Apple II+ Astec Power Supply - no Yellow RIFA, only a Red WIMA

Submitted by fritzycat on March 25, 2024 - 1:59am

Hello All,

I recently discovered my old Apple ||+ while cleaning out my father's workshop and I brought it home with me. Before attempting to power it up I checked online to see what I could find out about reviving this old tech, and was fortunate enough to find this community.

Internal power LED

Submitted by 8BitHeaven on March 22, 2024 - 11:31am

I was thinking about creating an internal LED to indicate when a ][+ or //e is powered up on the workbench.  I just want something clearly reminding me to turn it off before I start connecting or disconnecting stuff.  I anticipate using it with the case off and few cards installed.

Bank Street Laboratory card for the Apple II

Submitted by gmontag451 on March 21, 2024 - 4:55pm

I own two revisions of the Bank Street Laboratory card for the Apple II. This card allowed elementary school students to plug in different probes to measure light, temperature and sound; to emit light and sound; and to record and play back an audio waveform.

Apple III can’t tiping on prompt

Submitted by AppleWoz on March 20, 2024 - 2:53pm

hi guys, let me start by saying that I really have zero knowledge of Apple III, I bought an Apple III and replaced all the capacitors on the power supply, the machine turns on and the word retry appears, if I try to detach the keyboard it loops in a diagnostic ram (I don't know if it's normal), seeing some videos however by pressing ctrl + apple open an arrow appears and then I can write, I tried to press the same combination too and the arrow appears and you hear a beep but it doesn't allow me to write anything, it's a malfunction I assume, does anyone have any suggestions?

Focus drive size

Submitted by Wayne on March 19, 2024 - 2:43pm

I wondered how big a drive I could use on a Focus card. I already had a CF adapter attached so I tried my largest CF an 8gb. I let it format for a few hours and found it wanted to make 30 partitions with a lot of space left over. I deleted some, adjusted some sizes and partitioned it.

I’ve seen pics of these small hard drives on focus cards a few times. I’m interested in finding out which hard drive it is but I’ve had no luck searching

Hi Res photos of Super Serial Card?

Submitted by gmc on March 15, 2024 - 4:43am

Does anyone have (or can take) some hi res pics of a Apple Super Serial Card. 

 

I'm looking to make a replica of the original and so far have only found photos of the top side.  Have also found a schematic which should make things easier. 

 

I've tried building the simple serial card on github but there are lots of issues with is  so now on a mission to create a schematic/pcb layout of the original. 

 

The prices are crazy on eBay so thought this would be a good project.

Beta tester wanted

Submitted by jeffmazur on March 13, 2024 - 3:06pm

In search of a couple beta testers for a new ROMX product. Must have at least one Apple II (plus) clone - specifically those with the same chip spacing between the D0 ROM and LS138 (locations F11 to F12 = 0.25" or 6.35mm pin to pin). DM me with a list of your machines and what other boards are inside. Must be in US and have a few weeks to thoroughly test. If you already have a ROMX Text ROM that's a plus!

What is the general meaning of "No Beep" on startup?  I have just taken my Apple IIe (Enhanced) out of storage after 35 years.  Trying to make her work for my grandsons to learn by.  Any help out there??

Many Thanks,
