@stepleton : Indeed, you are correct. From time to time there is a discussion here about these old IBM systems. They’ve been very interesting to me. I had hoped with the forum re-organization that those discussions would be collected here. Alas, not yet. smp

The subject line says it all. smp

I ran CPUTEST and timed it from when the sign-on message appeared until it indicated CPU TESTS OK: Roughly 2 minutes and 7 seconds +/- a couple of seconds for my reaction times with the stopwatch. Again, this is with my Altair 8800c with replica 8080 CPU board running at 2MHz with 64K RAM &...

I ran CPUTEST.COM on my H8 with a Z-80 CPU running at 16 MHz with 64K RAM and CP/M. The results were the same as above, aside from indicating a Z80 CPU, and much faster to complete. smp

OK! I received the CPUTEST.COM file (thanks) and I ran the program on my Altair 8800c with replica 8080 CPU board running at 2MHz with 64K RAM & CP/M. Here are the results:

I sent a DM about my Altair 8800c with replica 8080 CPU board running at 2MHz with 64K RAM & CP/M. All I need is the .COM file to be tested to be emailed to me. I also have a Heathkit H8 with a Z-80 CPU that can run 2, 4, 8, & 16 MHz with 64K RAM and CP/M. Again, all I need is the .COM file...

FWIW, I've been looking any the new lineup since the beginning, and I like it. Will the Mods be moving IBM (Non-PC) topics into the new forum from wherever they are scattered? Thanks to the Admins and the Mods for all the good work they do here! smp

The current OS has an app called 'Automator'. It's been in there for quite a while, but I've never used it. smp

Lots of info and assistance is available from the SEBHC: https://github.com/sebhc/sebhc/wiki smp

Hello again! I also have a Grid 1755 with a couple of power blocks and the manual - also free for the taking if you're interested. smp

Hi Scott, and welcome here to the Forum! I'm also in Southern NH, and I have a Zenith Z100 system with a pile of documentation - free for the taking, if you're interested. The last time I fired it up, it powered up properly, but when I typed a key to boot, the keyboard would get stuck on repeat...

Not an exact match, but I have an Apple IIc+ (3.5 inch internal drive) plus external 5 inch floppy drives. I’m in Bedford NH, just beside Manchester. Please PM if interested. smp

Just to add my personal experience: vintagecomputermuseum will buy systems and parts that are expressly labeled as "does not work" and later put them back up for sale at exorbitant prices BUT forgetting to include the warning that the item does not work. If you buy from this Seller, be ware. smp

PDP-8/e parts (not mine): https://www.ebay.com/itm/Vintage-Digital-Equipment-Corporation-DEC-pdp8-e-Computer-For-Parts-Only-/225861248462?&_trksid=p2056016.m2516.l5255 smp

A list of boards installed would be a great help. Thanks! smp
