What marker can be used with Infocom InvisiClues

Submitted by old_hitech on September 30, 2022 - 3:51pm

I just received the InvisiClue book for the Infocom Trinity interactive fiction game. I thought any highlighter pen would allow the clues to be viewable, but it did not work. I think I need a special kind of pen/marker to see the clues. Does anyone know which markers/pens work with the InvisiClues books?

 These are not common in Europe, but both have come into my hands.

So now I am reading and learning about them, in order to get the most out of them.

Imagewriter A9M0305 Manual needed

Submitted by Stargeezer on September 28, 2022 - 11:36pm

Evening Friends:

I recently picked up an Image Writer wide format printer, the A9M0305.

I have been searching for a manual for this printer.  It is possible they shipped the same one provided with  the letter sized, but my gut says there was a secific one for the wide format printer.

Anyone familiar with this manual?  Have a copy or pdf?

Thanks,

mark

Yesterday at a hamfest I bought a whole rail of NE558s.   These are used in the Apple ][+/][e joystick port.  Let me know if there's any need for them.

Help with Lost Screws

Submitted by andydiags on September 24, 2022 - 9:34am

Hi All,

I was repairing my Apple II monochrome monitor, and unfortunately misplaced the screws that go in the bottom of the unit.

The repair took longer than expected, with repacing caps first followed by new pots, took over a month.  Anyway, I placed the screws in a baggie, but now can't find it.  It's been 2 months and I was hoping it would show up but it hasn't.

 

Can someone please take a screw out of the bottom of their monitor and take some pictures so that I can get matching replacement screws?

Drive not working after being in storage

Submitted by stet on September 23, 2022 - 9:43pm

I recently pulled out a Disk ][ that had been kept in a drawer for several years. It was working when I put it away, but now it's not.

It powers up and makes the normal head banging sounds if I try to boot from it but then just spins the disk forever.

If I boot from another drive and try to read from it or format a disk with it, I get IO errors.

I opened it up and cleaned the head (which wasn't terribly dirty), but that didn't make any difference.

Pascal Adventure Games book

Submitted by gmontag451 on September 23, 2022 - 7:20pm

I've submitted my scan of the book "Programming Your Own Adventure Games in Pascal" by Richard C. Vile to the Internet Archive. Also included are three disk images which contain the adventures and all the data files in the book, as well as maps for the three adventures. In the book I've made notations to correct a few small bugs and for clarifications. 

 

The book PDF is here: https://archive.org/details/programming-your-own-adventure-games-in-pascal

SSC Revisions

Submitted by nick3092 on September 21, 2022 - 10:15pm

Maybe I'm crazy and going down a rabbit hole here.  But looking at an SSC card, I started wondering what the different revisions are.  I've seen people refer to them as revision A, B and C.  Maybe other letters, but seems to usually be one of those 3.  Most people seem to base that off the letter stamped at the end of the part number in the lower left.  And, there seem to be at least two variations of the Apple part number - 670-0020 and 670-8020.  Looking photos of these two part number cards, All the ICs appear to be laid out the same, discreet components all seem to be in the same spots.
