Owww.. Don't you get a face full of flumes from the solder?
And because of the small parallax (eyes to mouth), don't you
have a depth perception problem here? As well as a stiff neck?
(Not to mention sucking on that piece of lead in your mouth.)
Try this. Holding the iron in your right hand, take about
8" of solder and wrap it a couple of turns around the tip of
your little finger (right hand) with about 6" extending toward
the tip of iron. You can control the solder by moving your little
finger back and forth. Sure, you will wind up with a few short
pieces of solder, but you can use them on jobs that don't take so
much gymnastics.

<What are WP and PC w.r.t the 9995? I'm reading the memory map and I don't
<understand what those terms are. A related term seems to be BLWP, which I
<don't understand either. (I'm only a poor 6502 programmer. :-)
OK,
WP... workspace pointer. back when the 9900 was new registers (memory)
really ate up chip space and TI had an archetecture in the 990 minicomputer
where register were in memory instead of in the CPU. So the WP is a pointer
that points to a block of 16 locations in ram that are addressed in
instructions as R0 through R15.
PC is PC just like the 6502. It's the instruction counter.
BLWP is an instruction that does several things.
It branches to a specified address.
It saves the WP and PC in the R14 and R15 of the new
workspace.
It then resumes at the newly specified PC.
Obviously it nees two parameters a new WP and PC. They are specified by
varios means (addressing modes and registers). Think of it as something
like a 6502 call and Push combined though it's more powerful.

I recently picked up about 30 150meg Bernoulli cartridges that have never
been opened. According to the chart on the back they should work on the
90meg.

How much of the documentation / flowcharts / source code / etc. will be
open source / GPL / freeware?
I've always wanted to build a multi-processor CoCo (the 6809 was designed
with simple multiprocessing in mind) but never quite figured out where to
start. These documents might actually give me a clue.
Just wondering,

A man was to be married and his friends threw him a stag party.
As usual there was much drinking and merriment. As the evening
wore on, the man was dancing nude and and hit his erect penis on
the fireplace, knocking himself out.
Concerned, his friends took him to the hospital. Following an
examination, the emergency room physician told them that their
friend's condition was stable, that he was bruised and sore, that
the medical term for his injury was complicated but in layman
terms, "He had broken his prick". They shouldn't worry though,
because he had supported the injured part with 4 tongue
depressors neatly bound with tape.
The next day, the wedding was flawless and the bride was unaware
of any problems. In their honeymoon suite, the bride was
spread-eagled on the bed when her husband emerged from the
bathroom and she said, "Come and get it , Honey, it's all yours.
I'm untouched by any other, this is pure virgin wool".
The groom smiled as he dropped his pajamas as he said to her,
"Check this out, Babe, still in the crate".
______________________________________
A guy was at the supermarket and after buying a few things he
began to queue up in this really long line for the checkout.
After about 15 minutes in the line he reached the checkout girl
and just at that moment he remembered that he needed some
condoms.
Not wanting to line up again he said to the girl "Oh I meant to
buy some condoms but forgot"
"Do you know what size you are ?" she asked.
"No".
"OK drop your pants and I'll tell you what size you are".
The guy then, not being the shy type, drops his trousers and the
girl has a feel with her hand and then says in the microphone "1
packet of large condoms to aisle 3 please", he pulls up his
trousers, the condoms are brought to him and he pays his bill and
goes on his way.
Another male customer sees this and thinks he'd like to have this
nice girl fondling his prick and so says the same thing to the
girl. A similar course of events takes place, only this time
after having a feel she says "One packet of medium sized condoms
to aisle 3 please", the condoms are then brought to him and he
pays the bill and goes on his way.
Also watching this course of events was a rather excitable 15
year old boy who then decides to queue up and try the same
routine.
"I'd like to buy some condoms please, but I forgot" he says.
"Do you know what size you are?"
"No."
"OK, I'll check. Whoops, mop and bucket to aisle 3 please!"

