RE: Need Plastic foot for Performa 6115CD
Is the foot solid on top? Assuming there is enough clearance, could you remove the motherboard (if it's in the way) and drill a hole through the case and foot and use a small screw and nut and maybe washer on the foot to hold it in place?

This is the right front foot. I have thought about trying to Gorilla Glue it back on (there are metal tabs that hold the plastic foot on and the plastic broke at that point)... but upon reading the back of the Gorilla Glue bottle, it recommends against using it on polyethylene or polypropylene plastics. The question is: What kind of plastic is on our Vintage beige Macs... IIRC, it is one of those types? I'm pretty sure it's ABS, that's what the majority of computer cases and case parts are made out of. Fairly rigid but brittle, especially after being exposed to lots of UV. I didn't know that Gorilla glue would bond plastic and metal, I would assume that you'd have to use something like JB-Weld or an automotive adhesive. -- -- - You received this message because you are a member of the Vintage Macs group.

Macintosh IIsi help
Hi guys, I have two problems. I'd appreciate your input on either of them (or both). 1: IIsi video out I bought a Macintosh IIsi off eBay (with a PowerMac 7100/80) and the seller stated that both units booted to their desktops.The 7100 works fine (I've replaced the PSU caps already) but the IIsi does not play ball. I should point out at this stage that I use a (fairly modern) 14 LCD monitor with the DA15 to HD15 straight adaptor (no switches) and all my Macintoshes display lovely images on this LCD monitor - the LC, LC475, PM7100/80 and a couple of others. I have a 12 Apple monitor with the standard DA15 PLUG but it's been in pieces because I am rebuilding it with new electrolytic caps. So no luck there for now - it kind of got away from me when other more pressing things came to light (surgery, a hospital stay and a long recovery, early in 2014). I am aware the IIsi has a known 'issue' with certain monitors. Some VGA monitors cannot decipher the signal because it's sync-on-green which modern multi-sync monitors cannot decode. I just got a Signal out of range message although I did see a distorted display only coloured blue. So at least I know it is working (sort of). Okay, so my solution was to contact the seller and ask about this. He suggested I buy an adaptor. I purchased a Griffin Mac PnP and carefully cycled through all of the switch options, starting the IIsi and waiting for the video to appear then switching off and retrying. No luck. So I did some more research and thinking it was the internal video, I purchased a VGA card that fits in the Nubus riser on the IIsi. I first tried the straight adaptor (no display) and then I began the same process as before with the Griffin Mac PnP adaptor (again, no display). Then I bought a Griffin gView adapter but I need to get gender changers for it as the DA-15 connector on the gView is female and the HD15 is male. Alas, I didn't get that far as the IIsi suddenly breathed its last and is currently on the bench having its PSU rebuilt. Pesky caps again :-) I'm hoping that the gView will do the job - can anyone confirm this please? (gender changers ordered) The info with the gView does include settings for green-on-sync settings. Which brings me to my second issue... 2: IIsi PSU - Sony Model APS-06 [Apple PN 699-0567] PCB is labelled APS-06M I'm fairly sure that the PSU fault is due to (a) its age leading to (b) the leaking capacitors and (c) several capacitor lids imitating balloons. I have some stock of the regular smaller values but the big value ones need to be ordered. Low ESR's to be checked... As I was checking the PSU to identify the capacitor ID (Cxxx) on the silk screen and the value/voltage on the body of the electrolytics, I noticed extensive rot due to the electrolyte being liberally applied all over the other components and even some tracks under the green layer, solder side. Nothing too troublesome so far, however... There is, in particular, a blue, polyester film capacitor at C203 (Secondary side of the PSU, nestled near the power output wires) which had its marking all but removed, the case was split and in two pieces. Two other identical caps are at C104 and C251. They all have the value of 224V which puts them at 220nF but I don't know the working voltage. Can anyone help please? C104 is on the Primary side of the PSU, C251 is on the secondary side. As I'm in the UK and we roll with 240V AC @ 50Hz on our domestic supply, do I choose 250V or another value? The PSU is rated 100-240VAC 50/60Hz so it is pretty universal. Do I need to be fussy? I would appreciate your help. Also, 'V' isn't a tolerance rating used in film caps (only F, G, J, K M are used). Might 'V' refer to Vishay, the manufacturer? And finally, dimensions are an issue as C104 fits in an area about 3/8 wide ~10mm for the Europeans. Actual dimensions of the blue film capacitor are 7mm x 5mm (ex leads) x 4mm (Breadth x Height x Width) I have been on quite a few sites (some links are broken or dead) and Bomarc lists the pin out for the Sony APS-06 PSU on two pages. I've never used them before and since I currently only need those 2 pages, it's not worth my while to chase that up at the moment.

Re: Macintosh IIsi help
Once you get the PS fixed I would try the IIsi connected (through an adapter) to any monitor you have. I have found some LCD monitors will work with sync-on-green and specifically with the IIsi.

