What's on your workbench???

[adason]

Just curious about what the other guy's workbench looks like?
Well it's pretty sad but here's mine.
leftovers, trashcan fodder, blown speakers Etc. Etc.

OK we could call this thread the wall of shame. Be a man, step up and show us just how twisted you are.

What if I do not have workbench?

Lol...then you've landed on the wrong thread! This is the 'whats-on-your-workbench' thread...🙂

Hi adason,
lol!
Then you're either in the garage, or you have deep, lasting trouble with your wife!

How many layers Suzy? I am guessing 6? Two power planes and 4 routing layers.
I see it’s a new design by your date stamp. Wondering why use old z80 tech in today’s world? Need to re-create a legacy design for code preservation reasons or support, just curious since I enjoy looking at your skills 🙂

Four layers. Inner layers have vcc and gnd pour as well as signal. It's compatible with an eighties Australian computer called the Microbee, done with a different video memory scheme that's been rattling around my head for a while. It does 16 colours and 640 x 264 graphics. It's all just for fun.

Amazing, a Z80, a 6545 for video, some hitachi sram 62256 ?, maybe a 8255 and a BASIC Rom… so much memories.
One question, why so many TTL glue logic ? There are more than the few ones required to operate the chip listed above.
Are they more chips under the keyboard ?
Could you tell us more about this very neat board ?

Not an 8255, a Z80 PIO. The glue is to run the screen mostly - 640 x 264 in 16 colours.
