342-0132 Keyboard ROM

Submitted by Paul19804 on February 22, 2022 - 10:35am

Have an 1983 Apple IIe (REV B) which has had the enhancement kit installed (CD, EF, VIDEO, 65C02).  It also has a new ROM in the Keyboard ROM position, simply marked "KEY."  How can I tell if it is a 342-0132 A, B. C, .... whatever?  And, really, what is the difference between the REVs?

 

Thanks!

Apple II monitor starting to blink/flicker?

Submitted by Thlorian on February 19, 2022 - 11:58pm

Hello all - I have an Apple IIe computer connected to an Apple II monitor.  I rarely use it but when I turend it on recently I noticed that the monitor started to blink or flicker every couple minutes.  I checked and adjusted the manual monitor settings but that did nothing to change this.  Is this something I can fix without having to open up the monitor for electronics work or soldering/desoldering?  Thanks for any info on this!

Apple IIe PowerOn

Submitted by GianDO on February 19, 2022 - 6:00pm

I had to take apart the original power supply of my Apple IIe to get it repaired, in the meantime I had to power my Apple IIe by taking the right supply voltages from an atx power supply which apparently works well. I plugged in and turned on my Apple IIe.The computer appears to be coming on, but a white screen appears on the screen which then disappears and is alternate with a black screen with white horizontal stripes, as if doing a test. What is the problem?

Thanks

G.

Is there somthing special about this software

Submitted by jwg1962 on February 18, 2022 - 12:54pm

Is there something special about this software, or is this just another eBayer thinking s/he has a gold mine because this software is unopened?  Someone at one of the vintage computer festivals was selling these about 10 years ago for $10 each and I bought a bunch of them.  Now I see this person listing them for hundreds.

Chip search

Submitted by baldrick on February 17, 2022 - 12:14pm

Hoping that someone here has some spares lying around.

 

They are all available at Unicorn Electronics, but I can't justify buying them because no matter how hard I try I can't get to the $30 minimum order.

Plus international shipping is killer unless it's first class mail or small packet.

 

I'm looking for the following:

78S40 1.3v-40v Switching Voltage Regulator (yeah I know it's available at Mouser)

6821 Periperhal Interface adapter 40 Pin DIP  (no longer available at Jameco)

8212 8-bit IO 24-DIP (no longer available at Jameco)

Search for keyswitch and keycap

Submitted by martin72 on February 16, 2022 - 5:27pm

Last week, I have found an Apple Europlus and I found out that  the keyswitch is broken and the keycap of character ' ? /'  is missing. So I am looking for these parts. I hope someone (in Europe) can help me with this parts. I attached some images of the broken keyswitch and I' ve removed the keycap next of this to show the type of keyswitch I search for. The last image is an example of the keycap I am looking for.

Disk II Interface Card - PROM P6 Replacement

Submitted by eggimac on February 15, 2022 - 2:55pm

HiI received a non-working Disk II Interface Card - I assume, the disk's ribbon cable was connected incorrectly… I compared the card to a working one by measuring the expected signals and swapping chips. A total of 3 ICs failed --> C3 (74LS323), B2 (74LS05) and B3 (PROM P6).
