Hello all - I'm after a Televideo TVI-912B (or similar model) terminal for my IMS 8000 S100 computer. UK based. Preferably working but will also consider non - functional, so long as the CRT is intact. The Televideo TVI-912B was the terminal the original owner had for my IMS 8000. It came with...

Hi All - I'm thinking of buying said terminal. It appears functional - displays text on the screen etc. However - there is a vertical green line to the left of the text from top to bottom. I have some experience of repairing TVs from the 1970's/80's at a hobbyist level, as a teenager - its been...

Just wanted to share - today I fixed my Superbrain QD! After years of trying to fix a Superbrain motherboard I've had since I was about 13 (with a lot of JonB's help, we got it 95% fixed) - earlier today, I had a go at the board that actually came with my Superbrain - and somehow succeeded...

Hi - just posted on a famous online auction site - 2 boxes of 10 hard sectored 8" floppy disks - 2 separate auctions. One box Verbatim, one box Maxell. Maxell are in better condition. Not sure if I'm supposed to post eBay links? Search for Hard Sectored floppy disks and I'm sure you will find...

Hi all, Just a quick vid and rundown of where I'm at with my 12 year Superbrain quest: A pick of the Mboard after all the socketing etc I've done: I've socketed about 15 of the glue logic chips - partly to test them on my ABI Chip tester and partly just so I could see where traces go. I...

I should have left what's well enough alone... I've spent the last few weeks trying to get my IMS 8000 to a point where I can format disks and successfully movcpm and sysgen a system disk copy. I'd got as far as finding and replacing a number of logic ICs and 2114 RAM ICs so finally I can...

Not sure if this is the correct forum... If anyone has the software and / or manual for an MQP Electronics model 18 PROM programmer - please let me know! Could do with copies of both. I've emailed MQP - thought I'd try here in the interim. Any Idea if this early EPROM programmer will deal...

Hi all, I just discovered I have 2 packs of hard sectored floppies - 36 index holes. What would have used them? They came with my IMS 8000 which uses soft sectored disks - maybe the original owner bought them accidentally?

For anyone interested - My IMS 8000 S100 machine is back online after being broke for the last 4 years or so. I recently acquired a rebadged ABI chip tester off eBay. Today I tested all 128 of its 2114 RAM chips and found 2 badduns - a quick robbery from my superbrain motherboard and... Im...

Hi - I've been attempting repairs again on my Superbrain QD for the nth time in 11 years. I thought I'd plot the course on here, post some vids/pictures etc. JonB very kindly tried various repairs on one of my SB boards but had to send it back in the end. I have managed to repair one of my PSU...

Does anyone have any DSDD 8" floppy disks? - preferably in known working condition - before I go blowing money on eBay NOS I need some reliable media for my NEC APC. I did find an old thread about - www.athana.com - on here somewhere but it concluded that they no longer sell 8" floppies. Oh...

Just putting the feelers out - I have a working NEC APC (2 8" drives, colour screen, CPM and MS DOS plus other disks) would anyone be interested in swapping it for a fully functional Intertec Data Systems Superbrain QD? My NEC APC has all the original Manuals, receipts, somewhere I have a...

I just started troubleshooting my DDS-40 XP chip tester. I had started a year ago after turning it on in the cellar yielded lots of fizzing, crackling noises. Opened up the PSU and according to me, could see no visible damage: https://www.youtube.com/watch?v=HR7hgRJOH2c I just opened it again...
