MJ's stuff

Well, I haven't been 'collecting' for very long, so my list of machines is pretty short compared to most here. But I'm pretty happy with what I have! I really got into this to try and have some fun and connect with my Mac roots and meet some other people who have the same interests. I like finding these machines local or through personal contacts because I really like getting the personal details of the machines I find... find out who used them, why, why they are moving them on, etc. It gives it more of a connection. So I'll try and add a bit of info on each machine here.

Important note - all but one of these machines work today! and the one that doesn't will soon. smile

My journey into vintage Macs started when I hunted down an SE/30 at a local e-cycle shop. I had volunteered at the shop 10-15 years ago so had a connection to the place. I wasn't specifically looking for an SE/30-- I knew they had a Classic, but then the moons aligned and the guy who was there was very helpful and willing to sell me a nice working SE/30 which he had on a shelf in back.

So here's the SE/30!

DSC03551_zpsb62a4849.jpg


I read a number of posts on the SE/30 cap issues... and had my first experience with taking apart a compact. By some miracle I already had the right screwdriver, which allowed me to dive right in. Caps were, of course, leaking all over...

photo3_zps43ec17d9.jpg


... and that's when I first met Charles when he helped with the recap. In addition to that, he got me one of his 10k eServer drives. Later I added one of Max's special adapters. Here's how it's rigged up with their parts:

DSC03555_zpsa6ff7a54.jpg


Awhile later, a 512k popped up on Craigslist VT. It was funny because it was for sale in the same town where my Mom and Step-Dad live, which is incredibly small and kind of in the middle of nowhere. So I corresponded with a nice older lady and picked it up. Turns out she was the daughter of the original owner who was in his 90's and wanted the Mac to go to a good home. He spent YEARS with the thing, using it primarily as a word processor. Lots of copies/versions of Word came with this one. Charles cleaned up the AB and I got the floppy drive working again, which was totally jammed up with crud:

DSC03538_zps09e35142.jpg


Next came the 6100, pretty much out of necessity in order to get software onto the two compacts. A nice guy on LEMSwap was giving away two of them along with a 14" Multiscan, so we drove down to Massachusetts one day and loaded it all up. The two 6100s became one decent 6100, a few spare parts and a pile of spindlerplastic.  I used the 6100 for awhile but now it sits here (can you find it in that mess?)

DSC03552_zps71647920.jpg


The 14" Multiscan had a broken hinge (don't they all), so I created a new one out of some styrene. I have spent a lot of time building scale models... so I am pretty comfortable with plastics, which comes in handy when trying to deal with this spindlercrap:

DSC03544_zps8037a86f.jpg


The 7600 came next, mainly because I had a bit of nostalgia and really wanted to play Warcraft 2. The game has a min requirement of 60mhz but simply wouldn't play well on the 6100. So this is where I deviated a bit from my somewhat standard non-eBay policy and I won this 7600 in an auction. I justified buying on eBay because it was advertised as being in Concord which is 45min south of me and I had planned to pick it up and get some info on it. Things didn't work out with timing, so I opted to pay the $20 shipping and I was glad I did because for some reason it came from North Carolina. Weird. It's history remains a mystery. So this showed up with an unadvertised Newertech G3 400mhz upgrade and 600+ MB of RAM. Score! I picked the old Apple Monitor up at the dump smile This one's my real workhorse and I am able to use Classila nicely on it to download software for it and my other machines:

DSC03553_zps1b5d039d.jpg


The Plus came from a nice guy in Littleton, NH which is a fun, small town to visit. Great diner there, and we made sure to stop at it for lunch after picking up the machine. This one was originally bought by a UNH student who had tons of software on floppy disks (more on that later) and an external SCSI HD. She sold it to the guy in Littleton who I think was big into D&D because there were a lot Hypercard stacks and monster creator software. I'm not really into all that, but if anyone wants any of that, let me know.  Charles fixed the AB on this one, which had a bunch of issues. JHolt supplied me with the zip drive, and a special shout out to Scott Baret who hooked me up with a T15 case screw! The floppy disks were all bad, sadly enough, and I blame them for the demise of several floppy drives. This Plus is sweet!

