Microsoft Language Card

Submitted by mochatea396 on June 30, 2022 - 5:30pm

Hello group,I recently repaired a faulty Microsoft Language card that was locking the system up, reading disks incorrectly or not reading them at all. System worked fine with the card removed. The card had 3 bad TTLs. Both LS367s and the LS86. I replaced both tantilums as well. Now the card passed diagnostics and worked fine. Today I noticed it was doing the same thing it did before. Not loading programs correctly, locking the system up, intermittently not reading disks it just read. I removed the card and the system works fine.

Does Anyone Have a Spare Apple IIe Platinum Keyboard?

Submitted by Wiggle Wiggle on June 27, 2022 - 7:31pm

My Apple IIe platinum keyboard just failed on me. Does anyone out there happen to have a spare they'd be willing to sell me at a reasonable price? I'd really like to get back to gaming on my apple.

Are 8116 proper replacement of 4116 ?

Submitted by CedsRepairs on June 26, 2022 - 11:46am

Hey, quick one (for once)

 

In my Apple II Europlus i've got all RAM stock (with apple logo and copyright 1980)

Interestingly, one of them is not a 4116 but a 8116

 

According to specs, this is not a 12V/5V DRAM so I find it odd that it's mixed in the middle of 4116 from "the factory".

 

Could anyone more experienced than I am explain if these chips are indeed compatible/swapable ?

Apple IIc Plus A2S4500 Repair Help

Submitted by peterk on June 24, 2022 - 2:21pm

I have an Apple IIc Plus A2S4500 that isn't booting.  I've spent about 10 hours on troubleshooting and I've reached a roadblock.

 

The 65c02 CPU isn't getting a clock signal.

 

Looking at the schematics, the clock signal is generated by the 84 pin Cache Glue Gate Array (CGGA) 344S0607-A at UD17 Pin 44.   There is no clock output generated.

 

I'm also not getting any putouts on OE (pin 12) and WE (pin 14), which I belive should be generated by the CGGA.

IIGS Speech Synthesizer

Submitted by lee317 on June 24, 2022 - 8:20am

Does anyone know any specifics about the native IIGS speech synthesizer chip on the motherboard? I have two programs, Kidtalk and Smoothtalker that take advantage of this chip which basically work just like text-to-speech on macOS. 

 

Specifically, I'd like to know where on the board it is as I suspect it may be faulty.

CP/M on Apple IIe

Submitted by skate323k137 on June 23, 2022 - 5:25pm

Does anyone here do anything with CP/M on a IIe anymore?I picked up the GGlabs card, and have it running. The floppyEMU works in dual 5.25 mode (only revC of floppyEMU supports dual 5.25 mode). 

 

The only "good" disk images I have are the from the PCPI Applicard. There's really not a lot here other than the OS, drivers, and thankfully a utility to copy between DOS and CP/M volumes.

 

I'm curious if anyone has any other disk images that might work already.

DOS 3.2

Submitted by mochatea396 on June 22, 2022 - 10:43pm

I just finished ironing the bugs out of my Rev0 project and I’d like to get a copy of DOS 3.2. I’m running 3.3 but I’d just like to get a copy of 3.2.  All the images I’ve found are in a .d13 extension. I’m presuming this is 13 sector. Does anyone know where or even if I can find a dsk image of 3.2 that I can write with adtpro in a 16 sector drive? I haven’t tried but I don’t believe adtpro supports .d13 extensions. 

Thanks group

FloppyEmu DuoDisk Adapter

Submitted by MacFly on June 22, 2022 - 4:56pm

So, I have a FloppyEmu. Some may remember: the one with the 3D-printed Disk II enclosure... :) Using the FloppyEmu is great - so convenient. But, I don't know about you: some days, even with the "noisy disk" adapter I just miss the original flair of using real disks. Anyone else occasionally needs the original "Brrrrt!" and spinning disk sounds, wants to flip disks - and enjoy the nice "Klonk!" when opening the drives? :)

Having trouble inserting disks in dual disk drive

Submitted by gordonf on June 22, 2022 - 8:30am

I managed to clean up and repair an Apple IIe bought from a local owner. The progress of that is here:

https://youtube.com/playlist?list=PLG3aeorKmd7ajZHmgkbCI0g-k7w1ObaUc

I'm stuck with the dual disk drive not letting me insert some disks. This started after I removed the disk mechanisms from the case for retrobrighting, and it seems disks get stuck right in the middle on the leading edge.

I'm prepared to send this drive to an expert, but are there obvious things I should look for?

The drives themselves appear to read and write disks fine otherwise.
