Graphis, 1997.
Mini-review: |<00|_ pictures of computers and concept models and other
things. Emphasis is on industrial design, not technology. The text
is marred by typos and an overall feeling that the author thinks Apple
and those responsible are just too cool for words.
Maybe they are. Or maybe it's just that I've had enough of dealing

I would also recommend that if you come across a company that helps with old
systems like the story about the tape drive, be sure to let the company know
their help is appreciated. hopefully that will still give them an incentive to
continue to offer help.

Ah, but you are (especially for mainstream stuff) reasonably rare. The
average I-bought-my-computer-at-circuit-city-and-got-a-free-hair-dryer

Dunno if there's a solution. I try to find a knowledgeable support person

I disagree. Apple, at least to me, represents that innovation can live in
today's computer industry, and that being different makes you ahead, not
behind of the crowd. (And yes, I thought that BEFORE Apple's current
marketing campaign.) Looks cool, but I want more information, and, as most
people go, they'll need reasons to want a $1.3K over a $600-$800 PC.

It's a QBus controller for SMD drives. It will support two physical

We need to know the suffix (SC03/A, SC03/B, SC03/C) as there are at least
three versions, emulating different drives. I have an SC03 which emulates
RM03s, but there's an MSCP version as well. I've got the manual for this

Exactly. I also expect if the technical support is not via phone (IE from
e-mail, web based, etc.) to get a timely answer. With my old soundcard, it
was 3 months, by which time I'd gotten so fed up I'd figured it out anyway.
Now I use a real Sound Blaster AWE 64. I like the cool sound.

I was at the scrap yard yesterday, picking up some aluminum blocks to
play with on my new CNC milling machine, and decided to take a stroll
out where they occasionally dump old mainframe parts. It's just this
huge mud lot about 2 blocks square, with big mounds of twisted metal,
wire, cable, crushed cars, and all kinds of other junk, with a bunch
of bits of electronics thrown in more or less at random. I wasn't in
the mood for a lot of climbing, so I just poked around the edges. I
found a board about 18" square sitting on top of a barrel. When I
picked it up, it was *way* too heavy for the size. Flipped it over
and saw another, smaller board screwed to the bottom. It was marked
"DataRAM". I thought "Oh no - surely not. It can't be core memory!
But it's so *heavy*! What is it?" I took it along. I also found an
old controller module of some kind with an RCA 1802 and support chips
on it; now maybe I can finally build a real Elf. Anyway, they sell
everything by the pound, and the two pieces cost me about $2. Brought
it home, removed all the screws around the edge, pulled off the
smaller board, and guess what? Acres of core! Tiny little ones, too
- I haven't seen that much core, but the other small piece I have has
cores with a center hole about the size of a pencil lead. These were
so small they looked like grains of sand, or salt. Had to use a 12x
magnifier to see them clearly. By my count, there are about 100 per
inch in both directions, and it's about 8"x10", with a few gaps here
and there, so this gives... ummm... (square root of 7, carry the 9...)
uh... something under 800k-bits or so? Does this sound right?
Anyway, I was pretty pumped. I may go back and do some serious
climbing and burrowing this weekend...

<be interested. Will they be SYSGEN-able? That's one thing I miss in
<the RT-11 image that came with the emulator. But I'm not going to look
<a gift horse in the mouth.
Rt-11 does not require sysgening like RSX or RSTS So just the binaries of
the standard monitors (SJ, FB, XM and BJ) and the standard drivers
is all that's needed to use it effectively. RT-11 really only requires
the disk used to boot to have the boot blocks installed (copy/boot)
and it will run on all PDP11s and most all disks. Known disks supported
in v5 were the all the RXnn drives regardless of controller
(rx01/2/3/50/33) all the RD drives, RK drives, pro350(DW/DZ), TU58
tape(bootable and useable as system device) and most of the mag tapes.
V5 includes a ramdisk called VM that can even be booted assuming you have
plenty of ram. An 11/23 with 1meg ram running RT11FB will have plenty of
space in VM (about 1900 blocks) for a useful system. I know as I run it
on 11/03, 11/23, 11/73 using RL02, RD5x, RX50, RX33, rx02, TU58 and VM:.
A useable system fits on any 256k(497 blocks) dual device (tu58 or RX01).
A rx50(800blocks) system is fairly roomy. Any hard disk is fast and
plenty of room even small 5meg(10,000 blocks) RD50s. The full V5 kit
minus .mac files fits in about 4-5000 blocks. Removing the unused drivers
and other misc files really cuts this down. A block is 512bytes.
I didn't mention but RT-11 is NOT a memory hog and even a PDP-11 with
16kw can run a useful system. Being a low fat OS it is also very fast
permitting even slow PDP-11 processors a chance to look good. It's
basic commands look just like PC dos.
An emulated V4 system should be useable to do PDP-11 program development
and run standard monitors. the minimum hardware needed is any PDP11
(even the falcon card!) 16kw ram, mass storage (floppy or hard disk)
and at least one DL serial line (console). The boot an even be toggled
by hand.

