If we go by that logic this whole project would be a desaster ... afterall the InterWave chips I'm using are precious and very rare spare parts!!!!!!1one. Friend, rare? How much do you need? 100-1000-10000 pieces, This is all in stock) My response was ironic. I'm aware of various chip brokers …

Alternative is so simply break off the excess on the Vibra brackets, as I did 😉

ARGUS RC1 #03 reporting for duty! 8) Wow ... soldering looks amazing :) Now... the card is desperately asking for a bracket, has the community effort to produce these for the production run gone dead? I'd be willing to pay (assuming it's a reasonable amount) in order to have a good looking metal …

Yup ... nothing out of the usual I'd say 😉 On the other hand, I'm working ~70 hours less per month and still earning pre-Corona money, so that's cool.

See: https://www.vogons.org/viewtopic.php?p=849743#p849743 For my personal situation ... I guess I never updated you guys.

Glad to hear parcels are slowly reaching their destinations 😀 Now if only DHL would refund the bounced parcel (started a claim 2 weeks ago).

This is the most "teaser" like you'll get for a while. https://www.youtube.com/watch?v=uQwjjuAjmz8 Once the initial run is over, I might be able to deliver a few more, as I have an excess of InterWave chips and the PCB design can be replicated as many times as desired. But no definite plans there …

I'm determined to finish this project this year so I can be done with it and people can enjoy their cards. With the first cards arriving now, I'll set a 3 months testing period til the end of July 2020. Plan is to order and ship the final design in August.

EDIT: Oh and BTW if your memory was SIMMs or 5V DIMM stick then that could be toast too, as well as CPU and any ISA cards. Best to test everything in a known working mobo. And potentially kill the working config along? Let's resort to finding out what happened first, before killing more good …

Yup, you can be pretty sure you killed either the PSU or mainboard for good. The Debug card being stuck …

Basically all 256k*16 or 1MB*16 DRAMs in a suitable package should work, speed shouldn't be slower than 70ns (80ns might still work but is unconfirmed). I salvaged mine from old EDO RAM sticks (1MB*16 types) or VGA cards (256k*16 types).

Substituting AT93C66SC with CAT93C66VI-GT3 should work. As for the MS6308, there's some replacement type which I successfully tested, I'll make sure to let you know what it's called when I get back home from work. EDIT: TDA1308 from NXP is a substitute for the MS6308

Basically what Tiido said. I'm in the very lucky position to still have very good eyes so I barely need to use a magnifying glass. If I manage to get a decent ancor point to rest my hand/fingers on on the board I usually align chips using my fingers (freehand I have a slight tremor/shaky hands that …

All RC cards have been sent off :) @Thermalwrong: I've soldered worse QFP packages by now and adapted from using hot air to using an iron + wick ... i.e. EPM7128STC100 are quite a pain with their tiny package - less pins than an InterWave, but a considerably tighter pin-density.

That's the current plan ... I might have underestimated the effort of soldering ~200 InterWaves for the final run, which is prolly why I've been quite lethargic the closer the project got to being finalized. I've recently announced that change of plans on here.

Guess who's behind shedule again? 😀 I'll go grab shipping labels tomorrow, so if you haven't please send me your current shipping adress asap so I can send out the prototypes (so far I've recieved 2 adresses from 12 testers [-2 since there will be some combined shipping]).

That's cool :) I just wanted to order from your shop again and was collecting a list of items I need (i.e. VRAMs for the Sprinter). Feel free to include them with my next order which will be placed soon-ish ... the previous one has already arrived (ZXM GS, Compact 256, Atm Turbo 2+), still waiting …