A man was sitting at a bar enjoying an after-work drink when an
exceptionally gorgeous and sexy young woman entered. She was so
striking that the man could not take his eyes off her.
The young woman noticed his overly-attentive stare and walked
directly toward him. Before he could offer his apologies for
being so rude, the young woman said to him, "I'll do anything,
absolutely anything, that you want me to do, no matter how kinky,
for £100 on one condition."
Flabbergasted, the man asked what the condition was. The young
woman replied, "You have to tell me what you want me to do in
just three words."
He quickly pulled his wallet from his pocket and slowly counted
out five £20 notes, which he pressed into the young woman's hand.
He looked into her eyes and slowly, meaningfully said...
"Paint my house."
______________________________________
A man went into a chemists looking for condoms. Unfortunately he
didn't know what size to get. The pharmacist asks him, 'Would you
like to find what size you are, Sir?'
The guy agrees and the pharmacist leads him into a room with a
board. The board has many differently-sized holes in it. The
pharmacist leaves, allowing the guy some privacy to match up his
dick with the right hole.
Three hours have gone by and the pharmacist wonders what is
taking so long. So, he knocks on the door and sees if the guy is
alright. The guy says, "Forget the condoms, I think I'll take the
board."

The guy below seems to have a bunch of old PC parts he was
going to dump. They're not "classic" in mine or the list's terms but
I know some of you here might be able to use them and he was
just going to throw them away. Told him I'd pass his email along.
You can get in touch with him at the address in the email below.

I didn't read your web page very carefully....so I'm not sure if you
purchase computer parts. I have many motherboards, I/O cards,
video
cards, memory, etc that I am looking to get rid of.
Let me know if you are interested.

I just got my hands on my first Kaypro - a Kaypro 4. Everything seems to work,
but it never boots from the only boot floppy I have. I tried reversing the
two drives and booting from the other drive and got the same results, so I'm
convinced it's the floppy itself.
Can anyone point me to a site where I can get the software to create a new
one from my win95 machine (if possible).
I have some questions. First, I tried connecting a 360k 5.25 inch floppy from
a PC to the kaypro. At first nothing happened, then when I changed the device
select to 0, it hung the machine every time it tried to boot. Should I
interpret this to mean you can't connect PC drives to Kaypros? If you CAN,
can you connect 3.5 inch drives to it? It would be far more convenient...
Also, on www.psyber.com/~tjc/ it says there's a western digital hard disk
controller. WD-1002-05 HDO. Is it possible to connect this to a K4? If so,
how? I don't see any open connectors on the motherboard offhand.
Anyway, the guy I got my K4 from has a K2 and a K2x - the latter of which
appears to be unable to boot, although I suspect reseating the chips would
solve it, and the former of which has a soda-contaminated keyboard with
some missing keys. If anyone's interested in these machines, let me know and
I'll forward your e-mail to him.

<Actually, on the downstream side of the adapter card you are tremendously
<close to an IDE interface. As I understand it, the IDE interface is
<premised on the commands that are required by the WD1002-nnn controller.
<zI have forgotten the exact model, but it must be near to the WD1002.
Incorrect.
IDE is the buslevel equivelent of the ISA16 card WD1003WA. The register
format, addresses of the registers are identical, the interface is also the
same save for there are only three addres bits and two selects(like chip
select) where the board would take a full 10 bit address and decode it.
The 1002 HOST interface gas a different address, register command structure
though there are similarities wbeing both from WD.
To do a IDE on kaypro you would need to do the 8<->16 bit translation
and from what I have here there is not enough addresses brought out to the
host adaptor plug. That means a CPU piggyback adaptor (GIDE is one case).
SCSI would be easier as a cpu interface but the SCSI bios is a nightmare
for the 5380 type chips.
In any case adding a hard disk to kaypro requires utility software, an
interface and BIOS.
Going the turborom route and putting two to three 3.5" disks is easier.
With 3.5" drives there is auto write portect on power down so you dont need
to eject the disks and with the that would be 2.3mb of available storage
plus the 360kb drive for compatability. I have one setup in such a mannor
with an old IBM PS/2 drive inside the case (I treat it as 781k hard drive)
and two drives on the front (3.5" and 5.25" 360k). For what I use the
kaypro for that's plenty of on line storage.
To do 1.44mb would require far more effort due to data rate and the fact
that DMA is not available so it would be hardware mods for floppy controller
and also big time bios mods.

I've been talking with a guy who has a Kaypro II and a Kaypro 16. I
I already have a Kaypro II and I'm not interested enough in the 16.
Anyone out there who might like these, he used them for several
years and just wants to see them go to a good home. Hmm,
maybe I need another storage space. Let me know if you're
interested and I'll put you in touch with him.
