Eproms are hard to erase without a close proximity UVC light source. Stickers falling off the windows while inside a machine is never a problem.

[@cybercat1531]

I left UV roms in the sun for 4 months at a time to test this. All of them still read out fine afterwards. Which gives a bit of a hint as to how strong and dangerous the UVC light sources can be if handled incorrectly. I knew someone that used a poorly made erase setup for his work where he kept repeatedy looking at the UV source and suffered accelerated macular degeneration as a result. The stickers really do nothing other than identify the rom chip contents.

[@ProtoHadron]

they're called EEPROMS

[@serqetry]

@@ProtoHadron No, we're talking about EPROMs, which are erased with UV light through the window on the chip. EEPROMs are completely different, they are erased electronically.

[@MrBlakBunny]

My dad told me a story regarding that, back when the telecomm was upgrading to these new chips, the news reporters were over, and sure enough, the person showing off the chips didn't think about the flashbulbs of those old cameras, some of the chips of their massive upgrade were corrupted

[@bradnelson3595]

Also, as much as Steve Jobs wanted to keep it a closed box, it's amazing to see how this old 128 Mac was upgraded.

[@joelavcoco]

The error might mean that there's some bad RAM at a place in memory that doesn't get used by typical software that runs on a 128K Mac. If you fill the memory you might stumble into bad RAM that simply doesn't matter for booting into MacOS and starting a program or 2.

[@douro20]

Any idea how much of the system memory is used for the display framebuffer?

[@adriansdigitalbasement]

I also love machines like this! What a hilarious product too, “For Max lovers only!” Apple used that type of caps in place of X2 caps on some machines. They aren’t as safe as they aren’t X2 rated but they also don’t have the problems RIFAs have.

The only thing I know about holding the mouse button down is that it's supposed to eject removable media on startup. That's the first time I've seen a hardware issue bypassed by doing so. Very strange behavior from a very strange old Mac. I guess that suits it.

[@WhatALoadOfTosca]

Could the error be related to the physical damage on the diskette?

[@bradnelson3595]

@@WhatALoadOfTosca Graham, it would be interesting to run down that error code and see what it says. I always thought these error codes meant hardware failure. But you never know.

[@n1lnx]

Maybe some sort of a security feature wired on the board that disables memory module(s) on power up.

[@tarmaque]

My Mom's boss happened to be at the Flint Center when Jobs first demonstrated the Mac 128k. He bought one on the spot, although he had to wait a few weeks for it to arrive. We were all using Apple ][ computers at the time; my mom at work, and I was learning BASIC on them in High School. (The first class they ever taught in my school on programming.) When Mom's boss's Mac arrived it was the first one in the area, and he loved to show it off. Then a year later he upgraded to a 512k Mac and passed his first 128k machine down to my Mom (his admin assistant.) That was 1985, and I got to type up some high school assignments on it after hours, and print it off on Mom's daisy-wheel printer. Then in another year they upgraded the whole office to Mac Plus computers, and my Mom (who did page layout a lot) got a portrait orientation external CRT monitor which could display a full legal size page. I think it cost as much as the computer, but it was invaluable for her job. (She also wrote a lot of grant applications.) About that time Mom brought home her boss's original 128k machine and we used it for basic word processing for another couple years.

[@fsfs555]

A while back I bought a boxed 128k off Craigslist. When I tried to turn it on, I got a similar error code. Using one of Larry Pina's books, I figured out that it was a memory fault and the book helped me determine exactly which chips were defective (based on the error code). I'm not sure it would still correspond to your upgrade card, but maybe if you could find the docs for it there would be some additional information to help determine which parts are problematic. Anyway I was able to get some NOS memory chips and once I replaced the defective ones, my 128k booted just fine. After decades of use some of these upgrades can develop oxidation on the contacts. Like others, this Monster Mac upgrade displaces the CPU and relocates it to the upgrade board (though some simpler upgrades just fit into the ROM sockets in the same matter) so that the upgrade board itself can occupy the former CPU location on the logic board, usually via sockets but sometimes soldered. If you remove the socketed chips and the upgrade board and spray the respective parts with DeOxit or something similar, it may work just fine when you put it back together. I wonder if it would be possible to expand the ROM on the upgrade card. It looks like it may take extra chips. Booting Mac OS directly from ROM would be even better than a floppy emu setup. Also I'm not sure if it's actually clocked up, but that 68000 is rated for 10MHz (stock is 8MHz).

