Prototyping has begun. Working up a standard for using an SD Card is the end goal. But not just that. I actually have some other plans for a “project” to go along side the SD card. Not something that will be added to the overall computer. Rather something that will just be a fun project FOR the computer.
But to do this, I need more I/O. A lot more. Because of this I decided to add another 8255 PIO and a z80 PIO. The latter for it’s Mode 3 operation which will come in very handy with the SD card. Also, since we will be doing file handling routines, it might make sense to have a RTC so that we can determine the the current time. I had several ICM7170s on hand, and with the addition of a watch crystal and a coin cell, I should be able to rig it to work.
Progress is still a little slow due to work, but updates will be posted regularly. As progress is made, that is.
Also, changes have been made to the Product Pages for the G80-S computer to reflect some needed information. And a download page for the software will be added shortly. I ask that if any bugs are discovered that they be reported, and I will issue a patched version.
Do you have a project that you used the G80-S or the TinyBASIC 2.5g software for? Shoot me an email. I’d like to get a picture, and possibly do a write up about your project. Better yet, shoot a video, and I’ll add it to the blog crediting you! (With your permission of course).
Got a Website centered around vintage technology, software, or other hardware projects? Shoot me an email, with your website address. I’ll add it to an upcoming “Links” page.
