Speaking of 850s --- I just picked up the $20 (plus $20 shipping) one on ebay. I have one in storage, but I'm too lazy to go digging for it- and I probally need two 850s. It's the last thing to complete this 1088XEL.


I'm going to play around connecting it with this:




which I also picked up from ebay - they are $16 for the whole kit as you can see.



I still can't believe no one has built a serial R: device to Wifi Module yet so we can all BBS on the A8s... or have I missed one?

In Topic: Hardware floppy drive emulators

I have an U1MB-SIDE2 combination and a SIO2SD. I am also seriously thinking about picking up an IDE+ v2.0 if they are still available. All of these allow a pretty decent degree of floppy emulation. However they don't--quite--do everything I would like.


My ideal scenario would be a setup where you can in some way create and mount a new floppy image of your specification in regards size and type without leaving the A8. I can envision something like a button to press that would freeze the Atari, bring up a menu on-screen whereby you specify and create an *.ATR image and then mount it. Another press of the button un-freezes the A8 and you can go on to use the new floppy image as if you had just latched a new disk in to your 1050.


Is there any hardware available that has this 'on the fly menu' type system for creating disks? I seem to think maybe the 'Black Box' did/does something like this? Any others?

The SIO2SD supports this:

If you are running into issues with what can fit in the drive bay opening you could use a custom faceplate similar to the one in the post below for the MEGA Speedy, which would allow use of the entire front edge of the main PCB. The upper port area could be enlarged as well if desired.

2716.... So looks like only a 4KB EPROM. It would occupy the 8K cartridge space, but would have data in half of it.

16k bit is only 2k Byte.

The important things about the right RAM chips are already told.


But... How is your experience with Atari 8-Bit? If you´re doing the first technical steps with such an old system, it´s better to do it step-by-step. First fix the defects, then think about expansions. There are a lot of new developments, some useful, some not. You will find a lot of infos here at AtariAge :)

True, but there is no point in purchasing replacement 4164 chips if considering a 256k upgrade. The 41256 chips are backward compatible with standard 4164s if pin 1 is grounded, and are often the same price or less.