[@poeskey]

This guy mac's. Seriously though that's very fascinating. I wonder how far he could really push this thing?

[@MichaelAStanhope]

You can see that someone had resoldered the analogue board connections at least once before, which isn't suprising.

[@beenine5557]

I love that what others see as ugly scars, you treat as signs that the machine had a rich life.

[@Solaceon]

I'm much like that too. I collect Nintendo consoles (among many other things) and most bear some pretty rad scars. I fix what's needed for function and use them myself, developing more scars and scuffs to admire later. My DSis are full of audio files, photos, and modded so I wonder whoever winds up with my stuff decades from now would think. I really admire other collectors who feel the same.

[@CollynPlayz]

@@Solaceon yea I collect consoles too I clean them but if there are any files from a previous owner I usually always leave them bc it’s cool to see what life the machine had b4

[@robertnussberger2028]

The wear and tear scars make me less worried of denting or scratching it. I'd make this machine my candidate for writing my fantasy novels.

[@leocomerford]

2:28 Supposedly Apple had a _lot_ of unsold 128K Macs in stock after its launch ... underperformed expectations, so the decision to keep selling the 128K model was almost certainly just to clear out that stock. I'm not an expert, but I assume that nearly all of them ended up being modified significantly, if not usually as dramatically as this one: after all, they were only barely usable unmodified. It's ironic that Jobs set out to create a computing applicance that was unusually sealed and self-contained but instead released a machine that more or less had to be hacked in quite drastic ways.

[@Bendaak]

There was an official upgrade path for 128k Macs to go up to the 512k or even a Plus. 128k Macs are so rare now because a large number of them were upgraded. Even my Mac is a Plus that used to be 128k.

[@RedstoneLP2]

could this be considered a... smart phone?

[@dungeonseeker3087]

PROMs don't get wiped from sunlight (at least not easily), it takes UV light at a specific wavelength to do it and even then, it takes like 30 minutes. Also that upgrade is insanity, the size of that board is absurd.

[@mina47879]

I think you can do it with sunlight but it takes weeks to start flipping bits and months to completely erase.

[@noiwonttellyoumyname.4385]

Friend of mine in high school had one of these, with the exact same upgrade card. He used it all the way through high school, with a 20 MB external hard drive and a second floppy drive. We graduated in 1995.

[@ldchappell1]

I forgot I had one of these Macintosh machines in my garage until a few days ago. It's a 1MB Macintosh with a kind of rainbow hologram sticker on the back " ONE MEG." It is filthy and I'm going to clean it up today. The last time I turned it on was probably in 1998 or 1999. I bought this thing along with a crappy dot matrix called The Gorilla in 1995 at Goodwill for $30 or $40 for the pair. I managed to get onto the internet with it using an external disc drive and a Prodigy Internet floppy.

[@alerey4363]

2:19 Apple had a horrendous history of releasing models with significant more memory (or tiny processor speed bumps) just a few months apart, leaving many users angry; also they were notoriously famous for not making macs upgradeable (and nowadays it's even worse); this lead to a final collapse of the company by the late 90s with a myriad of products, overlapping functions and misleading names which was the first thing Jobs axed when he got back, leaving just 3 lines of product: desktop, portable and pro.

[@NijiDash]

That kinda reminds me of the iPad 2, which came out around a year after the iPad 1. Because the iPad 1 only had 256 MB of RAM, it only saw two major operating system upgrades. With double the amount of RAM in the iPad 2, that one got five major OS releases starting from iOS 4 all the way to iOS 9! I wouldn't imagine many early adopters being very happy about that...

[@retropuffer2986]

I remember a plethora of upgrade cards that added faster processors, memory and other options to the older Macs. Probably most of the 128s and 512s were upgraded to at least 1MB. With 1MB you could run most software into the 90s!

