybe something more than you have at the moment? Best of luck John Wallace

Does anyone have an 85S68 (16x4 SRAM) datasheet? I've looked online, can't find one. Thanks in advance! Noel

Recomended: IBM 100 aniversary video

by rdawson16＠hotmail.com

Some great stuff here, and yes it a promotional film but note: Patty McHugh, the Mother, of the motherboard, and the PC segment. Brooks, and the 360 project (I recommend his Mystical Man Month for any project manager) What was missing, how about FORTRAN, and Jim Backus?

Most of them were on the an HP site for awhile. I don't know what survived the corporate split. Thanks Dave. The parts I studied seem quite clear (as expected). I was thinking I might add IVprime support to DECnet/Python. Maybe that's a bit silly, maybe not. It clearly is valid to do so even if your interface isn't Token Ring, though I suspect it hasn't been done before. paul
