New Apple Z80 cards

Submitted by CWJ_Wilko on March 9, 2017 - 12:09am

Has anyone seen these before? Just popped up on eBay for me, I've been looking at the cheapest possible solutions to getting CP/M on the Apple II:

Apple //c volume pot (did a bad one)

Submitted by CWJ_Wilko on March 6, 2017 - 4:57am

I've snapped my Apple //c volume pot when trying to 'repair' it. I have a nasty habit of making things worse before they get better. Does anyone know if there are any drop-in replacements? The plastic knob itself is fine, so I might be able to find something local or online that is close enough.

Does anyone know what resistance range that particular pot had?

I'll put in a request on the WTB forum just in case anyone has a genuine spare.

Use modern graphic file on Apple II

Submitted by evank on March 3, 2017 - 12:29am

Suppose I have a .jpg or .png or whatever, and I want to display it on a color Apple II monitor. Is there a procedure for this? If not, then what about converting the image into 40-column ASCII text?

II europlus crash after a few minutes

Submitted by falen5 on March 2, 2017 - 7:44am

Another strange problem
My II europlus crashes 1 or 2 minutes after I power it up.
If I keep at it (switching it on and off, reseating chips) it ends up not coming on at all, just a screen of random characters , as if there is a ram problem.

Spent a few hours last night and gave up. Just could not get it to boot at all

Refurb Apple II, how to get the disk II working

Submitted by greycon on March 1, 2017 - 11:06am

Have a pet project I go back to every few months - rebuild of an early Apple II. To date, PSU caps fixed, keyboard encoder chip issue fixed, and all good now, as far as starting up with no disk.

I have a couple of Disk IIs,but I don't know if they are any good. So, any suggestions on how to proceed? I could order a DOS 3.3 master from ebay, I guess, but I am pretty sure most of them would be worthless. I have a super serial card, so I believe if I had a known working disk II drive, I could burn my own.

Platinum //e - Softcard Locking Up

Submitted by grimakis on February 26, 2017 - 9:24pm

Hi,

I recentlty added an original Microsoft Softcard to Apple //e, Slot 4.

I've been having an awful of trouble with it. The system boots up, and many things works like Basic, etc.

If I type STAT, it returns the free space on disk A. If I type STAT B, it just locks up.

I have loaded other programs and they have locked up. Wordstar 4 locks up.

Is this card not compatible with the 65C02 timings? Do I need to get a different CP/M card?

Tecmar LabMaster AD211 Card

Submitted by macnoyd on February 22, 2017 - 4:04pm

Just got this card today with hopes of gathering as much info on the card as I can.

The TecMar LabMaster AD211 was one of the first multi-functional data acquisition cards for the Apple ][, though the card was mostly produced in 1980 to 1981. In it's essence, this is an 8-channel Analogue to Digital Converter Board. The Company was located in Ohio, USA.

The board's claim to fame:
