Apple II lid styles and mesh strips

Submitted by bradleyb on October 31, 2022 - 2:04pm

My II+ needs a lid, and there are currently three for sale on ebay, all slightly different styles. I suppose it probably doesn't matter greatly, but is there a way to match the "correct" lid for my specific apple?

This first one:

Very early Apple II PSU blows fuses

Submitted by deltamind106 on October 29, 2022 - 7:07pm

I'm working on a very early Apple II power supply, serial number in the 3000's.  I want to restore it to proper working order, with a minimum of fuss to keep it reasonably original and historically accurate.  Although I did have to drill out the 2 rivets that Apple decided to use to keep us safe from ourselves.  I suppose I could replace them after I'm done.

RamPak 4gs Utilities

Submitted by Beach71 on October 24, 2022 - 8:35pm

I have a RamPal 4gs card and the utilities disk. Yup, paid for it I don't know how many years ago. I just trie dto run it on my GS, but none of the software seems to come from Irange Micro and files mentioned in the manual are not on the disk. Strange.

Does anyone know of a source for the utilities that came with the card?

Thanks.

Connecting Apple III to FloppyEmu

Submitted by MacFly on October 24, 2022 - 5:12pm

I was having a bit of fun with my Apple III connecting it to a FloppyEmu (and to a normal Disk II drive). My Apple III only had the single internal drive so far. It really needed an extension...

Since I wanted a convenient and safe solution for the connection, I made a simple adapter. It's basically the Apple III equivalent of the D-SUB to 20pin IDC adapter for Apple II, which BMOW sells with every FloppyEmu. Sure, Apple III with FloppyEmu is certainly a niche application, but hey, so is any retrocomputing anyway. Maybe someone else is interested after all. :)

MacEffects Apple IIe Keyboard LED issue

Submitted by clockchip on October 24, 2022 - 1:42pm

Hi everybody,

is it normal that the MacEffects Apple IIe keyboard has so little brightness (I don't even see it turned on).

Can anyone confirm this who also has this keyboard, or do I have a defective keyboard. (maybe they soldered the wrong resistor on the board)?

regards

Apple ][ Joystick Dimensions A2M2002 or A2M2012

Submitted by ManOfScience on October 23, 2022 - 2:22pm

Could anyone with an actual Apple ][ Joystick and a caliper post some actual dimensions?

 

Would love an acutal Apple ][ Joystick (A2M2002), but like other nostalgic devices from my youth, their value has now risen above my budget.  Therefore, I am switching to assembling icons of those memorable devices rather than the devices themselves.

Apple II Plus with unknown board rev. 820-0044-00?

Submitted by jherrm on October 18, 2022 - 2:38am

Hi, I'm new here but have been a lurker for years. I recently received a nice Apple II Plus that had a few cards (including a Videx Videoterm and MS language card), and I just noticed this logic board's part number is not documented online: 820-0044-00

 

The only 820-0044-XX revisions I can find info on are: 820-0044-01, 820-0044-C, and 820-0044-D, with the main source being the defacto  The Apple II Circuit Description:

Testing 80 column card?

Submitted by gmc on October 17, 2022 - 6:16am

I've got a 80 column card (820-0066) off eBay for my Apple II that had a faulty 74LS245 chip which I replaced. Is there any software I can use to run a full test on it to see if there are other issues (RAM?)

 

If I run PR#3 it goes into 80 column mode so looks like it's working, but wondering if there is a more indepth test I can run?
