Imagine the impact if Atari hadn't shoved an AMAZING 68030 on a 16bit databus.

Anyway, I'm pretty excited and wanted to post about it. You can see, comment and contribute to the code here: github.com/NeotomaDB/Da.... We'll try to publish as well, but if you'd like to contribute, let us know :)

The AY3 is very weird. On the Oric, they drive it from the outputs of the 6522 VIA port that normally scans the keyboard. I think the Spectrum +2 used a flip flop to drive the data lines.
I guess they all had problems with the non-standard interface not fitting on the databus.

Folks like @suzetteflantua.bsky.social, @ondrejmottl.bsky.social, @jacquelyngill.bsky.social, and so many others have done such amazing work with Neotoma, the DataBUS will allow us to build a broader community of practitioners, and also help improve our global coverage to address equity gaps.

Might work. You'd need to check databus timing to see if you need to separate the databus as well

Anything else on the databus that could be writing when it shouldn't and corrupting the data? (input buffer, bad RAM, bad ROM, paperclip etc.)
(or faulty decoding logic enabling one of the above when it shouldn't)

I'd like to think that the Neotoma DataBUS (Bulk Uploading System) represents a well designed software approach, that borrows a lot from software development, database management and from everything I've learned from @akthom.bsky.social about metadata standards and cross-walking in the geosciences.

I've got it working now. It helps if you pass a valid RAM address to a DMA controller 🤦 Now I just need a slight overclock to achieve the databus setup time on a 7.3728 Mhz Z80. I've never looked at overclocking, so where should I start ?

Looking at 65816 pinouts... they all seem to have an 8 bit databus.
I'd call it 8 bit, just like the 68000 is 16bit even if it has a 32bit ISA.

Definitely. My understanding is the only reason the 68000 started with a 16bit external databus was because forcing people to use 32 bit memory systems would have been crazy spensive in 1979.

A bunch of semi-modular synths (eg, ARP 2600) also have "mult" connectors, which are *exactly* a databus.
(They're just a few connectors -- three for the ARP 2600 IIRC -- that are wired together, so you can get more "copies" of a signal, to patch to "mult"iple places.)

And it's not just the wiring for buttons that's expensive. Lights, including brake and turn signals, remote mirror motor controls, and so on. I remember seeing that (I want to say...) Ford claimed savings of like $500 per car when they switched to a vehicle databus with 'smart' light controllers.

2. Neotoma's data model, developed by the late Eric Grimm is beautiful (open.neotomadb.org/dbschema/ndb). As a community curated data resource, we can support a wide range of paleo data, and serve it through open data services. The DataBUS means we can support a broader allied data community.

The problem is with read operations. I'm a peripheral, so I need to detect the host is in a read cycle, get the address, work out the response (not known in advance), and put it on the databus, all before the end of second half of the clock. I've got less than 8 instructions to do that in.

Your system doesn't have to be 100% #serverless. Check out an example of how @AzureFunctions can be used to perform a cleanup activity on an NServiceBus system using Azure Blob Storage to store blobs with the Claim Check pattern

i like the fact that i havea commodore 64,
but i’m not really interested having in the c64 for the same reason as most other people.
i wanted this thing for learning up 6502 assembly programming and hacking

![the bespoken “breadbin” build of the commodore 64 8-bit home computer.
unlike the nintendo 64 console,
the commodore 64 was so named not for the bit width of its cpu and databus, but for the address space it had for memory out of the box, 64 kibibytes of RAM ( addresses ranging from 0x0000-0xFFFF / 0-65535 ), it was common for memory addresses in 8-bit computers to have a width of two bytes, as with the apple ][ and the famicom, and most of them had components in circuitry allocated to take up all the 65536 address spaces for the cpu, but very few had it all allocated to ram on which rom and file data would be dumped for runtime at startup, as the c64 did, which was considered a very impressive characteristic of the computer, it was also the least expensive home computer for end-users of its time](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:ko44ggtzis2vzz3umqvqhu6v/bafkreia2efmjprz3vcvbbo2b7qtqe5zrrvrfwbnot3ebiwkpcyhbaueqxm)
