Apple II

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. 

I am interested in trying to find out as much as I can about the Apple II siftware called AplleTel. This package was used to access videotex/viewdata services back in the 1980s. There was also a viewdata editing system with special keyboard and graphics card.I currently maintain the TELSTAR videotex service here in the UK (https://glasstty.com) and am hoping to archive as much videotex software as I can find.If anyone is able to help, I would be most grateful.

I was finally able to power on and test my Digital Apple RGB Monitor //. 

I used these years ago, and I could swer that shen put into monochrome mode, the phosphour colour was teal-blue. This one is very much green. It also has a colour issue in RGB mode, which may be related, where white is orange-y.

My first question: Do any of you recall these being teal monochrome; and were there different phosphour modes on them in monochrome mode?

I was looking into the PROM P5 that is on the 16 sector / track Disk 2 card.

So far I seem to understand what is going on there, except for this code snippet just at the beginning:

C600 A2 20 A0 00 A2 03

which disassembles to this:

C600 LDX #$20C602 LDY #$00C604 LDX #$03

So when the program is entered at $C600, as some authorative sources claim, the first LDX# does not do anything useful, because X is overwritten by the LDX #$03 before the first X value loaded can do anything else.
