ROMs are based on M5M27C101JK, which he said is EPROM. I'm not seeing a datasheet for that, or any that are similar enough, so just I'm assuming that this pin is a /WE. Most mode…

If you need more parts, I'll be glad to give you my Radius 81/110 sn JAE534014629S. But I need a favor. The video no longer works, probably due to the corrosion on the connector …

That sounds like a hack to allow programming an EEPROM or Flash module in place in the machine. Is your IIfx SIMM built out of ROM chips or EEPROM or Flash chips. Hmmm. Must be…

Great thanks too all, I make a diskette and everything loaded !! But, HDD is dead (((((( with the start it begins it twists itself and immediately it calms down. Where i can buy SC…

I have an 80MHz version. Click to expand... Someone in another thread was asking about changing the 9150/80 from 2X the bus speed ( 2 X 40MHz = 80 MHz) to 3X and running the b…

the one that would let me expand ROM to 1024k, is connected on my IIfx SIMM to /WE (write enable) on each ROM chip. Click to expand... That sounds like a hack to allow programm…

With ROM, it skips the "real" A0 and A1. This is because each address on the address bus is sent to all 4 ROM chips. Because there are 4 8-bit ROM chips, each address requested f…

Trivia note: Kurzweil synths were designed, and the company founded, by Ray Kurzweil. Yes, that Ray Kurzweil. If the software editor controls the synth via MIDI, then it ought to…

Yes, System 6.0.8L, not the regular System 6.0.8. There is a difference - the regular System 6.0.8 will boot any Macintosh originally designed to run it, but not the Classic II. Sy…

That is an awesome haul of vintage keyboards there. And that MicroMac '030 upgrade is just :O - what an unexpected bonus!

I have been away from the pre-mac Apple world for a long time. My parents bought for me a Franklin Ace (clone) when I was a kid, but they never got me software except for some lame…

everymac.com tends to live up to its name.

Here we go. According to my notes, I have a PM9100/120 S/N XB51800V4US, a WGS9150/120 and a WGS9150/80 S/N XC44405V36R in the attic. I kind of wonder if the first two listings …

As promised, here's a shot of my new Pile-o-SPARCs™! Notice the incredibly disgusting SPARCstation 10 on the bottom of the pile, as soon as I get the chance, I'll gut anything els…

One of these days I'll get all this stuff sorted out and offer up the excess for sale. Click to expand... If you ever let go of the 120MHz models or mobos, let me know. My case…

Thanks. The seller says there's a minor boot up issue but that it works fine after that. I'm guessing there's a conflict between the PCI cards or possibly even a bad memory stick i…

Nice score!

Managed to pick up a PM 9600/300 to go with my 8600/250. Still not found a full blown 9600/350 that I could afford yet, but this will do for now. Seller says it came from a graphic…

I think one or two macs used this video interface... Click to expand... Nah, no Macs ever used it, but some Apple displays did - the Apple Portrait Display and the Macintosh 21…

filipp76, Your model Macintosh needs, at minimum, System Software version 7.0.1 in order for it to work. 73s de Phreakout. :rambo: Click to expand... Actually the minimum …

Yes, the IIsi is also a great machine. I rescued mine from being scrapped at recycling event. It has been a great machine.

Is the floppy drive in the Classic II known to be working? Perhaps it needs to be cleaned and lubricated.i don't know ((, how to clean floppy ? Click to expand...

filipp76, Your model Macintosh needs, at minimum, System Software version 7.0.1 in order for it to work. That's why it ejected the System 6.0.8 floppy. If you'd like, send me a …

Just today I picked up a Plus with the same D logo on the front, except mine is a blue sticker rather than an embossed one. I'll put some pics up soon, after I see if it boots, and…
