  1. Glad to hear you got the display working. With regards to the keyboard, sometimes you can get the keys working again by applying a little contact cleaner down the key stem and working the key up and down for many repetitions (like a hundred or so). Other times you have to fully desolder the key switch and open it up to adjust/clean. If the key is not working at all, like in the case of your 'T' key, I suspect you are going to have to resort to the latter option and open up the key switch. Upon opening the key switch, you may need to gently bend some of the metal contacts such that they make contact again. Good luck, and let us know how you get on.
  2. Yeah I agree. If you look really closely you will see what appears to be part of a Videx 80 column card (or clone) in the bottom left of the bottom picture which lends weight to the unknown card not being an 80 column card (why would you have 2?). It might be an RGB card, but it is unlike any I've seen. It almost looks home-brew except its so well laid out.
  3. The original poster mentioned that this is an Apple II+ and this is also clear by looking at the keyboard and case slot access cutouts. There is no 80 column expansion slot in an Apple II+ either. As for identifying those cards - no idea sorry, there's an awful lot of 7400 series logic chips on there though...
  4. I would dispute this due to all my Apple's having their original RAM - with the exception of my 1981 Apple II+ which had one bad DRAM chip. In fact of all the vintage machines I own, the Apple II's are generally the best built and need the least repairs.
  5. Sounds like you have a marginal component somewhere on your motherboard that fails when it gets hot (which is pretty common). To find the culprit I would suggest using freeze spray in isolated areas of the board until the problem goes away. Then you can "hone" in further to find the faulty part. I would suggest starting with the RAM as that looks to be the most likely cause of failure.
  6. Yes, in fact System Software 6.0.4 has been out for nearly 2 years now: https://a2central.com/7396/the-source-is-strong-with-this-one-system-6-0-4/
  7. Yeah, I'm pretty sure the ebay auction said that it had been stored outside in a shed for many years; and it really showed. Even the box it arrived in had bits falling out everywhere. I was actually reluctant at first to put my hand inside it for fear of what I might find. Thankfully it was pretty much just dirt/debris and some remains left by spiders.
  8. Hi All, I videoed my "adventures" restoring an old Redstone Apple //e clone in October 2017 (!) and finally got around to finishing editing it for general consumption. Strap yourselves in, it's a bit of a long one... The video can be seen on my (new) channel here: https://youtu.be/m_-eu9YHbsk I know some of you will cringe at some of my restoration techniques, but please be nice as this machine was in a pretty bad state when I received it. Some of the techniques I used were new to me, so it was a bit of a learning experience as well. Cheers, Mike
  9. To be fair, this is *not* running on the 6502 - it's running on the ARM inside the Raspberry Pi. While it's very cool technology, for me it kind of loses the real essence of vintage computing. But each to their own.
  10. Erm, Linux on an Apple //e?!? All I can say is - good luck with that! The only practical way of running linux in an Apple //e case is to replace the motherboard with a Raspberry Pi (or similar)... no way will you ever get Linux running on an 8 bit 6502.
  11. That is good news. I was beginning to suspect your ADB chip might have been dead (which would essentially mean getting a new motherboard). Now that you have a working keyboard, have you tried running the self-test? With the extra RAM and the CFFA3000, you will be a very happy camper. You should be able to run pretty much anything, although a few software titles pretty much require an accelerator (e.g. Wolfenstein 3D, some demo's) to play properly. Keep your eyes open though, as Plamen of http://www.a2heaven.com/ is in the process of developing a new accelerator for the IIgs. Enjoy playing with your new machine! :-)
  12. Lack of RAM is definitely the problem here. Even 1Mb is tight for running System Software 6.0.1 - you can do it, but don't expect to be able to add many extensions. You may even have to hold the shift key while booting (known as shift-booting) to stop any extensions from loading. As I mentioned before, I highly recommend 4Mb as a miniumum if you would like to be able to run 16 bit software and not run into problems. Something like this should do the trick: https://www.ebay.com/itm/401095297373 Did you manage to get your keyboard working?
  13. Your IIgs is operating as expected. The IIgs is not like the Atari ST, it does not have an OS in ROM, but rather it has some toolsets in ROM that can be used by the OS. The message you are seeing is the result of not finding any bootable media. As the other responders have noted, you will need a floppy disk to boot (either 5.25" or 3.5"). The Apple IIgs can boot both 16 bit System Software (GS/OS) and 99.9% of all older 8 bit Apple II software/games. 8 bit titles are pretty much exclusively distributed on 5.25" floppies (with some exceptions). There are a very small number of 8 bit titles that don't work due to incompatibilities with the IIgs - they are so few though that you are probably unlikely to hit them for some time. After starting the machine, pressing CTRL-Reset (at the same time) will get you to an Applesoft prompt exactly like the older 8 bit Apple II's. OpenApple-CTRL-Reset will reboot the machine and OpenApple-Option-CTRL-Reset will start the self test (which should give you some confidence that everything is OK). If you don't have access to a floppy, you can bootstrap from bare metal using ADTPro and transfer a boot disk to get you going. To do this you will need an appropriate serial cable connected to a modern PC. There are detailed instructions on the ADTPro site for doing this. You may want to consider getting a flash storage device like a CFFA3000 or a Floppy Emu and a larger RAM card (4Mb or 8Mb is highly recommended) if you want to explore the 16 bit world. A great resource for the IIgs is the What is The Apple IIgs site. This should give you an idea of what is available. The IIgs is a great machine (my favourite) and I'm sure once you get up and running you'll learn to appreciate it too.
  14. Guys, Not sure if you know or not, but all of the nibble programs are available as a free download from the official nibble magazine website: http://www.nibblemagazine.com/nibble_disks.htm Hopefully that will save you the trouble of typing them in again. Cheers, Mike
  15. To add further support for the CFFA, there has been considerable effort in recent years to port 5.25" floppy games to run under ProDOS. For example: ftp://ftp.apple.asimov.net/pub/apple_II/images/games/collections/san_inc_prodos/ ftp://ftp.apple.asimov.net/pub/apple_II/images/games/collections/usotsuki_prodos/ So these can be installed and run from a hard disk too.
