RAPID 4 – Extended Cut

This is the extended version of the RAPID sheet. Since space is limited and I wanted the RAPIDs to be a single sheet, easily read in under a minute I have created this page with things that I cannot fit in the sheet- links and images!

This is not a comprehensive representation of what happens in the Discord- there is too much going on to capture it all. Hopefully this will provide a bit more context and important links to the events covered in the RAPID sheets.


COCO Bring Up

* COCO: bring up via cassette port!
* TCH – FSK encoder allows FN to create audio on the fly (cassette input)
* using CMOC as a compiler to build coco disk images
* CMOC is a 6809-generating cross-compiler for a large subset of the C language

Proto Board designed by hideehoo (ChrisT)


Atari 1090

I think the silkscreen work is done. Part numbers and/or component values have been added. I’ve also added ground planes to most of the unused areas of all layers. I ran into an issue with parts availability for the 3.3vdc voltage regulator so it’s been changed. Also, because of voltage drop-off concerns, with the voltage regulators, almost all of the components take their power from the unregulated +10vdc from the 1090/1 board via the two voltage regulators. The advantage here is also a reduced parts count and, since you need a 1090/1 anyhow, I don’t think it’s a big deal. I’ll review it on and off over the next day or so. Unless I find an issue to change, this is the board I am ordering.

FujiNet Library Sample Apps

Fenrock: I've made httpbin an example application for using network library in fujinet-apps. 
It's working on Apple2 and Atari. Interestingly the CRLF handling isn't working (you can see 9b in the atari 
hex dump output, and in A2 it's 0d but I'm specifying LF (0x0a) in the call to network_open, so I need 
to debug that). The code does:
* JSON queries (which are GET but in JSON mode)
* Adding http headers to requests
* network_read to show doing a normal GET (I will add a network_http_get as a proxy next release).

AppleWin Emulation

The new FujiNet-PC (aka virtual fujinet) has been integrated into AppleWin a popular Apple2 emulation app for Windows (runs in Linux and OSX via wine). This is a huge step forward for Apple2 FujiNet develpment- now developers can work on FN apps without having any physical hardware. The AppleWin app recognizes a SLIP device in a slot, and the SLIP device connects to the FujiNet-PC running on the system. They transport the SmartPort packets over SLIP between AppleWin and FujiNet.

It was a close collaboration between OliverS and Mark (fenrock) in discord….

fenrock: I’m pretty close on finishing the AppleWin SP over Slip though on FujiNet-PC and AppleWin sides. Getting and replying to requests. Just debugging a few things.

fenrock: there’s tons in there that I feel can be reworked to SLIP only, but I won’t touch it now, just getting enough until everything is in one code base as I see @apc is busy in this area too, so don’t want anyone having a merge hell

Oliver Schmidt: Exactly! When (and only when) both SP-over-SLIP is established and the FN-PC merge is done, we should have a close look and refactor the IWM stuff in a way that makes sense for both the existing CBus code and the new SP-over-SLIP code!

That wraps up this January RAPID. I’m trying to keep these short and concise, which is hard given the amount of work and collaboration going on in the Discord. If any of this interests you we are always looking for help in any way- coding, testing, building, documenting- consider hopping onto the Discord and just say hello.
