apple II keyboard messed up

Submitted by jrme421 on April 26, 2020 - 11:51pm

hi everyone, i recently unsoldered the key of my apple II but when put back on, the assignment of each key is different for example the space bar will type "@" or the keys "qwe" won't register at all. when i did the job the solder i used was obviously too hot, i just learned the hard way you cant use any soldering iron. 

 

sill i cleaned up all connection and i am positive no connections are overlapping or touching each other

Old DOS 3.3 Text files with .VSP and .ETH file extensions

Submitted by old_hitech on April 26, 2020 - 9:08pm

I found some of my old diskettes from the late 1980s and 1990 and found some files on my DOS 3.3 disk that are Text files ('T' file type when you CATALOG) that have the  "extension" .VSP and .ETH. For the life of me, I cannot recall what program or application was used to create these type of file names. I think the .VSP file is type of BASIC or other program file. I used to use ProBasic programming language, but I thought this was ProDOS-based - not DOS 3.3. The .ETH file type seems to be from some wordprcoessor.

Hi,

in "former times" there was the Apple II Documentation Project .

The curators used the mail address a2dp -at- brutaldeluxe.fr but this doesn't work now. Any ideas to contact them?

Diskette questions

Submitted by gmontag451 on April 24, 2020 - 6:03pm

1. I've just filled my second to last blank diskette! All my disks are double-sided, and I'm wondering if the Disk II uses both sides, or if I can safely cut a notch and format the back side to use it? (I used to do this with Commodore disks all the time.)

 

2. Is there a good source to order disks from? Amazon and eBay seem incredibly overpriced, or perhaps I'm just out of the loop...

AE RAMFactor Schematic

Submitted by Timelord on April 24, 2020 - 10:09am

I had a RAM|Charger, but IDK where I stowed it, or if it was stoleen. Do any of you have a schematic for the RAMCharger? I need the pinouts, at least, so that \i can build a replica.

Video: Apple IIe PAL Color Deep Dive and Repair

Submitted by llopis on April 24, 2020 - 10:02am

Should be particularly interesting to those of you in Europe, or if you want to know how they managed to get color on PAL systems from a computer that relied on NTSC interference to create color :-)

5.25" Drives for PC Transporter + KB Adapter Details?

Submitted by Timelord on April 23, 2020 - 11:15pm

As i recall, the PC Transporter required weird, proprietary AE drives, but it has an MFM connector on it. Is it possible to use normal MFM drives on the thing? Also, is there a schematic for the 5.25" AE drives so that i can build them?

 

I could also use a schematic for the //e KB adapter. I had a PC Transporter in a standard //gs, but I am considering putting one in my //e->//gs system, as an aux way to use soe old DOS stuff. (Essentially, to save some space on my racks.)

ZIP-II 4 Vs. Transwarp //e (Mk1) -- Pros and Cons?

Submitted by Timelord on April 23, 2020 - 9:55pm

I own both a ZIP-II (4Mhz) chip, and an Applied Engineering (original) Transwarp //e (also 4MHz).

 

I have always considered the ZIP Chip to be the better product, as it uses no slot. Wht pros and cons can you all list between these two that would dissuade me of this? 

 

These are in two, separate systems, and I haven't done critical benchmarks, but I expect the ZIP-II to be slightly faster by design, howeer, I do not know if the original Transwarp can be overclocked.

Apple /// stopped working

Submitted by Kingpin on April 23, 2020 - 7:26am

Major bummer!

 

My Apple /// isn't working properly as of today :-( It has been sitting idle for a couple of months now (since I last used it).

I've tried booting a couple of diskettes but the only one that worked (so far) was the Confidence Program (other diskettes loads some tracks and the freeze/hangs).
