I am looking for a book I remember borrowing from the local library
about late 1980, early 1990
this what remember:
* BASIC programing (type-in listings)
* Advance Graphics
* Polygon graphics
* IBM
* "that's all folks" image on front/back cover
* BSAVE/BLOAD (I think)
* two or three flight sims ( wireframe, filled polygons, AI ), they
looked like Microsoft Flight Simulator 1.0 looking back
* wait press?
Is anyone perhaps interested in any of the following?
It's essentially the remainder of some of my earlier offerings.
I took the time to provide some details (that previously may
have been missing)
I intend to clear out the majority of it by mid-December
(around the 15th), after that it will likely be hauled off
to the recycler.

Hi folks,
I just picked up a Kodak Diconix 150 Plus portable inkjet printer. No
power supply or documentation, but it works fine. It appears to be a
variant of HP's Thinkjet (it certainly uses the same cartridges) tweaked
for portable use. Looking inside, it's full of Chinon ICs, and was
apparently made in Japan (from the baseplate).
This one needed some parts on the DC interface board resoldering, but
after that it worked fine.
Which brings me onto my question... Does anyone have any information on
this printer?
I'm mainly looking for a DIP switch table (annoyingly, it won't produce
a config print - just a test page). I'd also love to find some details
on the control codes, emulations and character sets it supports.
Also - does anyone know what the material on the printhead capping
station is, or if they're still available?
It looks like a cardboard or blotting paper pad with a plastic backing
card. This one is soaked in ink and looks like it could do with being
replaced. I assume it's to stop the cartridge from drying out?
I've put a HP 51604A (expired 2012!) cartridge in there, and it seems
happy enough.
Thanks,
--
Phil.

Well, the uengine would have to be considerably modified before it could be
used for a PDP-10 (e.g. wider data-paths); this version is very specialized
to the SD application (e.g. hardware CRC support, etc).

Hi folks,
A random facebook post made me dig out my model 4P which has never worked as long as I?ve owned it, it?s always just sat on a shelf looking cute.
Good old ASTEC PSU problem so I fixed that, reseated all the thankfully socketed chips and it burst into life. Sort of. I know it?s running because I can turn the brightness up to raster lines and see the pattern actually change when RESET is pressed. With contrast right up I can JUST see the boot logo appear while it reads the floppy.
None of the pots on the video board deal with contrast so I?ve got it out on the bench to remove and test the capacitors. What else can I look at at the same time? Someone else has already mentioned the transistors Q101, Q102 and Q103 (on the yoke board).
Screen pic: http://www.binarydinosaurs.co.uk/trs80Model4PScreen.jpg <http://www.binarydinosaurs.co.uk/trs80Model4PScreen.jpg> - you can JUST see the boot logo, I know it?s not screen burn because it does disappear on RESET and comes back again.
