Hi,
Time to de-lurk!
Woot - After gearing up for whet feels like 10 + years, I have finally been able to score an IMSAI 8080 chassis with front panel. It is in pretty good condition, but bare - there are *no* boards present. That was not a worry, as in about 2009, I brought a set of Solata boards from eBay that were unpopulated.
So far, I have populated the Solata CPU card which has provided me with a functioning Z80-A cpu, and a Solata mixed memory card to give me 2K of RAM.
With a little love being applied to the front panel, I can now single step the CPU, deposit data into memory, examine from memory, and output data on the 8 LEDs on the front panel. I currently can't read from the front panel port (at location 0xff), but that can't be complex
I have ordered a 65K dynamic memory card, and just have to sort out a SIO card. I do have the Solata 2S+P card that just needs to be populated, or I can pick up an actual IMSAI card from ePay.
In all, I am getting there
A couple of questions:
1. Comparability with IMSAI software is important - A cursory glance of the Solata board looks like it may be compatible with the IMSAI SIO, but does anybody here know for sure?
2. My machine has the 110V only PSU - I am in Australia..... While I am currently running through a step down transformer. Does anybody know where I can source the transformer that had the dual primary windings? I don't mind paying shipping from the USA.
3. I was 2 days late to the auction site, and missed out on a red paddle lever - The right hand red paddle is partially broken - I have an email in with Todd Fischer from the new incarnation of IMSAI, but there has been no response. Can anybody assist with a replacement?
I know I currently have an IMSAI box, and a bunch of non IMSAI parts - I am wrestling with what is actually important to me?? Do I want an *actual* period correct machine, or something that looks wonderful and is functional? I am willing to accept guidance from others. I have a substantial collection of old gear, including a PDP11/10, a 11/34, a heap of other machines from the mid-late 70's including TRS-80's, Apple IIs, Comodore 64's, and a Dream 6800 and am very happy to have this machine compliment my world.
