"IBM 4245 Printer, Models D12 and D20 Information Manual"
Second Edition (July 1986)
Good condition; hole-punched on left side and stapled twice. Could be
unstapled for automatic scanning.
Sent for the cost of shipping from 60074.
All:
I?m trying to build this 32-bit debugger program (using MASM on MSDOS 6)
and it doesn?t build anything past the first obj file. I?ve spent a while
playing around with this and I can?t readily see what?s wrong ? probably my
unfamiliarity with manual MAK files.
Can someone take a quick look at this and let me know what?s wrong?
Thanks!

They way you talk about this makes it sound like you're thinking of RL01
drives here. Are you aware of the fact that the RL02 will appear as five
drives to OS/8?
RLnA to RLnE?
Apart from that, I can't help you at the moment. My PDP8 systems are all
offline, and have been for a couple of years now. Although I have a real
8/A with RL02 drives, which do work.
Too long for my memory to be fresh on this one. Build have always been a
bit magical... :-)

I can tell you what a seller might have to say....
I had a case of a US buyer paying immediately for an auction he'd won, but
the postage specified was for UK delivery and there was a clear instruction
for international buyers to contact me prior to sending payment for postage
costs.
Needless to say, he refused to pay the extra few pounds for postage. But
instead of emailing me to arrange to back out of the deal so I could offer
it to the next bidder, he contacts eBay and PayPal and has PayPal freeze my
account because I'd allegedly ripped HIM off and didn't have the item I'd
auctioned!
I got the last laugh though. To get PayPal to reinstate my account I had to
provide them with a tracking number for the parcel....the amount I'd charged
for postage just barely covered surface mail to his location, which would
take 12 weeks to get there....!!!! LMAO!
Outside of a couple of non-paying bidders, that was the only time I've been
forced to leave negative feedback. But unfortunately, there are some real
aholes out there. :-(

Just north of the border. 3+ hours from Seattle with
good traffic and border lines. Just loading that much
stuff would be a major under taking. I did talk to a
local scraper here in Seattle but so far, He is not
interested.
I also have a complete Canon AS-100 that works.

Looking at those pictures, it seems the CIT-220+ keyboard is not all
that dissimilar in electrical design from the DEC one. It uses the same
kind of leaf switches but mounted in a completely different way, and the
leaves themselves don't act as electrical contacts on the CIT one, just
as secondary springs to push the thin contact plates.
If I remember correctly, the CIT keys look sort of like this if chopped
in half down the middle:
II-||-II
ICLKK I
ICLKK I
_CLSS _
|C LS |
--------
D
where C is the contact plate assembly
S is the main spring
K is the bottom of the key plunger
L is the leaf spring
_ is the place where the key plastic comes into two halves
I is the tab which holds the bottom half onto the top half
- is the bottom of the key
D is the solder tabs for the contact plate
| are the walls of the bottom part of the key
The leaf springs look like this if zoomed in, if I remember right:
side:
|
|
<
\
\
front:
_______
|_ _|
| |
| |
|_._|
/ _ \
|_/ \_|
I also worked out the complete key matrix for the CIT keyboard at one
point, I'll see if I can find it.

Now that OS/8 is running on my 8/A, RL02 system, I find I'm in
need of some more detailed help. Although I'm wading through the
900+ pages of the "OS/8 Handbook" (and the Device Extensions
document which at least addresses RL01's), I'm having a problem
adding device handlers as follows.
When I built the OS/8 image, it looks like I added only one RL02
partition (here is the current BUILD printout):

Doing a DIR shows "118 Files in 2517 Blocks - 1515 Free Blocks",
or ~4000 total blocks on the disk, which is also consistent with
one RL02 partition (A=40%,B=40%,C=20%) of the total 10000 free
blocks.
The RKB0: Diagnostic Pack has several handlers including:
RL2SY.BH (which is what I am using), and also RL20.BH, RL21.BH,
and RL2E.BH (not sure what that one is).
But any attempt to LOAD RKB0:RL20.BH (for example) causes SIMH to
stop with a "HALT instruction, PC: 20100 (ISZ 122)" message. I
tried removing R2SY: entirely (after setting SYS to RKA0:) and
still it won't work when trying to install other RL handlers.
Also when reloading it will only allow n=1 (platter) which I
suppose is correct. This may be why I only have one partition. I
did this over a year ago and don't remember all the details.
ANY ideas how to install the next partitions (R20B and C)?
Also, since I am planning on adding a second RL02 drive, I will
need (I think) R21A, B, C to appear in the active list. Is it even
possible to add a second RL02 under OS/8?
The C partitions aren't really necessary and are slow. I doubt I
will ever get close to filling up even the A and B's (8 Mb per
pack)....
Thanks for any help.

Have you looked at something like Digikey.com?
They list a bunch of pigtailed power connectors with ID and ODs
specified. largest seems to be 2.5mm ID and 5.5mm OD. Page 409 of
the online Digikey catalog.

I'm compelled to comment on the eBay topic.
First, I have to say that while it isn't bits and bytes, it is
relevant to the group. A lot of collectors of classic gear actually
get that gear from eBay. Every one of my 20 or so classic systems
came from eBay...
Anyway, I recently bought an item and received this in a form e-mail
>from the seller:
3)Am I going to receive a feedback from you since I paid immediately.
Due to overwhelming feedback request(we are all feedback junkies), I set
my system to Automatically leave POSITIVE feedback to buyer when the
following
TWO conditions are met:
i) item is paid. AND
ii) Buyer left me a positive feedback.
Of course, I was steamed about this. It's just not in the spirit of
how eBay is supposed to work.
I actually went to eBay to try to find a policy about this, stumbled
into the discussion forums and quickly realized that eBay, like Chuck
said, has all the integrity of "open-air bazaar in Marrakesh".
Tony's suggestion of keeping feedback private until both parties
submit feedback seems like a workable idea.
On the buying side, I also have a good suggestion - so much of the
buying on eBay these days is facilitated through PayPal (50 % or
better?). As a result, eBay knows when a seller has been paid. So
why not give automatic positive feedback. I mean, what really would
a seller have to say after the buyer pays?
It's amazing that in their recent revamp of the feedback system, what
they delivered is the best they could do.
-Matt
They now let you grade description, email responsiveness of seller,
etc. Hopefully this will improve the feedback score to a more
meaningful metric, but it will probably take a while to accumulate.
Particularly since the fine-grained feedback is optional.
