I'm back and first thing I did was the repair a not working SE/40 with success :) Clear picture, no strange noises from HD nor fan. New from September 1996 and last used on November 1998, just run as they say. This will be a perfect candidate for the Low End MAC on the Apple Talk network...

As I can get the ATI card cheaper then an 4MB memory upgrade I will go this way. I also checked the web but the numbers are for Windows and very different from what Apple reported... Generally I just made a calculation what can be displayed with 2MB and 4MB at 16 bits and seems 1280 can only...

Hi, I would like to get 1280 x 1024 resolution from my beige G3 (don't need 32 bits color), but with the 2MB standard it will not work. I can't find video memory upgrade for my beige G3 266, would it work if I add an ATI rage II PCI card (think it had 4MB) ? Br, Steve

Reading the "Guide_to_Macintosh_Family_Hardware_2nd_Edition_1990" I found some interesting info : 1. The /W/REQA signal from the SCC (only option for DMA) on the Plus, SE and SE/30 goes to PA7 of the VIA chip, So DMA is not possible on the old Macs. Only on the IIfx they go to the IOP...

Thanks for the link, I was wondering how to set the external clock option and found something in that thread. It's input only (differential buffer in-between), the signal also need a boost to be used by multiple other Macs. I would go for 1 external 1MHz clock and a good driver chip, it...

I know the AM85C80 SCC+SCSI chip also supports DMA for the SCC (and the SCSI), but this signal runs only to the GLUE logic VYI6508-2 gate array. Is there any documentation available about this chip how to program it please ?

I was reading some articles about ADB and it always says when you insert a device into a running mac you can destroy it ??? Only detail I found was a soldered fuse on the mainboard , can anybody confirm this, experience ? I would use an external power supply so this is no issue. On your...

Good news, works fine between the new LC475 and the Performa 5300. Now I have working system to measure on with the logic analyzer. My first ideas : - it's slow to todays standards, but for the 90 with only small files and minimal extra HW needed I would have loved it. - Also the slave...

Thanks for the doc. Some 30 years ago my jobs was to created CPU boards with the Motorola 68360, it's a 32 bit communication processor with 4 SCC onboard that support AppleTalk. I kept the original ceramic parts used for the development up to now, because I always wanted to build 'something'...

I found a video of "Adrian Basement" on Youtube where he also has the same issue is I have, but with the full PhoneNet network setup. He connected 2 Macs, made the correct setup but did not see the other computer in the panel as I do. He then makes a jump in the video where it works and says he...

I have both, and found this out the hard way that both are not the same. I got one Apple (cross) cable when buying the 6300 so I made a serial connection with Zterm between 2 machines, worked file. Took an USB to RS232 adaptor for my Windows laptop and swapped out the RS232 for RS422 driver...

My main goal is to write a "sceen-saver" program the runs on multiple Macs in parallel, showing a Amiga ball (or whatever) bouncing over all the screens. AppleTalk could be a solution to communicate to each mac where the ball will go next.

Thanks for the confirmation, I will have a good look at youtube how it's done as I know the HW is good (works with ZTerminal). Up to know I was not able to see the other computer in the list of AppleTalk control panel. Br, Steve

I opened up all 3 devices today (unfortunately the seller of the classics tried to power them up already ) and found some good and bad : One classic looked good no damage found, needs clean and recapping. Second classic has ugly battery damage, part of the metal is damaged and part of the...

Hi Tashtari, I think I'm in a similar situation as you where, I would also like to control my collection of Macintoshes from one single keyboard & mouse. But then also have the option to display everything on a single LCD monitor ... I got myself a second hand 8 inputs KVM for PCs with DB15...

Hi all, Can you connect 2 macs on an AppleTalk network with only a serial cable (as for a printer) or do you always need to the interface boxes ? I searched the internet and it suggest it would be possible, but not working for me. I do think it should not work from what I read in the specs...

Hi all, Got the LC 475 yesterday, 36MB ram should be enough, but only has 512kB VRAM, maybe will order the upgrade once back in stock. This will be my main development machine, a BlueSCSI will help to keep the noise down while having CD-rom support (iso file). I did run some benchmarks and...

The 630 has one advantage in it supports the COM slot, so I could add cheap(er) 10/100MB card to it. I found here : https://shop.onegeekarmy.eu/index.php/product/comm-slot-ii-10-100-ethernet-card. But then it's not in the supported list ... Don't know if there are any project on home build...

Thank you all for the response, my conclusions : - 630 has poor plastics (seen it on the 5300 also) and difficult to get in to, and I really want to get inside while keeping the case pristine ! - 630 can be expended with video and DOS cards, don't have any need for it yet. - 630 has CD rom...

Hi all, I'm just starting my Macintosh collection, as a child I could only afford an Amiga 500 and the Atari STE, but always wanted the Mac. Now 36 years later I can afford them but they are very hard to find (in Europe). PS I'm an old 68k electronic engineer so recapping or some other HW...