DSC03549_zps2955b5ca.jpg


The final piece is this exceptionally nice looking Performa 475 which came from CT. All of my machines have some degree of yellowing, but this thing is practically in perfect condition. The only issue with it was it had absolutely no sound-out. I got the LB and PS off to Charles for recaps and to see what was up with the sound issue and it turned out to be a rotten via. He's helping me with another board though... until then, this baby's missing some key pieces big_smile

That's it for now! I've got a couple more on my hit list, so if I ever get ahold of them, I'll post!

Re: MJ's stuff

That's actually a really nice collection! And it's good to see them all getting use.

A lot of the 73/75/7600s have hidden gems in them like that, PCI cards, CPU upgrades, you name it. You can really cram them full of stuff. My 7300 has a 800MHz G4, a Rage Orion and an OrangePC card, plus a gig of RAM and two 18GB SCSI drives.

Re: MJ's stuff

Thanks guys!
Classic- what do you use your 7300 for? I really like this 7600-- it's incredibly versatile and the outrigger case is pretty easy to deal with. I don't have any other cards in in right now, but I'd like to get one of those Sonnet Tempo SATA cards and throw a big drive in there as it's kind of the hub of all things Classic software for my collection. Classila works real well on it smile

JT - thanks! I didn't show you all the glue required to keep the rear grill together. It's pretty much a MultiSuperGlueScan14 at this point. Definitely not the nicest monitor in the world... but works for what I need it for tongue

Re: MJ's stuff

The 7300 is mostly for games now. This one used to run NetBSD and act as a database server, but it now plays a crapload of games. The MDD is my development system.

Do you still play Warcraft II on that thing? I still have all my warcraft games up to and including WoW which I play religiously somehow...

Hey markyb! haha yes! In fact here I am getting my ass handed to me on the Great Portal level yikes

DSC03557_zps07f6c1fa.jpg

That's great you still play- Warcraft 2 got me into gaming in the first place. I still like the RTS type games! I was big into FPS for awhile but my eyes are pretty shot now so I steer clear of them.

Re: MJ's stuff

Well, my Performa 475 is all back together... I hadn't had a chance to post this, but here is the logic board. This one's pretty neat because it has an actual ROM slot! It's an early version.

DSC03562_zps4ea09513.jpg

It would be cool to do some stuff here like what dougg3's ROM can do with the SE/30. That's all way, way above my level, but fun to think about. smile

Re: MJ's stuff

How about changing the startup chime to the death chimes, vice versa being uninformative but tempting? wink

I've also got a ROM Slot implemented 475/605 . Have the ROM hackers figured out how to wedge higher storage capacity into that slot yet?

Was that the hang-up with the 475? I wasn't sure what it's deal was, in terms of rom-hackability... I guess you can hack it to prevent RAM check at boot which can be helpful, but I guess I assumed the other bonus features weren't available because... well... because someone tres smart just hadn't made it happen yet?   Maybe motivation and interest isn't there on the same level as the SE/30 because ROM slot 475's are not as plentiful in the market? I'm grasping at straws. smile

Re: MJ's stuff

Most 040's don't address much ROM.  1MB I think?  It has been a while, but they don't address enough to do a bootable ROM disk.  At least from the system ROM SIMM.

Re: MJ's stuff

btw love warcraft smile     So as Steve was saying over at BMOW,  like with the plus rom, there was 3 megs in-between the SCSI and SCC in the memory map, but in order to access that some more logic would be needed, etc.  so i would assume that to be the same for the LC475, someone like your self rob,,, would have to really want it bad, then it could be done?

Re: MJ's stuff

User mode of the Motorola 68060 is object-compatible with MC68040

he Motorola 68060 is much faster than its predecessor, mainly due to higher clock speed, superscalar design, larger instruction and data caches and branch prediction. Under the best conditions the 68060 can execute one integer instruction and one Floating-Point instr

oh Whoops smile

The 68060 CPU uses lower voltage - 3.3 Volt as opposed to 5 Volt for 68040. Lower core voltage directly translates into lower CPU power requirements. For example, 68060 66 MHz dissipates as much power as 68040 33 MHz.

