Woz IIgs w/ AE Vulcan 20mb HDD

Recommended Posts

LOL I just unplugged the IDE hard drive from the Vulcan power supply..The power supply turned on and powered the IIgs w/o the hard drive in it... so then I plugged it into just a bare power cord from another computer... the disk spun up fine.. so I put it back in the vulcan powersupply and it works fine now?

What did I tell you about the flat-out-A W F U L reliability of those drives?

Just get rid of the damn drive. It's the source of all your problems right now.

Won't work. There's only a few drives that'll work with your card. If you changed the EPROM to the Vulcan Gold then there's more than a dozen that'll work. Any drive that'll work will be from the same era your drive was made.

The drive can be replaced with a Compact Flash but finding one that'll work is difficult. I borrowed CFs from a lot of friends obsolete cameras before I found some that would work. The nice part is that they're a lot faster than the drives. The odds of finding a compatible CF go up if you have the Vulcan Gold EPROM

Again, give it a 32mb Compact Flash card and it's happy.

 

yah, the hardrive ended up smoking, so I took it out and I removed the vulcan parts for the time being.. I need to get a CF card thingy.. I dont know where to find one!!

I have a bunch!

 

I'll have to look at them, but some are 32 MB, 64 MB and maybe a couple are 128 MB.

 

Are there any brands/models that are known to work reliably?

I used a card branded by Kodak but one with Canon or Nikon branding might also work. On paper any CF card 32mb and under will work but god knows how modern cards behave with controllers this old. It's once you go over that I can't really say as you exceed the maximum partition size for ProDOS.

The Vulcan supports multiple partitions, so 32MB isn't a hard limit. The problem is that the firmware only supports a limited amount of CHS combinations, similar to the old BIOS drive types before "User Defined" came about. I wouldn't be surprised if the table is close to or identical to them. The Vulcan ROM is completely inflexible and refuses to work if it detects something not matching its on board drive table.

If you search ebay for something like "cf card lot" you can often come up with auctions for a dozen different cf cards of low capacity for fairly cheap.  Maybe one or two will work...

Also, I wouldn't even bother with the Apple RAM card. ggLabs sells a 4MB card on ebay, no worries about running out of memory with one of these. If you need to get a disk image to the IIgs, use ADTPro (or the FloppyEmu if you have one). Power Mac manual inject floppy drives aren't all that reliable at making 800k disks.

 

The Vulcan controller is notoriously picky about what type of drive is connected to it. Very few CF cards will actually work with it.

 

I got the 4mb RAM card from gglabs and I can testify that it is awesome.  Well worth the money.

Thanks for the info.

 

Now... A Woz IIgs as I remember is  modified ROM 0. Modified how, I do not know.

ROM 0 IIgs' were from the first year of production (Sept '86 to Aug '87,) including the first 50,000 limited edition "Woz Edition" (I had one when new!) I believe GS/OS requires ROM 1 or newer and all owners of a ROM 0 IIgs were offered the free upgrade to ROM 1 (chips were upgraded, motherboard the same.) No further upgrades were offered for the IIgs (ROM 1 to 3) as 3 was not required for software.

All Woz IIgs were originally ROM 0, then Apple provided a free ROM and video graphics chip upgrade to ROM 1 less than a year later to run newer software written later than late 1987. Tools in ROM were also buggy, fixed in the ROM 1 upgrade. Very few ROM 0 IIgs machines are left as they weren't totally usable with later software, so they're a rare find if just for historical sake.
