I just got an old ][e that I'm trying to get running; I have a problem that I would like some help with: When I boot ANY disk (I'm trying as old as PRODOS 1.0.1) the PRODOS title screen comes up, then it comes up with this (centered on the screen): ** RELOCATION / CONFIGURATION ERROR ** It is NOT a platinum ][e It is running a duodisk through an Apple Disk Controller Card It has a regular Apple 80 Column/64K Expansion Card I have tried PRODOS AND DOS 3.3 disks...no luck I tried cleaning the contacts. I tried Ctl-both apples-reset and got "RAM:F13 F12 F11 F10 F9 F8 F7 F6" HELLLLLLLLLLLP!!! ---- ProLine: reb@pro-rebel (Richard Bryant) | 500th MI Brigade, Box116 Internet: reb@pro-rebel.cts.com | APO SF 96343-0091 UUCP: crash!pro-rebel!reb | 24 Hours, up to 2400 Baud ARPA: crash!pro-rebel!reb@nosc.mil | 011-81-3117-33-6301

In any case, it looks like your system RAM is fried. Try to find some 64Kx1 chips somewhere (get some sockets as well). Remove the original RAM chips, solder the sockets in their place, and plug the chips into the sockets. (I wouldn't want to directly solder the chips; a little static could ruin your day.) If you still have problems, maybe the MMU is bad. This is a custom chip, but hope is not lost; check some ads in Nibble. Somebody in there is selling IIe chips for something like $10-$20 each.

In-Reply-To: message from reb@pro-rebel.cts.com The message "RAM:F13 F12 F11 F10 F9 F8 F7 F6 Means the RAM chips in those locations are bad. Strange that seems like all of them on the motherboard. Try swapping them with those on extended 80 col card. UUCP: crash!pro-grouch!tomk ARPA: crash!pro-grouch!tomk@nosc.mil

Sounds like you have a memory problem. One of thge 64K chips on eith the motherboard or 64K card is bad. Boot the machine while holding both the open Apple and closed Apple key down. If the system is enhanced, which it sounds like it might be, the system will begin a self test. If a you get: RAM: 0 0 0 1 0 0 0 etc.... You have a memory problem. Pull the 64K card and try to boot. If you don't succeed in booting you're memory problem lies on the motherboard. Hopefully the 8 64K chips on the from or right side of the motherboard are socket mounted and can be individually replaced. If not, you could have a serious repair bill. The chips are NOT surfaced mounted, pick up a couple of 64K drams at a local computer store (they should be real cheap - if you can find them) and do the memory shuffle (replace a chip - boot computer - replace a chip - boot computer) until you locate the problem chips. If you're intelligentenought, the above error message tells you which chip is bad (denoted by the 1.) I forget which chips the numbers correspond to. _____________________________________________________________________________ | | | | Drew Rudman | 9600 HST Call 60 megs | | drewr@hpiosa.corp.hp.com or | THE CHARGE | | drudman@hpcc01.corp.hp.com | IBM/Apple 24 hrs/day | | Axe Slinger (#1)@The Charge | (415) 321-4713 - Menlo Park, CA | |______________________________|______________________________________________|

In-Reply-To: message from alfter@nevada.edu If one is replacing soldered in chips, the best way to remove them is CUT THEM OUT NEAR THE BODY OF THE CHIPS WITH DIAGONAL CUTTERS. Then remove the individual pins one at a time using a low wattage soldering iron (30 watt). This will prevent heat damage to the circuit card. Then solder in sockets as already mentioned.
