Aftermarket hack to get 128MB on motherboard? I've heard rumors of those. Most only support 16MB. You sure about 128? ;)

I don't know why Commodore continued to cripple their machines with such poor memory access. No fast mem on the A1200 or CD32, slow access on the A4000/4000T, etc. Oh well, just a few in the long list of dumb decisions. Aside from the finger-slicing case and mediocre airflow the A3000 really seemed like the best of them!

Dave Haynie wrote a nice article a few years back explaining why the A4000 has such a terrible memory interface. I can't remember many of the details, but suffice to say Commodore were unwilling to spend money, and what eventually became the A4000 was essentially a stopgap machine, quickly put together, envisioned as an A3000+.

Yes thats why it ended up with crappy ide also. The memory bottle neck was due to them taking much of the 3000's PAL chips and combining them into the 'bridgette" chip,reducing chip count and saving money since there was almost no budget. Unfortunately brigette was slower than they wanted.
this bottle neck is not that big a deal since the motherboard only holds 16Mb,getting any quality accelerator bypasses the problem.
There were some guys who managed to hack 64M B onboard the 4000's stock simm slots,bu i could never get the guys who did the hack give me the info.
Remember one thing a stock 4000 with slow ram still blows a stock 1200 out of the water :)
At least the A4000 wasn't as crippled as the poor Atari Falcon with the 030 stuck on a 16bit Atari ST bus... That seriously must have be a quick work up design, which ended up in the final product due to lack of funds!?
