Went for a
"last hurrah" today at a surplus shop which is
closing it's doors - what started as a simple inquiry about a
logicpak module I saw on the shelf ended in me taking
home a boatload of modules, adapters and other 29x "bits".
Nice. I, too, have a Logicpak module, but I think I'm running into
firmware revision levels giving me problems with burning very modern
Atmel 22V10 GALs. I did get EPROM stuff working with some Data I/O
custom DOS app to remotely drive the programmer, but I never got logic
devices working. It's on my list of things to do when I get home next
year (that or buy a modern programmer that can handle GALs - my old
DOS-based programmer isn't up to it).
I've done quite a few EPROMs in my 29B - I am hoping to be able to use
the Logicpaks to make use of some of the tubes of older PALs I have kicking
around... But I've never had a Logicpak before - need docs!
I have the Data I/O PC software, but I never use it - I just run it from the
keypad, using the serial port only for upload/download ...
spawned a few Q's...
Give them a shot and I'll answer what I can.
Ok, here goes... Here is a list of the material I
acquired with Q's intermixed:
2 Logicpack modules
- One is 303A-V01, the other is V04-008
303A-004 > Programming/Testing Adapter
303A-011A -> PLD Programming/Testing Adapter
Q1: All of the adapters seem to work (pass self test
on both logicpak modules, except for the 303A-011A
which works only on the V04-008 (self-test hangs on
the other one) - is this normal?
I gather the 011A is a universal module, and needs
the newer firmware of the V04?
Also two of what apparently are ROM modules which plug
into the Logicpak - when in this configuration, there
is NO device programming socket?
- PALASM Design Adapter: 303A-100
- H&L Design Adapter : 303A-101
Q2: How do these work? Info?
Q3: Anyone got documents on the Logicpak or any of these
adapters? (All I have is the Logicpak device list
1 socket adapter 351A-066
- Looks like it fits over a socket on the Unipak 2
Q4: Anyone know what devices this is for? Documents?
1 "Gang Programming Module 28 pin"
- Not the same as a "Gangpak" (which I already had),
this one has a plug-in module for the device type
(installed is: 2708 714-1516)
Q5: Is the device selection module just a "jumper block"?
If so, anyone have pinouts for other devices?
Q6: Any documentation/information?
A complete 29A with Unipak 2
- First thing I tried to figure out is "whats the
difference from my 29B" - I notice that only 4
digits are available for RAM address (less RAM),
and the Unipak2 lists fewer devices than my IIB.
Q7: Manual I downloaded says 8K data ram with optional
expansion to 16K --- yet editing at 4K boundaries
in this unit seems to suggest that it has a full
64k (all boundary edits remained intact) - Is this
a valid way to determine memory size? - Can the 29A
have 64K? (I note that some Unipak 2 documents do
not show devices larger than 27128 (16k), while a
different doc shows up to 27512 (64k) ... ?
Q8: The configuration command (Select B2) shows a value
of B80B - anyone know what this means? How new/old
Any other info/pointers would be welcomed.
