Super Serial Card Layout

Submitted by profdc9 on July 7, 2022 - 12:38am

For those that are interested, I revised Joshua Thompson's Super Serial Card build.  I revised it to be 2 layer rather than 4 layer, and to use a 1.8432 MHz crystal and Pierce oscillator rather than a self-contained oscillator.

The project is a fork of the original project at:

and the original is at

How to Record Sound while playing games

Submitted by Floppy Deep Dive on July 6, 2022 - 8:46pm

I'm new to the Apple IIe World so I'm hoping there is an easy answer.

 

I'm recording my gameplay and I have no problem recording video but how do I record the sound?

 

Thanks, 

FFD

Apple RGB color Monitor for Apple IIgs modded from 110 to 220V

Submitted by XLV2K on July 6, 2022 - 3:31pm

Greetings. I want to get an Apple RGB color monitor for my IIgs. They are very hard to find in the EU area, with EU 220-240V specs. So I was wondering, is it possible to get one meant for USA market, 110-120V spec, and mod it to 220-240V? What would that entail? I know I can use a step-down transformet but I would like to do a permanent internal mod. Is it possible? Are there any guides etc around? Thanks for your answers.

Making your Apple II useful as a *nix terminal

Submitted by bus_error on July 4, 2022 - 2:26pm

Hi all,

 

In my spare time, I've been messing around with getting my II+ talking with a Raspberry Pi running Raspbian (a Debian Linux distrib) as a terminal. To my surprise, I have actually carved out some success in doing so, despite the II+ being more or less barely able to do so.

Apple IIgs modem cable

Submitted by Hightray on July 3, 2022 - 11:58pm

I have what I believe is a null modem cable for my iigs. (It works with ADTPro) I got a modem that is 9pin. I can get this to work on my PC with a usb to 9 pin adapter. So I know the modem works.

As it is with the cable I have that is 8pin to db9 I cannot get the modem to work.

I want to build a cable that will connect to the null modem cable on the db9 side and re-wire it so it will work with the modem which is a db9 connector on it. It is a serial to wifi modem board.

Apple IIe ram issue

Submitted by tolderlund on July 3, 2022 - 9:08am

Hi, I have an unenhanced (I think) IIe with ram problems.

 

Booting with Closed Apple key pressed only shows "RAM:".

Shouldn't it display some numbers after RAM?

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.
