It crashes on the emulation? That's good intel, it looks like it is a real bug in my code, and not some weird timing issue. Excellent news. > By the way, how does one quit out of the app once you reach the console window Click the mouse. You can also abort playback by clicking the mouse (you may need to leave it pressed a couple of seconds, I check the mouse when I don't have anything else to do, + once every 300kb of flim, so if you are playing on a real MacPlus, it can take time...)

I tried removing the ROM, and it didn't make any chimes at all. Put it back in and chimes of death again. So probably not the ROM. Strangely, when the RAM is removed, it makes the normal Rominator boot chime but simasimac as well. Is that supposed to happen when RAM is removed? None of the tabs are broken and I'm sure they're pushed in correctly.

Simasimac/garbled video can also be a loose ROM SIMM, though probably not with death chimes - but still worth a try. It has to be very tight in the SIMM socket and some ROM SIMM sockets have become temperamental over time - you can use a rubber band wrapped around the ROM SIMM and lopped into the front groove on the board to keep it tight in the socket. Try with matching RAM SIMMs in bank A only first, make sure they are tight in the SIMM sockets. If any of the plastic tabs on the SIMM sockets are broken, use a rubber band to pull them toward the front of the board to keep them tight in t

Great to hear it's just the emulation acting up. FYI the Adrian SE/30 file also crashes with the emulated Plus, but it just freezes (no unimplemented trap error). Tested on 6.0.8 and on 7.5.3. It always happens here in my case: Both Star Wars SE/30 files work fine on my emulated Plus. By the way, how does one quit out of the app once you reach the console window? There's no mouse cursor and the Mac doesn't respond to Cmd-Q or Cmd-W... Is it meant to work that way or is vMac misbehaving again?

You should add the exact part number from the board to the schematic sheet and the name.

Thanks for you enthusiasm! The cracks are due to emulation. Here is the adrian video playing on real hardware (Mac128K with memory and scsi upgrade) : https://youtu.be/CVmNsYHbwIo For comparison, the SE/30 version: https://youtu.be/MlvKIY-kRIc I lost some time trying to get things running smoothly on minvmac before I discovered it was an emulation problem. It makes a lot of testing harder, but if it was simple, it would not be fun. However, I have crashes on real SE/30, as you can see in the second video. The first time it

Words simply cannot describe how stunned I am that this is now a thing. Literal movies on a classic Mac, and now with sound?! Keep up the good work Fred! This is definitely the Mac's new killer app! I took the liberty to do a bit of testing. Nothing proper and since most of the collection is in storage, I gave it a go with mini vMac. Playback of Plus files on an emulated Plus works great. No video glitches to report. But there seems to be something wrong with the audio. Maybe this has to do with the emulation but I figured I'd better let you know. Basically there

Go for the simple stuff and assume RAM first; the seller could have thought the death chime indicated a reasonably healthy board. I'd also check your cleaning around the caps check no traces were removed with your Q-tips.

Are you sure that is has a BNC connector?

Thanks for all the suggestions. Great! I found a kti KE-5T hub. Looks like it should work but I can’t find useful info. I found the manual but I’m not sure it wil work.

Chime of death means that it can read the ROM. So the RAM may be the problem. I had a SE/30 board that chimed with a chime of death and the problem was one very corroded F258 chip. Could be your two chip RAM too. I would buy 8 1MB chips. How many RAM chips did you install? There is a documentation in the web, how to upgrade the RAM in macs. http://akarchive.digidesign.com/support/docs/memguide.pdf

Yeah, that's another sensible option; those usually seem to be a bit more expensive and a bit more unwieldy than an AUI transceiver, but are also useful in more circumstances (if you have something with only 10Base2, for example). Depends how general a tool you want

I use an old 10 Mbit hub (CentreCom MR820TR) with bnc und connect this with a rj45 cable to my router. Then you only need a bnc cable and perhaps a termination resistor.

Double post - argh.

It shouldn't be bent, I'd say you just got lucky and the pin in question PST3 which "indicates the internal execution unit's status" conducted some signalling that perhaps wasn't so important. If you have a retractable lead pencil (with the lead removed), this serves at the perfect pin straightener, otherwise very gentle plier work is OK MC68040UM.pdf'

So, I just decided to clean the board on my Quadra 700, and to prepare I lifted the processor. As it was coming up out of the socket I noticed that one pin looked to have been purposely bent over (see photo). I’m curious as to why this was done, or if it’s a fault that somehow never caused any issues? if it does need bending back then I’d appreciate any tips on doing tha.

That 15 pin port you have there is called AUI. It's a standard port for attaching different physical layers to. What you need is called a 10BaseT (or "10Base-T" with a hyphen) AUI transceiver. They're sometimes listed on eBay as "RJ45 AUI transceiver" instead. They aren't expensive; this person in the UK is selling some for under 10GBP each; you may be able to find similar more locally: https://www.ebay.com/itm/164514800709 They were extremely widely-used for years, so you shouldn't have too much difficulty in finding one for reasonable money .

I just scored a farallon PN594-TN networkcard for my SE/30. I would like a solution to hook it up to UTP rj45. Do you know any affordable solution? Preferably with an adddress in Europe? Thanks!

I recapped a very dirty SE/30 motherboard, pads were so dirty it took 3 q tips each to get the gunk off, by far the dirtiest board I've ever recapped. I got this computer locally from a guy, and he showed pictures of it powered on with simasimac, not the thick horizontal bars type, but the one with lots of tiny lines. I haven't tried turning it on before I recapped it, and didn't ask him if it chimed. The computer didn't have any simms onboard, so I ordered a Rominator and 16mb of ram. The ram is 2 chip though, which I'll get back to in a second. The computer turns on with Chimes of death and

I can't remember where I got it, but I think its from the scsi2sd GitHub repo perhaps. ive attached the Gerber files here of you want to get some boards made just make sure when you solder the connectors on the pcb that you do so the same way shown In the picture in my last post as the connectors are then flipped the right way for a male db25 socket. the original use of the board I believe was to have a female db25 mounted the other side of the board.] btw I don't think it supplys termination power to pin 25 from memory its disconnected on this pcb db252IDC50.zip

More edits, still much work left in the hinges

Sure thing! I do have a PowerBook 100 so I should be able to test everything.

I’m capable of 3D designing the housing but I don’t think we have a good / reliable option for the pins / contacts? if anyone has thoughts then please feel free to share; I would love to come up with a solution for this neat mod which which doesn’t require modifications to the board. edit: maybe a PCB with pogo pins / spring probes combined with a 3D printed chassis to clip it to the edges of the chip? I’ll take a look this evening and see if we have options (sufficiently short pogo pins).

Thankyou! Now that I've finished derailing your thread...

No worries, I'll write it up right now so I don't forget The SeriTek ROM is too large to fit on the IC that these cards are fitted with due to the complexity of the Classic Mac OS support, and it also has some sort of ROM IC check. It will only work with MX29LV040, AM29LV040(B), or the PM39LV040. If a different 040-size ROM is used, it will not properly initialize the firmware. Now, the LV in the part numbers indicate these chips run at 3.3V, rather than 5V. On the generic SiI3112 cards out of China, it's prudent to check whether the original ROM runs at 3.3V, or 5V.
