Dear friends
I have a blog in portuguese where I write my adventures in repairing and
maintaining old computers. Today's post is:
http://tabajara-labs.blogspot.com/2018/04/msx-yamaha-yis303yis503-e-seus-ir…
Should I post updates to my blog here? Are these wanted/allowed? I believe
yes to both
Thanks

I'm trying to understand various hex formats so I can add them as output
options to minipro[1]. I went looking for existing code to convert binary
to Intel hex and found repeated copies and references to "format83.c" by
Erik Lindberg. It seems to do what I want, but I'm unclear what "Intel
HEX 83 format" is supposed to mean. Based on what I see at
http://www.math.purdue.edu/~wilker/misc/DEVEL/0036/A-6804/BIN2INT.C, this
program only creates hex files in the I8HEX format, as described in
https://en.wikipedia.org/wiki/Intel_HEX.
Of course, I'm going to have to support the I16HEX and I32HEX formats too.
Based on what I find in format83.c, this shouldn't be too much trouble,
but I really want to know what "Intel HEX 83" is supposed to mean.

A: Because it fouls the order in which people normally read text.
Q: Why is top-posting such a bad thing?
A: Top-posting.

i know of pdp 11 thats going to get lost to a building demolition in
winnipeg if i was in the city i would jump up and down to grab it it my
self ive got most of the paper tapes for it and the drawings i managed to
rescue a while back.. theres a office on the otherside of the floor just
about other side of the wall from the 11 that has more manuals and
documents possibly 8" floppy disk software in said room (more like a closet
8x8 room
there some vandle damage to the front of the 11 was painted with some spray
paint
and the spectrimanalizer its atached to was smashed
also theres also a room with the big built in desk for a control room
dating back to the 60's 70's been striped of some stuff if anyonres looking
for that sorta stuff
For those follow the rescue of equipment from Pete Lancashire's place
outside of Portland ...
I went out there last Friday. Pete was unavailable, so a friend of his
let me and showed me where to avoid stepping.
The amount of stuff there was impressive/amazing/overwhelming. Aside
>from the test equipment and old telecom equipment that was pointed out
when I was shown around, it was hard to focus on one thing because I
would immediately see something else interesting that grabbed my attention.
I picked up seven Sun SPARC systems and three Compaq-branded Alpha systems.
The Alpha systems all went to a local (Seattle) person who is talking to
Bill Gunshannon about possibly getting one out to him. One of the Alphas
was a DS20 deskside and I never figured out what the other two were.
They were narrower and longer than the DS20. There were also some loose
72G Ultra3 SCSI HDDs.
The Suns were a SS1, SS2, two SS5s (one with a Netra top cover), two
SS20s (one with its cover removed and MBus card and memory lying near
it) and a SS1+ "prototype". I am keeping the SS1+ and a SS5. I have
found a home for a couple more of them and will be looking for a home
for the rest.
The SS20s are the most problematic. As you would expect from a system
with its top cover missing, one of the SS20s does not display any
diagnostic output or get to the OBP prompt after being powered on. The
"good" one displays a "replace motherboard" message while going through
its diagnostics.
Also, as you might expect, the one called a prototype was the most
interesting to me. I am a long-time Sun employee and, while I wasn't
around when the SS1+ was developed, I know people who were. It isn't
like any prototype that they knew of. Still trying to figure out exactly
what it is. The top cover is metal and slides over the chassis (not
plastic and pivots into place like a SS1+. There are no external
markings on it. It has a Sun SS1+ motherboard, Sun0424 HDDs, and uses
SS1/SS1+/SS2 HDD carriers, but has a Sony (not Sun) labeled power supply.
As far as the 029 keypunch, it is still there. There was some confusion
and the people who were supposed to come get it didn't. I have described
to them where it is and how I would go about removing it.

Has anyone made a GDB front-end for SimH? Just curious. Seems like it could
be an interesting way to tie an IDE to SimH, if one were inclined.
Thanks,

Hello,
People have been earching for PDP-10 MDL for a long time. Finally, we
found source code for TOPS-20 including slightly bit-rotted ITS support.
It has now been fixed and is up and running in ITS. Twenex people are
welcome to give it a go too. This is published with permission from
Chris Reeve and Tim Anderson:
http://github.com/PDP-10/muddle
Next is, of course, trying to run Zork. How to do that is an entire
research project of its own.
Best regards,
Lars Brinkhoff
Well, the ones listed now have been re-listed at least once. :-(
I was just contacted by the Living Computers Museum. They emphasized they are a 501(c)(3) org. :-)
I donate to the CHM. I will probably give them first shot.
Does anyone in the group have access to documentation for the Cybernex APL-100 video terminal?
All that I've been able to locate is a 4 page brochure for it; they were originally made in Ottawa, Ontario, Canada.
Any help would be greatly appreciated.