I first tried the straight adaptor (no display) and then I began the same process as before with the Griffin Mac PnP adaptor (again, no display). You need an adapter that separates synch from the green into horizontal and vertical synch. Nothing else but an old Apple monitor or other old monitor+adapter with synch on green support will work with the built in video. Google macintosh video sense pins for information on how Apple setup their old monitors so a Mac would automatically work with them. Each monitor only supported one resolution, which was chosen for each screen size so it would display 72 pixels per inch. 72 PPI was a common publishing standard and since Apple was heavily targeting the publishing industry with Macintosh and LaserWriter, they wanted what was printed to exactly match the screen and the only way to do that was to not allow a monitor's resolution to be changed. Apple eventually realized humans have the ability to see that two things are identical even when they don't appear to be exactly the same size - and started having multi-resolution monitors made for Mac. That of course was still before Display Data Channel and required adding diodes to the sense pin configurations. You have checked the PRAM battery for correct voltage and that it's in the holder the right way around? Many old Macs will not start up at all with a dead PRAM battery. Could also be It's dead, Keith. I'm a Dr. not an electrician! Pushing up the silicon daisies. Will only go *foom* if you run 10,000 volts through it. Pining for the fiords... In such case, time to hunt up another IIsi board or find someone who can attempt to fix the one you have. There is a hack to upgrade the little 12 Mac monitor to the useful resolution of 640x480 and expand the image to lose the large black border. No longer 72 PPI, boo-hoo. It's a difficult hack and AFAIK the how-to was only ever on the web in Japanese - and it's not much at all close to the 640x480 hack for the Color Classic and Color Classic II. The IIsi and SE-30 PDS are the same. They are NOT the same as the IIci cache slot which is actually a PDS, but for unknown bizarre Apple-ish reasons electrically incompatible with the same connector as used in the other two models. The IIci type slot was also used in the IIvi and IIvx, and also on CPU upgrade adapters made by DayStar and other companies for various other 68K Macs. DO NOT ever directly plug a card designed for the IIci type PDS directly into the PDS of a IIsi or SE-30. Bad things will happen, usually to the card but sometimes to the computer. The oddity is compounded by some dual adapter cards (mostly for the IIsi) that have one slot straight through and one converted to IIci style. That's so a CPU upgrade and one SE-30 or IIsi PDS card can be plugged in at the same time. *Usually* the two connectors will be labeled. On DayStar adapters the IIci style slot will be labeled cache card or powercache. For one specific model of video card, Daystar made a special adapter to put it first in line before the CPU upgrade because that one card would not work with their standard adapter. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com -- -- - You received this message because you are a member of the Vintage Macs group.

Google macintosh video sense pins for information on how Apple setup their old monitors so a Mac would automatically work with them. Each monitor only supported one resolution, which was chosen for each screen size so it would display 72 pixels per inch. 72 PPI was a common publishing standard and since Apple was heavily targeting the publishing industry with Macintosh and LaserWriter, they wanted what was printed to exactly match the screen and the only way to do that was to not allow a monitor's resolution to be changed. Apple eventually realized humans have the ability to see that two things are identical even when they don't appear to be exactly the same size - and started having multi-resolution monitors made for Mac. That of course was still before Display Data Channel and required adding diodes to the sense pin configurations. You have checked the PRAM battery for correct voltage and that it's in the holder the right way around? Many old Macs will not start up at all with a dead PRAM battery. Could also be It's dead, Keith. I'm a Dr. not an electrician! Pushing up the silicon daisies. Will only go *foom* if you run 10,000 volts through it. Pining for the fiords... In such case, time to hunt up another IIsi board or find someone who can attempt to fix the one you have. There is a hack to upgrade the little 12 Mac monitor to the useful resolution of 640x480 and expand the image to lose the large black border. No longer 72 PPI, boo-hoo. It's a difficult hack and AFAIK the how-to was only ever on the web in Japanese - and it's not much at all close to the 640x480 hack for the Color Classic and Color Classic II. The IIsi and SE-30 PDS are the same. They are NOT the same as the IIci cache slot which is actually a PDS, but for unknown bizarre Apple-ish reasons electrically incompatible with the same connector as used in the other two models. The IIci type slot was also used in the IIvi and IIvx, and also on CPU upgrade adapters made by DayStar and other companies for various other 68K Macs. DO NOT ever directly plug a card designed for the IIci type PDS directly into the PDS of a IIsi or SE-30. Bad things will happen, usually to the card but sometimes to the computer. The oddity is compounded by some dual adapter cards (mostly for the IIsi) that have one slot straight through and one converted to IIci style. That's so a CPU upgrade and one SE-30 or IIsi PDS card can be plugged in at the same time. *Usually* the two connectors will be labeled. On DayStar adapters the IIci style slot will be labeled cache card or powercache. For one specific model of video card, Daystar made a special adapter to put it first in line before the CPU upgrade because that one card would not work with their standard adapter. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com -- -- - You received this message because you are a member of the Vintage Macs group.