[@kirishima638]

1MB was a stupid amount of memory back in 1985! You'd struggle to use it all up on a B&W mac.

[@will_it_work]

Usually, people upgraded Mac 128k and Mac 512k to a Mac Plus, using Apple's official upgrade path. This had many benefits beyond extra RAM.

[@PetarsPlace]

This phone is literally called the MacPhone TMS1000 (Telephone Management System) It's also one of the few apps that will run on a stock 128k. I searched for nearly 15 years to find the software for this and a relative of one of the engineers that coded the app sent me the software for this. I have the box/manual/device in my collection for many many years. The software worked over the audio jack to dial the phone numbers, and you clicked on rolodex type entries that you create for calls. It will also track your call times and log length and any notes you took. I see he found the copy of the software that we got uploaded to Macintosh Garden too! Excellent! Just need to install a regular telephone handset and you can use that phone again with a voip ATA device! The system even works on the Amiga 500 with the Amax II software and using the Amiga audio out.

[@BenInSeattle]

As you probably know, holding down the mouse button ejects the floppy disks. But that makes me wonder if it is a boot disk issue. Do you get the error with the SCSI addon removed? Is it possible that it is attempting to boot off of an external drive? [Edit: Never mind. I just tested on my MacPlus and holding down the mouse button *also* skips the RAM check. I never knew!]

[@greggv8]

Just giving all the sickened chips a push will likely fix it. That was step #1 back in the day for PCs that would power up but did weird things. Push on every socketed chip and listen for the *crick* as they seated farther into the socket. That would cut through mild corrosion. If things looked extra dirty then pulling and putting back every chip would scrape the pins and contacts better.

[@UpLateGeek]

I remembered I completely forgot to comment about the EPROM thing last night. As other have mentioned you pretty much need a UV-C light source to erase the EPROM, even leaving them in direct sunlight for short periods shouldn't be a problem. I guess if you happened to hold them at the perfect angle perpendicular to the angle of the sun, there's more of a chance it would be a problem, but you'd likely need to hold it there for some time before a single bit were flipped. But in regular indoor lighting there's almost zero chance you would corrupt the data if you left the cover off. That being said, I still cover my EPROMs with foil tape after burning them. Mostly because I think it looks cool, but also partly because an overabundance of caution does no harm. To be honest, even labelling it with a Brother/Dymo label would be enough to protect it from all but a strong UV-C source. And then I'd probably be more concerned about the damage to the label.

Nice find, fun stuff. Just wanted to point out that it's unlikely that floppy belonged to that Mac since it's an HD floppy and the 128k's drive wasn't capable of working with those. I've got a 512k and what I like to do with it is boot a basic System floppy which loads up the HD20 driver--then the boot process is handed off to the FloppyEmu (love mine!) running in HD 20 emulation mode. With that setup, you can actually have a fairly functional machine (the downside being you need a working floppy drive and floppy disk at boot time). You should really see if your floppy drive works (and clean it and lube it). Anyway, looks like a fun new toy and I enjoyed your vid, thanks!

In theory it could of also been a dial up modem for the MAC but I guess they didn’t go with that since it would be more practical to have a second phone like connected to a dial up modem expansion card in the MAC so it could stay always connected to the network, including when you are talking on the phone with others! :)

You do not have to worry about the sticker falling off unless it is in direct sunlight for a long time. Household Lightbulbs do not give off UV light unless they are for growing plants. Same with TV you can watch someone weld on without worrying about damaging your eyes with the UV. It takes a lot of UV light to erase one and as to be in a contained box of very strong UV lightbulb being used for a while. Even in direct sunlight, it would not do so. I would not take the chance that it does not do so in sunlight. Someone on here already did a video where they tested this out. And found it not to be true about the sticker having to be on them.

Might be worth getting something like a tl866ii so you can dump and write E/EPROMs, especially when dealing with vintage/rare tech like this. Got one myself which comes in handy every now and then such as testing custom Kickstart ROMs on my Amiga and replacing the fried ROM on a MD/Gen game. Also got a cheap UV eraser on Aliexpress.

Now, that's an impressive piece of history.
