So at the suggestion of intric8, I purchased a mem68k board from mkl on eBay. Got the second to the last one, I don't think he has any more on eBay right now.
Installation was easy, and WHOA! Totally bitchin' having 8 megabytes of RAM on an A1000 with no intrusive modifications. Found out that my A1000 has had the "wire chain" ground modification done to it (and that it's missing a LOT of screws on the inside
Anyhow, the 8M RAM showed up immediately and the machine is MUCH zippier now! Looking forward to spending more time with it running some programs it previously wouldn't run due to running out of memory (like NCOMM).
Thanks for the suggestion, intric8! Totally worth the effort, money and time.
