Appli-Card on enhanced Apple IIe

Submitted by BillO on December 16, 2018 - 1:03pm

This seems not to be working.  It's been a while since I brought up CP/M on either of my Apple IIe and I think it had the 'enhanced' upgrade done since that time.  Now on both of my enhanced Apple IIe machine the Appli-Card no longer works.  Is this a known compatibility issue or has mu Appli-Card gone south (so to speak)?

Apple iie - change in behavior after PSU failure/recap

Submitted by user2018 on December 15, 2018 - 9:14pm

I am new to this community - this is my first post!

I recently picked up a 1982 Apple //e.  When it arrived it powered on and was working fine.  Partway through the "Apple Presents...Apple" disk the PSU's .1uF 250V film capacitor popped.  The //e was still running, but I shut it down ASAP.  I've since replaced all the capacitors in the PSU, and the //e is running fine aside from these two peculiarities:

Odd Apple II+ Mod/Behavior

Submitted by 1978AppleII on December 10, 2018 - 12:29pm

Hi folks!

 

I have a friend who has an Apple II+ with a slight modification that allows them to boot from either the first or second slot.  (Slot 0 or slot 1)

 

Their goal is to be able to have a 16K language card in Slot 0 and a ROM card in Slot 1 - and be able to boot off of either.

 

While this appears to be working, they do not get an autoboot to Basic unless they have a floppy loaded.

 

I would have thought it would autoboot to the Basic prompt, but that isn't happening.

Restoring a Redstone Apple //e Clone

Submitted by Polymorph69 on December 2, 2018 - 7:07pm

Hi All, I videoed my "adventures" restoring an old Redstone Apple //e clone in October 2017 (!) and finally got around to finishing editing it for general consumption. Strap yourselves in, it's a bit of a long one... The video can be seen on my (new) channel here: https://youtu.be/m_-eu9YHbsk I know some of you will cringe at some of my restoration techniques, but please be nice as this machine was in a pretty bad state when I received it.

Inherited apple 2e

Submitted by Andrew minion on December 2, 2018 - 7:14am

Hi I have just been Given a Apple 2e computer with duo drive and monitor/software and manuals. I have set it up for the first time in probably 30 years. I am no expert on older computers. The Duo disk drive lights up for a second on both drives then doesn't do anything or load disks and also when I press keys on keyboard it keeps typing any letter I type. Any ideas why thank you

u-microcomputers u-dt i/o card documentation

Submitted by lcww1 on December 1, 2018 - 8:47am

I’ve just acquired a U-DT parallel digital i/o card for the Apple II - these cards were made in England by a company called U-Microcomputers. I’m wondering if anyone has the documentation for this card? I can’t find any documentation on the web.

Apple IIc US to European power?

Submitted by gschmidt on November 30, 2018 - 2:14pm

Hello all,

I'm looking for suggestions on how best to power a US Apple IIc (110-120v 60hz) computer when in Poland which uses 230v 50hz.  I know they make step down transformers for this purpose, but the frequency would still be 50hz rather than 60hz and that could be a problem.  So what is the best way to power this machine in Europe?

Thanks!

Videx Videoterm

Submitted by deltamind106 on November 26, 2018 - 9:44pm

I'm in the market for a Videx Videoterm 80 column card with the old mechanical switchplate for an Apple II.  There are a couple boards on ebay, but neither has any cabling.

 

I could certianly make my own cable if I know the schematic of the switchplate assembly.  I assume it is just a basic switch, but it is not clear which of the 4 wires is being switched.  If anyone knows anyting about this, I'd love to hear.

 

I'd prefer to get an authentic switchplate though.  Does anyone have one to sell?

Apple ii not Working / Dead needs your help

Submitted by deni85 on November 25, 2018 - 10:59am

Hey Guys,

I recently bought an Apple ii, it doesnt work, no beep, no video.

Ive already checked the voltages on the peripheral card slots, they were wrong.

It obviously had been repaired before with jumpers.(Photos included in the PDF)

I reseated every chip and checked the continuity on all jumpers, but it didnt work.

 

Thanks in advance for your help, Denis

Debugging Apple IIc: no beep, no nothing

Submitted by Doctor Zook on November 24, 2018 - 3:30pm

Hi Folks,

I have an Apple IIc that worked briefly before quitting. Now I get nothing: it starts up, I get a green power light and the drive spins, but nothing more. I'd love to get this running again. (I posted about this a few years back, but gave it up after a while, and just decided to pick this up again.)

So far, I have:
