Hi there - me again|
Question: Is there a way to access the upper 128K in a 256K GS in P8 &
BASIC.SYSTEM - say as a 128K /RAM5 device?
If so - is it possible to disconnect the 64K RAM Disk (S3,D2) and use this
memory as usermem in AppleSoft?
Thanx 4 ya help & IIGS support|

Well, I may be able to help. I'm running a Laser 128EX with 64K main memory, 64K auxmem, and 512K on an expansion card in slot 5. ProDOS automatically sets me up as follows: S6/D1: internal 5.25" drive S6/D2: external 5.25" drive S3/D2: /RAM volume - standard size S5/D1: /RAM5 volume - 1024 blocks, 7 used I'd think (but can't say for sure) that ProDOS would either make the GS /RAM volume bigger than 64K (say, 192K or something) or make a separate /RAM3 volume in slot 3, drive 1. It's even thinkable that they'd make that 128K a separate slot 0 device, but unlikely. Just do an ONLINE call sometime and see what ProDOS does for you. As for your second question, that shouldn't be possible, due simply to architecture concerns. Auxmem is limited to bank 01 only, because of the bank-switching techniques used in the //e extended 80-column cards. Wait - do you mean just disable /RAM and not have to worry about conflicts with using auxmem for programs? Disabling /RAM is very possible; Copy II Plus does/did it all the time. Any copy of _Beneath Apple ProDOS_ should tell you how to do that. However, the memory "freed" by this process is only available to Applesoft by clever use of soft switches and assembly - not, I fear, for expanded program length.... Related to this, I have a question for the net: I have detailed my setup above; note that there are two RAMdisks in the setup. When using Appleworks 3.0, I get a 501K desktop. Upon closer inspection, I've found that the entire desktop resides in a file that takes up almost all of the largest RAMdisk on the system - not combining the two and doing some swapping. My question is twofold. First, it is possible to rename the /RAMx volumes to any name you want. If I were to rename my /RAM volumes, then put a disk online with the /RAM name, would AppleWorks run off of that disk? (Possible advantage, of course, being a truly huge desktop if you have a hard drive....) Second, is it possible to get AppleWorks to use ALL of my RAM - both /RAM and /RAM5? Also, does anyone know of a way to get Appleworks to segment big files for multiple disks? ---- ProLine: rhood@pro-gsplus | "Wherever you go...there you are."
