Can anyone identify this S100 serial board?

by ethan＠757.org

Trying to identify the S100 serial board in my Imsai 8080. https://imgur.com/eZyOVT5 I assume it was a kit. There are wires from behind one of the ICs that go to DB25 on the rear, along with other DB25s with a few pins (maybe cassette input.) Any help appreciated. -- : Ethan O'Toole

Another DCJ11 oddity

by jnc＠mercury.lcs.mit.edu

So, if one looks up the Cache Control Register in, say, the KDJ11-A (EK-KDJ1A-UG-002), one sees (in section 1.6.2.1) that there are _three_ ways to disable the cache: bits 2, 3 ('force miss'), and 9 ('bypass cache'). Looking at the DCJ11 manual (EK-DCJ11-UG-PRE) doesn't provide any additional insight. (The 9 bit one is slightly different than the other two, because it causes cache contents to be invalidated as the code runs, whereas the other two don't.) What is going on here, does anyone know? I'm _guessing_ that this is for compatability with the -11/70, where the cache is divided in two ('two-way set associative'), and either half can be disabled separately (using the 2 and 3 bits in its CCR). I suppose only someone who worked on the DCJ11 would know; but I have no idea how to track down such a person. Noel

SGI IRIX gcc 4.7

hi I am trying to build gcc v4.7 on a remote IRIX machine (not my property, thus I can't access it 24h/7) with these (1) gnu-files, patch, and scrips (you can see how things are configured for compilation) I am stopped at the ppl v0.11 stage with the following error that I am not able to understand neither to solve any hint? thanks /usr/nekoware/gcc-4.7/lib/gcc/mips-sgi-irix6.5/4.7.1/../../../../include/c++/4.7.1/cmath: In function 'typename __gnu_cxx::__enable_if<std::__is_arithmetic<_Tp>::__value, int>::__type std::fpclassify(_Tp)': /usr/nekoware/gcc-4.7/lib/gcc/mips-sgi-irix6.5/4.7.1/../../../../include/c++/4.7.1/cmath:814:35: error: 'FP_NAN' was not declared in this scope /usr/nekoware/gcc-4.7/lib/gcc/mips-sgi-irix6.5/4.7.1/../../../../include/c++/4.7.1/cmath:814:43: error: 'FP_INFINITE' was not declared in this scope /usr/nekoware/gcc-4.7/lib/gcc/mips-sgi-irix6.5/4.7.1/../../../../include/c++/4.7.1/cmath:814:56: error: 'FP_NORMAL' was not declared in this scope /usr/nekoware/gcc-4.7/lib/gcc/mips-sgi-irix6.5/4.7.1/../../../../include/c++/4.7.1/cmath:815:7: error: 'FP_SUBNORMAL' was not declared in this scope /usr/nekoware/gcc-4.7/lib/gcc/mips-sgi-irix6.5/4.7.1/../../../../include/c++/4.7.1/cmath:815:21: error: 'FP_ZERO' was not declared in this scope gmake[3]: *** [Box.lo] Error 1 gmake[3]: Leaving directory `/root/ghdl-for-irix/prereq/new-gcc-v4.7/ppl-0.11-build/src' gmake[2]: *** [all] Error 2 gmake[2]: Leaving directory `/root/ghdl-for-irix/prereq/new-gcc-v4.7/ppl-0.11-build/src' gmake[1]: *** [all-recursive] Error 1 gmake[1]: Leaving directory `/root/ghdl-for-irix/prereq/new-gcc-v4.7/ppl-0.11-build' gmake: *** [all] Error 2 (1) http://www.downthebunker.xyz/wonderland/chunk_of/stuff/public/retrocomputin…

HP 5061-6565 scsi loopback plug

by aek＠bitsavers.org

Someone working on simulating the scsi DIO board in MAME asked me about the scsi loopback test plug. Anyone ever seen one? Is it just wires or are there active parts doing the loopback?

KDJ11 misfeature

by jnc＠mercury.lcs.mit.edu

So, it appears that the KDJ11 (definitely the -A, and probably all of them) cannot execute code from the PARs - one gets a NXM trap. (Definitely the kernel I PARs, I haven't checked all 6 sets, but I can't see why they others would be any different.) Has anyone else run into this, so I can be sure I'm not confused? This is a mild pain, because it's nice to be able to put short 'scope loops in them, either to debug a memory card when you don't have any working memory plugged in, or when you don't want the bus 'contaminated' with instruction fetch cycles, etc. Noel

Making a bootable LIF CD for the 9000/382

by aek＠bitsavers.org

brain fade, I know I've made a HPUX 9 install CD before but I've forgotten how you make one that can be booted by the LIF boot rom in the machine.
