One time I burned my complete system folder to a CD and started up with it and got all sorts if errors because it wanted to write to different system files. Virtual memory wold be a big problem as well since it wants to use the hard drive that the system is installed on. It would be cool if someone could get it to work.

Re: IIci L2 cache, and other questions!
Since I have an empty PDS, are/where/is there any interesting alternatives to fill it with (that would still be compatible with OS 6)? The DayStar Turbo 030 Universal Power Cache manual (Version 2.0A) does not mention System 6, but the card will work with A/UX. They were made in 25, 33, 40 and 50Mhz speeds. Of course 25Mhz would be pointless in a IIci (but quite a bump for an LC or LC II) and 33Mhz is hardly any faster. 40Mhz puts it up there into IIfx territory and 50Mhz is just ripping along. The DayStar Turbo is system 6 compatible. Sonnet made an 040 card that seems to be System 6 compatable. Someone posted a URL to a page on the Sonnet site about it. We think it is compatible with system 6, no one has tried it as of yet. Marten -- Vintage Macs is sponsored by http://lowendmac.com/ and...

Re: IIci L2 cache, and other questions!
I think the standard was 32Kb. Can you get bigger sizes? Does it help? I don't think I've seen a PDS cache card. There were bigger sizes, 64K and 128 K, made by 3rd party vendors. I had a 64K that didn't seem to be any better than the 32K. Since I have an empty PDS, are/where/is there any interesting alternatives to fill it with (that would still be compatible with OS 6)? DayStar and others made accelerators for cache slot. All of the 68030 and 68040 DayStars that I have seen work with System 6. OK that sounds interesting! Care to share the *reason* why you did that? The reason for making the 32 bit clean ROM SIMM was to use it in SE/30 for OS 7.6 thru 8.1. The reason I asked was that I was having fantasies about making a bigger ROM with OS 6 built in. Like the Classic. What do you think? It would have to be a bigger ROM size and I wouldn't know how to make the IIci address that. You might consider instead, during boot, let RamDisk+ 3.2.4 automatically transfer System to ram disk. That causes all System calls to ram disk instead of hard disk and the machine will really *fly*. System 6 goodies are at http://home.earthlink.net/~gamba2/system6.html Gamba http://home.earthlink.net/~gamba2 BTW is there a way to readout the contents of the ROM's? Yes, with an app called CopyROM. Ok I'll go look for it. Cheers, John -- Vintage Macs is sponsored by http://lowendmac.com/ and...

Re: IIci L2 cache, and other questions!
Date: Wed, 30 Jul 2003 15:46:50 -0700 From: John Niven [EMAIL PROTECTED] where's my L2 cache? I looked on the MB but cannot see anything that I recognize as SRAMs. Where does it go? Is it a SIMM? I can only see a socket marked for ROM and what looks like a PDS slot (marked J13). The L2 cache is a card which plugs into the PDS slot. The local Goodwill store has several of them at $5 each. That's in Austin, TX. They seem to be fairly common. The biggest obstacle to getting one is likely to be the fact that their price doesn't justify the effort to stick one in a box and put an address label on it. Why do I have an empty ROM simm socket? I can see a set of 4 soldered in ROMs (made by Sharpe). There also seems to be a jumper switch. Maybe this switches between the soldered ROM and the simm socket for later upgrades? Yes, ROM is soldered down. The ROM slot is for later upgrades/mods which never materialized. According to Designing Cards and Drivers for the Macintosh Family, 3rd Edition, Table 1-1 the ROM slot allows expansion to up to 64 MB of ROM. Anyone know if that's a misprint? I guess if there are 26 address lines to the ROM slot, and the space is available in the memory map, then it could be correct. BTW is there a way to readout the contents of the ROM's? There's the obvious way. Desolder the ROM chips, and stick them on a chip reader/programmer. That's what I did. There is also a utility to do so. However, a list member emailed me the results the utility generated for the IIci and it differs from the directly read chips in several words. The ROM chips in both cases had the same part number, so either the utility does not do a completely accurate job of reading the ROM contents, or Apple revised the ROMs without changing the part number. If you're thinking about building a ROM SIMM for fun and frolick, beware that the circuit board needed is .050 thick. The thickness in common usage is .062 so it's a pain, inconvenient and/or expensive to build a ROM SIMM for the Mac II series.

IIci L2 cache, and other questions!
Just got my first IIci! I'm going to set it up as a OS 6 machine (it's currently running 7.5.5). It's completely disassembled now, I've washed the motherboard (some caps have leaked - I may have to replace them), and the case is being bleached at the moment, but... where's my L2 cache? I looked on the MB but cannot see anything that I recognize as SRAMs. Where does it go? Is it a SIMM? I can only see a socket marked for ROM and what looks like a PDS slot (marked J13). If I've got no L2, does anybody have some spare? I also need 24 inches.. sorry, make that 2 feet :-) Why do I have an empty ROM simm socket? I can see a set of 4 soldered in ROMs (made by Sharpe). There also seems to be a jumper switch. Maybe this switches between the soldered ROM and the simm socket for later upgrades? BTW is there a way to readout the contents of the ROM's? cheers, John -- Vintage Macs is sponsored by http://lowendmac.com/ and...
