Looking for help with a some Laser 128 machines

Submitted by Bill-Tek on April 18, 2024 - 2:51pm

I currently have 3 Laser 128 computers that are all exhibiting the same behaviour.  When I turn them on, I get a single beep and a screen displaying:

LASER 128EX/2 ROM Version 6.0

Any one out there familiar with these and where I might go from here to resurrect these machines?

Found a great book for Apple II copyprotections explained !

Submitted by UncleBernie on April 13, 2024 - 3:14pm

Hi Fans -

 

you might wonder why I'm interested in the topic of Apple I copyprotections at all - we nowadays use floppy emus using WOZ images, and don't need to "copy" copyprotected floppy disks anymore. But some people still might be interested in this topic. I am, and for very good reasons.

Apple VGA card - Ralle Palaveev v1.4 - Unrecognized

Submitted by Djoulz on April 13, 2024 - 12:19pm

Hello,

I juste finished building my A2 VGA card from Ralle Palaveev github version 1.4.

The board seems to work (I get a VGA output) but always in cyrillic and the utility disk doesn't recognize it !

Did someone had the same issues ?

 

Thank you in advance for your help !

Apple IIc FD Faceplate Removal for RetroBrite Process

Submitted by KLund1 on April 11, 2024 - 7:27pm

Hi,

  I got my first AIIc.  It is pretty easy to take apart and clean up.

But the FD faceplate does not want to release. This is after I have removed the FD from the case and took it's top cover off.

It has 4 flathead screws on the sides. 2 go into metal and they come out normally.

But the other 2 go into the black plastic disk guides. They just spin when I attempt to unscrew them.

What is the trick to removing these screws?

The FD white plastic is really yellow and should be retro-brited.

Wondering about needing a fan

Submitted by Wayne on April 11, 2024 - 1:07am

A long time back I’d pulled a lot of Acard SCSI to ide adapters from a bunch of old Macs. At the time I never thought to use them. They were attached to ide drives. Why use them when I had lots of SCSI drives? Later I thought of using them with ide to CF adapters. So I replaced the drives in a lot of SCSI enclosures with these. Then the only noise was the fan. Lately that’s been bothering me. Going solid state I’ve wondered about even needing the fan. I have a Century Corporation ide to SCSI enclosure that came with a CF adapter and never had a fan.

Help diagnosing my CRT for Apple II

Submitted by felangga on April 10, 2024 - 7:50am

Hello, I just bought this CRT with a smearing/streaking issue. Already recapped all of the caps and the issue is still there. Can you suggest anything to check? I believe this is a clone of Sanyo VM 4509, the schematic is here https://elektrotanya.com/sanyo_vm4509.pdf/download.html

Apple II plus , Startup issue

Submitted by nlee10 on April 7, 2024 - 7:40pm

 

I am having a startup error with my apple II plus. When I first sit down to turn it on everything works, wonderfully no issues at all. Now after wanting to swap disks/reset the computer with the on/off switch , the computer then boots up with a weak beep and a strange screen. If I leave it turned off for 30 minutes and come back then it all works again. It's only when it's that quick on/off/on. I'll attach an image of the screen. Any help would be greatly appreciated, and I'd be happy to answer any questions! Thanks :)
