ISO: 68000/68010 CPU board for ZAX ICD-178 (CPU S-813)

Hi all -- I picked up a ZAX ICD-178 in-circuit debugger in the hopes of using it to help debug / reverse-engineer a couple of 68k-based machines I have.  This unit can work with 68000, 68010, and 68008-based machines, however a different emulation CPU module is used for the 68008 vs. the 6800

Thats amazing Brad! Good job. The amazing is that you have working board bucket, that has to be the rarest thing out there in 4051 hardware. I need to follow vcfed and you guys more, you are definitely on top of the hardware. Randy From: cctalk on behalf of B

Re: sun model 47. code 4/40 does it have the nvram with battery?

Yes. It is next to floppy in the upper half of the chassis. There is a 50-pin (IDC connectors) ribbon cable that goes down to system board at the bottom of the lower half of the chassis. The chassis splits in the vertical middle in a, if looking at the chassis, fairly obvious place. Because of

Hi  Alan - The  hard drive is same  size cabinet    with  I  guess a  SCSSI   cable.  I  will have  to  look  at  it   further...   wonder if starting it  out on  a  variac   would  help the capacitors  like  I  do  with the old radio sets  here in the museum  ed#   In a message dated 12/1

Re: sun model 47. code 4/40 does it have the nvram with battery?

Well, as I said, in my experience, the NVRAMs that you can buy new from Mouser work good enough. And the mod to the original battery isn't that hard to make. In my experience with IPCs, the bigger problem is the power supplies. If the PS on the IPC that you have now doesn't need to be re'cappe

I'm not sure how many of you who are on this list are on the vcfed.org forum, but just for those who aren't, with the help of Dave and Monty from there, I have recently restored a 4051 I bought a couple years ago to working condition. Last night with their guidance I connected it to a Tektronix de

BA11-C and BA11-E mounting boxes

For some actual content about classic computers (instead of flaming about various ideas for improving existing systems), I think I've worked out why the BA11-C and BA11-E mounting boxes have out of sequence variant codes. It's obvious the variants were not assigned in creation order (the /44 and /
