So somewhat OT - I've setup an 8 year old w/ an IBM PC XT w/ CGA. To say he
is less than impressed is understating things :). However, I am determined
that he will learn basic computer terminology, architecture, history (i.e.
how we got here) and at least get his feet wet with programming by learning
BASIC this summer.
Apparently teaching is not my strong suite - while I can talk about a larger
number of the above topics, especially at his level, organizing them in a
way to make sense is the problem. I was wondering if anyone could recommend
a good book that gets the basic stuff out of the way (what is the CPU,
memory, storage, etc. what are different the parts called, etc.) and maybe
another one that teaches an intro to BASIC written for a very young reader?
It would be nice if the book is in the PD or at least available as a PDF
that way he can read it on his Kindle. However, I am not averse to buying a
physical new (or used book) either.
Thanks.

Once upon a time there was a band made up mostly of SCO employees called
"Deth Specula". Their heyday was in the early to mid 1990s. Does anyone
remember them?

Which is the correct model number for the I/O & memory accessory for the
Heath ET-3400(A) trainers?
I see ETA-3400 and ETW-3400 used interchangeably. For instance, the d/l
manuals refer to the unit as ETA-3400 but many (most?) units, mine
included, are screened ETW-3400 on the case.
Anyone know what gives with this? Are there actually two different models
or revisions, as with the ET-3400 and ET-3400A?
Also, is there a way to tell if a Heath piece is factory-built? My
recently-acquired ETW/A-3400 has a board which almost +must+ have been wave
soldered and washed. It has no traces of home-assembly. Likewise, the rest
of the build is top-notch and looks like factory work..
Thoughts?
PS Still need a 2x20 header (like 40pin IDE) to complete this project.
Anybody got a spare?
Sweet. No where can I order 10 or so at a reasonable price? There is a guy one ebay selling one with hood at $22 a piece....

Sent from my phone - please pardon brevity & typos.
We fixed the RK05 disk this week. We replaced E3 (LM301A) and E1 (SN7404)
on the G938 Servo Preamp module. The COUNT PULSE FWD H and the COUNT PULSE
REV H signals from the G938 module are both working now. The drive will now
seek correctly using the jumpers described in the Maintenance Manual or
using seek-only instructions from the RK8-F controller.
We tried the OS/8 and LAPS-DIAL bootstraps, but the processor just halted.
The first page of core that was read from the pack contained a repeating
sequence of 2525-5252. Either the pack was used as a data-only pack, or
diagnostics were run on the pack. During the week I will use SIMH to make a
PDP-12 bootable OS/8 RK05 image. Next week we will use dumprest to make an
image of the disk pack, and then write OS/8 to the pack.

my real IBM clicky keyboard does not have usb so I tried various usb
adapters and they could be flaky,...
you would have to start computer then have to unplug and reinsert
keyboard connection etc...
anyone have a solve for this? thanks Ed#

Chuck! That would be great! Perhaps yours had newer brains in it
than my couple as mine have some years on them. if you still have link to
vendor that would be good too. My clicky keyboard is off the tower so
it has a long cable on it!
I love this keyboard!

I use a no-name cheapie keyboar+mouse adapter that looks like a "y"
cable more than anything. Works fine on USB for both. I think I paid
about $2 shipped from China.
I can get the chip ID if you'd like, but that assumes that you can find
another like it.

So in short i have six identical drives. Same manufacture, model, and
firmware. Three of them work fine, the other three also work fine but
they always show up as the wrong target.
For example i have a Sun D1000 storage array with 12 slots (targets
0-11). It doesn't matter what slot you put them in, these three drives
always have the same target number. One is target 8, on target 4, one
target 2. I doesn't matter one of the drives is by itself or together
with other drives.
Take the disk that always shows up as target two for example. If you
place this drive in slot zero, then place a normal working drive in slot
2, and finally attempt to write data to target 2 both drives will get
the write. The same effect also applies to reads. If you boot an OS with
the drives in this configuration you will usually get a panic.
I can verify the same behavior on my Sum V210 and Dell PE 2850. This is
such a bizarre way for a disk to act / fail. Has anyone ever seen this
before?
