Apple II plus troubleshooting help

Submitted by PeterKerr on September 2, 2025 - 1:38pm

I have been steadily working through troublshooting my new (to me) Apple II plus, but I've hit a wall and was hoping to get some troubleshooting help.

 

Background:

Bought an Apple II plus off a local seller on Offer Up. He last used it ~20 years ago and it had been sitting in his garage for the bulk of that time. There was a lot of surface corrrosion on the chip pins. I chased power, clock and reset . Replaced the 6502 and a handful of 7400 chips.  Deoxited everything. I also found I had a bad ROM so built the "ROM Replacement board"  and it now boots reliably.

Trying to get Apple Game Server 3.1 to run

Submitted by FHR on September 1, 2025 - 3:01am

I recently saw this app that allows you too not games from a serial connection, which in my situation would be great. However, when I run the application, I get an rxtxserial error. I've added the proper files in the right places and yet I still get this error

Super 5 (Teac) analog board (clonelike disk II)

Submitted by devorn on August 28, 2025 - 7:19am

Hi there,

I am seeking to repair an old 'Super 5' (Ei En Enterprises) floppy drive. This is a clone drive made in Japan and based on a Teca FD54a drive.  

This one may have been plugged in incorrectly a long time ago and has damage to chips on the analog board (one chip actually split open IC7).  

Issue with repairing is that the original manufacturer has removed the tops and labelling of almost every (except one) IC.

Replacement ports for the Apple IIe?

Submitted by braeburn on August 25, 2025 - 7:54pm

I've got an Apple IIe that I recently acquired and I've been working on getting it cleaned up and working and I noticed that all the ports on the back (specifically the composite video, cassette in and out and the joystick port) have some corrosion on them and I was wondering if anyone knows what the proper parts to order to replace these is?

Disk II drive issues

Submitted by SportBikePilot on August 25, 2025 - 12:23pm

Has anyone actually seen the stepper motors fail on these things? I've got one that I've cleaned up rail-wise, and the head-bang is very soft, and the thing doesn't step properly. I've checked it out with another analog board and it does the same thing.

 

With regard to the stepper motor, I know I can find them online (I looked), but what sort of realignment is required if its replaced?

 

Apprecaite any guidance. Essentially the drive does not seek. I confirmed motor speed is within tolerance.

Apple IIc first version: has anyone ever tried, or knows if it's possible, to install the Mockingboard 4C and the ZipChip 8000 on it? If you remove the reinforcement under the keyboard, can you close the case?

Apple IIe School Networking

Submitted by SportBikePilot on August 22, 2025 - 6:59pm

I recall back in elementary school a computer lab we had. It was all IIe machines, and they had a box attached to them with a ribbon cable. The box had LEDs and pushbuttons on the front, I seem to recall they said "SIDE A" "SIDE B" and "LOAD".

 

The things were all networked back to a main machine that had disk drives on it, and a more advanced box attached. As I recall you loaded the desired software disk into the main unit, and the workstations could then "load" off the main system.

IIe potential RAM issue

Submitted by SportBikePilot on August 18, 2025 - 7:49pm

I've got a IIe with logic board part number 820-0064-C. It appears to be a non-enhanced version.

 

When I hold down the apple keys and power on, it shows "RAM:" and sits there. ONE time I was able to get "RAM: F13 F12 F11 F10 F9 F8 F7 F6", but that doesn't much make sense. I can't get anything to boot properly either. Comes up to the Apple ][ display and the BASIC prompt but won't boot anything off of disk completely.
