Trying to get ADTPro to work on Linux, without success yet

Submitted by insectorx on May 30, 2020 - 2:47am

Hi everyone.  I was able to get ADTPro to work earlier with an Apple IIgs, but I no longer have that machine (sold it during the lockdown to help pay bills).  I now have an Apple IIc and I'm not able to get ADTPro to work for me.  I've heard a lot of people say that it can be the cable (since I can't use the same cable as the IIgs), but I did order it from the apple2online store, so I'd assume it's the right cable.  I'm also using the same usb to serial adpter as before.  I had the same Linux distro on there as before, but now ive reinstalled it to troubleshoot, but I'm getting the same res

SOS on the //e?

Submitted by Timelord on May 30, 2020 - 2:23am

I'm curious, has anyone managed to run SOS on a //e with a large memory card? Given that we have 1MB cards commonplace, twice the RAM of the ///+, I see no system resource reason why a //e couldn't run SOS. I frankly have never tried to do that, but I would expect the boot block difference to get in the way of it working. 

 

SO, has anyone managed to run or port SOS to the //e or //gs architecture? I think that it has some advantageous features that might be useful.

Connecting Mac Plus floppy drive to gs

Submitted by nebular on May 29, 2020 - 1:28am

So I was able to salvage a GS from our local ewaste facility and I've been able to get it up and running with ADTPro (speediboot however doesn't work, and I seem to be only able to transfer over serial with pin 8 on the gs serial port empty). Trouble is it only had a 5.25" floppy drive, and I have no disks (and no money to buy them online). I do however have a couple Mac Pluses, a couple LCs, A Mac II, a Classic II, and an M0130 external drive (ewates has been good to me). So I'm flush with mac 3.5" floppy drives and I have a 20 pin ribbon to DB-19 adapter from the M0130.

SONY KV-5200

Submitted by Timelord on May 28, 2020 - 11:51pm

Is there any chance that one of you might have a repair manual or schematic for the SONY KV-5200 (1979 colour NTSC portable television)?

 

I have one that does not power on, at all, and it is a beast to take apart. Before I tear it down, it;d be nice to know where to look for faults. This telly use DC12V or AC120V, so perhaps something in the switching circuit is stuck? It also had a battery pack from the factory, but I see no reason why it would not work if there was no battery and it was not set in charging mode; although perhaps the charging mode circuit is stuck?

Need help with identification/classification of Apple II

Submitted by Stubby5000 on May 27, 2020 - 10:50pm

Hello all. I'm new here and just learning about the Apple II; forgive my ignorance. I have the opportunity to purchase an original II. It has serial number A2S1-22012 and is board revision 820-0001-07. It appears to have onboard Integer ROMs (only four??) and an Applesoft firmware card. The owner believes the mainboard was replaced at some point, but he's adamant that it's still a "real" original II. I have another contact who believes this is a II Plus mainboard in a II's case, making it clearly much less valuable/desirable. Below you'll find all the pictures I have of the unit.

AE Viewmaster 80 System Crashes

Submitted by Timelord on May 26, 2020 - 8:37am

I recently received a Viewmaster 80 (AE) card, and when I insert it into a slot, the system refuses to boot, and gives a repeating click from the speaker. Have any of you see that before? I am tempted to swap the PROMs, but I'm not sure if that is where the problem exists.

Language Card, Screen Filled with '?'

Submitted by Timelord on May 23, 2020 - 6:59am

One of my Apple Language Cards causes the following to occur:

 

The screen filles with the symbol '?' and the system locks up.

 

I have never seen this before, and I'm unsure what would cause it. Have any of you see that happen?

 

I suppose it could be a faulty 4116, but IIRC, I pulled the RAM and it still happened, and the Apple language card should work with the RAM removed.

General Questions [about the Apple IIe]

Submitted by diychris on May 22, 2020 - 10:28am

So I purchased an Apple IIe yesterday. It wasn't working, had horizontal bars across the screen. After much troubleshooting, replacing the 6502 did the trick.

I had an old Rockwell 65c02 lying around so that's what I put in. I'm not sure if that's going to cause any issues at all? I believe there are some differences between the 6502 and 65c02 but I don't know how those would relate to any issues with the Apple IIe.

ASCOMP

Submitted by BillO on May 21, 2020 - 1:49pm

Hi All.

 

ASCOMP seems to be a bit hard to find on-line.  User mutant_pie had once sent me a diskette with ASCOMP on it (about 4 years ago).  So, me, having an incredible sense of urgency, have finally gotten around to making an image of it.  Find it attached.

eBay Sharks: Beware new eBay freight costs!

Submitted by Timelord on May 21, 2020 - 4:11am

Here is a good example of a pure eBay shark:

He is asking USD$150+ for a //gs, and he put a US$INSANE freight cost on it. Even in the states, this is US$600, in a horrible condition, 'as-is, for parts'.
