Does anyone know the voltages on the capacitors on a super serial card

Hello all,

I picked up a SSC cheap that needs some repair. DIP switches needed to be replaced and missing a cable. I noticed the disc capacitor at C13 was physically damaged and I’d like to replace it. The schematic shows it to be .01uf. Would anyone know what voltage these .01uf capacitors should be rated at?

BASIC usage of Super Serial Card

Hello all,

 I have setup my SSC on an appleII+ (clone), played a bit with terminal login and so on. The physical switches are set to 9600 bps, 8N1. It works well, however I decided to take it a bit further and catch some json coming from the other end of the SCC. I  have troubles integrating the serial data in a BASIC program. Let's assume the following string which is passed over serial:

{"test":"1234,56,78"}

 

and the following BASIC code to read this string over serial on the AppleII side:

 

10 print chr$(4);"IN#2"

15 j$=""

20 GET A$

Apple ProFile 5MB HDD repair

Hi all, 

 

I've recently got an Apple ProFile, 5MB HDD for the Apple ///, // and Lisa. It was not powering on so I repaired it - and as usual made a video! https://youtu.be/Vg4yNmrgVn0

 

Feedback and comments are welcome! I'll return it to someone who has a system capable of testing it soon - I only have an Apple // without the necessary card!

Do keycaps from 605-4115-0 RFI-style keyboard fit cherry MX keys?

Just curious if anyone here with a 605-4115-0 Apple II/II+ keyboard has tried the keycaps with Cherry MX keys. 

 

I know the  keycaps from later keyboards using ALPS keys are a little loose on Cherry MX stems.

 

Thanks,

Capturing Apple 2 composite signals

Hi all,

 

I'd like to complete my OSSC (VGA/Component/RGB capture card with HDMI output) with a composite input which works with Apple 2 machines. I know Apple 2 composite is a bit weird so I was wondering if anybody had any experience with any capture devices. I have a cheapo composite to HDMI which works-ish as in the signal is unstable with the Apple //e.

ReActiveMicro Phasor Sound crashes / freezes

I have an Apple IIe Enhanced, with a ReActiveMicro Universal PSU installed, an 80col/64k ram expansion card, and I am using a floppyEmu on a 5.25" 655-0101-D controller card (slot 7). There is also a SuperSerial Card installed (slot 2) and it works successfully.

Apple IIc drive woes. Bad IWM?

I'm having issues with my IIc drives. It reads from all the drives without issue, but not write to the internal, extrenal, or Floppy Emu in either location. Based on some forum sleuthing and my own investigations, I suspect that the issue is with the IWM. I'd love to have a second opinion on that diagnosis.
