@@MartinPiper6502In 1980, 4116 DRAM chips were US$10/piece, according to an advertisement in the January edition of Interface Age. Therefore over a thousand chips would've been required at an inflation adjusted cost of US$40,000.
Very cool 👍 I wish they had added something like that to the VIC chip. Just imagine all the cool things you could do if you didn't have to spend so much CPU cycles on moving characters and color attributes around. The next best alternative is the REU with it's DMA transfer, but unfortunately it never really caught on back in the day. I think it's most popular use was by pirates using it to load a full disk side into memory and then write it multiple times to multiple drives to speed up disk copying. 😅 Why not add some ~100nF decoupling caps to all those logic chips?
I'm really glad I did not have to solder this, all the ICs have at least one CL05B104KO5NNNC decoupling capacitor, the RAMs have two each. But they're so tiny I can hardly see them with my eyes on the PCB. :)
@@Kobold666 I don't think the REU was too expensive, it was around US$169 in 1987 for the big 512kB version, but there was little reason for anyone to buy one, no killer games, just some simple demos and GEOS. IMO Commodore should've hired some talented people to write a few killer games for it, then they'd have sold like hot cakes and other developers would've latched onto it. But of course the Amiga was already starting to gain traction at this time, so maybe not.
@@MartinPiper6502 yeah, everything was more expensive back then. A 1541 drive was around $200 at the same time and don't forget SNES and Genesis games cost $50-$120 each back in the early 90s.
Is this dual port RAM or does the graphics board and C64 access in turn based on the clock phases? I've always been fascinated by multi-CPU systems and how they overcome bus contention and in accessing shared RAM
2mb of ram on a C64 type of computer would had been insane in the 1980's... ..but can it run Crysis? :-P I guess this project is one of those "because I can" types...
Exciting stuff! :)
Your trust means a lot to us!
Wow that is super cool. You have some mad skills there! 👍
Cheers :) It keeps me busy.
❤The C64 lives forever ❤
Very nice update! Would be cool to get a MegaWang 2000 TE at some point.
I plan to make PCBs available to purchase, but they will be an expensive thing to own.
Imagine the cost of that 2MB board in 1980 🙂
Astronomical, and many chips.

That would be around US$450 is today's money?

Great work Martin
Thanks :) I just like tinkering.

@@stupossibleify normal single port RAM. The write access happens during the vertical blank period when the video doesn't read RAM.

I have a plan :)
