Wimodem232 - //c & IIgs

Submitted by nick3092 on September 13, 2020 - 5:46pm

I picked up a Wimodem232 and cables for my //c and IIgs.  I can get everything seemingly working fine on the IIgs, but am struggling to get it working on my //c.  Which is really what I wanted it for, as I have a Uthernet II for my IIgs.  My //c is a ROM 255 with the "bad" serial timing chip instead of the oscillator.  But, it can transmit at 115200 baud using ADTPro no problem.  So I'm hoping thats not the issue.  Plus I've seen at least one person report the 255 worked with the Wimodem, but then again maybe their board had the oscillator fix done.  I can't say for sure.

Stuck key on a II plus

Submitted by fstark on September 13, 2020 - 10:10am

Slowly fixing my Apple II...

 

The keyboard didn't felt too good, and some keys were not working properly. I washed all the keys, and cleaned the switches with IPA as I could.

 

Keyboard is a Datanetics.

 

This resurected most of the keys. However I have two issues left:

 

First, one key is not boucing back normally after press

 

Second, sometimes, the following 3 keys are bad:

Return  : displays '-'

Left arrow / right arrow : display '5' and '('

Apple ][ plus power supply question. (Australian Voltage)

Submitted by PTB on September 12, 2020 - 3:09am

Hi Guys,

I've just found the old apple ][ that has been stored away for a long time (30 years) at my parents place. I want to do a full refurb on it and am currently in the investigation and cleaning phase. It was in pretty poor condition but am working through the process now. So much great information in this forum and elsewhere on the net.

Dead Apple IIe

Submitted by GrahamN on September 11, 2020 - 5:17pm

Looking for some advice.

 

I have an Apple IIe which is completely dead.

I have tested what components I can and found 3 faulty logic chips, 3 faulty ROMs and a suspect CPU. I replaced all of these , but still can't get any video output, nor do I get a beep with Ctrl G. 

I have checked the clock which is OK, but the CPU reset doesn't seem to be working properly - a scope on Pin 40 of the CPU shows a high signal with a fair bit of noise and this doesn't go low when the reset key is pressed.

Need Appli-card suggestions, please

Submitted by gottj on September 11, 2020 - 1:26pm

Hello, I purchased a Appli-card from a seller on eBay recently. The card is being shipped as of this post. In preparation for the arrival of the card, I have downloaded the Appli-card documentation, and several disk images related to CP/M for the Appli-card. One of the disk images (pcpi20_cpm 22_disk.dsk) can not be read by CiderPress. The accompanying "Utility Disk" image can be read. I'm hoping this will not be an issue when I copy the file to my MicroDrive compact flash card, and then make a floppy from that image.

floppy emu, Apple IIc rom3, and booting 5.25 images

Submitted by burpees_and_beer on September 10, 2020 - 5:38pm

New user here. Did some homework on Apple slots/drives and I know drive booting is complicated.

I have a IIc with 3.5" UniDisk. ROM is "3" and I successfully booted off the 3.5" media (Appleworks). I only have this one bootable floppy, and zero 5.25 floppies. To remedy, I bought the Floppy Emu kit, with IIc drive switcher. :-) 

 

My #1 Goal is to boot off 5.25 disk images. I'm not able to get this to work in any combination I've tried.

Apple IIe DynaComp 606-5001 PSU 120V to 230V?

Submitted by body_Infinity on September 9, 2020 - 11:03pm

Hi guys, has anyone been able to convert the earlier DynaComp  606-5001 PSU to 230 volt? Ive converted the later models successfully few years ago but have a couple of these sitting in my parts box waiting for some love. Have opened one up and all the caps / switches etc are rated at 250volt on the input side but have not been able to locate a schematic on this model to investigate further.

Any help/tips appreciated.

Apple IIc Repeating Space Character

Submitted by dhoggan on September 8, 2020 - 8:36am

Hi,

I've seen a few articles on keyboard issues on the IIc but none that match the issue that I'm experiencing. 

 

I have a IIc in good condition. Upon power up I get the usual "Check disk drive" message or, if a disk is in the drive, the disk loads. It is a UK model ROM 255 variant, so not the Alps keyboard.

Dual Video Output Device?

Submitted by mutant_pie on September 5, 2020 - 12:20pm

I was wondering if anybody ever produced a second video out device for the Apple ][ line.  By this I mean a device that put out graphics, mapping a different memory segment than the ones typically used for HGR and DHGR graphics.
