P112 question - what can you run that uses 1MB of RAM?

Many many years ago, John Henderson, who ran Tall Tree Systems came by myComputer Faire booth and asked me if I had ever written any software thatused lots of RAM. I assumed that he was asking about qualifications for some project. I struggled to understand what he wanted to commission. Eventually, we got it straight that he was not looking for ANYTHING specific, he just wanted to promote RAM hungry systems, because he was designing MB and LARGER! RAM cards for 5150 ("JRAM"). What he wascreating was a system for "Expanded Memory", long before Lotus, Intel, Microsoft "standardized" it. He was apparently not invited to be part of that, in spite of being the primary such product actually ON THE MARKET, but he provided LIM support right afterwards. He came up with a Canon CX engine rasterizer add-on for his RAM cards, called JLASER. At that time Tthe HP LaserJet- (HP preferred to call them "LaserJet CLASSIC", rather than "MINUS"),and LaserJet+ were essentially text only, with 256K of RAM. Then he added [Canon IX?] scanner support with JLASER+ He came up with a way to use lots of RAM. Could a similar system be hacked together for CP/M? (He also wrote JFORMAT, which created disks for PC with 10 (instead of 9) 512 byte sectors per track, ability to use 96tpi "quad" drives, and ignoring the manufacturers warnings, to use 41 or even 42 tracks on 40 track drives. -- Grumpy Ol' Fred cisin at xenosoft.com
