G80-S v0.45t Stable Available for Download

While I iron out some of the details for the release of v0.50b and the v2.5g of TinyBASIC, I figured I better post an updated download for the currect version.  This is a stable pre-release.  And as such, not a lot is going to change between v0.45t and v0.50b.  I’m mostly just working on cleaning up code at this point.  If you’d like to check out the change log, it is attached below.  If you’d like to download the software, I’ve included it too.

I would have like to have already released the v0.50b by now.  But as we all know, sometimes life just gets in the way.  If you have any questions shoot me an email.  The Contact Us page  is your friend.

Also, there is still some availability of the PCB with the PLD option. I’m looking for a dependable supplier for these older parts. Once I do, they will become a more permanent option.

CHANGELOG – v0.45t

G80-S v1.0 Boards In Production

That’s right boys and girls! The first production run of G80-S v1.0 board has been ordered, confirmed, and are currently in production.

Some of you may be wondering what changes were made between the Beta run and the v1.0 boards. Well, to answer that question, not many. Firstly, and the most important aspect, the IEI line has been fitted with a resistor to VCC. This will allow SIO/DART interrupts if desired. It doesn’t affect current G80-S software. The other changes were simply cosmetic changes to the silkscreen layer. Everything should look pretty now.

Once the boards arrive I’ll get them checked for issues, but the layout hasn’t changed. So the only issues, if any, should be cosmetic at this point. (I had put quite a bit of thought into the board when designing it).

Also, I have designed and ordered a first batch of prototyping boards for anyone who wants to tinker with other hardware. This board will have breakouts for both the z80 bus as well as the PIO pins.  And will have a place for a Micro-SD card and a 1117 3.3v regulator. These changes will simplify modification for CP/M or testing with other hardware by allowing the user a way to expand the board while keeping the same footprint.  With stackable headers you could add quite a few items to the computer.  Just food for thought.

Happy Computing!

Popular Request: Microphone Pop Filter

Well, after suggestions from several viewers on my YouTube channel concerning the issues with my microphone, I have decided to break down and buy an el-cheapo pop filter.  Nothing special, here is the one I decided to purchase:

Double Layer Studio Microphone Pop Filter

It’s nothing fancy, but hopefully it will work until I have a chance to do research and invest in an audio interface and better microphone.  We’ll see.  But the good news is that it should at least help!  So look forward to future “hopefully pop-free” videos.

And for the record, it has already been ordered.  Whether or not I can hold off until it arrives before shooting my next video, that is a question for another day.  Although I do have a video I am REALLY wanting to shoot before too long.  However I have to do a little more work to get ready for it.  Maybe I could stretch it out until this weekend?

G80-S Micro Schematic and Source

I’ve been meaning to upload the source and the schematic for the G80-S Micro for some time now.  I just haven’t gotten around to it.  However, I had some time to do so this evening.  So attached here is the schematic, and the source code.  It’s the v0.25b version of the software.  Use them well.

Also, a link to the Source has been placed on the product’s page in the store for the Beta boards.  So if you want to buy a board, you can download the software there.  If you don’t want to buy a board, but want to play with my design, the schematic is here and the source as well.  Have fun!

New Website!

RetroDepot now has it’s own website!!!

This is something I haven’t toyed with since the days of Geocities, so try not to be too hard on me.  It has literally been two decades since I have thought about starting a website.

But until I get some Content on this site, please refer to my YouTube Page.  You’ll find a few videos to wet your appetite.  And hopefully get you in the mood for some Retro Goodness.

This is a new adventure for me, and I am not sure exactly where this is going to go, but it is my passion.  Just about every thought that crosses my mind is about the appreciation of technology that is obsolete or irrelevant to the current age.

So sit back, do a little reading, do a little watching, and enjoy.
