Hi I've been searching on the web for a power cord for my ATC-510. I ran
across something saying you found one or found a place where you could find one.
I know it was a couple of years ago that you posted the message. Any help I
could get would be appreciated.
Thanks,
Jeff

Yes, you can, except that for UNIX systems like 4.3BSD-Quasijarus it's magtape
rather than perfotape.

With the initial FPGA implementation this will be problematic since all FPGAs
that I know of (sufficiently large ones anyway) come only in those damn BGA
packages. But if/when we can fab a real chip, I would definitely use a more
hacker-friendly package if the package choice were up to me.

That's a tough one too, though I have heard that making the required Class 100
clean room is not that hard.

Well, as Ethan pointed out, the 730 used an 8085, so I don't really see a
problem with using a Z80 or even an 8086 (hey, before everyone attacks me, it
ain't a Pentium, and it *is* of the right age).

Look, that was meant to be tongue in cheek! I can't imagine how could someone
take it seriously...

I'm located out in the country with only dial-up access, and the Franklin "package"
is over 100 megs - I'll try to arrange to have it placed somewhere where you can
grab it, otherwise, I can just send you a CD. I could trim the package a fair bit
if necessary - I've got a fair number of reference books and other material scanned
that you couldn't legitimately post on a web site anyway.

Sure, I can include some - I have them on file already.
I'll contact you via email when I have something in place that you can
access.

Hi Dwight,
I'll keep you and everyone else who has responded informed on whatever
material I am able to collect.
Btw, I've got scads of 8080 software that I wrote for my Altair which
could be easily ported to the H8 if anyone is interested - Including my
own disk operating system, BASIC interpreter and even a C compiler -
The OS was originally run on a NorthStar 10 sector hard sectored disk
system which is probably not that different from the Heathkit one.
I don't have a disk system for my H8 :-( .. if anyone knows of one or
comes across one, I'd like to hear about it.
Regards,

Someone who is truly dedicated to the cause of computing, who understands that
computing technology took the wrong turn about 20 years ago, and who is
dedicated to fixing it and setting it back on track.
That's why I'm building a new VAX, a real bona fide VAX product just like DEC,
NOT an emulator.
When the Republic of Mars declares independence and holds its first presidential
election, I'll definitely run with a platform of immigration and customs laws
that would require migrants from Earth to leave their pee seas behind and allow
only Classic Computers to be used in the Republic of Mars. Supplying the entire
Republic of Mars with enough VAX processors will be no small task, and the
limited stockpiled of old DEC gear will certainly be insufficient. We need new
production.
We need new real Classic Computers in full production. Emulators are not the
answer: what are you going to run your emulator on if non-Classic computers are
banned?

By development software I assume you mean the tools for working with Verilog
(simulation and synthesis), right? I'm using the open source Icarus Verilog and
it can run on anything, though since it's written in Anshit C I'm forced to use
gcc rather than native cc. I guess if necessary it can be run through
unprotoize and thus made truly portable.
Not sure what you mean by bootstrap software, if you mean things like VMB,
that's written in VAX macrocode and runs on the VAX, so I don't see where the
problem is.
I'll also have a real console FEP to implement the functions of Chapter 10 of
the VAX spec (lacking the real STD 032 I use the chapter and section numbering
>from VARM 2nd ed.), for which I will use some 8 or 16-bit microprocessor of the
appropriate time period. Fortunately there are 8/16-bit microprocessors that
existed at the time of VAX-11/7xx and are still made (Z80 and 8086 come to
mind).

The biggest problem you'll have is that hard disks will
fail on Mars. The atmosphere is not thick enough to float
the heads. You'll have to go back to paper tape and punch
cards.

Hi
Actually the worst I've seen is painters. They remove covers

that I've seen, they shorted a hot wire to ground so their fix
was to go to the circuit box and swap neutral and ground.
Nice surprise when I had to fix the water heater.
I don't think UL has anything to say about both lines being
switched by a common switch. I think they only talk about
an independent switch on neutral as being a problem.
UL is only interested in safety of the operator and not
the repairman. As long as it doesn't make the chassis hot
or start a fire, you can get UL on something that blows
up the electronics of a unit every time you turn it on.
