I have a Makerspace in Wall NJ (Computer Deconstruction Lab), near the VCF/MARCH museum at InfoAge. Someone has asked us to recover their photos from a disk that seems to have lost it partitions. I was able to image the entire disk with Linux and dd. But I can get near the partitons (Linux can...

I also grabbed: https://github.com/robin7g/swtpc-sound-card and I thought I found some python code to convert sound files to asm. Saw a Youtube video that had it play the sound file for the War Games "... play a game" I'll need to see where that is. Thought I added it to my notes. Oh it's the...

It's a Newtech Model 68

YW, good luck and let us know how it goes. :) It's going to be a while before I finish up my 68008 boards (but I will finish them).

I recall reading a few but Midnight Engineering was more business than electronics/software. Kind of like some of Don Lancaster's stuff. Odd I've probably read more of Don Lancaster's stuff than any other author. :)

The Z180 Lunch Box was from his Byte days. The HCS II was from his CCInk days. Loved reading both. :)

Yes, he had a pellet fed stove and he controlled the BTUs produced by controlling the pellet feed. That was in the later magazine Circuit Cellar Ink. Met him once at Trenton Computer Festival. He was interesting but his Z180 Lunch Box more so. :)

Dang not sure how I missed this. I have a bunch of Steve's stuff (he gave it to me with the HCSII stuff). I have a bunch of stuff to repair. Most of it is his Z180 stuff. Micromint sold it (might still sell some of it).

Yes this is very cool! :) I'll start without the disk drives. I'm hoping that I can boot to the ROM monitor (GMXBUG) and then dump the ROMS. I don't think there are many ROMS that work with the video card out there. I'll then play around with the boards and see what works. I have a Peripheral...

BTW, I used the 68008 and 68000 Hazelwood Uniquad. Nice boxes with OS9/OSK. We used them for development. Would love to get one but will settle for the 68K boxes I do have. :)

I'm working on a 68008 board for my SWTPC clone (Corsham SS50/SS30 boards). I call it the MP-A8 (SS50 bus) and MP-A8A (68Retro SS50ish bus, has 1M on board SRAM, ROM and MC68681). While the MC6850 and MC6821 are 6800 chips, the MC68681 (2681) are 68K chips. They support the DTACK and interrupt...

I would love to get a schematic of the video card but I was seriously outbid by 2 bidders on Ebay. Docs went for over $100.

Oh yeah, forgot to 'splain: SS50 bus section 3 - 16K SRAM boards 1 - 6800 (1MHz) CPU card 1 - Single Density Floppy Card 1 - Gimix Video Card SS30 bus section (in order, left to right) Microware 6850 card 3- MP-S (6850 card) A sound card Microware 6850 card Clock card MP-LA card No idea on...

Finally I get a chance to work on the Ghost! I have it on a clean section of my desk. I'll get the Commodore monitor hooked up and see if we can get video out. I'll also hook up a serial cable to the first few serial cards. I'll need to test the serial keyboard I have (TV950 keyboard...

Yes, definitely dump the ROMs, take pictures, the works. :) The gentleman on EBay had it up and running so reforming the caps might not be necessary. But I'll get advice on that before I power it up. I need to figure out how this thing booted. It has a video card and probably had a serial...
