Apple IIe Platinum Keyboard Keys

Submitted by appleiiapple on April 28, 2021 - 1:10pm

I had no idea that 2 years could be so different...

 

Left 1987, Right 1986...

 

Anyone selling 4 keys for the 1986 version?

Double sided disks, but... how? And how to make ADTPro bootable?

Submitted by Dan in Vermont on April 27, 2021 - 6:33pm

This might be a dumb question.  I bought some new in box 5.25" Verbatim DS/DD disks for my Apple IIe, and they work great, but I am trying to figure out how to utilize the back side of the disk.  Someone at my work told me that I had to notch out a hole like the small square hole on the side on the opposite side, so I have tried that out and it doesn't seem to change it.

 

If it makes a difference, I took both of the drives apart and cleaned them up on the inside and the heads and stuff, and they both work great.  They are both the "Unidisk" variety.

Apple II GS ADB port issues.

Submitted by ZangLucarson on April 26, 2021 - 6:55pm

Hi all,Recently, my IIGS started having issues with its ADB port.

It started after swapping my battery holder and battery, which could just be coincidence, as I'm having trouble remembering if the keyboard worked initially after that, and I left it alone for about a week afterwards.

I double checked the battery and realized that a solder pad was missing from the positive terminal on the motherboard, it must have fell out when removing the original battery holder and I just didn't notice somehow.

Disk utility to move drive head

Submitted by zeropage on April 25, 2021 - 1:52am

I'm attempting to record the sounds of a Drive 2 in operation, and I'm wondering if there's pre-existing software to move the drive heads on command. Ideally I just want to move the head from the first track to the last.

Euro IIe PSU - Options/-12v?

Submitted by lilwashu on April 24, 2021 - 3:10pm

As detailed in another thread I have a euro IIe which had a RAM failure and also has a burned transformer in the PSU, so I need a new PSU. I like the look of the Reactive Micro one but the price is a bit high and the shipping to UK is almost the same again so that's out.

I've done some research and it looks like the IIe doesn't use the -12V rail at all unless a Unidisk is connected - is this true (I have a spare Mac LC II PSU that does +-5v and +12v and would be a great fit if so...)?

Mystery card with two 16-pin connectors

Submitted by jlandahl on April 21, 2021 - 12:21pm
This unlabeled board for an Apple II computer is one I'm curious about and haven’t been able to identify.  It has a 16-pin connector at the front and another at the back that I don’t understand the purpose of.  The only manufacturer marking I can find is the number “252” at the bottom edge.  Some of the chips have 1982 date codes.  I dimly recall picking it up for $5 at a computer store clearance sale decades ago because it reminded me of my Synetix 294KB SSD (solid state drive) card for the Apple II Plus.  That was because of its shape and the large number of chips, with

Success - Apple II+ clone lives

Submitted by Stargeezer on April 21, 2021 - 8:59am

Hi folks,

I just wanted to share my excitement and joy at the successful restoration of an Apple II+ clone.

It seems to be working well now.  Nothing really magical at the restoration.  Cleaned it up, retro-brighted the keys and pulled all ICs and de-oxed the sockets.

That last step seems to be a big help with video issues the machine originally had.

Cheers,

Mark

Apple IIgs ROM 03 system bad error

Submitted by Verault on April 20, 2021 - 4:22pm

I have two ROM 03 Apple IIgs systems that gives  error "SYSTEM BAD 06010000" When I run the built in Diagnostics. From what I looked up it seems to be an issue with the built in SERIAL IC on the main board.Is that correct or is the issue something else? IF I disable the modem port in the control panel and add a super serial card will the system work as intended sans the on-board serial components? Would that create a functioning machine?

IIe - Crashes After Power On

Submitted by lilwashu on April 18, 2021 - 7:45am

I've recently acquired a PAL IIe with Disk II card and extended 80 column card and for an hour after arrival it was working fine including a self test, writing floppies with ADTPro, etc - it then froze when running ADTPro and hasn't worked since. A list of what I have done so far:

 

1. Power cycle after initial freeze (didn't respond to soft reset) resulted in a white screen, no beep.

2. Removal of 80 column and Disk II card resulted in beep and command prompt, froze shortly afterwards. Reboot results in screen of garbage.
