The Toshiba has a weird little setup which is A-1, and its shared with I/O16. It appears I/O16 becomes A-1 in byte mode. But A-1 is not A1. And it doesnt really explain what A-1 ac…

The portable and backlit portable both use 100ns ram. This is my first time making a ram expansion so if I have the logic wrong its a simple matter of modding the VHDL and flashin…

oh man this is pretty exciting. 

I would rather have the Toshiba SRAMs trag. Why? because they are 16 bit and plus they have both an upper and lower byte access mode. This is a requirement for the 68000 as there i…

The portable keeps the card hot at all times however there is a standby signal. But I wouldnt use it. 3.3v logic isnt a problem. The question really wasnt about the design. More a…

i'd deffinatley buy one since i only have a 1mb card for my portable and as the onboard ram is bad there is a good chance the upgrade card might be bad aswell Even at $6.88 a chip…

Isn't the Portable's RAM actually psuedo-static, not static? Just spitballing, but if you could make a board that could take a BGA here's a 4Mx16 70ns Psuedo-RAM that's $5 a head: …

My 5120 doesnt have any expansion cards, and I had noticed decent cards are hard to come by, if not impossible.  Soo...  I have been thinking, I was going to design and build a R…

Thanks Joe from Des Moines. I posted an update on his medical thread: https://68kmla.org/forums/index.php?/topic/23626-medical-update-916-health-scare/&do=findComment&…

I hope Elfen is feeling better soon! Joe from Des Moines sends his best.

Hello, The 17'' PowerBook I had a while ago was badly dented on the left hand and side of the lower case. So I decided to tap the damage out with a tack hammer. I managed to tap o…

Okay. If that's the case probably what I'd suggest is going to iFixit, browsing their take-apart/repair guides, and following one just remove the top case. (The instructions for th…

Its the 17in model. As is, if you have it resting on a desk or your lap, you can't hardly tell that there is something wrong. But if you inspect the machine, yes it is damaged in i…

Might be cheaper to get a dead one in nice cosmetic condition off eBay than to try and professionally hammer out all the dents.

This is not Elfen posting but his youngest daughter, he's in the hospital for observation as it looks like its a bad allergy issue that is he undergoing. Details tomorrow when I ge…

No problem.  John from VintageMicros (http://www.vintagemicros.com/catalog/index.php) also sells small packs of appropriate feet - I can't find them on his site right now, but I kn…

Also, you can use the patched Apple SC HD Setup to format ZIP disks, and the OS will treat it like a regular hard disk. The only disadvantage of this is that ejecting is now a two …

If you plan on using a ZIP drive you will need the Iomega 4.2 driver in order for it to boot the Plus. That also brings up some questions about formatting with third party utilitie…
