- I dolled out a version of this file I lashed up on the IRC to about 70
- people or so. I assumed it would be posted to a newsgroup directly, since
- not here it is;
-
- <--CUT-->
-
- Project Walker Specifications;
-
- CPU
-
- 68EC030 40Mhz (Proto 25Mhz while custom chip 'Tony' a PLA/GAL')
- Space for FPU. Could be socket or FPU as standard in production unit.
-
- SUPPORT
-
- Real time clock as standard
- Hard drive as standard (size depending on market when manufactured)
- CD (Quad Speed) as standard
- Billed as 1MB CHIP RAM + 4MB of FAST as standard. Likely to be 2+4.
- 2 SIMM sockets. Expandable to 128MB of RAM. (That's right)
-
- ASSORTED
-
- PCB currently 6 layers but expected to reduce to 4 and footprint
- to be reduced noticably. Rectangular optimised PCM layout is far
- cheaper to product.
- Return to dial in-line socketted 8520 CIAs even at greater cost.
- PCMCIA in prototype but expected to be dropped for production unit.
-
- EXPANSION
-
- Standard multicontroller PC style IO chip. Exact model undecided since
- they are largely similar to include in the design and program.
-
- Features; EPP Parallel port, High speed serial port, E-IDE port used
- for CD-ROM and hard drives, Floppy controller * See note.
-
- * Floppy Controller is obviously capable of full speed (not half spin)
- HD floppy disk access but this provides a delima in how to support
- existing hardware illegal DD floppy access. Some sort of electronic
- switching is being considered as well as a physical switch/cable
- relocation to move between the new controller and the standard Paula
- based interface. A change in the HD Amiga floppy architecture is also
- planned.
-
- It's planned that the production unit will accept standard PC AT
- keyboards so that the user may choose their own unit.
-
- OS
-
- Currently V43.1, KS 3.2 will move to a set of 1MB chips which while
- AT aren't sure if it will be provided by THEMSELVES as an retro
- upgrade for existing machines (A3K/A4K and A1200 can take 1MB ROMs
- apparently) they are open to a 3rd party deal at the least.
-
- Contains mainly bug-fixes and small enhancements like the removal
- of the 2GB limit from FFS.
-
- CDFS revamped and bug-fixed to function with Scala etc and obviously
- the new E-IDE interface.
-
- SLOTS
-
- There's one slot located dead center in the motherboard. However it's
- split into two sections so that it may house 2 cards if needs be.
- The exact details on the signals and purpose of each half weren't
- finalised or available but basically one can surmise that one is a
- CPU slot and the other a video slot. Signals will be duplicated so
- that different cards could function.
-
- Amiga Technologies WILL MARKET THEIR OWN PPC UPGRADE! Though it was
- developed in conjuncton with Phase 5, AT will provide the upgrade
- which will contain a new OS on-board and such forth. PPC603 based.
-
- If it's not obvious, it's possible in theory to plug in a GFX board
- in the video half and a 680x0 based accelerator in the CPU half. It's
- not clear if the PPC card will need both or just the CPU slot.
-
- Another major application could be to make a Zorro and/or PCI break
- out board from this slot. No, there are NO Zorro or PCI slots as
- standard though the physical nature of the slot is PCI style.
-
- An additional small 'IO' slot is being considered. 3rd party simple
- hardware projects such as a networking facility, extra serial ports
- or a sampler could be used with this as well as home made projects
- conceivably. This isn't decided, just considered at this time.
-
- CASE
- Yes it's a vacuum cleaner. :-) Seriously the only way to describe it
- is with a picture and I'm sure they'll turn up soon. Interesting
- AT say that the hood could be raised by spacers and such forth to make
- more room internally for a bus board for cards etc.
-
- TIMEFRAME
-
- AT say that the design will be finalised in the Summer ready for
- production. It's not decided of Solectron will be the manufacturers.
- The production unit should be available in the 'Fall' well in time
- for the Christmas season.
-
- NOTES/AUTHOR
-
- I'm the techical staff writer for CU Amiga Magazine. This information
- is important enough to release publically immediately though more
- details, details (very) pictures and interviews with the AT design
- team will feature in the next issue. <sorry for the plug>
-
- All of this information resulted from direct interviews with AT
- staff at the CeBIT show including members of the Walker design team.
-
- FINAL
-
- The name 'Walker' is not the production name! Therefore we call it
- Project Walker. The name is undecided and Amiga Technologies have
- decided to run a competition for the name of the unit! This
- competition will be run through our magazine. Both by writing in to
- the standard address and E-mailing walker-compo@cu-amiga.demon.co.uk
- Just state your name in the body of the mail. That's all that's required
- , if you win I'll be in touch via E-mail to sort out the prize/s.
-
- Prizes; 1st Amiga Surf Pack, 2nd Amiga Magic Pack.
