Nice. You could also use just 1 SRAM and one ROM chip of sufficient size to cover the whole 64K range. Then, use one 7430 for each type of memory, using the inverted output for the /CS. You could make the 74138 outputs jumperable to enable different blocks of RAM and ROM. Or get more fine grained wi...

I will scan the FBasic manuals and send them along. Awesome, I'm very excited about that. If it's too big to email, or post here, I can send you an ftp login, or a dropbox link. Unfortunately my CP3 is having issues with the disk drives. I fired it up this week (first time in almost 30 years) and g...

How amazing that this is now possible!

Hi John,

That's exactly what I'm looking for! Number one on the wish list, in fact.

Shortly I will complete a reorganization of the disk image download section, and will add a bunch of new images, including this one, so hopefully things will be easier to find. @Danny: If you have source code for your enhanced Pic...

Welcome to the board! I must admit, I didn't have many games back in the day--didn't buy much software in general in those days--but I am looking forward to playing some of them as I organize and the existing available software and put it online. Thanks for your blessing on posting your creations. D...

Hi Grant,

This is super cool. Looking forward to seeing your progress. I think the backplane and 620 boards will be of general interest.

Hi Jeff,

Why don't you take some pictures, and post them in the "Projects" subforum. Most likely, your drives are fixable.
