@CalumDouglas1 Wow, haven't seen those chips in a long time. The first company I worked for had several TMS340x0 TIGA graphics cards they used for CAD work. Very impressive back in the day.

I put together a short video as a demo of the new sound cartridge I'm working on for the Acorn Electron and BBC Master. Still lots to do, but it's coming along nicely now.

For the first time the Plus 1 Mini expansion unit for the Acorn Electron is available through Tindie! To celebrate, there's 5% off everything in my Tindie store until the 22nd using code RAMTOP5.

@UB1UB2 No tax, no MoT, no safety gear, wearing a hood. The bike is probably stolen and being used to steal other bikes.

@0xC0DE6502 Hmm. If you're doing that I suspect what's left are just those games that have less than wonderful joystick code.

[ramtop-retro @RamtopR]

@0xC0DE6502 My memory is not super wonderful, but I do remember returning results from the ADC conversion immediately seemed to work better than emulating the delay caused by the Plus 1's ADC chip.

@BirdyBro_MiSTer @AnnatarTheMaia @VEsoterica Where did I mention user perception? The question was about emulating or simulating hardware, which absolutely can require accuracy to very small time scales (ie, functional replacements for vintage ICs).

[ramtop-retro @RamtopR]

@AnnatarTheMaia @BirdyBro_MiSTer @VEsoterica FPGAs can be functionally identical to the real hardware, ie, all the outputs are the same down to sub nanosecond timings. Software emulation can't do that.

@commodoreihs Such sad news. CATS had an amazing reputation when she was there.

[ramtop-retro @RamtopR]

@ChuckHellebuyck Agree, it's simple to use and surprisingly powerful.

[ramtop-retro @RamtopR]

@lauriewired Fun fact: the 68020 was put back into production due to demand from aerospace customers, so you can buy brand new ones today.

@TheLightSpeedz Nothing 'influencers' say can be trusted, for a multitude of reasons. I've owned several printers that got positive reviews but were complete trash in reality. Doing your own research using direct user feedback is the only way to not get ripped off.

[ramtop-retro @RamtopR]

@NathanBuilds You're assuming everyone has the same needs. Anyone who requires a large format multi-colour machine for commercial use basically has to choose this or a Prusa XL, and the H2D is a lot cheaper than an XL. I wouldn't buy either, but I don't need that capability.

[ramtop-retro @RamtopR]

Delighted to be able to put the ElkSD64 back on sale as I've found a source of suitable CPLD chips. Because ebay is busy self-destructing I'm listing these on Tindie instead as a test.

@UncleJessy4Real @Creality3dP Creality's lack of quality control is a shining beacon of consistency in the 3D printing industry's sea of change.

@geerlingguy $700 is probably correct. AMD doesn't want to sell consumer GPUs in any real quantity, they'd rather use their limited fab allocation for more profitable AI and datacentre products instead. Good business, but terrible for gamers.

[ramtop-retro @RamtopR]

@ZombieHedgehog_ $299 for an enclosed CoreXY is a still an absolute steal. I seriously considered ordering one, but Elegoo is quoting June for availability in the UK and that's just way too long.

[ramtop-retro @RamtopR]

@geerlingguy @BigTreeTech Thing is, Bambu's magic is in the firmware. The hardware isn't all that special, so a replacement board will turn the P1 into just another generic Klipper (presumably) coreXY.