Re: MJ's stuff

Well, with the ROM SIMM, that at least lets you modify ROM and maybe cram a driver in there.  Then anywhere there's available address space, insert other hardware.  Around the time of doing the ROM SIMM driver, I was contemplating doing a bootable ROM card.  I have a hacked up 030PDS proof of concept card from back then.  I think I posted pictures and stuff on 68kmla, but pretty sure those are all gone now.  I can't find them anyway.  I was able to dig the card up and take some pictures.  It hasn't held up well in the box I dumped it in when I was done:
front.jpg
back.jpg
And here's an old screenshot of the card detected and declrom read:
030pdsdecl.png

Anyway, stuff can be added anywhere, and with a ROM SIMM, even if it can't address much, it can at least be used to make almost anything else bootable.

Kind of like the MacRescue board where it has up to 2MB of RAM that is not contiguous with system RAM, but exists higher in the address space, and with the proper software, can be used as a RAM disk.  Without taking up any of the 4MB of system RAM.

Re: MJ's stuff

rob that is pretty awesome man. --- i like how it says "bbraun 030PDS"!!!!!

so with a hacked rom... then a card like that... one could come up with all kinds of nifty concoctions.

I really do understand why the IIx / IIfx / IIcx / IIsi / IIci - SE/30 is just so great, with a nice convienent 8mb rom map!

Re: MJ's stuff

Well, if the card goes in an actual Slot (like, slot manager slot), the stock system ROM can boot it (although only if it is set as the boot device in PRAM, the stock ROM doesn't search add-on cards for bootability).  I just show this as an example.  Those little chips are ANDs and NOTs IIRC, and just do the address decoding for where in the address space the ROM should show up.  It can really be anywhere you want, as long as it isn't taken by something else.  That's why I made the caveat about "from the system ROM SIMM".  The image can reside pretty much anywhere you can make a device to put it, and a programmable ROM SIMM lets you boot from it, even though it's not large enough to hold the bootable image.

Re: MJ's stuff

I love these tangential posts, but I think we need to start sending the offshoots to their own topics wherever and whenever. I've muddied up mcd's stuff quite enough already this last go-round.

Thanks for re-posting your pics, that board is one of the things that inspired Project 30. Have you got that wiring layout handy? It'd be great if we can expand upon your DECLROM decoding interface. I'm taking a shot at developing a "Swiss Army" ProtoBoard for the IIsi/SE/30 PDS that's reminiscent of the " ISA bus interface IC ready" ProtoBaords JDR used to sell back in the day. It'll be one horrible mess of multiple double PC board interconnect madness hanging off the outboard side of a PDS passthru  that's high enough to clear the outboard side of the IIsi and the frame of the SE/30 in my cutaway "Visible Plus" Bucket that's morphing into becoming a ZipMac Plus/30™ all of a sudden. I just need to gnaw off the backplane port section next.

gkNb2o.jpg

I did the routing/graphics and silk screened enamel resist on PCB blanks to etch all the prototypes for my Font Emulator startup (4 ROMs at a time) back in the day. I REALLY need to get my hand back into something like that kind of blast from the past. Such might aid my efforts to remain as sane as I've ever managed to get here in the present. I'm coming up on my sixth mental health birthday come April Fool's Day and not doing so well at getting there over this Holiday Hump. hmm



edit: I posted the pic to show (just barely) the outlines of the PlexiPassthruProtoBoardPrototype(R) and just spotted the side of the plotter I'll be using to cut film for this insane project in the pic. wink

I'm just seeing this all for the first time... it's fantastic! So you finished up this proof of concept, declared success and moved on to other things? It's really awesome, what you have there.  I haven't gone hunting on the other site for it, but it sucks that the pictures would be missing. Into the rabbit hole I go...
