Disk related chips and passives populated. It now defaults to disc mode in basic!!! This means it has found the FDC. Just waiting on an IDC connector for the floppy drive now. 😄

About 2/3 of the through holes have been cleared ready for sockets! What a seriously tedious job. And I'm getting some stubborn solder, too. 😖 Going to break out the desolder station to give that a try on the rest!! 😄

Any schematics will help with new cores for MiSTer, etc, so well worth having a hunt if you think you have any!
Do you have diagram schematics for arcade games? If so, please contact me.
Not interested in diagrams for CRT monitors.
Not interested in diagrams already available for download in the web.

I like the geometric layout of this chip from a Soyuz space clock, so I wrote a blog post explaining how it works. Although the Soviet Union cloned many Western chips, this NAND gate chip has some creative features. The clock is full of surface-mount TTL.

1/2: I wondered how feasible useful verlet simulation would be on the Jaguar GPU. I think, pretty possible. This is using 10.6 fixed point and some SIMD by having both X&Y packed into one register. Distance is via 16 section linear approximation.

Wow, that picture brings back memories! That was one of the first games I had on the Spectrum as well. May have even been the first...

Finally getting to doing Jaguar GD stuff again! Woo! I'm basically now waiting on things for the Lynx and NeoPocket GD's, so I've just laid up the programmer / tester device for the Jag GD. Things are moving ever closer. Albeit at a moderately fast snails pace...

Very pretty game. It was one of the reasons I upgraded from a speccy to an ST.

Now, this would be very nice too see! The Reboot guys have done a great job with the Bitmap Brothers IP working with Mike Montgomery, so it’s not some random fan request. It will happen given the go-ahead! 😄
Mr Braben, Sir @DavidBraben would you be able to assist at all in getting a limited & licensed run of your great game "Virus" released on the Atari Jaguar?

This keeps coming up. 😕 If you don’t support people who *create* the hardware, they will leave the scene. I know things can seem expensive, but seriously, when you have such small sales volume then margins do have to be high to cover R&D time and make the effort worthwhile.
looks like china copied the #mcwill kit and is even using the pictures from @Console5dotCOM to do it. this pisses me off to no end. guys please spread the word that this is not cool. @retrotink2 @RetroRGB @MyLifeInGaming @CastleManiaRyan

Custom chips designed with a pencil... 😮

We have it so easy these days with Verilog and FPGA’s costing just pounds each. Respin the chip in seconds! Crazy how much things have changed.
Engineers in the 70's and 80's were amazing. Hard to imagine they designed chips by hand.

And just for fun, a render of the most likely final shell candidate! All looks pretty nice, and fits in both Lynx 1&2 -- one of the design goals for this latest version of the cart. 😄

A few more Lynx GameDrive case variants sent for print. One of these will be the final design, with any luck! Most of the tweaks are to do with how the PCB is clipped into the case. I'm trying to do away with adhesive and rely on mechanical fixing if at all possible.

Quite pleased with the case and funky yellow LCD. Looks suitably industrial.

Very cool. This is something schools should be doing, we have a real lack of bare bones low level knowledge of computers in the world. It just seems second nature to me to know about bits and bytes, but many "younger" professionals don't actually have a clue. This scares me! 😆
If you are feeling nostalgic on the 40th anniversary of the launch of the Sinclair ZX80, why not build your own with a Minstrel 2 kit. (or a Minstrel 3 if you prefer the luxury of a ZX81 compatible kit).

MGC workshop project plan - a Z80 with 64k SRAM that is loaded at boot by an ATMEGA32U4 which also acts as a USB UART connection among other things. Slits in PCB so you can wear it like a badge and care edge expansion at bottom. $75 workshop cost target.
