Data I/O Model 29 info?

Hi Ethan, 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 ... 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 + Adapters: 303A-002 \ 303A-004 > Programming/Testing Adapter 303A-006 / 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 .TXT) 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 is it? Any other info/pointers would be welcomed.
