Lobo 5.25" Drive info?

Submitted by desertrout on November 6, 2021 - 10:43pm

Does anyone have any experience with the Lobo 5.25" drives for Apple II's? I have one here that is non-functioning --- in fact, plugging it in to the Disk II controller prevents the system from booting at all. I'm quite certain the cable is connected at both ends properly. I'm having a lot of difficulty finding any information about these drives at all... and I also can't seem to find any information on why plugging a drive in would prevent a system from booting. Any thoughts?

Franklin Ace-1000 Beeps (sometimes) with a Garbage Screen

Submitted by DistantStar001 on November 6, 2021 - 3:57am

Just picked up a Franklin ACE 1000 and I have an issue.  The computer powers with a screen full of garbage (various random characters, many inverted, with a few random solid and checkered blocks mixed in), and will beep on power-up most of the time (every so often it's silent).  Usually hitting reset will cause it to beep, and typically change the garbage on screen (fewer characters, or more spaces, lots of exclamation points).

Reposting this here for anyone who might be interested in beta testing the Yellowstone FDC and meets the requirements, but doesn't follow BMOW that closely.

Franklin Computer Disk Interface Card

Submitted by tolderlund on November 4, 2021 - 1:18pm

I got this disk interface card together with an apple IIe some years ago.

There was no documentation with it, although I don't think I need one.

The card was not working, but I found that the 74LS373 was faulty, and after replacing it, the card works.

 

Notice the jumper pins just to the left of the blue connector?

I am guessing this means that the card can handle 13 sector disks and 16 sector disks.

Without a jumper the card displays the screen below when booting (or when using PR#6). See photo 3.

How awesome is that?

Problem Apple //e board displays horizontal bars and graphical glitches

Submitted by DistantStar001 on November 2, 2021 - 1:34am

So I've had this Apple //e problem board for some years now.  The board itself has some really bad sodering on all the RAM sockets, as well as the sockets for the EF-ROM and the S02.  The fist RAM chip has a lot of bodge work (one of the pins seems to be free floating even) but as far as I can tell, everything is connected to what their supposed to be.  The 'new' sockets appear to be double swipe, so decent quality.  However, it still won't boot.

Apple //c Diagnostic V2.0 Found/Preserved

Submitted by nick3092 on October 31, 2021 - 1:18am

Someone over on Reddit seems to have located a "new" version of the Apple //c diagnostics compared to the only version on Asimov.  This supports the newer ROM 3/4 versions, as it has an extended memory card test.  The existing version on Asimov seems to only like ROM 255 machines and forces you to have a serial loop back cable.  This one lets you skip the serial test if you don't have the cable.

Newbie looking for a IIe joystick

Submitted by montreal on October 30, 2021 - 4:55pm

Hello,

I'm really happy I have found this Apple II online community.

I've recently acquired an Apple IIe (non-enhanced) which I'm restoring.

Many of your posts are really helpful !

 

Would anyone know where I could find an Apple IIe compatible joystick?

Universal Serial Interface Card Model J13-A for Apple IIe

Submitted by tolderlund on October 30, 2021 - 8:27am

Some years ago I bought an Apple IIe which I'm now beginning to restore.

Along with it came some cards, but without any documentation.

One of these cards is this serial interface card.

Does anyone have any manual or documentation or information about it?

 

Googling it I only found one place where another guy also asks about it, but no answer except about the Super Serial Card which this is not.

Apple IIc keyboard problem

Submitted by papalapa on October 30, 2021 - 6:46am

Recently I bought an Apple IIc with german keyboard and after some days of use the RETURN, ENTER and ARROW UP keys stopped working. I opened the Apple IIc case, unconnected the keyboard flat cable and visually checked for some damage, but all seemed to be correct. I applied Contact Cleaner  (zero residue) to all the switches and after re-installing the keyboard again all the keys started to work.

 

Today, after a couple of weeks using the Apple IIc, the problem  has come back.  What can be cause? Flat cable or keyboard controller chip maybe (which one in this case)?