I think you may be confusing my remark with Tony's. I remarked that
"all circuits are amplifiers" meaning that the general circuit can be
modelled as taking an input, applying some sort of gain, and producing
an output. A gross oversimplification, but I wasn't talking about the
active/passive issue (gain>1 => active, etc.) Tony made a slightly
different remark, "Digital circuits are built with analogue parts".
Unlike mine, this is not an oversimplification, it is absolutely true.
And has nothing to do with amplifiers. You can build a digital circuit
element with diodes; they are analogue parts, and they don't amplify.
Clear now?

I couldn't quite read your diagram, I'm afraid. Was it series capacitor
followed by shunt diode? Looks like it refers the input to the lowest
value it (the input) ever takes, rather than to ground or a fixed
reference.

Roughly what I thought. I wasn't sure whether people would class it as
a computer, but I think it is no less of one than a 4-function pocket

Is there a limit to how big a RSTS filesystem can be?
I'm told 8.0-07 doesn't support RA92s. But the fact that INIT knows what
it is tells me otherwise. All I have to do is find the CMP instruction
stopping me from formatting this disk and off we go. The question is,
is the RSTS filesystem used in 8.0-07 able to handle a drive this size?
Is there some filesystem-induced wall I'm about to walk into?
-------
Of course everything I've dragged home in the last few months simply pales
in comparison to the prototype Apple //c I brought home today.
I was on my way back to work in the early afternoon and was trying to
decide if I should stop at my favorite thrift store on the way which would
put me in traffic, or if I should cut across the hills to get back
quicker. I thought to myself that there may just be something at the
thrift store that would make the trip worth it, so the thoughts of finding
something cool won over my need to get back to the office. This is one
case where I'm glad I let my irrational urges get the best of me.
The first thing I saw when I got to the electronics section was an Apple
//c, and I thought to myself, "Hmmm...do I want another //c?" (since I
have like 3 already). But when I picked it up I noticed something strange
about it. The case was smooth instead of having the normal texture. I
flipped it over and noticed there was a small green sticker on the bottom
instead of the normal grey one with the Apple //c wording and part
numbers, etc. The sticker read "Apple Computer Inc., PCSD MFG, 3087 North
First Street, San Jose, CA 95134" then the words "Prototype" and "Test
Equipment" with check boxes next to each. "Prototype" was checked off.
Of course phrases like "holy shit" went through my head. The label also
had a serial number of "P1160" and at the bottom was "WARNING: PROPRIETARY
PRODUCT". Now this was too cool for words to describe (<--- isn't that
deliciously nerdy?)
When I got home I opened it up along with a regular production //c and
started comparing the motherboards of the two. There were several minor
differences. Some silkscreen lettering was different and there were a
couple minor component changes, but nothing significant and for the most
part the board layout was identical.
I pulled out the power supply on the prototype and the production model
which unveiled the following:
Prototype Production
--------- ----------
TERI MAIN LOGIC MAIN LOGIC
820-0115-0 820-0115-C
(c) 1983 APPLE COMPUTER
APPLE COMPUTER (c) 1983
Was "TERI" the codename for the Apple //c?
A couple other interesting differences: on the prototype, there was a
small board with the labeling "Apple Computer Network SKA156-00" in the
place near the serial port where on the production model is a simple
transistor pack. The "network" board simply has transistors on it. Also,
at location C19 on the proto is a 74LS161 whereas on the production there
is a 1.8432 Mhz crystal. On the proto, the CHAR GEN EPROM is socketed and
the system ROM is an EPROM with a sticker which has "v1.0 5/19 5F85"
written on it. Lastly, for the motherboard product number (all Apple
components have a product number in the form of xxx-xxxx-x) the proto had
6xx-xxxx-whereas the production has 612-0128-E.
Oh yeah, the proto had a spider living in the connector of the power
supply. Spiders find the stupidest places to spin their web. What the
hell did he expect to come crawling through there!? I was just going to
flick him off into the room but if my wife found him a couple days from
now she would've fainted, so I did away with the poor little sucker.
R.I.P.
Here's where you envious types shoot yourself: I paid $2.98 for it.
:)
I've found some of the best stuff in thrift stores, but this beats all.
It will be proudly displayed right next to my prototype Apple //gs at the
next Vintage Computer Festival.
