RE: N8VEM projects

["Andrew Lynch" <lyn...@yahoo.com>]

Hi!  I think its time to update the N8VEM projects list.  Any updates or corrections?  Are we missing any projects?

 

Thanks and have a nice day!

Planned

ECB Active Terminator

      - status: not started.  Has anyone built one of the ECB extended backplanes?  Do they work?  Do we even need an active terminator for the new backplane?

 

ECB WD2793 FDC

      - status: not started.  It has been a while for this one.  John is working on an S-100 ZFDC board which uses the WD2793 so it probably makes sense to let this one wait until the S-100 ZFDC is done

 

ECB Dual GIDE

      - status: not started.  Max, we were working on this at one point, I seem to recall.  Any progress?

 

ISA Prototyping Board

      - status: not started.  This project is low priority and waiting for some of these others to clear out first.

 

 

Active

ECB Host Processor Redesign

      - status: PCB completed, awaiting manufactured PCB order

 

ECB RAM-Floppy

      - status: in work.  Wolfgang requested to hold the ordering the prototypes until after December so he can do some updates.  On hold pending resolution.

 

ECB uPD7220 GDC second prototype

      - status: second prototype PCBs ordered.  Should arrive late Dec 2010.

 

Home Computer

      - status: initial prototype PCB designed and trace route optimization underway.  No estimate for completion yet.

 

S-100 Console IO

      - status: first prototype board ordered and sent to builder team.  Build and test underway with expected rework in progress.  Second prototype PCB looks likely given scope of changes.

 

S-100 ZFDC Intelligent Floppy Controller

      - status: second prototype board ordered and en route to John.  Fixed the numerous problems with first prototype.  Looks solid and probably a manufactured PCB will be ordered in couple weeks or so.

 

S-100 68K CPU

      - status: first prototype board ordered and distributed to builder team.  Initial build and test under way.  See Douglas Goodall wiki for update on status.

 

PICE

      - status: Nothing on PCB, prototype is in construction.  No progress recently.

 

SCSI2IDE

      - status: concept board designed.  Ready for prototype but likely OBE.  Probably headed for permanent stasis.

 

MSX cartridge reader:

      - status: initial prototype board status ordered.  Should arrive in late Dec 2010.

 

MSX cartridge board:

      - status: designing board in work.

 

SBC-188 rev 1

      - status: Rev 1 PCBs on order.  Expect delivery in late Dec 2010

 

4MEM

      - status: Initial PCBs on order.  Expect delivery in late Dec 2010

 

 

 

Under Consideration

S-100 Propeller prototyping board

S-100 Bus Exerciser

S-100 SCSI Interface
